00:00:00,480 --> 00:00:06,400
So, there's this really cool kind of trick effect that you can do with an LCD

2
00:00:04,240 --> 00:00:10,880
or LED monitor where you remove the polarizing filter and then mount a

3
00:00:08,720 --> 00:00:15,519
polarizing filter into a pair of glasses. Very easy to do with some 3D

4
00:00:12,719 --> 00:00:19,600
glasses. That results in a monitor that looks like it just emits white and

5
00:00:18,000 --> 00:00:24,710
nothing else. But if you're wearing the right glasses, you can actually see

6
00:00:21,039 --> 00:00:31,599
what's on screen. Let's check it out.

7
00:00:31,599 --> 00:00:38,559
Ozone Gaming Strike Battle Keyboard is a 10 keyless compact keyboard with

8
00:00:36,239 --> 00:00:42,719
multiple Cherry MX Switch variants as well as 30 macro keys with five

9
00:00:40,879 --> 00:00:46,960
profiles. Check out the link in the video description to learn more. So,

10
00:00:44,719 --> 00:00:51,120
this isn't an original Linus Tech Tips idea. This was posted by two different

11
00:00:48,800 --> 00:00:55,360
people about 2 years ago. On YouTube, it was posted by Brussup and on

12
00:00:52,879 --> 00:00:59,359
Instructables, it was posted by Deovi. And there's also two different methods

13
00:00:57,039 --> 00:01:03,280
of doing this. They both start with taking off the bezel of the monitor and

14
00:01:01,280 --> 00:01:08,720
then using a knife to cut a perimeter around the screen. It's very sketchy,

15
00:01:05,439 --> 00:01:10,960
but oh well. And then by chiseling off

16
00:01:08,720 --> 00:01:15,680
the polarizing filter, getting rid of the glue somehow with a solvent of some

17
00:01:13,119 --> 00:01:19,680
sort and then mounting a polarizing filter in a pair of glasses. Sounds

18
00:01:17,600 --> 00:01:24,159
pretty straightforward so far. The differentiating part is whether or not

19
00:01:21,520 --> 00:01:28,640
you buy some polarizing filters or reuse the polarizing filter off of your

20
00:01:25,920 --> 00:01:32,320
screen. Uh, buying them sounds like more of a sure shot. So, I made sure that I

21
00:01:30,560 --> 00:01:35,600
had some before we started this, but we're going to see which one works best

22
00:01:34,479 --> 00:01:41,600
and we're going to go through the whole process on camera. Okay, so first things

23
00:01:38,560 --> 00:01:44,240
first, I need to clear this area. I need

24
00:01:41,600 --> 00:01:47,840
to get my iixit kit ready and my screwdriver because I have to tear the

25
00:01:45,840 --> 00:01:54,720
bezel off of this guy. I'm going to remove the stand. Um, one interesting

26
00:01:51,479 --> 00:01:57,520
tidbit. Uh, I've already kind of done

27
00:01:54,720 --> 00:02:00,560
this. I used a different monitor and it super didn't work. And you might be

28
00:01:59,200 --> 00:02:04,000
wondering why I would release this video if it like super failed once already.

29
00:02:02,560 --> 00:02:08,239
The problem there was there was a pre-existing crack on the monitor. So,

30
00:02:06,719 --> 00:02:11,680
when I'm trying to pull off the polarizing filter, there's glue under

31
00:02:09,920 --> 00:02:14,959
there. The pre-existing crack spreads and I just ripped the whole thing in

32
00:02:13,120 --> 00:02:20,160
half. So, hopefully that doesn't happen again. And if not, we'll probably be

33
00:02:17,239 --> 00:02:23,840
good. Removing bezels on monitors kind of super sucks. I'm going to do

34
00:02:22,319 --> 00:02:29,200
something that's not super visually appealing and use just a flathead to pry

35
00:02:26,720 --> 00:02:34,560
it off. Realistically, you're supposed to use a spudger. Um, but I just bent

36
00:02:32,879 --> 00:02:38,800
the whole head off of one of mine because it wasn't really working properly. The problem with this guy, and

37
00:02:37,680 --> 00:02:43,280
the reason why it's going to be pretty ugly, is it's metal and it doesn't give

38
00:02:41,840 --> 00:02:48,480
at all. It might be nice if you have something plastic so it can give a little bit. I might end up messing up

39
00:02:47,040 --> 00:02:52,800
some of the plastic here. So, what I'm going to do is start on the bottom. That

40
00:02:50,959 --> 00:03:03,330
way, it's hopefully going to be the least viewed part of the

41
00:03:06,360 --> 00:03:12,239
monitor. Now, see, look at this.

42
00:03:09,599 --> 00:03:20,080
My proper prying tools don't really seem to be surviving. I just torqued the

43
00:03:15,920 --> 00:03:22,239
whole end off of that one. So, rip. I

44
00:03:20,080 --> 00:03:26,000
guess I'll go back to using my probably not going to be as pretty, but

45
00:03:23,519 --> 00:03:26,000
screwdriver

46
00:03:26,760 --> 00:03:31,360
trick. I ended up starting on the top because the bottom was giving me too

47
00:03:30,319 --> 00:03:35,599
much trouble. As you can see, the starting point is pretty rough actually.

48
00:03:33,519 --> 00:03:39,519
That's why I suggest maybe taking a little bit more time with it and using a

49
00:03:36,879 --> 00:03:44,319
more proper tool. And then from there on, it's not too bad. You'll just see

50
00:03:41,920 --> 00:03:47,840
little bumps here and there from the flathead, but it's not really the end of

51
00:03:46,239 --> 00:03:51,760
the world. I know people will care and it will bug me, so

52
00:04:00,680 --> 00:04:10,239
whatever. Okay, bezel is hopefully off. What is

53
00:04:06,720 --> 00:04:13,439
going on down here? Oh dear. There's

54
00:04:10,239 --> 00:04:14,720
some cables going to the buttons. I was

55
00:04:13,439 --> 00:04:18,400
kind of hoping that these were just going to be button plates and the actual

56
00:04:16,560 --> 00:04:22,639
button was going to be under them and not on the bezel. That is not true. As

57
00:04:20,959 --> 00:04:26,000
you can see, the whole mechanism is in here and then it goes through a wire

58
00:04:24,479 --> 00:04:32,040
into the thing. So, I'm not actually going to be able to get this out,

59
00:04:29,320 --> 00:04:34,960
which super sucks. Oh no. Yeah, I'm not going to be able to

60
00:04:34,000 --> 00:04:41,199
get it out. So, I'm going to have to get a support for it and then I'll be able to work around it. One little tidbit

61
00:04:39,360 --> 00:04:46,240
that I recommend, uh, I learned from the last monitor that your initial perimeter

62
00:04:43,600 --> 00:04:51,040
cut is actually pretty important. Um, I would recommend a sturdier, hopefully

63
00:04:48,880 --> 00:04:55,280
bit sharper knife for the actual perimeter because you want a nice clean

64
00:04:56,600 --> 00:05:02,639
cut. If that part makes it in the video, everyone's going to scream at me for

65
00:05:00,479 --> 00:05:07,520
cutting towards myself. So right now I'm just trying to connect

66
00:05:04,479 --> 00:05:09,360
the corners. So I cut four perimeter

67
00:05:07,520 --> 00:05:12,280
lines, but they don't necessarily completely match up. So I'm just trying

68
00:05:10,880 --> 00:05:18,080
to bridge them. Okay, so our perimeter lines have

69
00:05:14,880 --> 00:05:20,560
been cut. Um, we're mostly done with the

70
00:05:18,080 --> 00:05:24,720
nice big knife. Now what we need to do is try to get under those lines that we

71
00:05:22,800 --> 00:05:30,320
cut and start actually pulling up the polarizing filter. Now remember, there

72
00:05:27,039 --> 00:05:32,880
is glue under this entire thing. So,

73
00:05:30,320 --> 00:05:36,479
while you can pull it up sometimes, you do really need to chisel under there and

74
00:05:34,720 --> 00:05:42,160
separate the polarizing filter from the actual panel. So, the reason why you want a

75
00:05:39,759 --> 00:05:46,720
nice clean cut with probably a nicer knife around the perimeter is once you

76
00:05:44,240 --> 00:05:52,639
kind of get started with your chisel, as you go along the side, where you cut

77
00:05:49,440 --> 00:05:54,199
should just kind of come Oh, that part

78
00:05:52,639 --> 00:05:58,960
shouldn't go in the video. That's bad. Oh god. I was just

79
00:05:57,600 --> 00:06:03,680
commenting about how I shouldn't be cutting towards myself. So, the reason

80
00:06:01,440 --> 00:06:06,800
why you want a nice clean cut with your probably sharper knife around the

81
00:06:05,199 --> 00:06:11,120
perimeter is so that when you're moving along with the chisel, uh, the perimeter

82
00:06:09,600 --> 00:06:15,520
actually comes up. So, as you can see here, I'm pushing in and then sliding

83
00:06:13,840 --> 00:06:19,840
out, angling a little bit, pushing in again, and just moving along. And the

84
00:06:17,919 --> 00:06:24,639
perimeter should just kind of come up with my knife, which is actually quite

85
00:06:22,560 --> 00:06:27,680
helpful so that it keeps a clean edge. When you enter the first time with your

86
00:06:26,160 --> 00:06:32,080
chisel, it's probably going to be a little bit messy, but once you start

87
00:06:29,360 --> 00:06:36,560
going, everything does get easier. Another helpful trick is to not

88
00:06:34,199 --> 00:06:41,039
necessarily pull the polarizing filter all the time and kind of kind of rip it

89
00:06:38,319 --> 00:06:46,319
off, but hold it up so you can get your chisel under there more easily. Once you

90
00:06:43,280 --> 00:06:47,919
have some room like I do now, it's much

91
00:06:46,319 --> 00:06:53,199
easier to do this at the beginning. Obviously, that's not really going to

92
00:06:49,720 --> 00:06:55,039
work. So, I've I've got this whole side

93
00:06:53,199 --> 00:07:00,080
off and I've got a bit of the top and a bit of the bottom off. It starts to go a

94
00:06:57,520 --> 00:07:04,160
lot faster. Now, I will note this might not be the experience with every

95
00:07:01,520 --> 00:07:07,919
monitor. I do believe the amount of glue used on each monitor is definitely

96
00:07:06,479 --> 00:07:14,440
different, but with this one, it is going quite a bit faster. Another thing that's helping me is the clean, sharp

97
00:07:12,800 --> 00:07:19,520
cut that I got all the way around the monitor. Um, which will feel super

98
00:07:17,440 --> 00:07:24,319
sketchy while you're doing it, but is actually totally fine. So, don't worry

99
00:07:21,599 --> 00:07:30,000
about it. So, up here, it started to break a few times. Um, yeah, I don't

100
00:07:28,080 --> 00:07:33,759
really know what's going on with that. Probably something's wrong with the cut.

101
00:07:31,919 --> 00:07:37,919
I do notice there's some strand of something here. So, what I might do is

102
00:07:36,400 --> 00:07:41,599
grab the knife that I originally did the perimeter with and kind of rerun this

103
00:07:40,000 --> 00:07:44,160
area a little bit just to make sure that it's actually

104
00:07:45,880 --> 00:07:52,400
okay. So, this top bit for me is pretty

105
00:07:49,520 --> 00:07:57,280
rough. I keep getting cracks constantly going down from the top, but my bottom

106
00:07:55,199 --> 00:08:01,680
line is super clean. So, hopefully I'll have a lot of usable filter in kind of

107
00:07:59,520 --> 00:08:17,170
this area and I'll just have to ignore the top left, I guess.

108
00:08:21,080 --> 00:08:29,520
Almost. Let go. Come on. There we

109
00:08:25,560 --> 00:08:32,479
go. Okay. So, there's our polarizing

110
00:08:29,520 --> 00:08:37,039
filter. We've got uh kind of an ugly entry here where I started and then some

111
00:08:35,440 --> 00:08:41,279
big cuts up here which are pretty unfortunate. But I have a lot of usable

112
00:08:38,959 --> 00:08:45,760
space to cut out lenses to replace on here. Or there's the other method which

113
00:08:43,760 --> 00:08:49,880
I'm also going to do which is where we have purchased polarizing filters for

114
00:08:47,760 --> 00:08:55,279
like I don't know not that much off of Amazon. And we'll try each method see

115
00:08:52,640 --> 00:08:58,640
which one's better. So just a note is that this stuff on the screen isn't

116
00:08:56,880 --> 00:09:02,320
actually slashes or cuts into the screen. This is all just glue residue.

117
00:09:00,720 --> 00:09:07,040
So, I need to clean it up somehow. Hopefully, I can use isopropyl alcohol

118
00:09:04,000 --> 00:09:08,640
cuz that's all I really have on hand.

119
00:09:07,040 --> 00:09:13,880
Um, but I know people have been using gooby gone. So, we'll see what has

120
00:09:10,640 --> 00:09:13,880
happened there.

121
00:09:17,120 --> 00:09:25,600
Hey, do we have gooby gone? Do we have goooo gone? I have been using a shirt

122
00:09:23,120 --> 00:09:29,839
because the paper towel was leaving a whole bunch of crap behind and I

123
00:09:28,399 --> 00:09:34,360
wouldn't recommend that if you actually ever want to wear the shirt again. So,

124
00:09:32,160 --> 00:09:39,519
just a note. Wow. Okay. So, yeah, using a

125
00:09:37,839 --> 00:09:46,120
proper thing that is designed for removing glue probably a good idea. This

126
00:09:42,320 --> 00:09:46,120
is so much easier.

127
00:09:46,720 --> 00:09:54,320
So, one thing I would recommend is making sure that you let your whatever

128
00:09:50,959 --> 00:09:57,920
goo removal stuff you use to sit for

129
00:09:54,320 --> 00:09:59,760
probably a while and then kind of pat it

130
00:09:57,920 --> 00:10:02,640
off and take it off nicely and then do it again and let it sit and do it again

131
00:10:01,200 --> 00:10:09,279
and let it sit and just keep on doing that to the point where you can fairly

132
00:10:05,279 --> 00:10:12,240
easily just wipe the glue off. Um, I, as

133
00:10:09,279 --> 00:10:15,760
you guys saw, used the chisel blade, which was recommended on a few guides

134
00:10:14,079 --> 00:10:20,000
online saying that the blade definitely wouldn't scratch the monitor, but there

135
00:10:17,680 --> 00:10:23,760
are lines going along the monitor that you can see from just the edge of the

136
00:10:21,920 --> 00:10:28,800
knife. So, a little bit disappointed in that. And yeah, try to make sure that

137
00:10:26,279 --> 00:10:32,640
your solvent solution does more of the work than you do, and I think you'll be

138
00:10:30,320 --> 00:10:37,040
fine. We're going to call it quits there in terms of trying to touch up the

139
00:10:34,800 --> 00:10:40,959
panel. I'm going to try to get this monitor back together. I knew those

140
00:10:39,440 --> 00:10:45,360
wires were going to be a problem. All right. One thing again to take note of

141
00:10:43,680 --> 00:10:50,959
is you can do this with pretty much whatever panel you want, but I recommend

142
00:10:48,240 --> 00:10:56,480
going my route and buying some kind of cheap panel off some dude who's moving

143
00:10:53,120 --> 00:10:58,399
on Craigslist um because it's not a

144
00:10:56,480 --> 00:11:03,200
perfect method. But we'll talk about that more later on. Now, what we need to

145
00:11:01,040 --> 00:11:07,360
do is plug this guy in. Make sure it's all white, which I'm sure it will be.

146
00:11:05,040 --> 00:11:11,519
And then check out the alignment for these filters so I can cut them into

147
00:11:09,519 --> 00:11:18,640
some glasses. Can you even see that, Brandon? See what do you want to plug

148
00:11:14,880 --> 00:11:20,720
the Wancho computer in?

149
00:11:18,640 --> 00:11:25,519
I actually think it might be a better approach at this point. I'm just doing

150
00:11:22,560 --> 00:11:29,200
Okay, so it works. Um, a kind of frustrating thing happened while we were

151
00:11:27,200 --> 00:11:32,560
going though. Nothing went wrong with the actual removal of the polarizing

152
00:11:30,880 --> 00:11:38,959
filter or anything, but it seems like the inverter on the monitor

153
00:11:35,079 --> 00:11:41,959
has died at some point in time. So, if I

154
00:11:38,959 --> 00:11:46,000
shove this guy on here and change the

155
00:11:41,959 --> 00:11:49,839
source, you'll see it works, but then

156
00:11:46,000 --> 00:11:50,959
goes away almost immediately. So, we're

157
00:11:49,839 --> 00:11:56,480
going to go through the rest of it. I'm going to make some glasses. I'm going to test some things, but pretty

158
00:11:54,079 --> 00:12:00,959
disappointed that the monitor died. So, I'm going to have to kind of rotate

159
00:11:58,079 --> 00:12:06,240
trying to turn this thing on and then try to figure out what orientation these

160
00:12:02,800 --> 00:12:06,240
things need to go before I cut

161
00:12:09,320 --> 00:12:14,240
them. Oh, that's really close.

162
00:12:14,279 --> 00:12:19,839
Yeah. Yeah, that's good. So, now I know

163
00:12:17,760 --> 00:12:24,959
from just not letting go of it that this part needs to be going up. Use my lens

164
00:12:22,320 --> 00:12:30,240
that I popped out of my glasses earlier. um squish that kind of against the

165
00:12:27,920 --> 00:12:37,480
polarizing filter and I'm going to use a thin Sharpie to outline it. And then I'm

166
00:12:33,760 --> 00:12:41,360
just going to cut on the inside of the

167
00:12:37,480 --> 00:12:44,240
outline and then it should work. Okay,

168
00:12:41,360 --> 00:12:48,000
so I've cut my filter. Now it's time to actually fit it into my pair of

169
00:12:50,040 --> 00:12:55,920
glasses. I think that works so far. Feel like a hipster not having one of my

170
00:12:53,920 --> 00:13:01,720
lenses there. But now I just need to fit one more of them and I think we'll be

171
00:13:01,720 --> 00:13:06,959
good. All right, so my glasses are set

172
00:13:05,120 --> 00:13:09,279
up and ready to go. Let's see if they actually

173
00:13:13,800 --> 00:13:20,399
work. There we

174
00:13:17,079 --> 00:13:22,639
go. All right, so the glasses do work.

175
00:13:20,399 --> 00:13:25,360
Um, sorry that the inverter is borked so you can't really see it all that well.

176
00:13:24,399 --> 00:13:30,279
But something I'm going to do is actually pass these to Brandon and then

177
00:13:27,920 --> 00:13:34,639
hold those over the lens. We're going to do this live and

178
00:13:32,880 --> 00:13:38,480
then I'm going to change the source and hopefully you guys will be able to see

179
00:13:36,000 --> 00:13:42,720
it better with that over the lens. Give me a moment. I'm going to have no idea

180
00:13:41,279 --> 00:13:52,480
when this works because I'm not actually going to be able to see it. Is that good? Okay, there we go.

181
00:13:47,639 --> 00:13:54,720
So, the project worked. The monitor

182
00:13:52,480 --> 00:13:59,680
didn't, but the inverter dying had nothing to do with what we did for the

183
00:13:56,160 --> 00:14:02,160
project. So, poor old like 10year-old

184
00:13:59,680 --> 00:14:10,000
Flatron is is going to have to be retired and recycled after this. But, oh

185
00:14:06,120 --> 00:14:12,399
well. I would still recommend getting an

186
00:14:10,000 --> 00:14:16,880
old monitor. I just wouldn't necessarily recommend getting a very old monitor or

187
00:14:15,199 --> 00:14:21,760
one that you don't trust. I bought this one off Craigslist for 30 bucks or

188
00:14:19,360 --> 00:14:26,240
something. And I only tested it for about 2 minutes 2 weeks ago and now fast

189
00:14:24,399 --> 00:14:30,639
forward two weeks, the inverter's dead. Things are

190
00:14:28,199 --> 00:14:34,240
bad. Another little bit that I have to say is while being able to remove the

191
00:14:32,560 --> 00:14:38,959
polarizing filter that was on the monitor and using it again is cool, you

192
00:14:37,120 --> 00:14:43,360
also need to remove the anti-glare filter off of here. And while it's

193
00:14:40,639 --> 00:14:47,920
possible by soaking it in hot water and then trying to peel it off like a

194
00:14:44,639 --> 00:14:50,000
sticker and stuff, it's really annoying.

195
00:14:47,920 --> 00:14:55,199
And the polarizing filters from Amazon are super cheap and work really well.

196
00:14:53,040 --> 00:14:58,480
Uh, one thing to note on here is that they also have a film on it, a

197
00:14:56,959 --> 00:15:03,120
sticker-like substance, which is just supposed to protect them, but it's super

198
00:15:00,399 --> 00:15:06,639
easy to take off. So, not nearly the same problem that we have with the

199
00:15:04,079 --> 00:15:11,040
anti-glare filter. Another thing is the goof off or gooby gone or whatever the

200
00:15:08,880 --> 00:15:14,720
heck paint thinner you end up using to remove your glue. Let it sit on there

201
00:15:12,800 --> 00:15:19,199
for a while. Dry it off. Let it sit again. Dry it off. Let it sit again. Do

202
00:15:16,800 --> 00:15:22,320
that a few times so that you don't have to scrape the glue off. It should come

203
00:15:20,800 --> 00:15:27,120
off much more evenly and you'll have a better time. I probably should have done

204
00:15:24,240 --> 00:15:31,279
that. But honestly, it wasn't that hard. It was sketchy. It feels very weird

205
00:15:29,279 --> 00:15:35,760
bringing a knife to a monitor screen. It doesn't feel natural. Um, but yeah, if

206
00:15:34,560 --> 00:15:40,959
you guys do it, please post it on the forum. I'd like to see your projects.

207
00:15:38,240 --> 00:15:46,959
Mac Welden gear ranging from underwear to undershirts, t-shirts, socks, sweats,

208
00:15:44,959 --> 00:15:51,199
and they're really easy to order, and honestly, they're really easy to wear,

209
00:15:48,720 --> 00:15:55,440
too. I mean, their boxers are literally cradling my man parts as we speak, and

210
00:15:53,680 --> 00:15:59,759
they do a great job of it. Something that's pretty great is that their

211
00:15:56,880 --> 00:16:05,680
products are naturally antimicro reel, but especially the Puma cotton with

212
00:16:02,399 --> 00:16:07,440
silver XT2 ones. So, I swear to my

213
00:16:05,680 --> 00:16:11,920
girlfriend, if you're watching this, these were clean before I put them on.

214
00:16:09,680 --> 00:16:15,440
But you in the audience should run an experiment where you get the silver ones

215
00:16:13,519 --> 00:16:21,199
and see how long you can wear them until they, you know, like actually smell for

216
00:16:18,480 --> 00:16:26,639
science. Anyways, by the way, if you hit up the macweldon.com website and use the

217
00:16:23,680 --> 00:16:29,320

know. Check it out. Thanks for watching, guys. If you
