1
00:00:02,760 --> 00:00:05,760
oh

2
00:00:06,080 --> 00:00:11,460
hi I'm Linus Sebastian and you may

3
00:00:09,120 --> 00:00:17,340
remember me professing my love for LG's OLED displays in YouTube videos like

4
00:00:13,799 --> 00:00:20,640
every other monitor is dead to me and my

5
00:00:17,340 --> 00:00:22,619
endgame gaming TV well now that I've

6
00:00:20,640 --> 00:00:28,920
been daily driving one for the past few months I'm going to show you everything

7
00:00:25,100 --> 00:00:30,930
wrong with it and hopefully how to fix

8
00:00:28,920 --> 00:00:32,420
it what about

9
00:00:32,420 --> 00:00:37,559
thanks Jamie but you know I would never

10
00:00:35,700 --> 00:00:43,020
forget to tell our viewers about our sponsor glasswire instantly see your

11
00:00:40,440 --> 00:00:48,239
past and current network activity detect malware and block badly behaving apps on

12
00:00:45,480 --> 00:00:54,860
your PC or Android device with glassware use offer code Linus and get 25 off at

13
00:00:52,079 --> 00:00:54,860
the link below

14
00:01:01,860 --> 00:01:10,320
when I reviewed the 48 inch LG C10 earlier this year I loved it so much

15
00:01:07,680 --> 00:01:15,840
that as soon as David got his own and returned mine I dumped my old monitor

16
00:01:12,479 --> 00:01:17,520
setup and put it in my office and all of

17
00:01:15,840 --> 00:01:21,840
the great stuff I said about it still holds up it's high refresh rate and

18
00:01:19,860 --> 00:01:26,040
unbeatable pixel response times make it among the best gaming displays on the

19
00:01:23,520 --> 00:01:29,759
market and it's Inky blacks and great color performance make it super

20
00:01:27,600 --> 00:01:34,860
comfortable to use for everything else be it movies spreadsheets the wipes

21
00:01:32,939 --> 00:01:39,240
that is why I'm still gonna have an affiliate link to it below but before

22
00:01:37,320 --> 00:01:46,500
you click on that this burn-in is a result of snapping my

23
00:01:43,799 --> 00:01:52,079
Windows into the four corners of my display a pretty common thing to do on

24
00:01:49,320 --> 00:01:56,700
such a large Monitor and Wendell from level one Tex who has been daily driving

25
00:01:53,820 --> 00:02:01,439
one of these for longer than me has also hit some snags

26
00:01:58,560 --> 00:02:05,360
it is amazing but what's not amazing is that I'm starting to see signs of burn

27
00:02:03,299 --> 00:02:11,099
in it's unsettling it's just enough to be

28
00:02:07,920 --> 00:02:14,340
unsettling yeah mine too

29
00:02:11,099 --> 00:02:16,440
but LG thought of that and maybe just

30
00:02:14,340 --> 00:02:20,700
maybe we can fix this with the feature that's built into every OLED display

31
00:02:17,940 --> 00:02:25,860
that I'm aware of but LG calls pixel Refresher

32
00:02:21,959 --> 00:02:27,840
start now hopefully that works I guess

33
00:02:25,860 --> 00:02:32,760
we'll find out soon enough but while it's running let's talk about

34
00:02:30,660 --> 00:02:36,720
burning a little more because there's a lot of mixed messages out there

35
00:02:34,020 --> 00:02:40,920
including from us on the one hand you've got manufacturers like LG saying it's

36
00:02:39,120 --> 00:02:45,420
not a problem and on the other hand you've got Tech experts like Wendell

37
00:02:43,080 --> 00:02:50,160
saying I would say that with heavy use you know six eight ten hours a day you

38
00:02:48,959 --> 00:02:56,940
can only count on these things lasting about a year maybe two what's the truth

39
00:02:53,580 --> 00:02:58,860
as usual it's somewhere in between but

40
00:02:56,940 --> 00:03:03,959
to understand why we need a bit of background to start with the term

41
00:03:00,840 --> 00:03:05,700
burn-in is a relic of the CRT days when

42
00:03:03,959 --> 00:03:10,980
your monitor was as big as a microwave and your TV was the size of an oven

43
00:03:08,760 --> 00:03:16,400
it's also a total mischaracterization of the problem because burn-in refers to

44
00:03:13,620 --> 00:03:21,840
ghost images that were quite literally burned into the luminescent phosphor

45
00:03:19,680 --> 00:03:26,280
coating on the back of the glass of those older style displays here's an

46
00:03:24,060 --> 00:03:30,780
example that is so extreme that the DMV stopped having to even turn the TV on

47
00:03:28,140 --> 00:03:35,040
anymore but we continue to use this term because even though the mechanisms are

48
00:03:33,000 --> 00:03:40,799
different the behavior of modern displays can be very similar so whether

49
00:03:37,680 --> 00:03:43,860
you're talking about a CRT LCD plasma or

50
00:03:40,799 --> 00:03:46,260
an OLED if you display static or

51
00:03:43,860 --> 00:03:51,780
non-moving images for extended periods of time you might eventually see them as

52
00:03:48,720 --> 00:03:54,900
ghosts that haunt your other content

53
00:03:51,780 --> 00:03:57,299
so this type of image retention can

54
00:03:54,900 --> 00:04:03,299
affect nearly all direct view modern displays the only difference is How

55
00:04:00,180 --> 00:04:05,459
likely you are to encounter it for LCDs

56
00:04:03,299 --> 00:04:10,019
which make up the majority of TVs and monitors today we could more accurately

57
00:04:07,739 --> 00:04:14,340
describe this phenomenon as image retention because it's typically caused

58
00:04:12,120 --> 00:04:18,900
by the liquid crystals losing their ability to easily return to a relaxed

59
00:04:16,500 --> 00:04:23,160
State we don't talk about it much though because it's pretty uncommon unlike

60
00:04:21,060 --> 00:04:27,600
lttstore.com we talk about that all the time look at this great desk PAD as for

61
00:04:25,139 --> 00:04:34,979
oleds each pixel of an OLED display actually each RGB subpixel is an

62
00:04:31,860 --> 00:04:36,840
individual light source and like LCDs

63
00:04:34,979 --> 00:04:41,460
they're controlled by thin film transistors that can get stuck on which

64
00:04:39,960 --> 00:04:46,440
is why the retention on my screen appears as a bright spot rather than a

65
00:04:44,160 --> 00:04:51,240
dark spot the thing is that this can happen way sooner than on an LCD since

66
00:04:49,199 --> 00:04:57,120
Illuminating a subpixel takes More Voltage and that's not all the O and

67
00:04:54,300 --> 00:05:02,759
OLED means that each subpixel is organic and from the moment it turns on it is

68
00:04:59,580 --> 00:05:04,919
deteriorating and the brighter each one

69
00:05:02,759 --> 00:05:08,639
of those little candles burns the faster it will dim

70
00:05:06,180 --> 00:05:12,660
now obviously this gradual weakening isn't going to be too noticeable if

71
00:05:10,440 --> 00:05:18,060
every pixel gets used exactly the same but How likely is that to happen in the

72
00:05:15,360 --> 00:05:22,259
real world so to combat this educated OLED users can employ a number of tricks

73
00:05:20,400 --> 00:05:25,740
to extend their lifespan I've been running this monitor super

74
00:05:23,759 --> 00:05:31,440
conservatively my OLED brightness has only been around 60. I left on the uh

75
00:05:29,699 --> 00:05:34,860
you know the logo compensation thing where it tries to detect a logo or you

76
00:05:33,720 --> 00:05:40,320
know like the start menu and it's like oh let me move that around a little bit those are some good tips lowering the

77
00:05:38,280 --> 00:05:45,600
brightness overall means that each pixel isn't blasting out as much light wearing

78
00:05:42,660 --> 00:05:50,520
itself out logo compensation tries to surgically dim static elements on the

79
00:05:47,940 --> 00:05:55,740
screen like sports score bugs or news channel logos and Screen shift or pixel

80
00:05:53,580 --> 00:06:00,660
shift takes the whole on-screen image and tries to kind of move it around by a

81
00:05:58,560 --> 00:06:05,400
few pixels every so often in hopes of at least softening the transitions between

82
00:06:02,759 --> 00:06:10,320
the more burned out pixels and the less burned at once but as you saw when we

83
00:06:07,740 --> 00:06:14,759
began this video even a few months of use was enough for me to overcome all of

84
00:06:12,660 --> 00:06:20,220
those protections my brightness by the way was usually set to 80 and I also

85
00:06:17,699 --> 00:06:24,979
have pixel shift and Logo compensation enabled let's take a look at our results

86
00:06:22,440 --> 00:06:24,979
shall we

87
00:06:26,280 --> 00:06:33,120
wow okay hold on

88
00:06:31,080 --> 00:06:39,000
yes yes a lot better but this kind of thing

89
00:06:35,940 --> 00:06:40,919
doesn't work forever the pixel refresh

90
00:06:39,000 --> 00:06:44,759
function of the display does help when you turn it off it's supposed to

91
00:06:42,240 --> 00:06:48,720
automatically do that on its own but I think it's kind of diminishing returns

92
00:06:46,020 --> 00:06:53,520
at this point text in in certain areas are not quite as sharp as it used to be

93
00:06:50,880 --> 00:06:56,940
and uh I've got this sort of weird red splotch in the middle of the screen

94
00:06:55,080 --> 00:07:03,960
because you know so much stuff is going on in the middle of the screen great

95
00:07:00,539 --> 00:07:05,699
and even if pixel refresher works

96
00:07:03,960 --> 00:07:09,840
perfectly for you there are some daily use problems with these TVs that we

97
00:07:07,800 --> 00:07:14,160
should have caught in our review one inconvenience is that they don't handle

98
00:07:11,940 --> 00:07:18,360
Auto Wake from sleep the way that a monitor does so you'll have to manually

99
00:07:16,319 --> 00:07:22,199
turn it on every time you sit down at your computer but that one's pretty

100
00:07:19,919 --> 00:07:25,500
minor compared to the auto dimming issues that Barnacles has been

101
00:07:24,180 --> 00:07:30,419
struggling with now I understand why LG is doing this

102
00:07:28,199 --> 00:07:35,699
remember the whole burn-in thing but when you've got three displays all side

103
00:07:33,000 --> 00:07:40,680
by side by side something as simple as dragging a window across a border can

104
00:07:37,560 --> 00:07:43,020
cause one or more of the TVs to suddenly

105
00:07:40,680 --> 00:07:48,539
change their brightness from I think I can see it to eye searing

106
00:07:45,960 --> 00:07:54,120
now I on the other hand am only running one 48 inch display and I only have to

107
00:07:51,660 --> 00:07:58,680
do my little brightness dance when I'm reading or editing a large document for

108
00:07:56,400 --> 00:08:03,240
an extended period of time so given that burn-in is a much larger concern for me

109
00:08:01,199 --> 00:08:07,919
I'm content to leave the auto dimming alone but if you absolutely cannot

110
00:08:05,220 --> 00:08:15,720
tolerate it there does appear to be a fix and there it is

111
00:08:11,340 --> 00:08:17,460
that's right we've got it this is the LG

112
00:08:15,720 --> 00:08:22,680
service technician remote that can supposedly access menus that are hidden

113
00:08:20,039 --> 00:08:27,960
using the regular consumer one allploof said was play with it

114
00:08:24,479 --> 00:08:30,300
shall we okay well I mean key okay you

115
00:08:27,960 --> 00:08:33,979
can do just regular stuff like change in input it's a p-check

116
00:08:36,000 --> 00:08:41,099
oh crap well now what man how much do I

117
00:08:39,120 --> 00:08:45,600
miss having buttons like this instead of just having an input button that you

118
00:08:42,599 --> 00:08:46,820
have to click a bunch of times just HDMI

119
00:08:45,600 --> 00:08:52,740
too HDMI one dedicated buttons

120
00:08:50,399 --> 00:08:57,839
I kind of just want this remote to just be this remote

121
00:08:54,240 --> 00:09:00,300
okay can I UNP check it

122
00:08:57,839 --> 00:09:04,680
sound check oh picture check picture check and sound check that's what it is

123
00:09:02,040 --> 00:09:07,700
man there's so many buttons on here what's P only

124
00:09:10,100 --> 00:09:17,100
LG service remote password Here We Go

125
00:09:14,580 --> 00:09:23,220
voice according to Reddit it's a zero four one three what's so special about

126
00:09:20,339 --> 00:09:29,339
that date LG and look how smart this is see the IR emitter is uh angled such

127
00:09:27,660 --> 00:09:32,700
that it'll just work if you're just like holding it like this and looking at it

128
00:09:30,899 --> 00:09:37,680
that's awesome menu

129
00:09:34,560 --> 00:09:39,600
oh hello this all looks like the regular

130
00:09:37,680 --> 00:09:47,399
menu whoa hi in tart whoa and then we want

131
00:09:42,660 --> 00:09:50,700
OLED TPC enable off

132
00:09:47,399 --> 00:09:52,620
wow hi

133
00:09:50,700 --> 00:09:58,620
oh look at that HDR on off just like that I guess normal

134
00:09:56,040 --> 00:10:03,660
is auto man this is the kind of thing you could really get into the weeds

135
00:10:00,779 --> 00:10:07,260
tuning and by the way it would void the heck out of your warranty so if you ever

136
00:10:05,399 --> 00:10:11,160
did need to get any kind of servicing done or even update the firmware on your

137
00:10:09,300 --> 00:10:16,500
TV it is strongly recommended that you return all of the service menu options

138
00:10:13,380 --> 00:10:18,300
to normal and then do it otherwise I

139
00:10:16,500 --> 00:10:23,600
take no responsibility for your stuff breaking all right

140
00:10:20,399 --> 00:10:23,600
and we're back

141
00:10:24,420 --> 00:10:30,120
is this is this brighter than before

142
00:10:27,420 --> 00:10:34,380
this looks terrible just a sec Houston we definitely have a problem over in

143
00:10:32,940 --> 00:10:39,899
Vivid mode and what I wonder if that's why it looks like crap this still

144
00:10:36,120 --> 00:10:44,339
doesn't look quite right it's horrible

145
00:10:39,899 --> 00:10:48,480
and then the second I change this to HDR

146
00:10:44,339 --> 00:10:51,779
I bet it's fixed yep and perfect now

147
00:10:48,480 --> 00:10:55,019
I am going to plug it into my laptop

148
00:10:51,779 --> 00:10:57,240
real quick come on

149
00:10:55,019 --> 00:11:01,200
still looks like absolute dog crap it's doing something to the incoming signal I

150
00:10:59,040 --> 00:11:08,579
have no idea what we're gonna put this all back to default exit okay now we are

151
00:11:05,940 --> 00:11:12,779
going to do a factory reset I think I found it I think I found it I think it

152
00:11:10,140 --> 00:11:16,200
was just super resolution see I thought that was off but I wonder if it's just

153
00:11:14,399 --> 00:11:21,019
like a stupid thing where it was turned on then turned off because we are

154
00:11:18,899 --> 00:11:26,760
in SDR right now and this looks fine

155
00:11:24,320 --> 00:11:31,680
all right good it's back to normal factory reset and then

156
00:11:29,700 --> 00:11:35,640
changing settings even though the changing them back doesn't break it

157
00:11:33,660 --> 00:11:41,519
again seems fine we need to move on because none of what we've talked about

158
00:11:38,220 --> 00:11:43,560
so far supports LG's position that burn

159
00:11:41,519 --> 00:11:49,920
in is not a problem let's talk about that the thing is the

160
00:11:47,100 --> 00:11:55,320
oleds on my desks are not the only ones in my life and the 77 inch G10 in my

161
00:11:53,220 --> 00:11:59,880
living room has actually been there for about as long as Wendell has been daily

162
00:11:57,000 --> 00:12:05,279
driving his C10 and in spite of being used daily for not just movies but also

163
00:12:02,880 --> 00:12:11,399
games which are notorious for burning in static elements like speedometers life

164
00:12:07,860 --> 00:12:13,680
bars you get the point it shows no signs

165
00:12:11,399 --> 00:12:18,420
of burn-in whatsoever and you'll actually find plenty of similar

166
00:12:15,420 --> 00:12:21,300
testimonials from users online so it's

167
00:12:18,420 --> 00:12:27,120
clear that oleds absolutely can live long healthy lives doing what they do

168
00:12:24,360 --> 00:12:33,060
best absolutely crushing other Technologies with their image quality

169
00:12:29,459 --> 00:12:35,640
they just clearly require a level of TLC

170
00:12:33,060 --> 00:12:40,920
that other display Technologies do not which means as much as I agree with

the channel I'm also gonna have to be more careful about my display

177
00:12:58,139 --> 00:13:04,320
recommendations going forward because even though by the way the service menu

178
00:13:02,220 --> 00:13:10,019
thing does appear to have worked these TVs are clearly best suited for

179
00:13:07,079 --> 00:13:15,300
customers with more typical home theater use cases and they are only suitable as

180
00:13:13,019 --> 00:13:20,820
monitors for deep pocketed enthusiasts who are willing to accept either the

181
00:13:17,940 --> 00:13:26,519
downsides like the auto dimming or the cost of replacing them ever so often

182
00:13:24,779 --> 00:13:30,300
