1
00:00:00,000 --> 00:00:07,279
could we kill the filming lights for just a short period so i can try it out

2
00:00:04,080 --> 00:00:09,280
dang there's nothing quite like a giant

3
00:00:07,279 --> 00:00:14,880
projector screen is there this doesn't look like very gamery packaging

4
00:00:11,840 --> 00:00:18,080
but with a lightning fast 240hz refresh

5
00:00:14,880 --> 00:00:19,760
rate 15.7 milliseconds of input lag and

6
00:00:18,080 --> 00:00:25,359
HDR support with up to a 120 inch screen this

7
00:00:22,720 --> 00:00:31,039
projector sounds too good to be true but optimus says it is true they claim that

8
00:00:27,840 --> 00:00:34,079
their uhd30 is designed from the ground

9
00:00:31,039 --> 00:00:36,480
up for all gaming and delivers an

10
00:00:34,079 --> 00:00:41,040
unmatched gaming experience but can it possibly get even close to what you

11
00:00:38,960 --> 00:00:46,399
would experience from a tv or even just a really big monitor can you actually

12
00:00:42,960 --> 00:00:49,680
get a convincing HDR gaming experience

13
00:00:46,399 --> 00:00:52,879
from a 1300 dlp projector what corners

14
00:00:49,680 --> 00:00:55,120
had to be cut to manage a 240 hertz

15
00:00:52,879 --> 00:01:00,640
refresh rate is this gonna turn into one of those like nonsense debunking

16
00:00:58,160 --> 00:01:04,320
manufacturer say videos why hasn't Linus told us about the

17
00:01:02,079 --> 00:01:08,880
sponsor yet soundcore has released its latest wireless earbuds the liberty air

18
00:01:06,320 --> 00:01:12,880
2 pros they feature clear audio and multi-mode active noise cancellation

19
00:01:11,040 --> 00:01:16,400
learn more at the end of the video or at the link in the video description

20
00:01:23,439 --> 00:01:30,640
the uhd30 isn't the first gaming focused projector and in fact it's not even the

21
00:01:27,920 --> 00:01:34,960
only 240hz model on the market it just happens to be the only one that's priced

22
00:01:32,560 --> 00:01:40,240
within reach of consumers and compared to past gaming projectors that focused

23
00:01:37,759 --> 00:01:46,000
on the stereoscopic 3d experience the uhd30s list of specs is more relevant to

24
00:01:43,600 --> 00:01:48,920
today's discerning gamer including the standout features we want to investigate

25
00:01:47,759 --> 00:01:55,600
today 240hz refresh rate at 1080p and

26
00:01:51,920 --> 00:01:57,759
acclaimed 15.7 milliseconds of input lag

27
00:01:55,600 --> 00:02:02,320
now obviously neither of these numbers are on par with the best gaming monitors

28
00:02:00,079 --> 00:02:10,160
today but in the projector world where it's common to see 80 milliseconds of

29
00:02:04,560 --> 00:02:10,160
lag this is a potential game changer

30
00:02:11,760 --> 00:02:19,040
get it optima claims this unit can project an image up to 300 inches

31
00:02:16,640 --> 00:02:23,520
diagonally but you're gonna start losing brightness and contrast pretty hardcore

32
00:02:22,239 --> 00:02:28,239
not to mention that you would need an absolutely massive room for that to make

33
00:02:25,920 --> 00:02:35,120
any sense whatsoever i mean the image alone would be over 12 feet tall and 22

34
00:02:32,160 --> 00:02:39,599
feet wide also this is not a short throw projector so

35
00:02:36,879 --> 00:02:44,560
we settled on a 100 inch image which already requires at least 11 feet

36
00:02:42,640 --> 00:02:51,840
between the projector lens and the surface of our screen we wanted to go

37
00:02:46,560 --> 00:02:51,840
300 inches we need to back it right up

38
00:02:51,920 --> 00:02:58,319
oh now it's time for some gaming and before you say it yes we know a 12 foot roll of

39
00:02:56,800 --> 00:03:01,760
seamless white paper isn't going to give us the best performance but it'll be

40
00:03:00,400 --> 00:03:05,840
better than the painted walls that we have here so for a real setup you should

41
00:03:04,080 --> 00:03:09,840
always leave him in your budget for a proper screen

42
00:03:07,440 --> 00:03:12,959
hey wait a minute what is this nicholas

43
00:03:10,959 --> 00:03:18,959
you couldn't be arsed to fix the trapezoid shape of the image the problem

44
00:03:15,680 --> 00:03:21,519
is nicholas did notice this problem and

45
00:03:18,959 --> 00:03:25,360
did try to fix it it's optima who didn't feel that it was worth mentioning on the

46
00:03:23,599 --> 00:03:28,959
product page let's play around with the settings of it shall we oh enhanced

47
00:03:27,280 --> 00:03:33,920
gaming well we definitely want enhanced gaming don't we the enhanced gaming mode

48
00:03:30,959 --> 00:03:39,040
dramatically lowers the input leg but it does come at a cost once you've enabled

49
00:03:36,239 --> 00:03:43,120
it you can see here that our image is in fact square now

50
00:03:40,720 --> 00:03:47,360
but that's only because our projector happens to be sitting in exactly the

51
00:03:45,040 --> 00:03:53,440
right position when you turn on enhanced gaming which you need for that low input

52
00:03:49,760 --> 00:03:56,000
leg keystone adjustments cannot be made

53
00:03:53,440 --> 00:04:00,959
so if we wanted to mount our projector up by the ceiling and have our screen

54
00:03:58,400 --> 00:04:06,000
down closer to our couch level we would simply not be able to do that without

55
00:04:03,360 --> 00:04:09,680
experiencing some kind of distortion of the image it's probably worth mentioning

56
00:04:07,840 --> 00:04:14,400
that if you don't care about input lag it does have 40 degrees of keystone

57
00:04:11,760 --> 00:04:20,400
correction but it's vertical only not horizontal so then i'm gonna grab this

58
00:04:16,840 --> 00:04:21,519
lttstore.com CPU pillow

59
00:04:20,400 --> 00:04:27,040
oh yeah get comfortable and assume that i am

60
00:04:24,160 --> 00:04:31,199
some kind of genius whiz kid projector mounting master and that we can get it

61
00:04:29,280 --> 00:04:34,639
configured right without relying on keystone and actually play some freaking

62
00:04:33,199 --> 00:04:40,960
games i thought maybe we were plugged into the HDMI 1.4 port so only one of them is

63
00:04:38,720 --> 00:04:46,080
HDMI 2.0 which you'll need for 240hz 1080p after a little bit of tinkering

64
00:04:43,120 --> 00:04:50,240
we've got it running at 1080p 240hz with HDR turns out there's a bit of weirdness

65
00:04:48,479 --> 00:04:54,160
where games will think that the projector's default resolution is

66
00:04:52,160 --> 00:05:00,800
1920x1200 which is not supported at 240 hertz so

67
00:04:57,280 --> 00:05:00,800
it can get a little confused

68
00:05:01,199 --> 00:05:08,800
that feels pretty darn responsive and HDR makes a big difference on a

69
00:05:06,240 --> 00:05:12,560
projector actually i'm pretty impressed by how black

70
00:05:10,479 --> 00:05:15,280
black is around the edges like a lot of the time you can end up with black

71
00:05:13,759 --> 00:05:20,880
looking just kind of gray because there's not enough contrast overall this

72
00:05:17,360 --> 00:05:23,680
game is a little dark right now for me

73
00:05:20,880 --> 00:05:28,639
though wow that really does feel pretty darn good i'm definitely noticing

74
00:05:26,400 --> 00:05:34,000
though that at a comfortable distance for the size of this image i am seated

75
00:05:31,680 --> 00:05:38,400
right next to the freaking projector which has kind of an annoying fan in it

76
00:05:36,639 --> 00:05:42,560
and also i'm not able to sit dead center in front of

77
00:05:40,080 --> 00:05:45,840
the screen because i would block it not having any keystone adjustment

78
00:05:44,000 --> 00:05:49,280
definitely an oversight but i can't fault the responsiveness

79
00:05:47,520 --> 00:05:54,000
like that feels really good and you know what i don't even notice any rainbow effect

80
00:05:52,639 --> 00:05:57,840
for those who aren't familiar the rainbow effect is a phenomenon where as

81
00:05:56,240 --> 00:06:01,759
your eyes move around to look at different parts of the image or as

82
00:05:59,680 --> 00:06:07,199
objects move around on the screen you can see a kind of weird

83
00:06:03,680 --> 00:06:09,440
rainbowy fringing at the edges that is

84
00:06:07,199 --> 00:06:14,160
can be quite distracting for some people and impossible to notice for others i'm

85
00:06:12,160 --> 00:06:19,520
reasonably sensitive to it and what it basically means if we don't see it here

86
00:06:16,400 --> 00:06:21,120
is that the mirrors are moving so fast

87
00:06:19,520 --> 00:06:25,600
that they're able to go all the way from one state to another without seeing

88
00:06:23,280 --> 00:06:29,919
those weird artifacts in between while we were switching over to 60hz 4k we

89
00:06:27,680 --> 00:06:36,560
noticed another interesting disadvantage of gaming mode 4k looks like absolute

90
00:06:33,120 --> 00:06:38,560
dog crab text looks i would describe as

91
00:06:36,560 --> 00:06:44,000
pretty all right we turn enhanced gaming mode on and honestly it looks as bad as

92
00:06:41,360 --> 00:06:46,560
1080p or maybe even a little worse than what i would expect

93
00:06:45,440 --> 00:06:52,800
you see that it's pretty i don't know it's pretty bad this isn't the kind of thing that i

94
00:06:49,600 --> 00:06:54,960
would notice in game but on the desktop

95
00:06:52,800 --> 00:06:58,720
it's pretty jarring like here like these these hanging objects here normally if

96
00:06:57,120 --> 00:07:02,720
we were at 1080p i would i would definitely see stair stepping and

97
00:07:00,720 --> 00:07:06,240
aliasing on them but it's like i don't know it's like 4k but

98
00:07:04,560 --> 00:07:10,400
like here let's bring up some text again i mean yeah this text looks fine but

99
00:07:08,319 --> 00:07:14,639
it's really really big text yeah no see this looks crappy weird huh could we

100
00:07:12,800 --> 00:07:17,919
kill the filming lights for just a short period so i can try it out

101
00:07:16,880 --> 00:07:22,720
dang this looks freaking awesome now i could

102
00:07:20,639 --> 00:07:25,840
get used to this and in terms of input lag

103
00:07:23,680 --> 00:07:29,440
not bad we're only running at 60 hertz now though like it's clearly not up

104
00:07:27,759 --> 00:07:34,720
there with the best gaming monitors but it's it's fine there's nothing quite

105
00:07:32,160 --> 00:07:38,960
like a giant projector screen is there now that we've experienced it let's talk

106
00:07:36,479 --> 00:07:44,319
about how this even works how is optima getting 240 hertz out of a projector how

107
00:07:41,759 --> 00:07:49,520
do dlp projectors even work well at the core of every dlp projector there's a

108
00:07:47,120 --> 00:07:54,400
lamp module and the light output is then passed through a spinning color wheel in

109
00:07:51,520 --> 00:08:00,400
this case it's an eight segment rgbw rgbw wheel this creates a rapid

110
00:07:57,680 --> 00:08:04,319
repeating sequence of red green blue white red green blue white light

111
00:08:02,720 --> 00:08:07,680
speaking of RGB and projectors by the way we have a video with a sweet laser

112
00:08:06,479 --> 00:08:14,240
projector that we're going to be trying out be sure you're subscribed for that just for some clarity the white cell is

113
00:08:11,919 --> 00:08:18,400
actually just clear this allows for a brighter overall picture the light

114
00:08:16,160 --> 00:08:23,599
sequence is then reflected off of the digital micro mirror device or dmd

115
00:08:21,199 --> 00:08:28,319
through the lens and then onto a background of your choice the dmd chip

116
00:08:25,919 --> 00:08:32,399
in the uhd30 has an array of mirrors that sit on a hinge with each mirror

117
00:08:30,160 --> 00:08:36,000
being a pixel and the mirrors arranged in a

118
00:08:33,240 --> 00:08:40,959
1920x1080 grid these mirrors are digitally controlled switching on and

119
00:08:38,159 --> 00:08:44,080
off in around one microsecond flipping them from either reflecting light

120
00:08:42,640 --> 00:08:49,040
through the lens or reflecting light away from the lens

121
00:08:47,200 --> 00:08:54,959
for reference by the way a single frame at 240hz is about 4100 microseconds so

122
00:08:52,720 --> 00:09:01,040
these things are moving real fast to get a 4k picture the dmd panel itself is

123
00:08:58,399 --> 00:09:06,959
actually shifted physically four times per frame so you're literally creating

124
00:09:03,600 --> 00:09:08,800
four entire 1080p frames per

125
00:09:06,959 --> 00:09:12,959
real frame and then stitching them all together to make a single 4k frame

126
00:09:11,760 --> 00:09:17,519
now if you're willing to accept the additional input leg that we saw it

127
00:09:14,880 --> 00:09:24,320
actually works really well it's also conveniently how we get 240 hertz out of

128
00:09:20,720 --> 00:09:27,680
this projector instead of a single 4k 60

129
00:09:24,320 --> 00:09:31,040
image they stop the pixel shifting and

130
00:09:27,680 --> 00:09:33,600
just give us the 1080p signal 240 times

131
00:09:31,040 --> 00:09:36,560
a second 60 times for 240 right quick math now

132
00:09:35,200 --> 00:09:41,040
there's another thing that we wanted to try and we obviously saw that in a

133
00:09:39,200 --> 00:09:48,000
completely dark room the performance is way better but optima does have a bright

134
00:09:45,120 --> 00:09:52,000
mode so uh it only gives you 4 000 hours of lamp life but i do kind of want to

135
00:09:50,080 --> 00:09:55,279
know if it's any good oh we actually don't know how to enable

136
00:09:53,519 --> 00:09:59,600
it well never mind we won't be trying it because um

137
00:09:57,120 --> 00:10:04,720
you have to go out of HDR mode in order to uh use that so that's pretty dumb one

138
00:10:02,720 --> 00:10:08,480
of the other good things about the uhd30 over previous generations of dlp

139
00:10:06,399 --> 00:10:13,200
projectors though is its ability to tilt the mirrors plus or minus 17 degrees

140
00:10:11,120 --> 00:10:16,959
which is 40 more compared to the last generation this improves contrast

141
00:10:15,360 --> 00:10:20,720
because it lets the mirrors redirect light away from the lens more

142
00:10:18,800 --> 00:10:25,040
effectively of course we're going to want to see how that goes so let's do a

143
00:10:23,040 --> 00:10:30,720
quick contrast measurement we've got .35 lumens on one of our black

144
00:10:27,760 --> 00:10:34,800
squares and 23.9 on one of our white squares what does that work out too is

145
00:10:32,560 --> 00:10:38,959
that it that doesn't seem right is the rated contrast ratio at like

146
00:10:37,440 --> 00:10:44,480
you know a millimeter from the lens or what because i get 776 there okay

147
00:10:42,800 --> 00:10:48,640
i think it's not broken we know that our testing environment

148
00:10:46,480 --> 00:10:52,880
isn't perfect for this but the reality of it is nothing in the real world is

149
00:10:50,480 --> 00:10:56,720
because even if you have a completely lightless room you're still going to

150
00:10:54,560 --> 00:11:01,200
have light from the bright parts of your scene on the projector screen bouncing

151
00:10:59,279 --> 00:11:06,399
around in it and it's pretty clear from what we measured that this thing is not

152
00:11:03,360 --> 00:11:09,440
even close to the advertised contrast

153
00:11:06,399 --> 00:11:10,800
ratio the good news is that it still

154
00:11:09,440 --> 00:11:15,920
looks pretty darn good if you're in a dark room the bad news is that projector

155
00:11:13,440 --> 00:11:19,600
manufacturers really need to stop making up meaningless numbers to describe their

156
00:11:17,600 --> 00:11:25,040
products because optima says that this has a 500 000 to 1 contrast ratio

157
00:11:22,959 --> 00:11:29,440
get freaking real so the conclusion is the same as it

158
00:11:27,120 --> 00:11:35,360
usually is if you don't have complete light control maybe a big fat vizio tv

159
00:11:32,800 --> 00:11:39,440
