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

00:00:04.080 --> 00:00:09.280
dang there's nothing quite like a giant

00:00:07.279 --> 00:00:14.880
projector screen is there this doesn't look like very gamery packaging

00:00:11.840 --> 00:00:18.080
but with a lightning fast 240hz refresh

00:00:14.880 --> 00:00:19.760
rate 15.7 milliseconds of input lag and

00:00:18.080 --> 00:00:25.359
HDR support with up to a 120 inch screen this

00:00:22.720 --> 00:00:31.039
projector sounds too good to be true but optimus says it is true they claim that

00:00:27.840 --> 00:00:34.079
their uhd30 is designed from the ground

00:00:31.039 --> 00:00:36.480
up for all gaming and delivers an

00:00:34.079 --> 00:00:41.040
unmatched gaming experience but can it possibly get even close to what you

00:00:38.960 --> 00:00:46.399
would experience from a tv or even just a really big monitor can you actually

00:00:42.960 --> 00:00:49.680
get a convincing HDR gaming experience

00:00:46.399 --> 00:00:52.879
from a 1300 dlp projector what corners

00:00:49.680 --> 00:00:55.120
had to be cut to manage a 240 hertz

00:00:52.879 --> 00:01:00.640
refresh rate is this gonna turn into one of those like nonsense debunking

00:00:58.160 --> 00:01:04.320
manufacturer say videos why hasn't Linus told us about the

00:01:02.079 --> 00:01:08.880
sponsor yet soundcore has released its latest wireless earbuds the liberty air

00:01:06.320 --> 00:01:12.880
2 pros they feature clear audio and multi-mode active noise cancellation

00:01:11.040 --> 00:01:16.400
learn more at the end of the video or at the link in the video description

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

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

00:01:32.560 --> 00:01:40.240
within reach of consumers and compared to past gaming projectors that focused

00:01:37.759 --> 00:01:46.000
on the stereoscopic 3d experience the uhd30s list of specs is more relevant to

00:01:43.600 --> 00:01:48.920
today's discerning gamer including the standout features we want to investigate

00:01:47.759 --> 00:01:55.600
today 240hz refresh rate at 1080p and

00:01:51.920 --> 00:01:57.759
acclaimed 15.7 milliseconds of input lag

00:01:55.600 --> 00:02:02.320
now obviously neither of these numbers are on par with the best gaming monitors

00:02:00.079 --> 00:02:10.160
today but in the projector world where it's common to see 80 milliseconds of

00:02:04.560 --> 00:02:10.160
lag this is a potential game changer

00:02:11.760 --> 00:02:19.040
get it optima claims this unit can project an image up to 300 inches

00:02:16.640 --> 00:02:23.520
diagonally but you're gonna start losing brightness and contrast pretty hardcore

00:02:22.239 --> 00:02:28.239
not to mention that you would need an absolutely massive room for that to make

00:02:25.920 --> 00:02:35.120
any sense whatsoever i mean the image alone would be over 12 feet tall and 22

00:02:32.160 --> 00:02:39.599
feet wide also this is not a short throw projector so

00:02:36.879 --> 00:02:44.560
we settled on a 100 inch image which already requires at least 11 feet

00:02:42.640 --> 00:02:51.840
between the projector lens and the surface of our screen we wanted to go

00:02:46.560 --> 00:02:51.840
300 inches we need to back it right up

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

00:02:56.800 --> 00:03:01.760
seamless white paper isn't going to give us the best performance but it'll be

00:03:00.400 --> 00:03:05.840
better than the painted walls that we have here so for a real setup you should

00:03:04.080 --> 00:03:09.840
always leave him in your budget for a proper screen

00:03:07.440 --> 00:03:12.959
hey wait a minute what is this nicholas

00:03:10.959 --> 00:03:18.959
you couldn't be arsed to fix the trapezoid shape of the image the problem

00:03:15.680 --> 00:03:21.519
is nicholas did notice this problem and

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

00:03:23.599 --> 00:03:28.959
product page let's play around with the settings of it shall we oh enhanced

00:03:27.280 --> 00:03:33.920
gaming well we definitely want enhanced gaming don't we the enhanced gaming mode

00:03:30.959 --> 00:03:39.040
dramatically lowers the input leg but it does come at a cost once you've enabled

00:03:36.239 --> 00:03:43.120
it you can see here that our image is in fact square now

00:03:40.720 --> 00:03:47.360
but that's only because our projector happens to be sitting in exactly the

00:03:45.040 --> 00:03:53.440
right position when you turn on enhanced gaming which you need for that low input

00:03:49.760 --> 00:03:56.000
leg keystone adjustments cannot be made

00:03:53.440 --> 00:04:00.959
so if we wanted to mount our projector up by the ceiling and have our screen

00:03:58.400 --> 00:04:06.000
down closer to our couch level we would simply not be able to do that without

00:04:03.360 --> 00:04:09.680
experiencing some kind of distortion of the image it's probably worth mentioning

00:04:07.840 --> 00:04:14.400
that if you don't care about input lag it does have 40 degrees of keystone

00:04:11.760 --> 00:04:20.400
correction but it's vertical only not horizontal so then i'm gonna grab this

00:04:16.840 --> 00:04:21.519
lttstore.com CPU pillow

00:04:20.400 --> 00:04:27.040
oh yeah get comfortable and assume that i am

00:04:24.160 --> 00:04:31.199
some kind of genius whiz kid projector mounting master and that we can get it

00:04:29.280 --> 00:04:34.639
configured right without relying on keystone and actually play some freaking

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

00:04:38.720 --> 00:04:46.080
HDMI 2.0 which you'll need for 240hz 1080p after a little bit of tinkering

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

00:04:48.479 --> 00:04:54.160
where games will think that the projector's default resolution is

00:04:52.160 --> 00:05:00.800
1920x1200 which is not supported at 240 hertz so

00:04:57.280 --> 00:05:00.800
it can get a little confused

00:05:01.199 --> 00:05:08.800
that feels pretty darn responsive and HDR makes a big difference on a

00:05:06.240 --> 00:05:12.560
projector actually i'm pretty impressed by how black

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

00:05:13.759 --> 00:05:20.880
looking just kind of gray because there's not enough contrast overall this

00:05:17.360 --> 00:05:23.680
game is a little dark right now for me

00:05:20.880 --> 00:05:28.639
though wow that really does feel pretty darn good i'm definitely noticing

00:05:26.400 --> 00:05:34.000
though that at a comfortable distance for the size of this image i am seated

00:05:31.680 --> 00:05:38.400
right next to the freaking projector which has kind of an annoying fan in it

00:05:36.639 --> 00:05:42.560
and also i'm not able to sit dead center in front of

00:05:40.080 --> 00:05:45.840
the screen because i would block it not having any keystone adjustment

00:05:44.000 --> 00:05:49.280
definitely an oversight but i can't fault the responsiveness

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

00:05:52.639 --> 00:05:57.840
for those who aren't familiar the rainbow effect is a phenomenon where as

00:05:56.240 --> 00:06:01.759
your eyes move around to look at different parts of the image or as

00:05:59.680 --> 00:06:07.199
objects move around on the screen you can see a kind of weird

00:06:03.680 --> 00:06:09.440
rainbowy fringing at the edges that is

00:06:07.199 --> 00:06:14.160
can be quite distracting for some people and impossible to notice for others i'm

00:06:12.160 --> 00:06:19.520
reasonably sensitive to it and what it basically means if we don't see it here

00:06:16.400 --> 00:06:21.120
is that the mirrors are moving so fast

00:06:19.520 --> 00:06:25.600
that they're able to go all the way from one state to another without seeing

00:06:23.280 --> 00:06:29.919
those weird artifacts in between while we were switching over to 60hz 4k we

00:06:27.680 --> 00:06:36.560
noticed another interesting disadvantage of gaming mode 4k looks like absolute

00:06:33.120 --> 00:06:38.560
dog crab text looks i would describe as

00:06:36.560 --> 00:06:44.000
pretty all right we turn enhanced gaming mode on and honestly it looks as bad as

00:06:41.360 --> 00:06:46.560
1080p or maybe even a little worse than what i would expect

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

00:06:49.600 --> 00:06:54.960
would notice in game but on the desktop

00:06:52.800 --> 00:06:58.720
it's pretty jarring like here like these these hanging objects here normally if

00:06:57.120 --> 00:07:02.720
we were at 1080p i would i would definitely see stair stepping and

00:07:00.720 --> 00:07:06.240
aliasing on them but it's like i don't know it's like 4k but

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

00:07:08.319 --> 00:07:14.639
it's really really big text yeah no see this looks crappy weird huh could we

00:07:12.800 --> 00:07:17.919
kill the filming lights for just a short period so i can try it out

00:07:16.880 --> 00:07:22.720
dang this looks freaking awesome now i could

00:07:20.639 --> 00:07:25.840
get used to this and in terms of input lag

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

00:07:27.759 --> 00:07:34.720
there with the best gaming monitors but it's it's fine there's nothing quite

00:07:32.160 --> 00:07:38.960
like a giant projector screen is there now that we've experienced it let's talk

00:07:36.479 --> 00:07:44.319
about how this even works how is optima getting 240 hertz out of a projector how

00:07:41.759 --> 00:07:49.520
do dlp projectors even work well at the core of every dlp projector there's a

00:07:47.120 --> 00:07:54.400
lamp module and the light output is then passed through a spinning color wheel in

00:07:51.520 --> 00:08:00.400
this case it's an eight segment rgbw rgbw wheel this creates a rapid

00:07:57.680 --> 00:08:04.319
repeating sequence of red green blue white red green blue white light

00:08:02.720 --> 00:08:07.680
speaking of RGB and projectors by the way we have a video with a sweet laser

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

00:08:11.919 --> 00:08:18.400
actually just clear this allows for a brighter overall picture the light

00:08:16.160 --> 00:08:23.599
sequence is then reflected off of the digital micro mirror device or dmd

00:08:21.199 --> 00:08:28.319
through the lens and then onto a background of your choice the dmd chip

00:08:25.919 --> 00:08:32.399
in the uhd30 has an array of mirrors that sit on a hinge with each mirror

00:08:30.160 --> 00:08:36.000
being a pixel and the mirrors arranged in a

00:08:33.240 --> 00:08:40.959
1920x1080 grid these mirrors are digitally controlled switching on and

00:08:38.159 --> 00:08:44.080
off in around one microsecond flipping them from either reflecting light

00:08:42.640 --> 00:08:49.040
through the lens or reflecting light away from the lens

00:08:47.200 --> 00:08:54.959
for reference by the way a single frame at 240hz is about 4100 microseconds so

00:08:52.720 --> 00:09:01.040
these things are moving real fast to get a 4k picture the dmd panel itself is

00:08:58.399 --> 00:09:06.959
actually shifted physically four times per frame so you're literally creating

00:09:03.600 --> 00:09:08.800
four entire 1080p frames per

00:09:06.959 --> 00:09:12.959
real frame and then stitching them all together to make a single 4k frame

00:09:11.760 --> 00:09:17.519
now if you're willing to accept the additional input leg that we saw it

00:09:14.880 --> 00:09:24.320
actually works really well it's also conveniently how we get 240 hertz out of

00:09:20.720 --> 00:09:27.680
this projector instead of a single 4k 60

00:09:24.320 --> 00:09:31.040
image they stop the pixel shifting and

00:09:27.680 --> 00:09:33.600
just give us the 1080p signal 240 times

00:09:31.040 --> 00:09:36.560
a second 60 times for 240 right quick math now

00:09:35.200 --> 00:09:41.040
there's another thing that we wanted to try and we obviously saw that in a

00:09:39.200 --> 00:09:48.000
completely dark room the performance is way better but optima does have a bright

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

00:09:50.080 --> 00:09:55.279
know if it's any good oh we actually don't know how to enable

00:09:53.519 --> 00:09:59.600
it well never mind we won't be trying it because um

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

00:10:02.720 --> 00:10:08.480
of the other good things about the uhd30 over previous generations of dlp

00:10:06.399 --> 00:10:13.200
projectors though is its ability to tilt the mirrors plus or minus 17 degrees

00:10:11.120 --> 00:10:16.959
which is 40 more compared to the last generation this improves contrast

00:10:15.360 --> 00:10:20.720
because it lets the mirrors redirect light away from the lens more

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

00:10:23.040 --> 00:10:30.720
quick contrast measurement we've got .35 lumens on one of our black

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

00:10:32.560 --> 00:10:38.959
that it that doesn't seem right is the rated contrast ratio at like

00:10:37.440 --> 00:10:44.480
you know a millimeter from the lens or what because i get 776 there okay

00:10:42.800 --> 00:10:48.640
i think it's not broken we know that our testing environment

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

00:10:50.480 --> 00:10:56.720
because even if you have a completely lightless room you're still going to

00:10:54.560 --> 00:11:01.200
have light from the bright parts of your scene on the projector screen bouncing

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

00:11:03.360 --> 00:11:09.440
even close to the advertised contrast

00:11:06.399 --> 00:11:10.800
ratio the good news is that it still

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

00:11:13.440 --> 00:11:19.600
manufacturers really need to stop making up meaningless numbers to describe their

00:11:17.600 --> 00:11:25.040
products because optima says that this has a 500 000 to 1 contrast ratio

00:11:22.959 --> 00:11:29.440
get freaking real so the conclusion is the same as it

00:11:27.120 --> 00:11:35.360
usually is if you don't have complete light control maybe a big fat vizio tv

00:11:32.800 --> 00:11:39.440
is a better choice because performance will be better and the cost won't be too

00:11:37.600 --> 00:11:43.360
far off especially once you factor in the price of a projector screen if you

00:11:41.360 --> 00:11:49.440
need keystone this thing is completely out but if you don't need keystone

00:11:45.839 --> 00:11:50.720
is this the projector for gaming

00:11:49.440 --> 00:11:57.120
i mean as long as you're under optimal

00:11:53.360 --> 00:11:59.920
get it because optima optimal conditions

00:11:57.120 --> 00:12:04.720
yeah it's pretty sweet even if they oversell it a fair bit

00:12:02.720 --> 00:12:07.279
