00:00:00.880 --> 00:00:08.559
here at Linus tech tips we know we are occasionally

00:00:05.680 --> 00:00:13.519
a little late to the party for example uploading videos about a new apple

00:00:11.120 --> 00:00:16.480
product days after the initial coverage wave has come and gone you know it is

00:00:15.440 --> 00:00:23.920
what it is we try whatever get off my back

00:00:21.359 --> 00:00:29.519
but not today no what i'm showing you guys today

00:00:26.400 --> 00:00:31.279
is not stale at all in fact

00:00:29.519 --> 00:00:35.760
i don't think i'd even describe it as ripe yet i mean look

00:00:33.360 --> 00:00:39.600
it doesn't even have room in the box for the power adapter it's just

00:00:37.760 --> 00:00:47.200
it's just separate this

00:00:40.960 --> 00:00:49.600
is the first look at the full 4k 120 kit

00:00:47.200 --> 00:00:55.920
but what's that and where did it come from

00:00:58.800 --> 00:01:05.680
browse privately and securely with tunnelbear the simple vpn app start your

00:01:03.760 --> 00:01:09.760
seven day free trial at the link in the video description

00:01:07.439 --> 00:01:12.799
okay so first things first i gotta say i'm a little unnerved by this box

00:01:11.680 --> 00:01:18.880
because there is no friggin way

00:01:15.439 --> 00:01:21.040
that a monitor and a stand for a monitor

00:01:18.880 --> 00:01:24.799
are fitting in here and like look at this

00:01:22.000 --> 00:01:29.439
we got like a handwritten note here take care

00:01:26.400 --> 00:01:32.400
made by hand and then we've got the name

00:01:29.439 --> 00:01:37.439
of the guy aziz who made it so this is z's from z's works

00:01:35.520 --> 00:01:42.320
oh boy wow what the heck

00:01:39.840 --> 00:01:46.799
this thing is just like a completely naked panel and

00:01:44.159 --> 00:01:50.880
oh my gosh there's just like exposed pcbs on the

00:01:50.000 --> 00:01:58.640
back there's no stand no plastic housing um

00:01:56.479 --> 00:02:03.920
too it's credit okay to its credit it does have a vase amount here but

00:02:01.759 --> 00:02:10.319
no way okay there's only three there's only

00:02:06.000 --> 00:02:10.319
three mounting points here um

00:02:10.399 --> 00:02:15.360
there we go i i got it and i oh this is

00:02:15.840 --> 00:02:24.480
i think i found the nut okay so we've got it mounted now we just

00:02:20.400 --> 00:02:25.760
used this um random monitor ARM that we

00:02:24.480 --> 00:02:29.760
found and look at this weird stuff we got

00:02:28.319 --> 00:02:36.239
going on here so this right here

00:02:32.239 --> 00:02:40.160
is a jtag programmer for updating the

00:02:36.239 --> 00:02:41.040
firmware of and debugging the main chip

00:02:40.160 --> 00:02:46.480
and this like taped on doodad here is

00:02:44.560 --> 00:02:52.640
actually a usb to serial adapter for debugging

00:02:49.599 --> 00:02:55.680
everything else the monitor comes with a

00:02:52.640 --> 00:02:57.840
heap of technical documentation to help

00:02:55.680 --> 00:03:05.840
you do all of these things and you can even reprogram the led backlight driver

00:03:02.080 --> 00:03:08.239
if that tickles your pickle okay so it's

00:03:05.840 --> 00:03:12.239
probably clear to most of you by now that the reason

00:03:10.080 --> 00:03:18.480
this thing is here in our shop is clearly nothing to do with how polished

00:03:15.680 --> 00:03:24.239
and finished it is as a product it's because it's the first

00:03:21.040 --> 00:03:28.000
monitor to reach our lab that runs at

00:03:24.239 --> 00:03:28.760
3840 by 2160 4k

00:03:28.000 --> 00:03:36.799
at 120 hertz that's right you gamers can have your

00:03:32.799 --> 00:03:37.760
cake and eat it too with high resolution

00:03:36.799 --> 00:03:43.680
and high refresh rate but how did a small fish like

00:03:42.480 --> 00:03:49.920
aziz pull this off before the big dogs like

00:03:47.040 --> 00:03:56.319
ASUS and acer who showed off their high refresh rate displays at ces this year

00:03:54.080 --> 00:04:03.280
a quick implementation of the displayport 1.4 standard and that is a

00:04:00.879 --> 00:04:09.280
negatory general uh because check this out we've actually got two

00:04:06.000 --> 00:04:12.799
DisplayPort inputs here one right there

00:04:09.280 --> 00:04:15.680
and one right there so i guess let's

00:04:12.799 --> 00:04:20.079
start by firing it up with just one connected

00:04:17.840 --> 00:04:20.079
um

00:04:21.359 --> 00:04:28.400
there uh okay so check this out there's

00:04:27.759 --> 00:04:35.280
no normal on-screen display but

00:04:31.360 --> 00:04:37.759
it does have these completely unlabeled

00:04:35.280 --> 00:04:41.919
buttons up here that hold on a minute

00:04:39.040 --> 00:04:44.800
is this thing completely held on by one screw at the top

00:04:45.440 --> 00:04:54.160
okay so as i was saying it has these unlabeled buttons that helpfully

00:04:50.720 --> 00:04:55.680
come with this handwritten user guide to

00:04:54.160 --> 00:05:00.320
tell me what they're for so there's power oh so oh sorry no power is labeled

00:04:58.720 --> 00:05:06.320
so why don't we start with that one we'll press it

00:05:02.720 --> 00:05:07.600
wow that turns on really quickly okay so

00:05:06.320 --> 00:05:10.880
the next two are for adjusting brightness okay so

00:05:09.759 --> 00:05:18.479
technically there's a label there there's a plus and a minus oh yeah you're doing pretty well here and then

00:05:15.759 --> 00:05:24.560
there's other ones for switching between a bunch of different edid profiles for

00:05:22.400 --> 00:05:27.759
reported resolution and refresh rate starting with

00:05:25.800 --> 00:05:32.080
540p at

00:05:29.720 --> 00:05:35.520
480 hertz and

00:05:33.280 --> 00:05:42.160
wow this looks pretty crap um

00:05:38.720 --> 00:05:46.800
i mean it it has like an interlaced look

00:05:42.160 --> 00:05:49.280
to it and quite honestly like in motion

00:05:46.800 --> 00:05:54.560
even the tn pixels can't switch fast enough to avoid having like a a purple

00:05:52.000 --> 00:05:58.800
trail behind black objects but boy does that ever feel

00:05:56.639 --> 00:06:05.600
butter smooth wow then the next switch is 720p at up to

00:06:02.880 --> 00:06:10.080
300 hertz which is still really darn smooth

00:06:06.560 --> 00:06:12.240
and is at least i can tell if it's a ct

00:06:10.080 --> 00:06:20.479
or a terrorist at this resolution compared to 540p the next one is 1080p

00:06:17.280 --> 00:06:21.840
at up to 240 hertz and i can see how

00:06:20.479 --> 00:06:26.080
this feature would be useful when you look at how quickly it switches modes if

00:06:24.160 --> 00:06:30.639
you're the kind of person who often finds yourself dialing back the

00:06:27.919 --> 00:06:34.319
resolution to get more FPS out of games like cs go

00:06:32.240 --> 00:06:39.120
and then wants to turn up the resolution for sightseeing games like uh

00:06:36.720 --> 00:06:44.400
civilization vi or skyrim i mean these buttons really do make switching super

00:06:41.919 --> 00:06:49.759
easy or maybe it's dumb let us know in the comments if you think you would

00:06:46.400 --> 00:06:54.080
actually use these or not

00:06:49.759 --> 00:06:55.199
so okay here we are 1080p 240 hertz

00:06:54.080 --> 00:07:01.280
pretty sick but it's not the native resolution so

00:06:58.400 --> 00:07:05.919
you're dealing with interpolation and there are already monitors that are

00:07:03.440 --> 00:07:10.880
actually designed to run at that resolution and that refresh rate

00:07:09.280 --> 00:07:17.199
so then let's get finally to good old-fashioned

00:07:14.720 --> 00:07:19.680
4k 60 hertz and then

00:07:20.880 --> 00:07:29.919
um okay so we were expecting 4k 120 hertz here

00:07:27.360 --> 00:07:33.919
but we got a visual demonstration of the limits

00:07:30.960 --> 00:07:38.400
of displayport 1.2 it just can't push that much data

00:07:35.360 --> 00:07:44.599
so instead it has to compromise

00:07:38.400 --> 00:07:44.599
let's plug in a second displayport cable

00:07:44.639 --> 00:07:50.960
well that didn't happen in any of our testing before we go to film

00:07:48.880 --> 00:07:58.240
you can see the right side of the screen is a little bit uh wonka but

00:07:54.479 --> 00:08:03.199
we have still had for the first time the

00:07:58.240 --> 00:08:04.960
experience of 120 hertz gaming at 4k

00:08:03.199 --> 00:08:16.319
resolution and given that we've got this game running at about 150 to 200 FPS

00:08:09.680 --> 00:08:16.319
it is definitely a thing to behold now

00:08:16.720 --> 00:08:23.520
is this the optimal situation with the whole thing going on with the uh

00:08:21.919 --> 00:08:26.479
flickering on the right hand side of the screen and all that

00:08:24.960 --> 00:08:30.400
obviously not but i guess velo learned a valuable

00:08:28.400 --> 00:08:35.120
lesson about shipping

00:08:32.240 --> 00:08:37.839
display controllers that literally have unstable

00:08:36.479 --> 00:08:42.560
pinned onto the back of them so in summary then

00:08:40.080 --> 00:08:46.000
aside from this glitchiness right when we go to film

00:08:44.399 --> 00:08:50.160
this works but how do you buy one

00:08:48.000 --> 00:08:53.600
the answer is you don't yet

00:08:51.040 --> 00:08:58.080
and you may never be looking at a traditional

00:08:54.800 --> 00:09:00.240
finished monitor from this works

00:08:58.080 --> 00:09:05.440
their special sauce is in the development that they're doing on custom

00:09:02.959 --> 00:09:10.959
electronics and the concept that they want to crowdfund is the idea of diy

00:09:09.279 --> 00:09:16.959
enthusiasts being able to buy their module and slap

00:09:14.480 --> 00:09:20.839
it onto an existing panel whether through a bundle from zeesworks or off

00:09:19.360 --> 00:09:26.320
ebay or whatever there will always be drawbacks

00:09:24.160 --> 00:09:30.959
to an approach like this the calibration and display tuning that

00:09:28.800 --> 00:09:35.279
goes on with a finished product was clearly not present on our intellux

00:09:33.360 --> 00:09:41.120
m280dj dash l30 and you won't get fancy

00:09:37.839 --> 00:09:43.760
features like g-sync anytime soon but

00:09:41.120 --> 00:09:48.240
zswork has tested other options like a 39-inch mba panel and they say it works

00:09:46.399 --> 00:09:53.360
pretty similarly and they're also expecting costs for diy monitor

00:09:51.200 --> 00:09:59.760
solutions like this to be hundreds of dollars cheaper than 120 hertz 4k gaming

00:09:56.880 --> 00:10:03.680
monitors from traditional companies so yay or nay

00:10:01.440 --> 00:10:07.120
diy mix and match monitors and electronics

00:10:05.360 --> 00:10:12.160
whatever you guys say down in the comments below i know i'll be watching

00:10:09.360 --> 00:10:17.120
this concept really closely have you ever thought to yourself

00:10:14.240 --> 00:10:22.000
if only there was some easy affordable way to make my own website

00:10:19.839 --> 00:10:26.880
