in a recent video we gamed on the first 8K consumer display and the conclusion
we came to was that given all the Hoops we had to jump through to get any more
than 30 htz working at
8K uh pretty much wasn't worth the
hassle and we were going to have to wait for this technology to become practical
but then Sharp Electronics watched that
video and basically said hey um it
really shouldn't be that difficult to get it working all you need is the right
TV so their commercial display group
sent over
this Sharp's
70in akk TV that actually utilizes not
one not two not three but four
concurrent HDMI connections to achieve a
true 8K 60 HZ functionality supposedly
with no hassle whatsoever well I have a way of creating
hassle where no hassle existed before so I truly wish them luck with
that step number one
stand it's the easy part step number
two power cable still easy step number
three gaming PC powerful enough to run
8K
God step four introduce Andy who just
cleared his probation you don't have to duck from the camera anymore
dude all right do you want to give me a hand with this sure oh so uh let's go
ahead and I'm going to tip it your way
so we're going to put the stand on with it upside down okay do you want to grab
the that screwdriver yeah I have the screwdriver it's okay I got
this you can you can trust me he thinks I might drop
it it's fine got to say the packing for this is
definitely more rud I think this is like a a demo unit for
sending to potential commercial customers or something there's no I
don't even think there was a remote in the box so really clean looking TV very
little branding got your sharp logo over here Aquos and then you've just got 8K
7680 by 4320 pixels baby okay here we
go now these HDMI cables are nothing special but but theoretically each one
of them is only carrying a 4K 60 signal
which should be fine just fine except
for one small problem no modern graphics
card contains more than usually one or
two HDMI connections now we tried a
solution a little while ago where we used four graphics cards in a Quadro
Mosaic display thing to drive quadrants
of a monitor it didn't work at all it was super stupid performance sucked but
fortunately adapters to the rescue so these are active display port to HDMI
2.0 adapters that I acquired for that
failed project and I am hoping to finally see some success with today so
we're going to get these bad boys plugged in oh
wait
oh I had this totally wrong before so
when I pointed at the HDMI ports before that was completely wrong the HDMI ports
I wanted were down here so these are all
just individual normal HDMI ports this
is a single input input 7 8K signal
input and it's got like cable management clips for it and all that shiz so just
like that experiment with each separate graphics card running a different
quadrant of the display this display does split input 7 into quadrants but
unlike that one we're using a single graphics card with its single frame
buffer in order to drive all four quadrants or rather I should say we're
using two in SLI but they're all hooked up to a single one so we don't need any
kind of external synchronization card or anything like that it th should
theoretically just work believe it or not this is how they usually run like
future panel technology demos at trade
shows like CES except instead of actually building them into a real
commercialized product they just do it on like a crazy hand soldered thing that
sits under the curtain that looks
great I'm like feeling the uh what is it
what was it maxl or something Memorex like you know that classic
commercial but now it's 8K gaming no
signal from external device hey bottom
right grabbed a signal
holy it's on the whole display no hold on a
minute no way there's no way it's going
to just run 8K effortlessly okay one of them's running
at 50 htz why would that be and how
would that that's bizarre why would anyone want that one running at 50 and
the other's running at 60 okay let's have a let's have a quick boo here so we
need to grab some games we're going to get that going but in the
meantime no this did not quite work perfectly out of the box and I do think
we have a little bit of configuration to do so let's start by figuring out which
one of these is broken I suspect the one
that's running at 50 HZ but uh only one way to find out for
oh and that wasn't it oh
boy oh boy okay maybe just enter we'll do it no
of course not did it oh boy what is
oh He's dead Jim this isn't even working in the Bios
now this is more broken than it was when we started I have a way of creating
hassle where no hassle existed before okay so it's running but still not
correctly however before we move forward
I've got a bit of an update for you guys as it turns out at least one of the
problems we had was caused by nvidia's
seemingly arbitrary limitation on their
consumer graphics cards that only allows you to set up an EnV surround
configuration with a maximum of three
displays so this system is out and my
test bench is in so we've hooked this up
with two gv100 Quadro graphics cards
these have 32 gigs of RAM over 5,000 and Cuda Cor in terms of their gaming
performance they shouldn't be that far off something like an RTX 2080 I mean
they're not quite there but they're certainly closer to that than they are to a 1080 TI then we ran into another
problem remember how I had three of these display port to HDMI adapters well
these cards only have display port outputs so I had to use display port to
DVI DVI to HDMI and then that to the TV
so while we are actually running
an Nvidia Mosaic configuration here and
we can see that if we pull up the Nvidia control panel and theoretically when we
go to manage GPU utilization here we're
running an SLI but the SLI menu item went away once
we configured Mosaic and it doesn't appear that our second GPU is actually
doing anything for now this is what we're stuck with though and damn it I
want to see 8K so
we've got another one of these display ports HDMI adapters and you guys are
coming with me for the ride of even if
the performance sucks finally getting an 8K output
here all right once these are numbered
oh I see that's a new one I have literally never seen it do that before
okay sure why not remember Windows 95
guys remember you know who I really feel bad for in all of this is is sharp they
reach out they go y you really shouldn't have to jump through a bunch of stupid
Hoops to get 8K 60 Herz going on a PC
and as far as I can tell none of this is their fault but this is an awful lot of
stupid Hoops okay so I know set up multiple displays is not the Mosaic
configuration thing but the reason that I set all this up correctly was that I
was hoping that now when we go to set up mosaic it'll kind of grab that
everything is the way it's supposed to be and it'll work come
on okay well it's letting me click next and that's
correct okay let's
try the other graphics card I don't know
I did noticed that even though we're plugged into the one that would normally be in the primary slot in the
motherboard it's identifying as GPU 2 so
who knows maybe this will help or something
time for some more lunch frankly I'm pretty close to the
end of my rope I was doing some offscreen troubleshooting involving uh
trying older quadros so uh GP 100s
instead of the uh GV 100s I did a full
platform swap in so motherboard CPU
changed them out I don't know and it's always the
same thing I click apply it
goes and then there's no finish but I do
not accept that conclusion and I have decided to try one
last thing we're going to go
AMD okay so according to this community
post it's possible but I think I know
why it might not be working I think it might just be
grabbing my configuration from Windows and then
assuming that I want a 4x1 okay your display configuration has
been updated reenable Affinity display
group no
why the fact that it's reenable is what's tripping me out here I don't want
to reenable it I want to enable a new
different one that is not like what I had before I don't know how to start
fresh when I disable it and it only prompts me to reenable it just AMD
things like if only this one thing it would have been easy Nvidia thinks oh
it's not working to be clear neither of them is
giving me a working 60 HZ 8K display well other than the boneheaded
driver limitation that doesn't allow me to arrange it in a 2X two this was a
much better experience but due to the boneheaded driver implementation that
doesn't let me arrange it in a 2X two I guess we're going back to our next best
lead which is Quadro to see if maybe we can get that to
work it's been a few more hours and a Lifeline has arrived we now have oh
no if they only shipped two I'm going to be so
upset one two no there's four
okay the good news though I also reached
out to Sharp and I was like what cables did you guys use to get this working cuz
they assured me it was be no problem piece of cake piece of crumb cake and
they said they got these cables from PC
cable world I guess so these are display
port to HDMI cables rather than adapters
theoretically that is exactly the same
thing but at this point I don't know if I know anything anymore if this doesn't
work I'm officially
stumped here we go
one 2
three four wow okay that did grab 4K 60
HZ on all four of them really fast you have got to be kidding
me it works oh yeah
so after all
that with adapters we could do four times
4K but heaven forbid we want to run them
in Mosaic on Nvidia with adapters on AMD we could do
4X one at 4K but heaven forbid we want to
rearrange them like this oh it stopped
wait what like stop stop don't do like whatever you're changing now control
panel stop changing it because everything is working this is right stop
stop changing things finish finish oh
could I just could I just kill the task I wonder if I can just kill the task
Nvidia control panel end task it
worked 100% scaling show me that native AK baby
wow 60 htz
akk there it is launching
ano so at 8K Max draw distance the game
wouldn't even launch but we've got it at full medium 8K but there's bad news too
it drops to 30 frames per second in the
menu when it sits at 60 at the main menu
this does not bode well for performance
wow this is so like
disorienting sitting this close to the city one of the issues with this game's
interface in
general and we're back so one of the problems that I have with this game in
general is that you can't zoom the interface out far enough and I
especially feel it like this cuz sitting this close to it honestly is very
comfortable in terms of the detail of the game like even at the max zoom level
let's go ahead and find one of our wood cutters again here this guy walking as
cow that is UNF freaking believable I
don't even have anti-aliasing on I have zero anti-aliasing on right now can you
believe that Brandon doesn't that look
nuts man that's crazy I love it so that was it for ano
now we're firing up shadow of the Tomb Raider to see how a uh like a third
person Adventure game feels at 8K so far pretty good
I mean it's obviously not running great uh we're looking at about 7 to 20 FPS in
menu and that's reported by fraps that's clearly not even accurate wow the
hair and this is with no
anti-aliasing is incredible hey
huh actually in motion it's not nearly
as convincing part of that could be the 19 frame per second performance though
you know say what you will about Nvidia art R TX and the performance impact and
all that but you've got to respect Nvidia for recognizing that resolution
is no longer the biggest bottleneck in
gaming image quality and just trying something anything else cuz sitting at a
reasonable distance like yeah that looks
crisp AF but is it really that much
better than 4K that does look real sharp though
pardon the pun so there you go guys about 15 grand worth of Graphics
horsepower we're looking at 20 FPS
average pretty sick let's see how many FPS we get in
rocket League hey Riley you want to play rocket league for me help me Riley what
play at 8K whoa what really it's at 8K
yeah whoa that is your keyboard working
hold on there you go wait what there you go okay whoa
like it's one thing being this close to like a huge TV like this but it is like
actually sharp oh yeah is it a sharp tv
yeah like everything down to the tread like you can really tell that the the
video crowd is just balls yeah cuz they look so sharp yeah I
have never seen this game look this good so could you get into playing on a big
screen like this size at this kind of resolution I think I could get into it
yeah probably so I guess that's pretty much the conclusion of this video is AK
cool yeah really freaking cool it's
glitchy right now and we don't have the performance that we need for it to run
its best but when it works man is that
incredible now I don't think that sitting this close to a TV in order to
appreciate the extra sharpness that at provides is necessarily practical but
that doesn't mean that in applications like V are where the display is much
closer to your eyes and you really need that resolution so you don't get a screen door effect that it won't be an
incredible Difference Maker moving forward we just need much more powerful
graphics cards and obviously some work on the software side but with the whole
you know not wanting to crash all the time and all that speaking of not
wanting to crash all the time I'd hate for you guys to get bored and crash out
of this video before I tell you about our sponsor the Mast drop hd6xx
headphones are one of Mast drops all alltime best sellers with over 60,000
units sold and no wonder because they've got an unchanged driver structure from
the hd650s which are an absolute Legend
they've got a detachable 6-t cable instead of a 10-ft cable unlike the HD
650s but the sound signature is unchanged so you've got nice balanced
mids natural sounding base and they're open back for a nice natural Sound Stage
they come with sennheiser's long-term support and you can buy them at the link
below at drop.com so thanks for watching

like get subscribed or maybe consider checking out where to buy the stuff we
featured at the link in the video description I actually think this is one of their commercial products I have no
idea if you can buy it also in the video description is our merch store which has
