 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 30Hz working at 8K, pretty much wasn't worth the hassle, and we were gonna have to wait for this technology to become practical. But then Sharp Electronics watched that video, and basically said, hey, 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 70-inch 8K TV that actually utilizes not one, not two, not three, but four concurrent HDMI connections to achieve true 8K 60Hz 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.

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? Oh, so 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. OK, do you want to grab that screwdriver? It's OK. I got this. You can you can trust me. He thinks I might drop it. Well, it's fine. Got to say, the packing for this is definitely more rudimentary. I think this is like 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. I'll quote. And then you've just got 8K 7680 by 4320 pixels, baby. OK, here we go. Oh, now these HDMI cables are nothing special, 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 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, what is it? What was it? Maxcell or something? Memorex? Look, you know that classic commercial, but now it's 8K gaming. No signal from external device. Hey, bottom right, grabbed a signal. Holy sh**. It's on the whole display. Hold on a minute. No way. There's no way it's going to just run 8K effortlessly. Okay, one of them is running at 50 Hertz. 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 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 Hertz. But only one way to find out. Oh, and that wasn't it. Oh, boy. Oh, boy. Okay. Maybe just enter will 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 NV 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 CUDA cores. 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 DisplayPort to HDMI adapters? Well, these cards only have DisplayPort outputs, so I had to use DisplayPort 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 DisplayPort to 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 Sharp. They reach out, they go, yeah, you really shouldn't have to jump through a bunch of stupid hoops to get 8K 60Hz 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 setup 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 setup 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 notice that even though we're plugged into the one that would normally be in the primary slot on 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 off-screen troubleshooting involving trying older Quadros, so GP100s instead of the GV100s. I did a full platform swap, so motherboard, CPU, changed them out. I don't know, and it's always the same thing. I click apply, it goes blibblibblibblibblabla, and then there's no finish. But I do not accept that conclusion, and I have decided to try one last thing. We're gonna 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 four by one. Okay, your display configuration has been updated. Re-enable iFINITY display group. No, why? The fact that it's re-enable is what's tripping me out here. I don't want to re-enable 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 re-enable it. It's just AMD things. Like if only this one thing, it would have been easy. Nvidia things. Oh, it's not working? To be clear, neither of them is giving me a working 60Hz 8K display. Well, other than the boneheaded driver limitation that doesn't allow me to arrange it in a two by two, this was a much better experience. But due to the boneheaded driver implementation that doesn't let me arrange it in a two by 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? Because they assured me it would 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, two, three, four. Wow. Okay. That did grab 4K 60 Hertz on all four of them really fast. You have got to be kidding me. 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 four by 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. 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 8K, baby. Wow. 60 Hertz, 8K. There it is. Launching Anno. 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 because 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 is cow. That is un-freaking-believable. I don't even have anti-aliasing on. I have zero anti-aliasing on right now. Can you believe that, Brennan? Doesn't that look nuts? Man, that's crazy. I love it. So that was it for Anno. Now we're firing up Shadow of the Tomb Raider to see how a third-person adventure game feels at 8K. So far, pretty good. I mean, it's obviously not running great. 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. Huh. Really in motion. It's not nearly as convincing. Part of that could be the 19 frames per second performance, though. Say what you will about Nvidia RTX 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. Because 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? It's at 8K, yeah. Whoa. That is sharp. Is your keyboard working? Hold on. There you go. Wait, what? There you go. 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 video crowd is just balls. Yeah. Because 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 to this video. Is 8K 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 8K provides is necessarily practical. But that doesn't mean that in applications like VR, 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 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 Mastrop HD 6XX headphones are one of Mastrop's all-time best sellers with over 60,000 units sold and no wonder because they've got an unchanged driver structure from the HD 650s, which are an absolute legend. They've got a detachable 6-foot cable instead of a 10-foot cable, unlike the HD 650s, but the sound signature is unchanged. So you've got nice balanced mids, natural sounding bass, and they're open back for a nice natural soundstage. They come with Sennheiser's long-term support and you can buy them at the link below at drop.com. So thanks for watching guys, if you disliked this video, you can hit that button. But if you liked it, hit 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.
