Vizio P series (Sept 24th) + GTX 970/980

I assume by the fact I get boxes on this:

http://www.lagom.nl/lcd-test/white.php

And these:

http://www.lagom.nl/lcd-test/black.php

(although the very low values (1-3) or very high values (253-254) are not viewable unless I really change calibration settings that makes stuff worse for other things.

I got things dialed in a lot better and things are looking much better now and I am back to RGB color space (when i set ycyybr444) things were a little more grey although it helped in some things it seemed to make other things worse.

A lot of stuff won't normally apply to me as I mostly run linux and all my testing (so far) has been linux.

That being said I am installing windows 7 on one of my machines as we speak but its still got some time to go:

The 980 will be going into as I don't have high hopes for HDMI 2.0 support on linux so I can test things on windows.

My main machine is currently very near the end of a world record pi calculation I have been doing for months so I am trying to avoid shutting that one down as I do have a windows install on that (but I almost never use it).

Its now 6:50 PM and still no UPS guy... I paid for expedited shipping so I am gonna be pissed if they do a delivery exception on me. Its always when I am really waiting for a package that they come like as late as freaking possible and I can't even go grab dinner. Usually they come in the middle of the day on the stuff I don't care about.

Tracking still shows out for delivery.

Haha, yeah, how the fuck is it that I feel like I'm always the last stop for my Fedex/UPS guys? Does some lucky guy get his stuff at 9 in the morning or something? :p
 
Well long since windows installed and the guy *finally* got here at 8 PM but now I am starving as i haven't ate dinner and I am not sure if I have enough molex adapters because the case is a supermicro SC846 and the PSU isn't going to have any VGA connectors (which I forgot about). Hopefully I can find some as I don't want to try get some somewhere.

Anyway I will report back within 1.5-2 hours on wether I got things going and 60Hz working.
 
So... not good news.

It looks like the gtx 790 is not able to read the EDID off the TV. This is likely due to the 60 foot HDMI cable I am using. Unfortunately these machines are in my rack and its not really an easy feet to get closer to the machine to try a different cable :(

On linux its pretty easy to get around this.

Amazingly its listing correct pixel clocks in linux when detecting the card and forcing it a dumped EDID I got from laptop:

Its unfortunately but no 4k60 for me.

I suspect it could be my cable because it does do a signal amplification but I thought any cable that could do HDMI 1.4 bandwidth was supposed to do hdmi 2.0 bandwidth..

This is the cable I am using:
http://www.monoprice.com/Product?c_id=102&cp_id=10255&cs_id=1025507&p_id=9173&seq=1&format=2

That being said I am surprised its acting like no signal I would expect atleast some sort of signal. I will test with a seiki as even if its way beyond it it will usually say 'no support' rather than 'no signal' so a bit easier to tell if its actually getting anything or not.
 
Huh.

I looked long and hard at those Red cables (for this approx setup) and decided it was one more thing that could potentially go wrong, or I would wonder about. They seem very intentionally specced per use, vs a thicker dumb cable in which that shouldn't be a problem. Obviously my situation is different (I only need a 10ft cable from HTPC shelf to far-end of the tv) but kind of glad about that choice at this moment...even if the HDMI 2.0 spec Reds are available in 10-15 ft.

Your situation truly is unique, that long of distance is probably a PITA, especially when it's new tech (that probably hasn't been nailed down to an exact science of how far a cable can go per gauge for each setting etc.) It I were you, I guess I would just buy the thickest gauge, shortest 18gbps-rated (for assurance) cable possible...granted at least the Monster cable says it will do what you want on the tin. I feel your pain though, whenever I have to resort to a loathed/gimmick brand for on reason or another (by lack of options or purely because the box says what should be capable but I can't guarantee from other products), I get extremely irritated.

Don't hold me to it, but the longest 18gbps-rated I see is 40ft and 24AWG, which I take to imply it's around the baseline length/gauge for being 2.0 compliant. I would *think* 22AWG could be *slightly* longer. (Yes, that would be a thick-ass cable). I imagine the reason most are only up to ~15ft is so they can keep the cable gauge smaller or wiring used less and remain within spec.

Red | Blue

I hope everything works out for you, and thanks for the update.

Also, thanks for the EDID dump. Obviously it has to have a ~500mhz or so pixel clock, and 600mhz probably is just standard for electronics using the hdmi 2.0 spec, but it's at least encouraging. Perhaps someone could mess with the blanks (overscan) and get 1440p etc working? It's probably just how the scalar works, but I don't want the dream to die just yet. :p

If you have time to post over there, perhaps ToastyX could help make things work (If you need it...it seems you know what you're doing).

Yeah... after some more research it looks like cable spec actually matters on long runs like mine.

The display seems really picky on its modes and doesn't seem to support even things listed in its EDID (it lists 1280x720p @ 120Hz but can't do it). Here is a full list of modes from EDID:

It also can't do 720x480@120.

Dammit. You're telling me 120fps-encoded dvds still won't work!? All none of them? But I've been waiting like 15 years...:(

(But seriously, that's probably for 120fps mpeg video which you prolly know often isn't actually 720x480 in many cases. I don't know if anything like that commercially exists...it sounds like something you'd shoot off a cell-phone or newer digital camera, and is probably supported for files encoded in dvd rez/120fps for that respect via usb/wifi/something like that. The same is probably true for 720p/120; I imagine that is support for decoding actual 720p video content shot at 120fps).

Thanks again, amigo. This is all truly interesting. Hopefully you/we get some better news when you're able to get the cable setup working. :)

Just out of curiousity, did you test these modes at 119hz(or 119.88hz)? I can not remember where I read it (amazon?) but somebody mentioned for their Vizio P, the 120hz mode showed up for them as 118/119hz or something to that effect (I think it was the nvidia panel in windows). Perhaps try that custom res? It would be crazy stupid, yet somehow humorous and conceivable, if it supported 119hz (since NTSC isn't 'quite' 120fps/4 and this seems to be built around that given the EDID) and not actually 120hz.

For the record, I will laugh if that works. Because, man...wow. It would also explain the 4k@60/1080 @ 'higher'...lol...because 120 would be a lie. Perhaps 1080p/119 or 119.88 and 4k/59 or 59.94. Also, where is the ~48hz mode? Wasn't that a promised feature (to playback 24/48fps film/video at proper cadence)?

Sounds like vizio needs to update their firmware imho, which is probably to be expected. Not only is this new, but it's also their (and largely the tv manufacturing industry's) early foray into doing stuff like this.


Curious, did you use nvidia's custom rez or Toastyx's cru? I'm just curious if the actual edid was successfully modded when you tried those modes...because it doesn't seem so (or it would say flat 60/120hz etc instead of or in addition to film/video frame rates for each resolution, wouldn't it?). I know absolutely nothing about Linux, but I know I had to mod the inf for some things to work for my ld450 in windows, on top of butchering the edid in CRU to make it do what I wanted.

Is that how you are keeping your setup? I couldn't imagine sitting that close to a 70" 4K, that is still only 63PPI, and you'd have to gaze upward at most of the screen which is definitely not ergonomically and physiologically optimal. ;)

So... not good news.

It looks like the gtx 790 is not able to read the EDID off the TV. This is likely due to the 60 foot HDMI cable I am using.
Its unfortunately but no 4k60 for me.

I suspect it could be my cable because it does do a signal amplification but I thought any cable that could do HDMI 1.4 bandwidth was supposed to do hdmi 2.0 bandwidth..
Click to expand...

You are not going to be able to send a 4K@60Hz signal anywhere near 60 feet, no matter the cable until they release a HDMI cable that has a high end repeater that can handle full HDMI 2.0 bandwidth.
 
60hz at 4k has been enabled by Nvidia but not at 444, 420 I think. I thought there was no content to see at 444? I've been enjoying the titan at 60hz in 4k and I don't see any games that look better in 30hz at 444.

I have tried out several 4k's, Seiki, LG, Sammy, Sony, now I'm waiting to see if the Visio P is for me. Houck thanks for testing this.

Should be working in 444 on second generation maxwell hardware (gtx 980/970).
 
There are a couple of people saying that only one of the five hdmi ports is doing 2.0, and the others are still 1.4. So I would say try the port on the other end, maybe? The accusations of the hdmi not being 2.0 is rampant.

HDMI 5 is the 4K@60 port.

This is indeed correct and almost all of my testing has been using this port.

Also only HDMI 5 will do 1080p@120Hz as well. Of course the other ports still advertise the mode in EDID so you just get 'no signal' if you try to run that mode in one of the other ports.
 
I recently just picked a 55" P series and indeed it is a great TV. I'm using it right now as my PC monitor (along with a couple of GTX 980s in SLI) and while it works great, I seem to be unable to get the full 60HZ to work at 4K resolution. I've tried both the 344.11 and the 344.16 drivers and neither gives me this option. Anyone know if there is a option on the TV itself that must be enabled to run 4K at 60hz?

You've made sure to use HDMI 5? What does the Nvidia CP give you in the resolution drop-down?

I see you have 980 SLI listed in your signature. Are those the cards you are testing the 55" P series with?

Are you plugged into HDMI 5? Is that resolution available in the display options?

What cable are you using?
Click to expand...

I've tried two high-speed HDMI cables. One was the one that came with the PS4 and one was the one that came with the Xbox One. I've also ordered a couple of high speed cables from Amazon, I guess I'll see if it makes a difference once they arrive.
 
Cables are likely good, then. Have you trawled through the settings menu?

Also try making a custom resolution. If 60 hz doesn't work, try 59 hz.
 
The_Dark_Abyss said:
Yeah I tried the custom resolution and it doesn't work on anything above 30 hz.
Click to expand...

Wow, quite anti-climatic. Hopefully it is just a firmware or driver issue that can be easily resolved. Have you tried disabling the SLI on your 980's?
 
If the cables you have dont say 18gbps then they may not pass the 4k 60hz signal. Im no expert but just saying.
 
Regarding cable length, with my Samsung HU8550 the 25ft cable I got from Amazon worked at 4K/60Hz but it white dot artifacts were showing up on screen. Wasn't noticeable at first until I brought up an all black BG.

Moving down to a 15ft cable (same brand - Amazon Basic) eliminated this issue for me. So it seems longer cables may have issues passing an HDMI 2.0 signal... unless my 25ft cable was just defective.

Hmm this could be possible. Unfortunately neither cable lists the actual bandwidth it supports. I guess I'll have to wait for those two cables I ordered and see if that makes the difference
 
not to discourage but if you have to use $200 cables and sit with that poor ergonomics it doesn't sound appealing at all. kind of disappointing.
 
Well I have some 18gbps redmere cables i recently purchased from Monoprice so I will try them out when I get my 980's whenever amazon decides to ship my cards out. I just ordered the 70 P Vizio from Best Buy online with the 10% off coupon code and delivery is scheduled for this Saturday unless they change it. I will report back about how the set does with computer use and some gaming. I will however be sitting about 10 feet from the screen.
 
Have you tried non SLI? there have been known issues in the past where pixel clock is capped in SLI configurations.

The driver doesn't know or care about cable. If it reads EDID and thought it could do it the option would be there so there is something more going on. Even on linux it thinks I can do it and the mode is there but it just doesn't work.

I suspect SLI causing issues here.

I tried it with SLI and without, it still only allows 30hz in 4K. Hopefully this is strictly a driver issue and not an issue with the hardware on either end.
 
Pretty nice idea, let us know how it goes. Personally I'll wait for the Seiki future 4k monitors with displayport, or get a cheap used Panasonic AX800 somewhere. :D
 
Thanks for all the updates, guys.

Any luck with modding it through cru/nvidia's drivers?

Has anyone e-mailed nvidia/vizio about the issue (especially 4:4:4 for nvidia on top of 60hz)?

For the guy that asked why 4:4:4 is important: Video is encoded in 4:2:0, so (if they get that working, even on hdmi 1.4) 4k60 will look okay in that regard (because it's displaying what would be sent from the source anyway)...it should be fine at 4k30 too (but navigating the desktop will suck terribly at 30hz). When it comes to computer use (for static images and gaming) 4:2:2 and 4:2:0 looks more progressively like a blurry mess. 4:2:2 is livable in my opinion, 4:2:0 is not.

Keep at it guys.

These are very early days for both the cards and the tv...I am not surprised to see a slight clusterbang out of the gate, but I have faith we/they will figure it out, as this is likely to be a VERY popular setup. If nvidia doesn't step up and get 4k60 4:4:4 (or at least 4:2:2) working over 2.0, or vizio figure out what's wrong, some kind soul will hack something together...I'm sure of it.

(By the way, glad to see 4k->2560x1440 scaling in the nvidia control panel, I'mma guess that is only listed at 30hz, but it's a start).

By the way, has anyone seen both 55''/70 in person and have a comment on how they looked comparably? Kinda curious if the 65'' is still the way to go for quality/lag/viewing angle (given the 55/65 are usually a little better in those departments and typically fairly similar, granted slightly more expensive per inch). Kinda annoyed the 65'' is still (other than on Vizio's website) nowhere to be seen. I don't know if that's good or bad.

I would love a 65 ax900...if it ever comes out...and if it ever comes anywhere even remotely approaching these prices. 65'' (hopefully higher-quality, ie closer to 192hz like better LG models than 165hz like their lower-end models, ie 5-5.5ms rather than 6-6.5ms) ips with full-array (local dimming) and displayport. IPS (as far as contrast goes) may just be viable if that model is as any good.

It's a trickle-down, and I think these vizio models are a good place to hop on (assuming all the kinks get worked out) until that/oled/etc improve, add more features people like us would use (like vizio's low-lag mode), and prices come down.

I would never buy something like the 58'' ax800 (which is probably a crap innolux screen) as a computer monitor, even if the color is nice, but that's just me.

I actually don't feel CMI panels are 'crap'

The vizio after some calibration feels pretty good but sadly my seiki with its CMI is actually better for computer use/clarity IMHO.


Ok so I did some additional testing tonight.

No go with the $200 monster cable... same issue.

I tested to see if nvidia linux drivers were truly borked with the seiki as it is not picky on modes it will accept (and atleast *try* to display)... Well with the seiki I was able to push *well over HDMI 1.4 spec. I was able to push 48 Hz (425 Mhz pixel clock) and still get output (and it detected as 48 Hz, of course it ran through its scaler and looked like crap) but it shows the video card was outputting a signal (previous driver versions would not output once >: 340 Mhz pixel clock) and is well exceeding Hdmi 1.4 bandwidth (340 Mhz). Any higher and I got 'no support' on the display until I got up to 438 Mhz pixel clock and then once I went higher than that it went from 'no support' to 'no signal' but it didn't seem to be at a specific frequency (it wasn't exactly at 438 Mhz) and I suspect this is an issue with the seiki just completely rejecting the signal that is so far out of spec (50% over its regular max pixel clock)

I now am feeling stronger that the linux drivers are not broken and instead I am starting to suspect that the TV is borked (just like it wont take 1280x720p @ 120 Hz) even though that mode is in the TV.

I am wondering if anyone has yet got this Vizio working @ 60Hz yet at all? I have heard people on the samsung have got it working under windows but I don't think I actually saw anything for the vizio yet.
