Waited and waited...and waited... for the new 4K Vizio P-series 4K sets to come out. Picked one up the day they hit Costco. A couple days later, a GTX 970 arrived. 4K, here I come! ...or not.... The Vizio P series will not support a 4:4:4 chroma @ 4K/60 hz. The Vizio tech (who was looking at exactly the same card I have) corresponding with Nvidia techs, has discovered that Nvidia doesn't support 4:2:2 over the HDMI connection, resulting in what may be a further degrading of color, to 4:2:0, resulting in very blurry text. 4K @ 60hz is not possible. 4K @ 30hz is virtually unusable. 1080 can be forced to a 120hz setting, but again resulting in blurry text. 2560X1600 can be forced to 60, and again, very blurry... disappointing.

Visio claims these to be HDMI 2.0. HDMI 2.0 will allow 4:4:4 at 60hz and your GTX 970 has an HDMI 2.0 output so.....

"Will allow" is the phrase of the day. "Will allow" doesn't mean "must allow" According the the 3500-post "official P-series owner's thread" (can't link that for some reason) at the AVS forums... the HDMI 2.0 and 4:4:4 is gimped, possibly due to HDCP 2.2. It seems the only sets that *might*allow 4:4:4 are a few of the LG sets, which have horrible display lag. I've tried for nearly two weeks, and dozens of hours with both Vizio and EVGA tech support, to get 4K/60. Isn't happening.

This has been very typical of 4k TV sellers. It's pretty disgusting how they are deliberately hiding information like this from consumers. Borders on Anti trust. AT&T got sued for pulling stuns like this back in the day. Sorry to hear it and I hope you get a refund.

It is disgusting, yes. I read your posts about the Samsung and UHD colors... how is it working for you? Blurry text? Considering swapping it out for one of those, if it's OK. EK_Derick

Actually mine looks very good and has no issues I am aware of. It may have the chroma sub sampling but I don't think so. Samsung support calling back. I'll know soon. They call it true 4k UHD though, so I'd hope not. I wouldn't expect your TV to ever support it though. I believe it is more of a hardware limitation than firmware, if you are not even seeing 4k res. I'd return it and get another one. Mine just has an issue where I switch HDMI ports and loose signal. I have to switch hdmi ports, make sure the port I switch to registers, then switch back to the one I want to be on, before it works. Sometimes I have to do that couple times. EXACTLY like that or it won't work.

Here's the results of attempting to get a 4k resolution @60hz. hmm.. it won't let me post it. A search on YT should pull it up. Title is "Vizio P series test 3840x2160 resolution. EVGA GTX970 graphics card "

Maybe his HDMI cable is bad, can't handle the bandwidth. Do they have hdmi 2.0 cables or is it the same?

There is no such thing as an "HMDI 2.0" cable. There is no "2.0" designation for cables. Anyone marketing an "HDMI 2.0" cable is lying. "High Speed" and "High Speed with Ethernet" are official designations, and are fully capable of HDMI 2.0's 18Gbps need to pass 4K @60hz. I've tried several different high speed cables.

I've tried several different high speed cables.
technically there is no HDMI 2.0 cable spec, but i believe you need a cable rated 18gb+ to get 4k @ 60hz. many cables, even $50 monsters, are only rated 10Gb (though i bet they might be able to to more. i will assume that, that alone could be the cause of many 60hz problems. if you have the option, purchase a cable that says 18gb on it just in case. i just bought a cable rated at 27Gbs for my P652ui-b2 (yes, a monster. but i saved a bunch getting it used), now all i need is a 970/980. i was also considering a 295x2, but first, it either needs a firmware update to dp1.3 (which will pass 4k 60hz from dp to hdmi using any adapter), or 2, the active adapters need to be released (converts dp 4k 60hz to hdmi 2.0 4k 60hz actively).

HDMI is a dying tech as well
saying its "dying" is hilariously over dramatic. but yes i agree, i wish more tv's included 1 or 2 DP 1.3 ports.

Sorry about your bad luck. The LG BU8500 will do 4:4:4 60hz. Get one of those. As for the input lag...its not horrible, but not good for competitive FPS...but if you are a competetive fps gamer, you are likely looking for 144hz with light-boost anyway, 4k 60hz is for the fully modded skyrim, not CSGO.
If you get 4k large format, I highly encourage you to play "The Vanishing of Ethan Carter" and be prepared to be blown away with how good a game can look on 4K.

I have a Vizio P502 and a GTX 970. 60Hz works with no issues. I'd happily do some tests with it if I got the time, but it definitely supports 60Hz @3840x2160.
