4K TV with DisplayPort?

[zzzg]

Does anyone know of a 4K (UHD) TV (at least 30") with DisplayPort input(s) for less than $1,500?

1) Do you really mean a TV? I ask because 30" is an odd number to mention for a 4K HDTV.

2) If you do mean HDTV then how far back would you be sitting?

*Arguably you need to be closer than 1.5X the viewing angle (closer than 6 feet on a 48"/4foot HDTV) or you won't benefit from 4K.

3) The new GTX970 graphics cards have HDMI version 2 outputs that support 4K res. Is that an option?

Other:
I doubt you'll find what you're looking for. Also keep in mind that if the HDMI inputs are only 1.4 (which I saw on many 4K HDTV's) they only support 4K at 30FPS. You need HDMI 2.0 support for 4K at 60FPS.

So to be clear, HDMI might be your only option and again the HDTV must have an input that is HDMI 2.0.

(If a 4K HDTV had a Displayport input then that would be a "PC INPUT" which would go to a scaler like on a regular monitor so then you could choose your resolution as desired in a game. These PC inputs seem to have disappeared in favor of using HDMI. Also, if you hookup a computer and set to 3840x2160 via HDMI 2.0 you'll have to go back to 1080p on the HDTV settings to run a game at that res. You can't use an HDTV's HDMI input like a normal desktop and casually switch the resolution on the fly.)

Update:
Displayport does support 4K but only if the graphics card and monitor/TV support it at that resolution.

I think I smell what you're steppin' in... You want to use a luscious UHD Television not only as your TV, but also as your computer monitor. I want the same thing. I won't consider a connection that can't deliver 60Hz screen refresh however. Anything slower gives me a headache. You've already learned above theat HDMI 2.0 can do 60Hz, but HDMI is long in the tooth. What you really want is a UHD with a DisplayPort! The only UHD TV manufacturer that wants our PC business is Panasonic. Their TC-65AX900U television is the only one I've found that has a DisplayPort input, but it retails for $5500. The spec sheets from Panasonic's lower priced lines do mention at least one, "HDMI (4K 60 Input)", which I interpret as HDMI 2.0.

I think Panasonic makes a mighty fine UHD television IMHO, but they are not well destributed, and they are also proud of them when it comes to pricing.

It's hard to find info from the manufacturers about which HDMI standard revision their ports use. I guess they are all lazy when it comes to the details like that when most of their customers couldn't care less, but they have to know, or at least need to know that there are an awful lot us out here that do know what interface standards are, and really want to be reassured that their products are going to work the way we expect them to in our more imaginative configurations.

LG 31MU97-b is a 31", 4096 x 2160 monitor that's attractive at around $1400 as of today.
BenQ's BL3201PH is the best priced at $1000, and you can find openbox and refurbs for less.
But I want a television sized screen -- 60" or 65" -- because at my orangutan-like arm length, I can't resolve the pixel structure if I place the screen at the back edge of a 30" deep desk and with the keyboard drawer extended, my eyeballs are 4.0 to 4.5 feet from the screen. And when I'm done with the computing, I can switch inputs to the cable box or streaming source and enjoy the couch behind my desk chair.

rustlep,
old post.

Having said that, if he was gaming I'd be mentioning (for NVidia) the Acer Predator (IPS, GSYNC, 4ms, 1440p, 144Hz). It's only 27" but is a GSYNC monitor which is really what you want.

It's also 2560x1440, but then it's also 144Hz (and GSYNC works between 30Hz and 144Hz for this monitor).

4K is also problematic for desktop scaling and can't currently go above 60Hz so when you look at all factors, the Acer Predator is the best choice for gaming.

AND... as I said above you do NOT want to attach a 4K HDTV usually to a computer. You don't know how much video processing is being done (lag) unless it specifically has a gaming mode, and you can't easily change resolution in a game. Not even a 2560x1440 option that I know of. Just 1080p then a jump to 4K.

Anyway, 4K 30" HDTV's will probably happen at some point but likely a long time.

pb,

I just realized I forgot to mention that I'm not a gamer. A serious omission on my part, especially since this is a gamer leaning website. I'm a photographer/videographer who's interested in high resolution technology solutions because obviously, I want to see as much of my imagery on the screen at a time as I can get. My work doesn't suffer if an image reaches the screen a couple of milliseconds slower than the ideal, however I do want a minimum of 60Hz refresh rate, like I'm getting on my current tired setup. I haven't found any forums involving ultra high resolution discussions in the photography sites. Maybe it'll be up to me to get something going over there.

Hi,
Start your own post, but basically the short answer is you want a good computer MONITOR not an HDTV.

You'll need not only a 4K monitor for high-res quality but an IPS or similar panel (not TN) and if you go 4K you also need:

a) mouse that can handle that (i.e. 2000dpi or higher roughly), and
b) VIDEO card or integrated video that supports 4K@60FPS.
