Playing PC through 4k HDTV - possible?
Discussion
I built a HTPC for my friend, for his Steam games and backed up DVD/Blu-Rays.
All worked perfectly until he bought a 4k HDTV, he can no longer get the screen from the PC onto the TV (sound is there, so assume it's a resolution problem)
Would a new GPU card with 4k HDTV capabilities resolve this, assuming it can be resolved?
Cheers
ETA - This is via a HDMI cable

I would check the settings on the PC. Is it the primary or second screen? What is resolution and refresh rate set at on the p.c. etc.. If it's a second screen is it set to clone or extend desktop...
It is the primary screen. I did try to change the resolution and refresh rate on the GPU, but still nothing (and I tried booting in safe mode, and the picture comes up on the screen, but as soon as I try changing the GPU settings, the screen goes blank). I hear the sound on the TV, but not the picture. The GPU is three years old so was wondering if it needed a new one.I ask because I am thinking of upgraded to a 4k HDTV, but have a HTPC with over 30tb of stuff on the HDD's, and works perfectly with our standard HDTV (50" plasma)
Just to confirm, I run a 4K TV (LG EF950V) from a GeForce 960 GTX and it's fine at 4k resolution.
I'm wondering if the HDMI port you are using on the TV isn't full 2.0 spec, can you change the computer to output a lower rate signal, either set the resolution to 1920x1080, the colour to 4:2:0 or (as others have said) drop the refresh rate.
At 4k resolution you may not be able to do the full 60hz, 4:4:4 signal if the HDMI ports are only 1.4, what TV is it?

Thanks for that. I did tell him to change the HDMI cable. I am not sure what make/model the TV is, I just know it is a 4k LED TV. It worked fine with his previous plasma TV. I will have to try and get down to see him to check it all out again, and bring another monitor so I can change the refresh rate...
I would try a variety of HDMI leads, seen some HDMI adapters and leads play silly buggers with monitors and TVs
As said try a variety of screen resolutions and refresh rates, find one that works, then fine tune from there.
Before you try testing plug the PC into a monitor with the lead you are using if you can to ensure that a signal is actually coming out of the PC correctly!
Bit fiddly but with a bit of testing and swapping settings and leads it will work

Cheers, we tried the different HDMI leads. I have asked him to look at the HDMI inputs to see if there's one specific for PC.As said try a variety of screen resolutions and refresh rates, find one that works, then fine tune from there.

On a separate issue, I am seriously considering getting a 65" 4k HDTV to replace our 50" plasma. Are the wall brackets any different, or are the fixing points fairly universal?
Would like an OLED TV but damn they're expensive...

Yep - as the HDTV will be LCD and not Plasma it'll weigh a lot less so the bracket will still be fit for purpose.On a separate issue, I am seriously considering getting a 65" 4k HDTV to replace our 50" plasma. Are the wall brackets any different, or are the fixing points fairly universal?
