Cheapest GPU that does 4K @ 60Hz (for HTPC duties)

[Participant]

Hi all

I've got a 4K TV coming for the living room. The HTPC in there is currently an AMD 5xxx (can't remember which) that doesn't do 4K at 60Hz, so I'm just wondering if you fine people would be able to kindly recommend me a card that would please?

The HTPC might be used for very light gaming (the rest of the system is a Q6600 and 8GB of RAM), but the main consideration is media.

I also hear about 'chroma' - I don't really understand this but apparently 4:4:4 is important...do modern GPUs do this to? Does it need to be HDCP 2.2 compliant?

Many thanks.

I've got a rx 470 in mine which works very well. Not sure about the chroma, but it supports deep colour mode on the tv.

You can go as low as a gtx 950 just to display the image, assuming that your tv has hdmi 2.0 inputs.

Thanks. It's an LG OLED B6 so has HDMI 2.0. What about the newer 1050? Apparently that has HDMI 2.0b and it's only £100 so a bit cheaper than the 950.

As you can see its a bit of a mind field at the moment , if you want to "future poof".

There's also the rx460 which supports 4k hevc.256 via hdmi2.
Here's the whitepaper for polaris, i think page 15-17 will tell you about displays.

Basically under.hdmi2 you will be limited to 4:4:2 hdcp.

Sorry for lack of update. Went for a 1050 in the end; nice and small and low power, and not needed a 6 pin power connection.

Eek, some right shenanigans in those threads. Sounds like the gtx980 guy had the wrong gpu in the end!

Regards future proofing, all I want is for the hdmi connection from gpu to TV to handle 4k @ 60hz at whatever chroma and bit rate.

Thanks. I did some reading into the 460 vs 1050 and went for the 1050 (which also supports hevc) because I'll do a little 1080p gaming and it's faster than the 460.
