4K Screen Question using HDMI @ 1080p

Thesnipergecko · 17 Dec 2014 at 11:53

Hi all

I'm looking to get a new monitor and would like to go 4K.

I use my current screen for Work/Gaming and my PS4. I've seen on the specs of the 4K screens that over HDMI they only support 30Hz. I assume this is HDMI @ 4K?

If the PS4 is running at 1080p on a 4K screen will it support 60Hz or are the screens still locked to 30Hz at any resolution over HDMI?

Thanks in advance for any advice.

Don't accept this as concrete confirmation but when I played my PS4 on a 4K monitor I'm 99.99% sure it was 60hz.

I'd test it for you, but I don't have the monitor anymore.

How did it look?

Yeah, 4k screens can still do 60hz at 1080p over hdmi, it is just 4k@60hz that doesnt work (unless you use the nvidia chroma feature)

It looked fine. Not as good as my 1 inch smaller 1080p native screen, but I don't know whether that's due to larger screen size or not. I think if I hadn't been so used to my other screen I wouldn't even notice it at all.

So downscaling a 4k monitor looks okay?

Considering a 4k running at 2560x1440 for future-proofing.

It's upscaling not downscaling - the screen will take lower res and scale it up to 4k. How well it does this will vary by screen, 1080p to 4k presumably is easy being a straight multiple but I don't really know much about which ones do a good job or why.
