TV & scaling on GPU woes

[chenw]

Hey all,

Last night I tried hooking up a GTX 950 to a 4k TV (LG 49UH611T) via its HDMI, and the results were pretty bad, EG For some reason I could not get the GPU to output at 4:4:4 chroma at 4k/60hz, and TV scaling is AWFUL, so I tried scaling on the GPU, which looked much better, except for one issue: the refresh rate is locked at 30hz, even if I dropped the resolution down to 1440p or 1080p.

I am using Win 7 Ult with all of the updates, as well as using the latest nVidia drivers, I am curious if this is by design or if there is a possible workaround to get the scaling done on the GPU as well as retaining 60hz? I never had this problem on a desktop monitor, only via the TV for some reason.

Thanks!

you do support 4K 60Hz.

Not sure if this will help: https://www.youtube.com/watch?v=zsLs0TMfFws

(interface is probably still the same)

also, there is a "1440p" option? I didn't know that... is it only available if you scale via the NVidia GPU?

*If you choose to scale by NVidia GPU then make sure "ASPECT" is also enabled.
