    Default Ultra HD 4K Linux Graphics Card Testing

    Phoronix: Ultra HD 4K Linux Graphics Card Testing

    If you've been eyeing a purchase of a 4K "Ultra HD" TV this holiday season and will be connecting it to a Linux system, here's the information that you need to know for getting started and some performance benchmarks to set the expectations for what you can expect. This article has a number of AMD Radeon and NVIDIA GeForce benchmarks when running various Linux OpenGL workloads at a resolution of 3840 x 2160.

    The 120Hz
    Although Amazon lists this as 120Hz, I am fairly sure when running at 4k, this monitor can only do 30hz...

    "till, there are a couple of key caveats here. DO NOT buy this TV for gaming. While Amazon lists its hz rate at 120, this is not true for 4K. This display can only output 4K at 30hz which is not zippy enough for most games, but it should be fine for movies. "

    Is there ANY consumer-grade 4K tv that can output 120hz right now ? Does the 20k$ samsung 84" does it ? I seriously doubt it.

    Can you even output 4K 120Hz with DP?

    Default Would be very interesting to see

    How well this works with most popular GUI managers like Gnome 2, 3, KDE, etc, and if there is any improvement when it comes to video.

    Yes, with DP it should work.

    The only issue to report on the AMD side with the Catalyst Linux driver was small white artifacts appearing
    Pic or it didn't happen

    Also, the dividers in the hardware chart for "display driver" and "opengl" are not showing for me. I'm not sure if this is a monitor/browser/website issue. Anyone else experience this?

    Judging by the Unigine benchmarks, it looks like 4K will be giving Nvidia and AMD new reasons to innovate and improve graphics cards both in hardware and software.

    It'd be very interesting to have a look at screenshots of Unigine Heaven or Valley, to get an idea of how current 3D generally looks on 4k.
