Radeon Graphics Cards To Support HDR Displays and FreeSync Over HDMI In 2016 (hothardware.com) 37

MojoKid writes: AMD's Radeon Technologies Group has announced a couple of new features for Radeon graphics support in 2016. FreeSync over HDMI support will be coming to all Radeons that currently support FreeSync. FreeSync over HDMI, however, will require new displays. The HDMI specification doesn't currently have support for variable refresh rates, but it does allow for vendor specific extensions. Radeon Technologies Group is using these vendor specific extensions to enable the technology. A number of FreeSync over HDMI compatible displays are slated to arrive early next year from brands including LG, Acer, and Samsung. The first notebook with FreeSync has also launched. Lenovo's Y700 gaming notebook is the first with a validated, FreeSync-compatible panel. The Radeon Technologies Group also announced that support for DisplayPort 1.3, HDMI 2.0a and HDR displays was coming in the 2016 pipeline as well. With current 8-bit panels, the range of colors, contrast, and brightness presented to users is only a fraction of what the human eye can see. When source material is properly mapped to an HDR panel, colors are more accurately displayed representing more closely what the human eye would see in the real world.

    First, NVIDIA comes out with their own implementation of variable refresh rates with G-SYNC, saying they'll never support AMD's approach. Then AMD digs their heels in, insisting that their support is more industry standard. Now, AMD is using "proprietary extensions" to enable it over HDMI, and you know that even if NVIDIA were secretly considering extending support to the AMD approach for DisplayPort, they sure as heck won't support AMD's extensions just to add support over HDMI.

  • When source material is properly mapped to an HDR panel, colors are more accurately displayed

    HDR = high dynamic range = difference of intensity between brightest and dimmest details, nothing to do with color. Well you could fuck with the colors to increase intensity because obviously you can only use 1/4 pixels in an RGBG pattern for red while you can use 4/4 for white, but I don't think anybody would make that trade-off. Rec. 2020 on the other hand will give you a wider color space and 10 bit color better accuracy, they're baked together in UHD broadcast/disc but HDR is just one part and not this

    • Brightness is important to color rendition. If you have a pure saturated red screen. But it's at 50 nits it's going to look like an unsaturated drab screen. Crank up that pure red screen to 5,000 nits and the color will be perceived as eye searing fire. If you can only ever reproduce a hue at 100 nits you're missing out on all colors which are very bright. Take a simple gradient: http://onlineteachingtoolkit.c... [onlineteac...oolkit.com]

      If your display could only handle the bottom half of the luminance you wouldn't be able

  • Extra bit depth is all very nice, but what I would really like from a new HDMI standard is faster, more stable syncing when switching resolutions and inputs. Any chance I'm more likely to see that with HDMI 2.0 devices than HDMI 1.3/1.4?

    Or is this something caused by HDCP that HDMI can't fix?

    • Nooooope. I have a Vizio UHD tv and apparently fullscreen Netflix actually changes your display settings and even through 2.0 when I maximize or minimize the Netflix window I lose input and sometimes the TV completely loses sync and says "no Input" until you change to a different HDMI and back. Sadly it seems to have gotten way worse.
