As I went to bed to fall asleep after an 18-hour working day, I read a Story on TechPowerUp from the German generation site Heise.de, according to which AMD Radeon graphics cards had limited HDR capabilities …Well, click bait can be bad, and now we know the truth.
The original story can be read here, which stated that Radeon graphics cards reduced color intensity to 8 bits according to mobile (16.7 million colors) or 32 bits, if the demo was connected to HDMI 2.0 and not DisplayPort 1.2, anything that piqued my interest.
10 bits consistent with mobile (1.07 billion colors) is much more consistent with the height of HDR TVs, however, the original article gave the impression that it was a limitation of AMD, not that of HDMI 2.0 and its inherent limitations.Heise.de stated that AMD GPUs reduce the output sampling of “full YCrBr color scanning four: four: four: four desired in four: 2: 2 or four: 2: 2: 0 (color subsampling /chroma subsampling), when the display is connected via HDMI 2.0 The publication also suspects that the limitation is widespread on all AMD ‘Polaris’ GPUs, adding the ones that drive game consoles like the PSfour Pro,” TPU reports.
I contacted AMD for clarification, along with Antal Tungler, the senior director of global generation marketing, who said it was an HDMI bandwidth limitation.Tungler stated that “we have no challenge to do the 4:4:4:10b/c HDR 4K60Hz on Displayport because it gives more bandwidth.”
Tungler added: “Four: four: four 10b/c – four K60Hz is not imaginable via HDMI, however, it is imaginable and we help through Displayport.Now, via HDMI, we make four: 2:2 12b of four K60Hz with which Dolthrough Vision TVs are made up, and we make four: four: four 8b 4 K60 Hz, which TVs can also accept as input.So we help all modes adapt through TVs.In fact, you can transfer between those modes in our settings.”
Now it’s settled. This is not a limitation of the Radeon amD graphics cards or the PSfour Pro’s internal APU, but a bandwidth limitation compared to the HDMI 2.0 standard.DP 1.2 has no challenge to launch HDR on the right four: four: four 10b/c to fourK60, with AMD compatible with everything, as long as you be careful when buying your TV or screen and need the most productive fun, HDMI 2.0 is a limitation right now.
Clickable bait pieces are not smart and tarnish other people’s reputations along the way. TPU ran the story without verifying it either, and I don’t personally call Heise.de or TPU personally, it would be great not to have sensational headlines at all that has been explained in detail (the limitations of HDMI 2.0 and the superiority of DisplayPort).
DisplayPort offers more bandwidth and will drive 4K120 in 2017, as well as 1080p and 1440p at 240Hz.AMD is at the forefront of technology, but it doesn’t fall into the exaggeration of this story.
