The current HDMI revision supported by Xbox One X right now, HDMI 2.0, supports transfer rates up to 18 Gigabits per second – imposing a limit of 4K (3,840 × 2,160 pixels) resolution at 60 Hz HDMI is a cable connection used to deliver visual and audio information to screens. HDMI cables can also be used as pass-through connections, to hook-up amplifier surround sound systems to your TV. HDMI 1.1 was the original version, made specifically for DVD playback. The next real big jump was version 1.4, where 3D support and audio return was If your TV supports it the Xbox could go into a HDMI 2.0 socket which would allow the Xbox to do 1440p at 120hz or 4k at 60hz. You don’t need to buy new TV just for few features. HDMI 2.1 provides higher bandwidth and support of 4K 120hz. If any AAA game will ever manage to use that. The manufacturer added HDMI 2.1 support for its latest revision, delivering the best of 4K HDR content. Whether on Xbox One today or readying for Xbox Series X, the LG C9 and B9 provide unrivaled my tv is connected with an hdmi 2.0 cable but still says that hdr is not supported. it still works on my ps4 pro and all. i tried "forcing hdr" on my tv settings but when i do it doesnt detect any signals. i tried restarting my pc after that but nothing changed. every drivers is up to date. At this year's NAB several manufacturers confirmed that HDMI 2.0 will enable content up to UHD (2160p resolution) at 60 frames per second with 10-bit or maybe even 12-bit color. The current HDMI 1.4 specification tops out at 4K with 24 or 30 frames per second at 8-bit color. Increasing the specification that far means that test and measurement Which is why we thought you’d want to know that 4K 120Hz is already doable with HDMI. Another important “but” is that HDMI 2.0 doesn’t officially support 4K at over 60Hz, only HDMI 2.1 does. Experimenting and trying to force 120Hz won’t hurt anything or invalidate warranties, but it may not work. A lot of it will also depend on the It turns out. HDR will only enable if your Graphics Card or Motherboard has HDMI 2.0 or newer that supports HDR10. If you're using DisplayPort to HDMI 2.0 Adapter. It won't enable HDR10. Because, the Adapter use DisplayPort 1.2. Which means DisplayPort 1.2 does not support HDR10. Only DisplayPort 1.4 or newer support HDR10. You are correct that the native HDMI support is HDMI 1.4 only. I was presuming that @NicB has a motherboard that utilizes a LSPcon IC to convert from DP 1.2 to HDMI 2.0. This is possible considering that Intel's DP 1.2 implementation does include enough DP 1.4 capabilities to support the LSPcon IC converting to a full HDMI 2.0 or even HDMI 2.0a On the HDMI side, 10bpc requires 4:2:2 or 4:2:0 chroma sub sampling. On the DisplayPort side, with only two lanes, 10bpc requires DSC, or HBR2 4:2:0 (< 576MHz), or HBR3 4:2:2. But you said refresh rate 120 which means you are probably using a lower resolution such as 1440p or 1080p. 1440p120 = 483 - 497MHz. 6f1b.
