G-Sync over HDMI 2.1 uses the VRR feature of HDMI 2.1. G-Sync over HDMI 2.0 does not work with Nvidia GPUs. AMD has a proprietary solution to support VRR over HDMI 2.0. Thank you. What i thought. Does g sync on hdmi 2.1 still work if the port on my laptop is hdmi 2.0. No. HDMI 2.1 needs HDMI 2.1 support also from the computer. Best overall. AmazonBasics High-Speed HDMI Cable. SEE IT. AmazonBasics keeps it simple and cheap, which makes the brand’s HDMI cable hard to beat. Best HDMI 2.1. Zeskit Maya Ultra High Speed On ps5 you do need hdmi 2.1 for 1440p120hz. Ps5 still outputs a 4k120hz image and your tv/monitor will do the downscaling to 1440p. That is the only way to output 1440p on ps5. You need HDMI 2.1 to play at 120fps at 4K. HDMI 2.0 supports only 120fps at 1080p on PS5. And even when they do, the first generation of 8K TVs likely won’t be compatible, since the initial models hitting in 2019 will probably have incomplete HDMI 2.1 support. Plus, HDMI 2.0 is Huh, haven't really heard about DP being a hassle myself. Anyway, DP having a bandwidth lead rarely matters. For most applications HDMI 2.1 has more than enough bandwidth. Even HDMI 2.0 is enough for most use cases until 8K ends up being common. And then we need a new HDMI update anyway, as HDMI 2.1 can't do 8K60 without compression. Afaik it supports 4K/120fps, thats ~8.4m pixels, versus the ~4.9m on the 3440x1440, which leaves enough bandwith for reaching 144hz, that's for sure. [deleted] • 2 yr. ago. depends on the bandwidth the machine puts through the HDMI port. HDMI 2.1 supports "up to 48gbs". Example, Lenovo legion has HDMI 2.1, the HDMI output has 38Gbps and then An rtx 3080 has an hdmi 2.1 port so you're all set as long as the LG c1 has hdmi 2.1 in port. People are wrong about hdmi 2.0 maximum refresh and resolution though. Hdmi 2.0 can do 4k/120 with reduced colour data of 4:2:0 instead of the full colour 4:4:4. For 4k at 120hz. 3840x2160 x 120hz = 995,328,000 pixels. 10K at 120hz is 5.3 times more pixels per second than 4k at 120hz. Even 4k at 240Hz gives us 1,990,656,000 pixels per second which is 2.67 times less than 10K at 120fps. Therefore, why doesn’t HDMI 2.1 version allow 4k at 240hz or 8k at above 120hz? mt5YM.

does hdmi 2.0 work with 2.1
