It's perfectly passable for most operations, but might fall short with HGiG in game tuning at some point in the future. I also did a few tests in different games comparing 8bit dithered HDR to native 10bit HDR, and I honestly didn't notice much difference. Theoretically, Nvidia could update the drivers to force one system over the other on a given port, but from their business perspective there is no incentive to do this. The other thing about GSync is that this deal with it not working with adapters isn't actually a hardware restriction - GSync uses different protocols for DP and HDMI.

Ctrl+Shift+F2 = + HDR RGB 4-4-4 8bit + GSync - using the native HDMI 2.0 to a 5 port HDMI switch for my older legacy devices connected to HDMI Input 4 on my TV.Ī quick tap and I can seamlessly change back and forth between daily usage mode, and gaming mode.

Ctrl+Shift+F1 = + HDR / RGB 4-4-4 10bit - using DisplayPort USB C to HDMI 2.1 adapter on HDMI Input 1 on my TV.

What I ended up doing was leaving the legacy HDMI 2.0 connected as well, then I used the software UltraMon to make hotkey profiles: The thing with GSync is you only need it for gaming.

The difference was night and day for me for regular Windows usage - everything was much crisper and more rich in colour. I bought the CableMatters DP USB-C to HDMI 2.1 adapter and this provides RGB 444 + HDR 10Bit using the full 40GBps of my LG CX, but sans GSync. This has been my preferred setup for gaming. There is no remaining bandwidth for HDR with this setup, and the 1/4 colour data loss is quite noticeable to me.Īlso available on HDMI 2.0 is RGB 444 8bit + HDR using dithering + GSync. And it has changed the scene drastically.

Yes, the native HDMI 2.0b on my system gives GSync support running, but as mentioned it's 4-2-0 chroma subsampled. It all changed in 2016 when the news broke about USB-C cables can output to HDMI directly without the dongle or adapter.

I have a 2070 and I went down this path, but I'd like to chime in on a few things:
