Normally these are defined as TV resolutions in a CTA-861 extension block. Thanks for the reply Toasty, I appreciate it I see, I recall that I had something like this working before with this emulator, but I did a driver clean and the resolution is now gone. I have already cloned the EDID (hence it is appearing as an LG TV), but I can only select the HDMI 2.0 compliant resolutions. Also, I had created this through Nvidia Control Panel but I can't seem to recreate this anymore (as it always picks 4:2:0 without HDR, even for 2560x1440). I was then trying the cru tool to create this, but the resolutions don't show up in the Windows 10 resolution menu at all. Basically, I think it was sending a scaled HDR10 2560x1440 @ 90Hz signal to the emulator. I think this is fine, since the stream was still 4K HDR10 @ 90Hz. Summarizing my question, it's not possible to push 4K 120 HDR over HDMI 2.0 due to pixel clock limitations, but I am wondering if I can still stream this resolution. For that I need to be able to select this resolution from Windows regardless of the signal sent to the emulator. Not sure if my understanding is correct here though. Many thanks! |
