Issues with HDR streaming on your LG 65nano75upa TV display.
Issues with HDR streaming on your LG 65nano75upa TV display.
As the title states, I'm using an LG 65nano75upa TV, with an HDMI 2.1 to display port cable, into an Nvidia 3080ti gpu. Running an Intel i9-10850K cpu @ 3.60GHz, with 64 GB of RAM on a 64-bit Windows 11 Home edition OS. For the life of me I can't figure out how to get the option for G-Sync to show up in my Nvidia Control Center. My television has auto-updates enabled, and I've downloaded the latest driver. My GPU drivers are also up to date. Windows's System > Display > HDR says that "Play streaming HDR video" is "Not supported," even though "Use HDR" says "Supported." The "Use HDR" toggle only slides to "ON" if I'm viewing a Blu-ray disc, and my computer says that my display is not HDR certified. Is there any way to get my television recognized as HDR certified? Can I acquire the G-Sync option in my Nvidia Control Center? Is there a way to get my computer to recognize this connection as "Display Port" as opposed to "HDMI HDTV"?
You may need to change the TV settings to game mode for the g-sync feature to appear. This is the standard way my Samsung TV operates.
Thanks, but this is an LG, and as far as I can tell, the game mode doesn't do too much on this model. Black and white stabilization and some audio stuff that I don't need with my PC, since I'm using the integrated audio on my MSI MPG Z590 Gaming Force. Also seem to be having a problem with my blu-rays changing my visual settings and throwing my PC's refresh rate 23.98 hz, which is a problem because the point of getting all this stuff working is to get the TrueTheater HDR and Smoothing working, as I'm one of the few smooth brains that actually enjoys high frame rate interpolation (soap opera effect) on my movies. Seems like a few years ago it took an act of congress to turn that stuff off, and now I'm doing everything in my power to try and enable it, and am just spinning my wheels.
The ability to turn on HDR with Blu-rays gives us a helpful hint. It reduces to 24Hz, which is typical and actually beneficial. This adjustment lowers the bandwidth needed, making it possible for HDR to function properly since it usually demands more. HDMI isn’t really a substitute for DP in this context. If your TV can handle Gsync plus HDR at any resolution and refresh rate, the problem likely lies with the HDMI cable itself.
Just using an HDMI cable works well. It's important for your display to match the content's refresh rate for the best viewing. I agree, 24Hz is too low and causes issues like visible frames and poor immersion. A well-tuned interpolation with minimal artifacts is ideal. This doesn't alter my previous points. For optimal performance, your screen should sync with the game's FPS (typically 29.97Hz or 23.976Hz), allowing the TV to add frame interpolation. Also, you haven't checked if game mode was enabled.

I can't rely solely on an HDMI cable since the port on my 3080ti is dedicated to my Oculus Rift CV1. I understand your concern about the 23.98 hz setting, but my goal is to enable TrueTheater HDR and Smoothing in CyberLink's Power DVD 18. I thought the display needed to actually show higher quality to trigger the software’s smoothing, as the TV’s Motion Smoothing is turned off for PC. Also, yes, I confirmed I’m using game mode. It’s active and doesn’t appear to help with HDR activation or G-Sync, which isn’t supported by the RTINGS review I read about my model. I’m emphasizing that my main aim now is to figure out why HDR settings fluctuate and why it works for gaming but not for video streaming.
Please check the correct connection and locate the settings menu. I understand you were unsure about your monitor's G-Sync compatibility.
