Windows 10: Windows 10 loosening internet at 60hz but not 30hz

I have a skytech pc and it is hooked up to a 55inch Roku tv at its native resolution and lately I’ve been having issues where whenever I go and switch my refresh rate from 30hz to 60hz and launch a game at full screen and change the resolution of the game to fit 1920x1080 it disconnects my wireless internet but when I quit and go back to desktop it connects fine idk why this is happening but it’s beginning to be ridiculous and annoying it has worked fine before and now it’s just like “no”. Today I was playing war thunder and I had my refresh rate on my pc set to 60hz and the game at 1920x1080

:)

 

Can't change refresh rate to 60hz cuz Windows only shows 30hz

Connected my monitor (Samsung UH750) over HDMI 2.1 to my PC (750 TI with no DisplayPort) and it is stuck at 30hz even though the monitor has 60hz. The HDMI 2.0 cable supports 4k & 60hz also the monitors HDMI outputs support 60hz. Still Windows only shows
30hz or below (Windows 10) I also have installed latest drivers. Any help is welcome.

 

HDR and WCG will not turn on for 4k 60hz, only 30hz.

Hi UmeedMalik,

Issue like this might be due to an outdated videocard driver. I'd like to get more information regarding this so we could further check and provide a more established workaround. Please answer the following:

1. What is the current build and version of your Windows 10?
2. Is this the first time that you are trying to connect your PC to your TV?
3. What type of cable did you use to connect your computer to your TV?

In the meantime, try the following suggestions to isolate the issue:

• Download and install all the suggested Windows cumulative and security update.
• Install the latest video card driver. Download it directly from the manufacturer's website.
• Use a different HDMI cable. Check if your video cable supports 4k 60hz resolution. Some HDMI cable only supports 30hz at 4k.
• Try connecting your PC to you TV alone. This will help us eliminate hardware conflict issues.

If you would like me to provide additional advice, simply respond to this thread. I will get notified and I’ll reply to you as soon as I can.

 

HDR and WCG will not turn on for 4k 60hz, only 30hz.

Hi there,

I have a gtx 1080ti and a Sony x900e tv. Both support HDR10. However if I set the the refresh rate to 4k @ 60hz via the Nvidia Control Panel Windows 10 won't enable HDR.

If I set it to 30hz, Windows 10 will enable HDR.

My TV is confirmed to be compatible at 4k 60hz HDR while Enhanced Format is enabled.

my set up is 3 monitors (2 24" samsung monitors, and 1 Sony tv which is the main display).

It does work at 1080p @ 60hz for HDR though.

Can anyone help? Thanks!
