Strange issues with screen Resolution and Monitor Refresh rates on G9 49" LC49G5T

[ZebedeeBoss]

Ever since downloading and installing Nvidia driver 572.60 (Game or Studio)

My Samsung G9  LC49G5T has some strange issues.

When running 50/50 picture in picture 2560x1440 - you can only select 120Hz (as per spec)

Now on the monitor designated as "Main" in windows I can select 240Hz.  How?

Also using DSR2.25 settings you can normally run 2 x 4k screens

Now the "Main" screen says my native resolution in 50/50 Picture by Picture mode is 3840x1080?? How

Has anyone else experienced this? 

I need some help please from the Clever Boyz and Gurlz please.  Thanks in advance Zeb...

Not an expert on this, but maybe in the meantime, you could rollback the driver?

Hi, thanks for the reply, I was hoping not to have to do that as the 570 series of drivers allow access to DLSS 4. I guess that will be the ultimate option.

Thank You...

ps I guess I should have stated (in case it makes a difference) I am running an AMD 7800x3d paired with an RTX 4070
