Hello,

I have a problem with my Odyssey G9 (LC49G95TSSUXEN). When I turn on the 240 Hz the image quality goes really bad, I can see "horizontal pixel stripes", like layers on wood, I don't really know how to describe it. With 120 Hz I don't see this problem, everything is smooth. Does anyone know how to fix this or should I wait for a new Firmware?

My current firmware: ver1010.2

GPU: RTX 3080 (465.89 driver)

The following is from the Nvidia RTX 3080 spec sheet.

To start with,  is your computer a PCIE Gen 4 with a Intel I9-10900k or equiivalent CPU capable of supplying 320 watts to the GPU from a minimum 750w PSU?  A PCIE Gen 3 and or lesser CPU will hobble the 3080.

The card can do this when fully supported by the computer:

1 - Up to 4k 12-bit HDR at 240Hz with DP1.4a+DSC. Up to 8k 12-bit HDR at 60Hz with DP 1.4a+DSC or HDMI2.1+DSC. With dual DP1.4a+DSC, up to 8K HDR at 120Hz

2 - Supports 4K 120Hz HDR, 8K 60Hz HDR and Variable Refresh Rate as specified in HDMI 2.1

Now, where were we?  Are you using the DP 1.4 cable supplied with the monitor?  Proper cables are critical to high bandwidth signaling.

You would actually need to reach out to Samsung in your area seeing as this isn't a US model and we can only help with US models. http://www.samsung.com/visitcountry
