2020 Odyssey G9 G-sync not working at 240Hz

Samsung Advertises the 2020 Odyssey G9 (LC49G95TSSNXZA) as G-sync compatible but it is only working with G-sync on 120Hz, not on 240 Hz.

 

I have a RTX 2080 ti, Monitor running firmware 1005.4 (latest), connected with included DP cable and Nvidia driver 452.06.

 

Nvidia claims to support G-sync up to 240 hz on Driver 452.06 or newer - https://www.nvidia.com/en-us/geforce/products/g-sync-monitors/specs/

 

The monitor only works with G-sync in the 120 hz mode. In the 240Hz mode, G-sync is selectable but it's not actually functioning in game or the pendulum demo as tested by the Nvidia G-syn indicator or the monitor's OSD reported refresh rate (stays locked at 240Hz)

 

Samsung, is there a fix coming for this?? Otherwise the monitor shouldn't be advertised as G-sync compatible, let alone have the label on the product and the box...

On the Swedish Samsung-page for the Odyssey G9 it has a note saying that in order for 240 Hz G-sync to work you need a graphics card that will be released soon (which probably means nVidia RTX 3080 or similar). Until then the recommended setting is 5120x1440 @ 120 Hz for G-sync to work.

 

You can probably use google translate:

The issue is DSC.  2000 series and 3000 series cards are the only ones that can do 240hz @ 5120x1400 

3000 series currently has a bug where its not working. 

I have g9 and 3090.

Does anyone know why I can't set 240Hz without G-Sync 5120x1440 on Titan V through DP?
Card does not support this refresh rate?

only nvidia 20 series can suppot 5120x1440@240hz, because 10 series not have Display Stream Compression (DSC)

Yep, we hope they fix 240Hz G-sync ON asap, if possible of course.
