I bought an Odyssey G7 and received my Xbox Series S.
Apparently there is no HDR compatibility, because in the Xbox settings the HDR calibration tells me my screen is not compatible with HDR...
I've updated my G7 with the latest firmware (1009.3) but it doesn't change anything.
Is there a specific setting on the monitor ?
Unfortunately you can only get HDR on the Series S/X over a 4K signal. Im using the G7 with a Series X and can get HDR but only when i switch off freesync and have a 4k signal. So may not be possible on the Series S. This is not a monitor issue, its the xbox. Lets hope microsoft update this.
would be more brilliant to verify first the minimum requirements from Xbox Team as the error message suggests "screen is not compatible with HDR"
