Noticing some people are still having issues with this, so here are a few things I found with my troubleshooting on the Samsung Odyssey G9 with FW version 1013.
Setup
DP1: Windows PC, RTX3090 with 5m DisplayPort cable
DP2: Macbook with M1 Pro - OWC Thunderbolt 4 Hub - CableDeconn 8K USB-C to DisplayPort 1.4, 1.2m.
Game
- Black Equaliser 14
Picture
- RPG
- Brightness 100
- Contrast 80
- Sharpness 76
With the M1 I got the flickering to go away by changing both the calibration and the monitor's contrast settings, I noticed at certain points between 67 and 75 the screen would flicker, so I currently have it set at 80 on RPG mode when using the MacBook, all other picture settings are defaults.
Now.. Game settings... Black Equaliser does not work above 14 on my MacBook, 14 results in no flicker, where 15 and above results in flickering and diagonal pin striping depending on what is showing, where it is and what is the contrast between it and the window behind it.
Garbage with Excel open and Teams chat Windows in front, so set to 14 and so far so good.
One other thing I noticed, I tended to find that the picture settings I like to use for the Macbook do not look right with the Windows PC, Game settings are ok, but picture must be changed, and changed back, the monitor does not hold settings per input, an oversight by Samsung, no doubt.
So if I change to sRGB (Which looks right to me for Win10) and then switch back to the Macbook, I get an instant flicker throughout the contrast range and need to change it back to my custom setting which is based on RPG with a couple of changes to the it away from the 67-70 Contrast range and a bit more brightness.
