3440x1440 ultrawide support on Samsung Glaxy Book 3 Pro

[Sames2772]

Hello,

I am able to connect my Samsung Galaxy 3 Pro to my Ultrawide monitor (21:9) Samsung odyssey G8 Oled (cable is HDMI to Micro HDMI). 

However I can not change the output aspect ration and my pc can only output a 16:9 AR which is then stretched by the monitor.

I have downloaded the latest driver 32.0.101.5768 but still can't change it to get the 21:9 AR.

It says below  "This display has a fixed aspect ratio"

My work laptop (dell latitude) was working just fine so it is not a monitor or cable issue.

Can you please help ?

The HDMI port on your Samsung Galaxy Book3 Pro only corresponds to version 1.4

Please use a Thunderbolt 4 cable to connect the device to the Samsung Odyssey OLED G8 G85SB. This enables 3440 x 1440 @ 120 Hz via the DisplayPort HBR3 protocol.
