I got the QN900B to replace my Q950TS mainly because of the 4 HDMI 2.1 ports and other improvements.
Sometimes I use the QN900B as a monitor for PC gaming and was trying to get 144 Hz since it was advertised but it I can't get higher Hz than 120 on any supported resolution in Nvidia Control Panel.
I use it with a RTX 3090 TI in Windows 11 with an HDMI 2.1 certified cable.
Is there anything special that needs to be done first to get 144 Hz working on PC?
@Ulysses31: Please can you confirm the screen size of your QN900B, along with where you purchased it, and where you're currently based. While looking into this I found that the specifications for Motion Xcelerator Turbo Plus varied from region to region, with the UK model offering 4K@120Hz/8K@60Hz.
On the other hand, the model specifications on the Malaysian website mention the 144Hz option.
I bought the 75" model in Belgium (krefel.be).
The product page does mention 4K 144 Hz as a capability.
It came with FW 1302 out of the box.
