QN900B and 144 Hz

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.

Hello,

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.

Best regards

Have you figured this out? I am having the same issue, I can only get 144hz when using resolution 3840x1600 even if the gamebar settings is set to 16:9 I cant go past 120hz at 3840x2160.  I have the same TV, hdmi 2.1 cables and I just cant figure this out? maybe false advertisement? also the set was purchased in the US.

Nope, I've accepted that 4K 120Hz is the max I'll get out of this thing even though ads paint a different picture.

I was speaking to a customer rep and it seems they themselves have no clue 🤷🏽‍♂️

I have the same issue with the qn900c 85”, latest firmware 1310.3, Nvidia 3090ti with latest drivers 546.17 , windows 11.  HDMI 2.1a 8K certified cable.

no 144hz @ 3840x2160. only with 3840x1600.  

I hope somebody can figure this out, I’ve been reading a ton of people with the same issue and not finding any resolutions.  Trying to make a custom resolution and refresh rate in the nvpanel but the option is greyed out.
