QN900B and 144 Hz

[Ulysses31]

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.

[Ulysses31]

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

Oh thats disappointing, thanks for the quick reply.

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