XBX Series X - 1440p @120 hz issue onsamsung 27hg70q

Dang. That's a bummer. I tried turning of VRR and it don't help.

You might be right on the 100hz, as I was only able to select 99hz from windows display option when connected via HDMI as external display.

Hi, my name is Fernando and I am an independent consultant for Microsoft products.

Please try the following steps:

- From Home, navigate to Settings
- Then go to General > TV & Display options
- You’ll see a menu that shows Display, Setup and Advanced.
- Under Display, if your tv allows for it, click refresh rate in the drop down menu and change it from 60 Hz to 120 Hz. - Your system should automatically adjust
- You’ll receive a message if your tv does not support 4K with 120Hz, stating that the Xbox will revert to the highest resolution supported by your display that will allow for 120Hz refresh rate.
- You can then choose to keep those display options.

Or override you tv settings

- From Home, navigate to Settings
- Then go to General > TV & Display options
- You’ll see a menu that shows Display, Setup and Advanced.
- Navigate to Advanced > video fidelity & overscan > overrides
- In overrides, select HDMI and “use manual settings”

It does appear that the monitor only supports up to 100hz via HDMI. Just to be sure, have you tried it with VRR turned off?

Hi

I managed to address this.

Steps

1. On monitor settings turn of AMD free sync

2. Change the refresh rate from 144 to 120

3. On x box display settings unchek enable 4K

4. Change resolution to 1440p

5. Change refresh rate to 120Hz

Played Doom at 120 and it was awesome 😎.

I don’t think this is true. I plugged my series x into a gigabyte 1440p 165 hz monitor yesterday after my 4k Samsung qled backlight died. I think HDMI only supports up to 120hz (the monitor cable is required for 165 hz). Going through an HDMI switch, I cannot do 1440p 120 fps, but it has no issue doing 1080p 120hz. After I get an upgraded HDMI switch and a better HDMI cable today, I’ll see if that allows 1440p 120 fps.
