Hi i have just purchased an x box x and a 34inch curved monitor the monitor is 21:9 aspect...

Hi,

It's not possible on that display. The big reason why is that it isn't a 1440P display, at least it isn't a 16:9 aspect 1440P display, it's a 21:9 Ultra-wide monitor. Xbox only supports 1440P 16:9 aspect ratio displays. These monitors have a resolution of 2560 x 1440, yours has a resolution of 3440 x 1440.

The Asus ROG PG348Q is designed more for PC gaming not console gaming. Unless Microsoft provide support for these types of monitors in the future I'm afraid you're stuck with a maximum resolution of 1080P.

Hi,

Xbox Series X/S have issues with 1440P and 120Hz on various monitors due to many monitors using none standard timings. However, you have another issue in that your monitor is
not 1440P.

Xbox consoles don't support ultra wide monitor resolutions, this monitor is an ultra wide. The 1440P supported on Xbox consoles is in the 16:9 aspect ratio QHD (2560 x 1440), your monitor is a 21:9 aspect WQHD (3440 x 1440).

Therefore, realistically your maximum resolution when connected to an Xbox console could be limited to 1080P. It may be possible to select 2560 x 1440P, but it won't look right and it probably won't run at 120Hz.

Your display is HDR 400 rated, this is entry level HDR and in most cases it's mediocre, yours isn't great. It just can't get bright enough to fully show a true HDR effect. Experiment with it (ideally in dark room), you'll find SDR to be better.

Hi,

I'm sorry to tell you but for the moment at least you won't be able to use your monitor at that resolution. The reason being is that your monitor is not 1440P monitor. A true 1440P display has a 16:9 ratio and supports a resolution of
2560x1440.

Xbox One X consoles do not currently support 21:9 aspect ratio's, therefore unfortunately, there is no way to display that resolution natively on your Xbox One console.

The monitor you have is more is more for the PC gaming market, which supports Ultra Wide aspect ratio's and resolutions.

I'm really sorry about that.

Not being a programmer I can understand it would take some effort to have support for 21:9. That being said I just wish MS would just come out with a statement that Series X will or will not support 21:9 so people can move on to other monitor(s) purchases.

Would like a wide screen monitor 21:9. I wonder if Scarlet will support 21:9 aspect ration ????
