Xbox One X will not work with supposedly compatible monitor

Xbox one X need last firmware

use Xbox one X bundle hdmi cable

HDMI Ultra Deep Color need "ON" , if monitor had and monitor setting "Customer"

Monitor "ON" then Xbox one X "ON", SETUP resolution for 4K...

I bought a LG 27UD69-W , I must HDMI Ultra Deep Color "ON" for 4K resolution...

anyway... try it?

I have the same issue. Can someone provide a solution? Thanks.

Any recommendations for good compatible gaming monitors that support Xbox One X's 120Hz with Freesync working simultaneously, preferably with a 1ms response time? I've been searching around and I've already purchased supposedly compatible monitors
that supported 120Hz and Freesync enabled over HDMI 2.0 recently and returned them for not actually working simultaneously-120Hz and Freesync with the XB1X. Seems the XB1X console is picky on which monitor it wants to work with. I did actually purchase and
returned recently the MSI Optix MPG27CQ 1440p gaming monitor with 144Hz and Freesync which was compatible(120Hz and Freesync) over HDMI 2.0 with the XB1X but had a defect in a color issue and I had to return. Any help for recommendations I can get to work
with this XB1X console to this date, I would greatly appreciate it, thanks?

Id stay away from 4k for comp it is not going to help as much as fps and refresh

It doesn't need to claim to be compatible, the monitor states it can do 4k all 4k monitors are compatible with ps5 and xbox series x. It's technology and science, backwards compatibility, the engineers even stated it worked fine on xbox series x, so they lied to me? There are even answers saying its compatible with The 4K portable monitor is compatible with Xbox series s, it states in the answers.

Even stated

Q: Would this work with nintendo switch and ps5?
A: Yes it works with any device with an HDMI port.

The reason it might not have stated this in description is the release of this monitor came out before ps5 and xbox S/X. All HDMI tv's are backwards compatible and future proof based on the capabilities of ther monitor, 4k thus 4k devices. I just know this monitor is being oversold as a true 4k monitor when clearly it's not, I believe the IPS screen is not 2160p just the electronics are perhaps set to 1800p, if the display is not a native 2160p then it's not 4k correct?

That meaning if it goes out of sync on occasion then it can't be a true 2160p display.

Hi SvendFJ,

From personal experience I prefer a TV over monitors for my console gaming, however, I hope this website helps which provides 15 of the best compatible monitors with Xbox one x and the refresh rate https://www.displayninja.com/best-gaming-monitor-for-ps4-pro-and-xbox-one-x/
