Xbox One S does not recognize my Acer ED273UR monitor as 4K capable.

I use a high-speed HDMI to DisplayPort uni-directional converter cable (BolAAzul AHDPC) to connect the Xbox to an Acer ED273UR monitor. Xbox says the monitor is not capable of displaying 4k mode. The monitor specs say it is capable of 2560 x 1440 at 48 - 144Mhz refresh rate. What am I missing?

Xbox is current with updates.

Thanks for the answer. I didn't find the correct specs, obviously.

4K is 3840x2160

It's 1440p only

Hello, My name is Jesse. I'm an Independent Advisor and a member of the Microsoft community and I'd love to assist you today.

The Xbox One S is able to output at 120hz 1080p but no games will run above 60fps. The One S can recognize 120Hz displays but unless someone actually codes a game for the One S that can actually run at 120fps, that capability is almost useless.

Just like 4k resolution - the One S can recognize 4k displays and render Netflix videos at that resolution but not one single game is actually able to render at 4k.

You can play the Xbox One X on non 4K TV / Monitors,

However in my opinion, if you have no intentions of upgrading to 4K, its a waste of money to buy hardware that's capable of 4K gaming to not be gaming at 4K, even more so with the Xbox Series X arriving later this year,

The same can be said for those who buy an RTX 2080 Ti's ( a 4K, £1000+ ) card to only use it on 1080p Monitors for PC gaming,

I myself, if i didn't have a 4K TV and 4K Monitor, i would've just stayed with an Xbox One or at most a Xbox One S.

Hello Spinhead82,

Things are still in a state of change in the land of 4K UHD and haven't quite settled out yet. Part of this may have to do with DRM (Digital Rights Management) and trying to lock things down when it comes to all this 4K digital plumbing. Not only is it the
hardware, like needing to use HDMI 2.X cable. But, it's also the software. Does the firmware in the monitor/TV support the 4K UHD (HDCP 2.2)
content coming from the attached device ("Checking your TV's 4K and HDR capabilities on Xbox One S")? Yes, the Samsung U28E590D
can do 4K UHD, but does it support HDR10? HDR10 support seems to be a very important threshold when comes to connecting the Xbox One S to 4K UHD TVs. The current crop of 4K UHD monitors seems to be more directed to PC gamers. While, the Xbox One S is geared
more toward lager format TVs. I'm sure that this is not the only list, but Windows Central has what it calls "Best 4K HDR TVs For Xbox One S".

Good luck and good gaming,
