Xbox one X and 1080p monitor -both say its outputting 1440p?

Heya

I have a iiyama G2530HSU (nice little cheap monitor) and have been playing with the settings. It allows freesync so while messing I turned it off. Then in the X1X display menu I disabled auto detect for the output which brought up the usual drop down menu
-720p/1080p.

However, what is curious is it also gave me the option of 1440p (as well as opening up 4K options although I cannot use those obviously). So I thought huh ok and selected it.

On the monitor under information it usually says 1920-1080 @ 60HZ for HD. With 1440p enabled it switches to 2560-1440@60HZ so both the xbox and monitor are saying its 1440p native.

This should not be possible. It is a supposedly HD monitor so what is going on? Is it just tricking the monitor into thinking its a 1440p monitor? I was under the impression the 1440p option was ONLY available when connected to a 1440P screen? (infact
on my other monitor for work, A Asus, it does not give this option no matter what I change)

2 things: either its just outputting at that and for some reason the monitor thinks its now a 1440p monitor (note it CANNOT do freesync with this resolution on HDMI) or someone put in its older brothers panel in the factory by mistake.

I have tried to test it with Battlefield 1..which looks great supersampled anyway but that makes it tough to really see..it does seem nicer in 1440p but that could be a trick of the eye's. 1080p games seem a little sharper too in this mode yet again though
it could just be my eyes playing tricks as I'm expecting a difference.

Or have I missed something and this is a option regardless of the screen? Which still wouldn't explain why the monitor says its 2560/1440p :/

1080 HD

To be honest, I'm not all that surprised it's below 1080p for the console, but it will still be upscaled (better than, say, outputting 720p on a 1080p monitor on a PC with no upscaling) and has custom tailored AA, so I have no doubt it'll look great on both
consoles.

 

Monitor flicker on 1080p

The monitor I have flickers on certain things when outputted at 1080p. The monitor I have is an Asus ve258q. 1920x1080 res. When I output at 720p there is barely any flicker that is noticeable. Its kind of hard to explain but basically I can still see the
image fine but its just flickering quite bit in certain spots. When I set optimal resolution in the xbox settings it goes to 1080p. What should I do?

 

Interesting experiment, probably the video chipset of the monitor is 1440p capable but the screen has not enough resolution to support it.

 

A possibility they are more budget ranged monitors so maybe the use the same firmware/chips across the range but then I'd of thought it would also think it's 4K as they do those too.

Very confusing
