Can Xbox One be used with a 1920x1200 resolution monitor?

According to the manual, the Dell E248WFP supports 480i/ 480p/ 576i/ 576p/ 720p/ 1080i/ 1080p. Of those, only 720P and 1080P would likely be selectable on the console. 1920x1200 is not a resolution supported by Xbox consoles and thus the image would be stretched, reducing the image quality considerably.

I'm not able to determine how old this monitor is, but by the looks of it it's at least 10 years+ judging by the fact that it only supports VGA and DVI. While you can buy a HDMI to DVI adaptor (and it needs to be that way around), DVI does not support audio and this monitor has no speakers so a audio splitter would be needed, plus a set of speakers or headphones.

To be perfectly honest, you're better off just getting a new TV.

The Xbox has no way to communicate with it to determine that. This monitor is 15 years old, and does not support even the full DVI spec, it’s limited to single link DVI, see page 5 connector layout.

They are correct that you should buy a TV. Even the cheapest TVs today have better performance than pretty good ones from 2008

Your monitor only supports 1900x1200 resolution according to the manual. All monitors are required to support 640x480 as a default if a supported resolution is not available

Xbox supports standard VESA resolutions, which does not include 1900x1200

1280x720

1920x1080

3840x2160

Would be the most common

The One provides a max. resoltion of 1080p which means there are a true 1920 pixels in width and 1080 pixels in height. Usually a pc monitor which provides a resolution of 1920x1200 should be able to provide that, too.

"No, it's not. There is no "HDMI v1.4 cable". Never has been. It's not my problem if you can't be bothered to use the correct term."

Sorry, that you are OCD over the smallest issues... Is HDMI High Speed with Ethernet better then..?? You make a big deal over nothing... I'll just stick with the original HDMI v1.4 label thanks (i.e. HDMI High Speed with Ethernet)..

You are soo bloody annoying, IceStorm III... A Max Video Graphic Array resolution is 1024×600...

The Widescreen Ultra Extended Graphics Array (WUXGA) resolution is 1920x1200...

It's funny, that a person with an Xbox.com AV Icon, thinks VGA is 1920x1200..
