I'm buying a new monitor for a system using the video card "Intel HD Graphics 4400". (I'm thinking about buying this DELL S3422DW. I'm wondering how good of a monitor I can buy that will be decently supported by this video card.
I did a test using a large monitor and the video card seemed to display okay at a resolution of
3840 x 2160. However, I noticed the mouse seemed to have a delay. I don't own the monitor, so I can't easily test it again --- it didn't occur to me then to try to see if there was something wrong with the surface where I was sliding the mouse on. I did a second test using another mouse --- a wireless one and I did use a mousepad that's usually used by it --- and I saw the same delay.
I was wondering --- could it be that the mouse is drawn by the video card and somehow it is slow at those high resolutions? (Or was the optical mouse just in a bad surface for it?)
I have a 46" TV at home and the video card is able to get
1980 x 1080 on this TV. I don't see a delay in the mouse at all. (But could it happen at
3840 x 2160? Does that make sense? I have no idea.)
