It's OK with me if you've got expertise; thanks for letting me know. (And, it will alter my approach.)
Did the people who put the packaging together at Acer have the sense to provide a disk with a driver? (I presume not, or you wouldn't be asking me.)
Acer's USA-region site lists no such model of monitor! so I have to ask, to cover all the bases for myself, Are you in some other region than North America, please?
CNET Download.com has a driver for this model listed (if you trust them, and I'm only about 85 % sure about CNET Download.com myself) athttp://download.cnet.com/Acer-LCD-Monitor-X223W/3000-2108_4-196037.html
Is the white text on black background, distinctly fuzzy-edged when looked at quite closely? (as opposed to being spread out at a large size and thus with less resolution.) If that's how it looks, and if it looks that way even at high resolution settings, then I would say the monitor has an off focus voltage - or other electronic problem.
(Does it have any internal menu? internal settings? if so, does the text of those look more fuzzy than you'd expect [and I'd expect some, for sure, the resolution is always low on those internal menus] ? Since those are internally generated, they are a good way of determining display focus quality independently of computer software or video card performance.)
