Glossy screens used to make look images brighter on LCD screens...
We've now moved onto LED and IPS, and various other acronyms.
Basically, now you don't need a glossy screen for picture quality.
Glossy screens reflect the light and make the images look a little brighter whereas matte screens absorb more. But since LED backlighting, and latterly IPS screens, the screens are bright enough on their own to avoid needing a glossy screens.
Look at the lg 22 inch IPS224v. I'd personally go the next size up and go for an Iiyama X2377HDS, or as many others use here, the Dell S2340L, or if you can push it, the Dell U2312HM (they're often on offer at a more reasonable price (£130ish))
We don't tend to just answer questions basically on here. We give better advice than that.
Glossy screens have been discontinued for a reason.
Get a nice IPS screen, and you won't be disappointed.
