I am looking for a 27" or 28" monitor to replace my 22" HP 2207. The reason is mainly to take the advantage of 1080p ,possibly for some xbox360/ps3 games(although I own neither now) and to have a biggest-possible monitor on my desk. I have done some research and now need certain information to make my chioce, as following: 1. What's the difference between 1920x1080 and 1920x1200? please don't tell me the latter has more pixels, I want something in depth. 2. I have looked up three displays : HP 2709m, Samsung Syncmaster 275T and Dell Ultrasharp 2709 Why is the HP one (1920x1080) much cheaper than the other two? (the HP one is about $450, but other two are above $800) Why do people complain about Dell 2709 much more than Dell 2707? 3. What's the quality of the above three brands' displays? I have a HP 2207 and it hasn't got any problem since I bought it two years ago, but is this the general quality of HP displays? 4. If I buy at one of the above three displays at a non-official stores with 3-year warranty, do I get repair/exchanged if it has problems? 5. Is it a good time to get a 27" monitor? (meaning, price and technology) or are there any TV that are cheaper but has the same functions? Also: Are the three displays all TFT? Is TFT preferable technically? P.S : the three monitors: http://www.shopping.hp.com/product/display/display/1/storefronts/NT188AA%23ABA http://www.pcworld.com/reviews/product/30826/specs/syncmaster_275t.html http://accessories.us.dell.com/sna/products/Monitors/productdetail.aspx?c=us&l=en&s=bsd&cs=04&sku=223-9379 [Broken] Sorry for such long questions, and please use numbers to indicate which question you are answering.
