Yaar mujeh bhi LCD's k baray main itna nahin pata. But LCD wahan chala k check karo, uss ka viewing angle check karo, Contrast ratio check karo, model number dekh k internet say specifications check karo, aur phir price ka hisaab lagao.
Sasti teen chaar hazaar ki LCD lene say acha hay k banda CRT monitor le le. It has much better picture quality than those Sasti LCD's.
If you want Wide Screen OR if you intend to do some office work, these Sasti LCD's will do just fine. However they are not recommended for Gaming as the picture becomes too blurry even at the native resolution of the LCD. (Thats because of the low response time i guess)
In simple:
For Games = CRT [Keeping things in budget - produce sharper image]
For Office Work = LCD [3-4k, when you have less space to place the monitor]
And if you want to play games but still on LCD, i would say spend those extra bucks and get a new branded (Samsung/Dell - available locally) one.
