consider the Viewsonic VX2450wm-LED for RM649,it's big [23.6"],it's thin,it's rather cheap [relatively]

or the LG E2350T for RM549,it's thin,it's a 23" LCD,it's corners are rounded,it's image quality is good for a TN

Have you tried gaming on a LCD before?If you have then what's the exact model?The reason i'm asking is because older TN panel LCDs are as 'slow' as today's cheap IPS and VA variants found on TVs.Non-TN panel LCDs/TVs have better colours and viewing angles so it'll be more enjoyable if you watch movies/videos on it.
Anyway here's some LCDs that i personally recommend
LG W2343T-PF 23" RM469 [Quite accurate colours,good contrast ratio,cheap]
Dell U2311H 23" RM599 [eIPS panel so accurate and nicely saturated colours,large vertical viewing angles,fast for an IPS,good contrast ratio]

Most TN 23" are around RM5XX and they aren't good in terms of colours and viewing angles except for one model i've seen before namely the LG W2343T-PF  at RM469,it's colours are relatively accurate and the contrast ratio is good.Viewing angles aren't bad but it's still TN so don't put your hopes too high.

Didn't notice any ghosting with it.I doubt most people can too 
You can also ask other forumers about it,there's quite a number of U2311H users here.
