any recommendation of the above?specific model?budget RM400. thanks. My AOC 19" monitor spoil because of my main power button shut down

Plenty of choices around your budget range. I suggest dropping by a shop where you can audit them personally and then see which you prefer.

Acer K222HQL - RM354
AOC E2250SWD - RM359
LG 22M45D - RM379
Samsung S22C170BS - RM349
Viewsonic VA2246 - RM349

thanks rav3n82.oh ya forgot to add somemore. I need DVI-D input. what if i want to convert DVI-D to HDMI using adapter?

Sorry, you mean your main display output from your PC is DVI-D, so you need a monitor that has DVI-D port? Try to check out the specs of the monitor I suggested above. Most (if not all) have DVI-D port. And yes, a DVI-D to HDMI adapter would also work if your monitor lacks any DVI-D port.

yes indeed. u get what i mean. i need those with DVI-D input. so your best recommendation would be?

Aesthetics-wise, they all look nearly the same. LOL. I have not personally tested monitors around this range yet, so I recommend you try seeing them for yourself which has the best color reproduction.
