Do you use the desktop for Microsoft Office / typing words etc?

well if u r going to use that just for computer usage, I would say better go for normal monitor

because TV got many other components eg tv antenna port, USB port, HDMI port, AV sound ports, speakers which you are not using . more components means more headache especially when it is spoilt

If you prefer tv for your desktop, you need a higher pixel density tv so the text will not be blurry.

Depending on where you put your desktop, if you are surfing from a couch, then get a tv.

Personally I prefer monitor so I dont need to strain the eyes when reading texts.
What size of monitor are you looking into?

Definitely. 

What's the screen size would you prefer?

so far I don't see the benefits of curve monitors. they r just marketing gimmicks and look "cool" but they r expensive

Curved monitor have disadvantages, the viewing angles, you need to be directly in front of the monitor or else the picture will not look right.

Here's some monitors around your budget with 27 inch screen.

Acer R271
Acer K272HL

Not that different from when I am using 27inch monitor just that I sit slightly further.

My living room setup:

if i'm you , i will choose a 32 inch full hd tv over a 2x inch monitor full hd

easily can get any branded 32 inch full hd tv below rm800

if your budget can be increase , get a 24 inch above 4k monitor even better xD~

Perhaps maybe helpful for TS.

Welcome, have you finally bought your 27 inch monitor?

That is good, hope you will get the Dell monitor soon.
