Answer is no... I will not buy a display set. Cos the panel has limited lifespan... and the tv is on for at least 6-8 hours a day. If the display set is there for like 3 months, you can count how many hours the tv is on non-stop. Not very good lar... heat is an enemy of electronics, so prefer not to buy display set. Rather settle for a lower end model.
In reality, a lot of features you won't use lar... so go for the largest screen possible with the minimum extras. Guarantee you won't use smart tv function cos it's painfully slow. So ignore the operating system, not worth your time. Don't need 4K also cos got no material now... plus your HD free to air is going to look even more crap stretched out. Also don't need 3D unless you're a particular fan of it. Different movies do 3D differently, some are good most are bad. Basically, just need a good panel, wide viewing angles, good colour, good black depth, and preferably as non-reflective a surface as possible.
The money you save, get a good tv mount on the wall that allows you to pull the tv out to plug in cables or plug out, tilt the tv forwards or backwards to avoid reflections from ceiling lights.
Then after you buy, don't look anymore... just enjoy your tv...
Note: Bigger is better... try for 65 to 70 inches... really shiok! I have the Sony 70W850B... 70 inches of full HD shiokness...
