Most 4k TV have very good upscaller build in. Even 480p videos looks not bad.

I dont see any problems playing 1080p for normal eyes, unless your eye is like straight up imbalance to the point can see the image softness.

Of course there is no denying due to upscale there is a degree of softness apply, but to me it is very minimal (i only notice more of it at 480p videos)

In general Samsung seems to have one of the better up scale tech (i notice LG is more soft, but maybe that's just the IPS Panel)

Sony upscaller is not bad as well. I didnt try other brands like Hi Sense though.

Budget not mentioned

If you want cheap and good, for Samsung any of the 6 series will suffice

(MU6xxx, KU6xxx)

Technically I assume since you're primary media consumption is like 720p and 1080p, probably guessing streaming / downloads of Movies and TV series as well as maybe Astro?

You can also go shop to eyeball a few other equivalent models from other brands.

I would recommend Harvey Norman just to eyeball (but don't buy from them unless got good discount, evil customer here hahaha)

55" will sufficient enough for your content. Samsung series 6 and LG new model 2017 for budget 4k TV.

Warehouse Sales in ongoing today ... in Citta Mall, Harvey Norman... Can go there have a look...

Been using TV with mainly for 480p/720p/1080p with Samsung 55" KU6000...

Liking and and no such issue

My friend experience 2-3times broke in a year... Repair took a month+ each
But Sony dont have bluetooth and is just an internet tv.. worth it?

That would be a matter of personal preference. Some notice significant differences, others can't even tell when 1080p or 4k content is being played..

SA told me MU6100 this year was made from IPS panel, and we tested using finger some more and it seems true... last year model KU6100 is made of VA panel?

From where did the SA got the info that MU6100 is IPS panel? This is almost impossible because Samsung doesn't produce IPS panel and they will have to buy panel from LG, their largest competitor.
Yes, viewing angle is definitely better on IPS and IPS pixel level response time is faster, so less motion blur for sports and fast moving scenes. Also the non black color reproduction is better as well, check out those LG SUHD TV with 10bits panel, the color is just impressive. The biggest problem for IPS is contrast, if you will watch the TV in dark room like bedroom at night, don't buy IPS TV, the black is bad with light bleed. But for large well lit living room, the IPS TV can produce quite good picture even watching from side.

I find IPS color reproduction abit less spot on than VA Panel though. Might be my eye problem hahaha.

But yes Contrast is the biggest difference I can see.

I find IPS Panel best suited for smaller screen (like 23 inch monitor, or handheld screen) while VA is more suited for beyond 55 inch. (but that's just my bias, and maybe i'm just spoiled by KS7000 VA panel)

Of course, OLED is another breed altogether XD.

Just bought an UA65MU6100, waiting the shop sending to my house tomorrow. Price RM4999, donno is good deal or not.

Quite excited eventough it is a basic 4k tv(Currently using toshiba 40inch five years already, for sizewise, really a big different). First time buying basic 4k samsung tv, hopefully it can serve me at least few years time lahhh..

At first considering Panasonic EX600K 65inch,best price RM5575. But it dont have bluetooth function, expensive than MU6100, for picture quality i cant really see major difference, so at last i bought MU6100.

Will share more once received the TV tomorrow. Thanks
