Only the 55 inches of older models of X7000E are VA , 55 inches of X7000F is IPS .
That's pretty much the difference , you are paying extra for the Android OS. But Sony 's TV Android OS is prone to crashes and sluggishness , some people prefer it because it offers more apps . They have also removed some of the trivial features such as the support of 5GHz Wifi on the XF70 .
Because it is the better TV among your options for dimmer rooms ,  any difference you see in the shop might as well be the result of different settings .
The Samsung TVs  will look more washed out when viewed from the sides because it has narrow viewing angles ( which is the flaw of VA Panel based TV) . But it is a little better for watching HDR content thanks to the coverage of wider color space.
That's the thing with 4K TVs ,  if you don't sit close enough to the screen , any picture improvement to 4k is not very visible to our eyes ,  hence not worth paying extra for the 4K upgrades .
It's difficult to say if TV A or TV B has better upscaling , because any difference might be caused by different sharpness settings.
Most big brands TV runs a very identical upscaling algorithm , but certain brands like Samsung's TV tend to overscan the screen causing the overall picture to look a bit more blurry .
Once these extra processing effects are turned off , the upscaling quality should look pretty much the same unless you are running test patterns and using magnifier to spot the difference.

The primary difference between the two is still the HDR performance . The 6800x supports a wider color space than LE580X but this colors improvement is only visible in HDR TV shows , movies and games .  If you don't watch / play HDR content , might as well stick with the 580x.

thanks, i am scaling down my 1st 4k tv, it would be either a sony of a samsung, hope to get your 2 cents on this

1) Sony kd49x7500f
2) Samsung ua49mu6100kxxm

what i know so far
1) sony known for better durability, but the UI is poor, and the android OS sometimes causes the tv to hang or lag
2) Samsung, not as durable as sony, but has excellent colors, and has something like a mouse pointer to ease browsing

hope to get your opinion coz not really apple to apple comparison... thanks

Anyway, set arriving tomorrow and we shall see.

Quoted LG 55Uk65 @ Rm2800 + Rm250 Cash voucher. Worth it ?

Hi, looking to buy a 4k tv mainly to play ps4 pro and watch some videos (non-4k) with budget RM3k. Currently looking at:

Sony
KD55x7000e ~RM2.6k
KD49x8000e ~RM3k

Samsung
UA55MU6100 ~RM2.7k
UA50NU7400 ~RM3k

LG
55UJ630t ~RM2.4k
49SJ800t ~RM3k

Which one should I go for? Also is it worth going for wcg ie 49SJ800t/KD49x8000e/UA50NU7400 but with smaller screen size? Is it worth to get smaller screen size + wcg for the PQ difference?

LG 49SJ800T

LG 50UK6300PTE

SAMSUNG 49NU7100

which one better? No problem with the budget.

guys, what is the different between LG UK6300 & UK6320?..
beside the magic remote included or no maybe?
