buy the size according to your viewing distance and space.
if too short distance, 60" is not a better choice than 50".
also, what u watch - if mostly HD/4k stuff, 60" might be better if distance is good enough.

Hi bro. Can help my out.

My viewing distance is about 1.8m - 2.2m. Maybe will just play HD 720p or FHD stuff. Never own FHD/4K tv before.

I look around with the viewing distance calculator. They said 49" is enough. Will 55" or 60" become too big for my distance?

Thanks in advance.

6-7ft... i wud suggest u go for 40" only.

that size, 4k does not mean much, 1080p is fine.

50" is best for 8-10ft; 60" 11-12 ft.

if u view too large at a short distance, yr eyes get tired very easily, u won't like it.

above is just my judgment and experience.

my sofas are within 4 - 12 feets, and mostly watch astro or 1080 movie. shall i get 50" or 60"?

Anyone can advice calibration for this tv model. I find the colour very dull compared to my old LG tv.

Can’t seem to find the calibration settings on RTINGS

hi, i just got my lc60ua6800x few days, sometimes after the tv off long time when i power on back it's black screen without anything few seconds and off it back, then i try to on it again , it appears android afterback back to normal.
whats wrong with this

Video will be transmitted via SB -> TV. Change TV to HDMI input which is connected to the SB. You'll see some display from the SB, like menu and such. That's where the video from BR would be broadcast-ed, while sound stays with the SB.

this is the std and correct way to connect a box player via AVR or soundbar, then to tv.

the thing is some people want to do hdmi arc for the sake of not switching on the avr/soundbar if they just want audio from tv.
soundbar is using just one input (from box) and one output to tv.

player passes video+audio to soundbar; soundbar process/output audio while passthru video signals only to tv.
try that connection, forget the hdmi arc for while, see if u get audio lag or not... u shudn't.

i have tried to connect tv box audio out to soundbar via optical cable, no issue with the lips sync.

the soundbar i got has only 1 hdmi port. so the above matters is not available for me 

bolded part.

i think u totally cut off power when switch off, correct?

if u do that, the next time u power up, the android needs to restart... u wait a bit for that.

try switching off with remote but do NOT cut off power.

then u see diff.

never cut off power , coz my socket very difficult to reach

I have Sharp LC60UA6500X and Sony KDL40W660E. Sony performs better in terms of clarity, color and brightness although its not 4k.

It's just me or the netflix app keeps showing black screen sometimes when preview is showing? I just got the tv today lol, so slow delivery. Also it came with android 8 out of box.

just checked.

netlfix is fine.

I guess it's because of weak wifi signal that causing it, can't load too fast.

what speed u hv, how far from router?
