i received my lc60ua6800x today... been playing with it for hours!

it's rather easy for me to set up everything and test all that i want to since i have used the predecessor lc50ue630x for 2.5 years now.

the tv is used together with himedia q10pro android box, denon avr, unifi tv stb and unifi 100mbps wifi.

below some of my initial findings and comments:-

.. 60" is significantly larger than 50"! well, that's how i felt on the first day.
my eyes are still getting used to it sitting at 10-12ft sway.
.. the remote is a 2-in-1 (with voice search) compared to the previous model which has 2 remotes.
i find the buttons too close to each other.... problem with mis-pressing with my fat fingers.
.. the UI is good, better than the last one, quicker in accessing controls, settings, etc.
.. the native usb player has improved in that it can now read ntfs, 2TB hdd; but... it can only do aac and dolby audio.
can't do dts or other higher - u just get video, no audio. this is not a problem for me as i dun use the tv for hdd playback.
.. use of airmouse or wireless mouse is fine, no problem.
.. sideloaded apps on androidtv (android 7.0) work fine - astrogo and a couple more for news, int'l live tv channels... for casual viewing.
(i do not want to put too many as i prefer to use my android box for others like kodi and acestream.)
.. youtube works good, plays 1080p, 4k with ease. (not using netflix... no comments.)
.. tv audio is surprisingly not bad... maybe due to this "eilex prism" feature.
.. optical arc is fine, all tv audio whether from tv usb player, androidtv apps or other player will work with arc - dolby digital works if applicable.
.. the wifi module is good, works on 5ghz just like its predecessor.

.. using my box for local playback, HDR works fine. if the file u play is HDR, "HDR" will be displayed when u press the display button on the remote.
.. i tried a variety of files and no surprise the 2160p hdr10 files come out the best followed by full 1080p ones.
.. HDR10 videos surely have deeper and brighter colors.
.. this tv is definitely brighter than its predecessor - even the default settings on the modes - std, movie, dynamic, etc. are quite bright.
unless u activate OPC which will get too dim.
.. i like standard mode most but may use an adjusted dynamic mode for some HDR videos.

overall, i m satisfied with it - it does what i expected it to do.

from desa home theater.. for rm3.5k, 5 year warranty, free delivery+installation, 1-for-1 exchange within 7 days if faulty.. i can't and won't ask for more!

Sharp std warranty is 2 years.

Only during promotion periods u get +3 for free.

Visit the stores, see if promo still on.

This tv.... many promotions, offers in last 6 months.

The built-in TV player app itself can't decode files with DTS and DD+ and higher.

Try and let us know. I know VLC could play most files, if not all, on this TV with audio decoded and output to the TV's speakers. So I think Plex might just works fine.
Sony has DD+ support and of course DTS.
And this too. 

it Wil b very hard to ask to install app, connect to home theater to test in a shop.

With your box, can u not play ext storage files direct with kodi for dd, dts, etc.? If no, it means yr box is not supporting kodi fully, need plex.

Kodi works on the tv android too but androidtv now does not allow reading of ext hdd, restricted to internal memory only. That is why I did not mention kodi but only vlc, mx.

Is this Plex app on Android (AndroidTV?) that has bug?

My Plex app for LG webOs seems fine though. No problem with all those audio.

not going nas anytime but a little curious...

what android box are u using?

UJ630T.

DTS, DTS-HD (probably downstream to DTS only), AC3, E-AC3 (DD+) all can play. Built-in player a bit picky. Doesn't work well with mp4 file coded with complex audio codec, but MKV's are ok. Sometimes it said Audio not supported, but still has sound. 

You can try ESH @ Starling. The staff members there were accommodating when I wanted to test some Dolby video files. They even install VLC upon my request.

Plex can download online subtitle automatically. Displaying it usually is not a problem for Plex. That's why I was tempted to get an Intel NUC to host my PMS, but costly.

does it happen to all apps u tried to download?

is any app working good? youtube?

this happens when the internet connection speed is too low.
old q5 or newer q5pro?

old q5 won't do.

if q5pro, i remember reading a case where the nas app player did not work well but the q5pro media center's native player handled nas well.

Sorry.. then i dun understand below...

But never mind, as long as u get waht u want.

Anyone tried side loading Ookla's speed test app into the TV?
