I noticed the same while I viewed it in the store when just turned on or in some of the menu page, thought it was part of the colour background. I can't test as I have not had my TV delivered yet.

Please do share your finding

i am not sure but i think i know what u mean.

i think it is part of the tv launcher at startup.



btw, may be good if u will edit the secondary title of this thread to sharp ue630x series since that was the outcome for you, may be useful for others!

Ok I've checked using your test video. On green, red it is not so noticeable, but on grey scene it is uneven and can see led light bleed.

I also noticed it on my HTC One M8 hand phone though. Does it mean it is defective or it is the character of the led backlight?

I have no idea as I'm not very knowledgable about TVs. Maybe @bond can chip in as he was the one who posted the test video link

Uneven light distribution is usually associated with the quality of the panel, i doubt it is classify as defect, anyway, you may report to sharp service and share the outcome.

I think such is the norm for most LED TVs.. Getting a warranty claim for such is dicey and your TV might be returned with an even worse panel, so best to stick with the current panel if it's not too disturbing. For handphones, I doubt that but I guess it depends on the screen type.. Samsung flagship phones with Super AMOLED screens aren't plagued by such issues. 4K OLED displays are the future as they do not require to be backlit. Hoping the R&D guys iron out the current bugs & achieve cheaper manufacturing costs..

ok, signed up for netflix free trial over the weekend ....

try watching daredevil 4k and it played even tho i'm only on unifi 5mbps.
but PQ i don't think it is 4k but still very very good...

now addicted to it.... better cancel while the addiction is not too great....

thks for all the info..

there is display for every tv show - hd, uhd. no display = sd 480p.

yr ue630x tv has good upscaling, so the 480p comes out good too.

i would think with 5mbps, u are getting just sd even if u subsribe uhd.



now, u should try IFLIX!

it's free for 1 yr at least.

however, iflix app does not appear on the tv's playstore.

so, need to get es file explorer first (it is in playstore)

next, find a way to get the iflix APK from somewhere else.

then, install apk via usb on the tv using es file explorer.

I noticed there are 2 settings on HDMI1 :-

1) Limited
2) Full 4:4:4

Option 2 has warning that only if your hardware support.

Which one do you use?

Also does the Sharp UE630X have any sports function or motion function that can be turned on/off?

hdmi1 - full.
this is for my android box 4k capable and a new 4k hdmi cable.
works ok, no problem.

all other hdmi's - set to limited.

i confirm that with tv optical audio output bitstream setting, can get dd 5.1 on netflix, beside uhd 4k video.



as we now start to discuss more on SHARP UE630X series, i again suggest u amend thread secondary title so that users and potential buyers know this thread has some good info for this brand series. i don't notice another thread for SHARP UHD 4K TV!

Agree cause me now are leaning towards SHARP after several people here owns it...

it's a good 4k tv.

i posted my comments about netflix and iflix on this tv - both work very well.

check the threads if interested.

Did you try by displaying black picture on screen and turn the lights off? Sounds to me like typical black uniformity issues of LCD, especially edge lit ones in bigger sizes.

After reading I found that it is inherent problem with all Led Tvs. As long as it is not apparent on normal viewing it's ok.

Yup, limitation of the technology itself. Things will improve as we go along, like OLED. The link does give some calibration tips to lower the impact.

Any idea if it is edge lit or back lit?

been playing with the audio functions of sharp ue630x, a summary:

.. all 4 hdmi's used as inputs, hdmi1 not used as arc.
.. optical output set to bitstream.
.. optical output connected to avr as input.


.. netflix - can get dd5.1, good (with hd/4k video).
.. direct usb tv playback give good results - for both dts and dd.
.. same files playback with standalone android/media player audio pass thru- only dd is produced on avr, good; dts downgraded to lpcm, poor.

it is strange why direct tv usb playback can produce dts at optical but not when using hdmi input from another player.


anyone has an explanation?

Back-lit.
