I will test a few more blu rays on my PS3 and PS4...
I also have a ps4, seems to make a lousy blueray player. Disk drive is very noisy, and the hdmi handshake makes it look like im running pixel flipper from wow when initializing a connection.

There's also this thread:

And yes me too. One of the reasons I keep my contrast setting at 50 or below (currently 44).

I did a few more tests for the bezel "issue". I used "Dredd", "Sin City", "300", and "Batman Begins" blu rays. I played each blu ray on my PS4 and PS3. Unlike the previous test, my room was dark except for bias lighting behind the ZT. The bezel was NOT distinguishable from the top and the bottom bars at normal viewing distance when the TV was displaying movie content. I could only see the bezel when the screen was completely dark, or I was close to 1 feet from the screen.

I'm glad you put issue in quotes. wink.gif You had a bias light on, however, which changes the viewing dynamics. He can correct me if I'm wrong, but I'm pretty sure "music_to_my_ears" is wanting to know if the bezel disappears in blackout conditions, to which I again say not all the time.

Yeah, PS4 is not a great blue ray player right now. It lacks 3D blue ray support. It has issues with up-converting interlaced signal. There is also an issue with surround sound for Netflix and some games. I am sticking with PS3 as my primary blu ray/Netflix player for now. It sucks because I love PS4 interface. Hopefully, Sony will address these issues with new firmware.

I thought about testing in blackout conditions also, but I got lazy lol. BTW, after getting bias lighting, I would not watch the tv any other way. It is just much more comfortable viewing for my eyes.

I wouldn't doubt it whatsoever. Might switch to that soon...it makes OLED even less desirable. wink.gif I thought of grabbing the Antec Bias Lighting from Amazon since the asking price is such a bargain. Only caveat is less than an idea color temperature for cinematic purposes, but my panel has yet to be calibrated anyway...
post #5199 of 11428
This is what I got and I really like it. Its supposed to be the recommended 6500k.

Did you notice it get worse before it gets better? The three lines I saw last night turned into 5 tonight eek.gif

Thanks, the only offputting part is the length. Did you find it substantial enough for a 65" TV?

I have Antec bias lighting.

http://www.amazon.com/Antec-HDTV-51-1-Inch-BIAS-LIGHTING/dp/B007TG5EG8/ref=sr_1_1?s=electronics&ie=UTF8&qid=1387419158&sr=1-1&keywords=bias+lighting

Antec website states that the bias light is calibrated to 6500K, but I have not tested the claim myself. It is rated up to 60 inches, but I did not have any issues on my 65 inch ZT. It is USB powered, so it turns on/off when I turn on/off the ZT. It also has independent on/off switch, so I can still turn it off when the TV is on. It uses sticky abrasive to stick to the back of a TV.

There is one issue though. The sticky abrasive is not strong enough to hold the light in place at one side due to USB cable weight. After a few hours, a few inches at one side gets detached. I resolved to using a sticky tape, but even the tape is not strong enough to hold it in place for more than a day. I have been trying to find a solution, but short of using glue, I am not sure how to solve this. I do not want to use glue because I do not want to have the light permanently attached to the TV. Perhaps, there is milder glue that I can find.

That's the affordable one I had in mind. It seems to not truly be at 6500k, but that USB power connectivity might be what pushes me over the edge in favor of grabbing it (that and the price). Cable ties might be a solution to keep it in place...

Suits me ok. Are you wall mounted? That Antec looks like its ok too. Its longer and cheaper. Mine has a switch rather than USB. Which I like actually because sometimes I like the light to be on when the tv is off.

If its as light as mine you can use scotch tape.
post #5206 of 11428
Not wall-mounted, and I won't care to have it on while the TV is off, though that might make for some nice ambiance. It sounds like tape isn't holding it for SwiftSweeper...only way I'll know for myself is to give it a go!
post #5207 of 11428
Is this backlighting a personal preference thing? I thought we were going for a "dark room" for optimum performance. Do most people use this?

Thanks

To clarify, Antec has the switch also. I normally turn the bias light off with the switch when I watch the TV during a day. If the switch on position, the light will turn on/off with the TV.

Cool.
Not competing or anything seriously. But it just occurered to me that you can get a dimmer switch for mine. I didnt get one because they want way too much for it. Like $20 I think.
Seems like either one would do a decent job.
post #5210 of 11428
Upon close inspection re: vertical banding, I do see very very dim bands almost across the entire display when looking at medium/light gray fields which appears to also be causing the slight DSE I have. Is this just due to the nature of plasma tech in general or abnormal?

Some claim that proper bias lighting improves perception of contrast because eyes are not as dilated as in a dark room. It also reduces eye strain because one can easily distinguish a TV from the wall that is behind the TV.

In my case, I no longer feel blinded when the TV goes from a dark scene to a very bright scene. I also find convenient to have additional light in the room.

My feelings exactly. I havent noticed better colors or blacker blacks like some people claim. But it definitely reduces eye strain and fatigue. And as you noted I just like having a little ambient light in the room.
post #5214 of 11428
Be careful with those dimmer switches if plugged directly into the wall, they cause ground loop hum, my experience is anything more then off and less then 100%.

Also i think, that my banding might have gotten worse after the first 50-100 hours. Really hoping it gets better. My other zt has a stuck pixel, and very very slight banding, that you cannot really see at all, that doesnt concern me in the slightest.

I was watching some history channel today, and about 1 1/2 hours into it i changed content, noticed some IR. Took about 3-4 to fade. Did the same thing with the other zt, same results. I notice IR is most noticable on a red screen.

Neo plasma panasonic seam to do like this when break in and after it suppose come better from my experience.

About the antec light i just check and want buy it coz just 2 left in stock so on amazon.com i recive an error said this cant be delivering at my adress, lol was 20 dollard, so i move to amazon.ca and they have it but at 25 dollard and when i put on my card they ask me 17.49 dollard for ship me this, lol and lol so i decide to delete this item, hehehe crazy quebec.

You might want to check out Ideal Lume.

Their bias lights are more expensive at $59.99 US, but they are actually calibrated to 6500K. I believe that they ship to Canada too.

I use ideal Lume bias lighting and they do ship to Canada. I have been very happy with the lights. Be sure to order an extra bulb or two. Cheaper to get the extra ones up front than ordering them separately down the road.

Is it ok to run the built in screen wipe overnight? I had seen some people say you shouldn't run it for an extended period of time.

Is this more effective than the pixel flipper for late arriving banding?
