accaptable backlight bleeding on Asus VH236H?

[amd7674]

Friend of my yesterday bought Asus VH236H. The monitor looks great, colors, brightness and contrast. However IMHO there is exceessive backlight bleeding around the edges (left, right, top and bottom) of the screen when viewing the black backgrounds in the dark room. After going thru 200+ reviews on newegg, I couldn't find anyone complaining about it and some people even said there is "no backlight bleeding" at all on their units. Did she buy a lemmon? I'll try to take a picture of it tonight so you guys can see it yourself. She already returned one of the previous LCD montiors (as it was too small) and I don't think the owner of a small local computer store will go for another swap, unless there is a legit problem with it.

Is the exccessive backlight bleeding covered by the warranty? and how much backlight bleeding is considered excessive? or should she contact Asus about it?

i have the vk246h. It's just fine.

If it is is excessive, I'd defiantly contact support though Asus. The worst that can happen is they say no.

Asus LCD warranty page does not cover backlight issue, perhaps it is a normal LCD limitation. I guess I'll have to call them about it. Since it is pretty common problem with cheap LCDs, chances are replacment might exhibit same problems or even be worst....

I have an Asus VK246H which has an acceptable level of backlight bleeding. What's considered "acceptable" varies from person to person.

For example, if my NEC 2690WUXi or Planar PX2611w exhibited the same amount of backlight bleeding as my Asus I would have returned them. The Asus is used sporatically, in fact, I didn't even turn it on this month.

If you want to get feedback regarding your own situation, then post a picture of it.

I know what you mean my current Nec 20WMGX2 has none backlight bleeding (perfect uniform backlight), I guess at the end you get what you pay for... Recently I was playing with Acer H213H (21.5" TN panel) and as far as remember and I hate to say it, it had much less bleeding then my friends Asus LCD. What is weird, Asus shows some white bleeding from sides too, I would expect top/bottom portion to be only affected. Other than bleeding, the montior looks great... I wonder if adding some light into the room would lesser the bleeding effect...

I have a 30" LCD, bleeds on the corners to varying degrees (top left is the worst, bottom right is more or less flawless), manufacturer even included a demonstration picture in the manual showing what they considered "acceptable" (the corners being the maximum acceptable) and what was considered a "defect" (a huge blob in the center of the screen or an entire side), it sorta just comes with the display tech (I've seen monitors more expensive than this one bleed worse....)

I'd say its only excessive if it interferes with using the display, so while my monitor may have bleed, its un-noticed except for when the monitor is powering on (it displays a manufacturer logo on boot) or has no input and isn't in sleep mode, I really don't care what the screen looks like in those conditions, it looks uniform in Windows, games, and when used as a TV

if your Asus has bleeding that makes it a pain to use (i.e: its non-uniform), yes, I would consider that excessive, if this shop owner doesn't want to service you, feel free to call the BBB and local chamber of commerce, make some noise, let the guy realize he's a small business and has to compete with the whales like Amazon (who will more or less swap products until you're happy as long as you're willing to pay some of the shipping price)

yes thats somewhat harsh, but its unacceptable customer service if the response is "you already got served once, everybody gets one"

Sorry for the PQ, I hope you will see what I mean. Beside top/botton bleeding, there is bleeding coming from the sides I've used game mode (lighter pictures) and theater (darker pictures). Also what worries me there is a tiny buzzing sound coming from the back of the panel when I'm using theater mode.....

Should my friend try to swap it for another VH236H?.... Does this bleeding looks normal to you guys?

Pictures tend to magnify the problem, but even taking that into account it still looks like too much backlight bleed to me ( i can't be 100% sure though)

Some advice for dealing with the local shop owner: remain polite but firm the entire time. See if he's willing to either refund or exchange, since this would be a second return then personally i'd go for the refund since you wouldn't want to test him a third time. It's a little dishonest but you can leave the monitor in theater mode so when he fires it up and tests it, he can hear the buzzing noise. Remind him that monitors recently have been plagued with "bad capacitors" and you wouldn't want a monitor that exhibits strange "noises" right out of the box.

He'll probably end up returning it to his own supplier.

Good luck either way.

Without any distance information it's impossible to know whether these pictures are mostly showing backlight bleed or off-axis glow. Given that it's a TN panel, the top and bottom are most likely glow, not bleed. I don't know about the left and right.

Take a picture from at least 3 meters away, or as far back as you can go, and then it should only show backlight bleed (if there is any).

I think the long exposure pictures exaggerate the problem. If you buy another and compare it to that one I would bet it would be the same.

 

[obobski]

if that looks the same in pictures as it does in real life, I'd make them give you a new one, thats about 90000x worse than my 30", and worse than any large format I've seen recently

sjetski has good advice dealing with the shop owner, although I'd say once you're done with this exchange/return, you're done with this shop as well

Thank you for your feedback. I'm posting few more pictures from a little further away. I figure it out the buzzing noise. It is not related to the 'display' mode, but to the brightness level, anything below 89 will produce a light buzzing sound on the back of the panel. So it could a 'bad capacitor' or something else after all . IMHO this Asus panel's backlight is not uniform ('game mode' shows it the most). So I guess after reading your comments my friend should swap it for another VH236 or should she ask for another brand? I wonder if the 'brightness level' buzzing is normal or the unit she has is faulty. Also I don't get the bleeding from the sides, I'm not an expert but I thought the bleeding problem is always from the top/bottom...

Please tell me if I'm not being picky and I should just get use to it. Perhaps the buzzing nose is normal too ??!??!

Thank you all for your help and HAPPY NEW YEAR TO EVERYONE !!!!!!!!!!!!
