Got 2 different monitors, both have same problem!

karkee · Mar 27, 2016

So for our office I got 2 new monitors.

An LG ultrawide 34uc87c and a dell U2717D , both have this sort of vignetting effect around the screen ...

Is this normal because of the small borders ? My old qnix did not have this sort of problem.

Same problem has also been stated here:

https://hardforum.com/threads/dell-u2717d.1893166/

I have the same sort of effect around the borders and its so annoying.

Does anyone know if for example the U2715H also have this sort of problem or anyone else with the LG ultrawides?

That is backlight bleed and is normal for the monitor, just that it can be worse for some units.

Yeah, it's to be expected with IPS displays. Every single IPS monitor will suffer from it to some extent.

Your BLB is very acceptable for an IPS panel.

So the edges causing shadow is because of the backlight bleed? If you have a word doc open it even makes the start of text unreadable.

I never had anything of this sort before, is it because of the thin borders?

BLB shouldn't affect normal usage. If you haven't try lowering your brightness some.

Here's some examples,

Hopefully it wouldn't look as bad with the brightness turned down some.

Personally BLB drives me crazy and I avoid IPS since IPS glow makes bleed stick out worse.

*Noticed your linked pictures. For an IPS, that's acceptable.

Yeah but its not only that, the sides of the monitor cause this blurry/viginating effect. It is not really backlight bleed its almost a shadow on the borders probably because of the gap between panel and screen.

For example if you would open a txt the first letter written is blurry because of this unless you view it from dead on. Almost like its going behind what the monitor is capable of showing.

The same goes for a browser on the right side the scroll bar is blurry unless you view it straight on.

And this is really annoying...

thin bezel will cause IPS glow for sure.

I think I see what you mean but your post is confusing since the first pic has nothing to do with it. Anyways the effect you're seeing should only be visible from very wide angles, and yes the thinner bezel is the cause of this, since that means the backlight won't cover the whole screen at very wide angles. Shouldn't be an issue during normal use.

However that BLB on the Dell looks very bad.

He's not talking about backlight bleed. He's talking about a few pixels at the edge of the screen fading when you look at it from an angle. It's a peculiarity with LG.Display's AH-IPS panels, which is what most modern IPS monitors use right now. It's not something unique to that monitor or to Dell.

Thanks for the information. I wonder if all of them have it, and if I can return it as faulty for this.

Here's a question for you, OP.
What about providing pictures of the problem on your own monitors? That way we know exactly what you are talking about and how bad it is.
Not trying to be rude, just trying to help out.

It's a normal property, all AH-IPS monitors will have it. That includes all LG monitors and most Dell monitors.

More like all thin-bezelled monitors. The backlight isn't large enough to cover the edges from a wide angle. My XB271HU does this too.

Got 2 different monitors, both have same problem!
