[QUOTE=Metalcastr;34396314]Can you post a pic?[/QUOTE] Post a pic of what? The gradient banding? [editline]26th January 2012[/editline] How am i supposed to do that? I thought screenshots gets taken from the computer and not the monitor.
Try another monitor?
[QUOTE=Warship;34400608]Try another monitor?[/QUOTE] Does that mean i will have to buy a new one?
Don't you have an old monitor lying around?
[QUOTE=Warship;34401693]Don't you have an old monitor lying around?[/QUOTE] I do, but it's a very small monitor using a 1024x768 resolution.
Just use it to see if it also has the gradient problem
I heard there are some monitors that just don't support proper dithering. Not so much that it's a problem with the monitor, as it is that it just doesn't have the feature. Mine doesn't support it either. (Which sucks because this was quite the expensive monitor...) What is Dithering?: [url]http://searchcio-midmarket.techtarget.com/definition/dithering[/url] [quote]Dithering also occurs when a display monitor attempts to display images specified with more colors than the monitor is equipped to handle.[/quote] This is what you're most likely experiencing. [editline]27th January 2012[/editline] In other words, you can't really "fix" it. You can only really buy a new one and make sure it supports more colors to lessen or eliminate the problem, or has a way to counteract it with a feature.
How severe is it, anyway?

I get horizontal lines or vertical lines. Looks something like this: [img]http://www.prad.de/images/monitore/lg_ips231p/banding.jpg[/img]
It's not small dots, it looks pretty much like that actually. To make sure though, are you using VGA, DVI or HDMI?
[QUOTE=SuperDuperScoot;34416033]It's not small dots, it looks pretty much like that actually. To make sure though, are you using VGA, DVI or HDMI?[/QUOTE] DVI. I wrote that in the OP.
I completely missed that, I'm very sorry. Uhm... I don't have much else I could tell you then, other then the dithering thing.
[QUOTE=SuperDuperScoot;34416106]I completely missed that, I'm very sorry. Uhm... I don't have much else I could tell you then, other then the dithering thing.[/QUOTE] Well that sucks. I hope i can return it to the store and hopefully buy a new one.
How can i be sure that a monitor supports proper dithering?
I just checked my monitor and it has some slight banding but not that severe. Try calibrate your monitor brightness / gamma / contrast and see if that helps reduce it.

I have now returned the monitor to the shop there i bought it, and they said that they will return it to Benq, and they will determine if the screen is broken or not. Now i have to use my small ass 1024x768 monitor for a few days :suicide: Also, my old monitor don't have this gradient banding problem (atleast not that much). It's from 2003, i think. It's an old LG Flatron :v:
