Is this monitor faulty?

post #1 of 6
Thread Starter 
I've just bought a Dell U2412H to replace my Hanns G 27.5" (HH281).
As I no longer need my Hanns G I wish to sell it but I'm worried it may have a fault.
It's hard to describe but basically there are diagonal lines going from the bottom left to top right, if you look hard they are there on the whole screen but they are quite visible at the bottom left hand corner if you have a white background. On a dark background they are invisible. This is not on the pixel layer, the pixel layer is faultless its almost like a backlight thing...but I've never not noticed this I don't think i.e. for as long as I've had the monitor its been like that but I've never really took much notice. So I assumed it was a design limitation..

I only bought on Jan 17th this year so I have just over a months retail warranty but obviously its a big thing to be sending back and forth only to be told its not faulty.

I've tried to take a picture:

How is the monitor connected, through a DVI cable? Try and swap it to another output on the graphics card and/or make sure the cable is snugly fitted both ends, perhaps give it a bit of a wiggle about and see if that has any effects on the lines. That will help show if it's a problem with the monitor or it's connection.

tried it all mate frown.gif DVI, VGA and HDMI. Two different computers, same dice. For the record my new monitor works like a peach.
I will give the retailer a call tomorrow and see what they say - the trouble is it's slight and barely noticable..something I would have to mention in my sale though and as a result I would sell for like..£100. If it was 100% guaranteed OK I would only sell for like £130..is £30 really worth my time and effort (bearing in mind the courier is £15 to ship it back)..could just make the buyer aware if it's not a serious issue

If it's the same as clock/phase on a CRT that's not it. The lines are static and not jittery..scroll down the page you linked and find the animated gifs about how it'll look when it's wrong

not like that at all. It's just a square patch of static diagonal lines in the bottom left hand corner that's only visible on a white background..

(poor paint skills)

to be honest it looks a bit like screen burn but there has been nothing left on my screen that looks like that or anything ever been left on my screen (monitor goes into standby after 10 minutes)
