My new Dell 2007WFP is showing screenburn! A first on TFT's!?!?!

I'm genuinely suprised to see that I'm the first to spot this, secondly to see this on a fairly expensive IPS Panel!!

I never thought LCD screens suffered this, nevermind an S-IPS panel! :eek:

The images speak for themselves.

Excuse the quality as I'm still learning about ISO levels and so on.

Here's my desktop:

This panel was near perfect, it had no noticable blacklight bleed, no dead pixels. I'm already getting my second panel replaced on Monday, not sure what to do on this. It's clearly unacceptable :(
 
it's not a first i'm afraid, it can happen on LCD's, but is rarely long lasting. It's quite rare for it to happen on new screens, and is normally something old models suffer from after a few years. Panel technology doesn't really make any difference. All you can do really is get it swapped out, it shouldn't do it that easily. To be safe, it's always a good idea to set monitor to auto turn off after 10 mins (or whatever) or use a screensaver
 
One of my old Sonys developed this fault, I too didn't know it could happen on a tft, strangely my other sony that is even older doesn't have the problem, don't really care now I have my 2407 :D
 
I seem to recall that this is more properly called 'persistence' in the case of a TFT not 'screen burn'.

Net results look similar but have a different cause.

It can often be reversed just by leaving the TFT off for an extended period of time or suing a white screen saver can also help.
 
I have had this problem on all my IPS panels. I think its a common problem. I had 4 NEC LCD2080UXi's that suffered as well as my LCD2090UXi and also my Dell 2007WFP has it. You just have to be carefull when leaving your screen viewing objects for a long period of time.
 
Screensavers are a bit pointless because it means you're still using energy (both by the monitor being on, and the PC no-doubt using CPU/GPU to render the screensaver). It's probably better to have the display(s) switch off after 15 minutes or so of inactivity.
 
I have just got one of these screens i would be very interested to find out the sort of time the screen has been exposed to the graphics to create this sort of persistence.

I understand that having the screen turn off is more energy efficient but there is a problem with bringing a screen out of standby quickly as it normally takes about upwards of 4-5 seconds and about 10 seconds before the screen is back upto full brightness.

What I am planning to do is set a simple windows xp screen saver to come on after say 1 or 2 mins and then have the screen turn off after 5 mins of inactivity which should be a good compromise.

I am also now surfing with a full screen firefox window as there are some icons on the right of my desktop that could potentially cause some persistence.

Is screenburn where it looks all grainy?

It's where an image that has been left on the screen for a long period of time has been "burned" on to the screen, so for example if you leave IE open with a webpage loaded, once you close it you will still be able to see some parts of the webpage slightly.
 
It takes only a few minutes or so for the image to stick, but it only takes 30 or so seconds for the screen to return back to normal. I have never had an issue with icons but its still possible for them to cause problems. The main issue i have is the title bar, the top left corner of the monitors seems to be the worst place for it.

What i do is create 3 new images with paint, set the image size to your screen resolution and create 1 blue, green and red background images filling it with the colour. Save the images separately and use the 'My picutres Slideshow' screen saver to display each of the images and rotate every 6 seconds or so. I have never had a problem with permanent damage doing things this way.

Do be carefull as 1 of my 2080's was completely ruined becuase i left a dark coloured page running for about a hour and 20 minutes. The top area (where the title bar is) was so No swearing! it looked like it had water leaking into it and it never returned to its natural state.

Cutting the power to the LCD matrix for a few minutes will reset any burn effects in most cases.

It's pretty rare to see on such a new panel though. I've still not seen any on my Hitachi CML174's and I've had these for years and they are turned on a lot.

i'd edit that swear word. also give dell a ring, get that screen swapped if it has happened so quickly.
 
I've had this before. The fix seems to be setting a bright white background and leaving it on that all night, or using one of those graphic intensive GL screensavers.
 
I've seen persistence issues many times on my Dell 2405, but in every case they have cleared up in a day or two of using a different program or just leaving it off while I've been away over a weekend.

Been a total non-issue for me really.
 
Never had this problem on my 2007WFP yet, and I've certainly used the web for over 3 hours in a single session, with the taskbar there the whole time and the screensaver not getting to kick in (because I was using the PC). So I don't accept that the image burns within a few minutes, or it doesn't on mine anyway.

FWIW my settings are screensaver on 5 mins, screen off after 10 mins, and if I'm ever leaving the PC on while not using it (downloading or whatever) I always switch the screen off.

does this help? it claims that it will fix image persistence, but has anyone tried it? something im concerned about as i will shortly be making the jump from crt...

My 5-6yr old Samsung 181T is really vulnerable to "persistence".......it is a getting on a bit now tho!

JScreenFix will remove the persistence but it doesn't "fix" it. A couple of hours browsing with Firefox and the title bar is back :rolleyes:
