Plasma & LCD TV Image Retention

This post is about Image Retention. We talk about how to try and avoid image retention, and fix it if it is too late. Here are some quick removal ideas to help you with all this phenomenon that affects Plasma & LCD TVs.

Image Retention (Screen Burn) Summary

This is probably the most important section to read. Failing to prevent Image Retention will render your plasma or LCD TV as useless, it will not be covered by the warranty and it can occur within a few hours of getting it home. Not only that but some of the most likely causes are NOT what most people are on the lookout for. Image Retention CAN be prevented almost completely.

What Is Image Retention

Image Retention is where an image you were viewing on the Plasma or LCD screen remains there either temporarily or eventually permanently even after we have finished displaying it. The result in minor cases is that an annoying ghost image appears when we are watching our favourite program and in the worst case the retention is so bad that the display is totally unwatchable.

If you want to try something now to remove Image Retention then check out 3 popular methods for removing LCD or Plasma Image Retention.

PixelProtector


There is a commercial DVD for just such problems. It is called PixelProtector (Pixel Protector) and retails for about £25.


JScreenFIx for Image Retention Removal

Another thing you can try include downloading a free program called JScreenFix. It creates fast random patterns on your PC. The only snag is the headache of connecting the pc up and the fact that removal technique will not be running at your screens native resolution (for the TV). But this is well worth a try if you have the time to spare.

Use The PC For Image Retention In Fix

If you can hook your PC up to your Image Retention TV try this. Create a folder in 'My Documents' called 'Image Retention'. Now open up a picture editor like 'paint' available on all Windows PC's. When you run 'Paint' a blank white document is what you should have in front of you. That is exactly what you need. Select File – Save as and name your picture 'white'. Be sure to save it in the folder you just created.

Next you need to click on the 'black' section of the colour pallete at the bottom of the 'Paint' window. After you have selected black click on the 'Fill' icon (a tipped paint pot) on the left. Now simply click in the middle of your white picture and it should become totally black. Select File – Save as and name you picture 'black'. Again be sure to save it in the folder called 'Image Retention'. You don't need paint any more so you can shut it down.

Now right click on the Windows desktop an select Properties – Screen Saver and using the drop down list select 'My Pictures Slide Show'. Now to configure the slide show. Click Settings and configure as follows. Slide the bar to 'More' so that pictures change frequently. Slide the next bar to 'Larger' so pictures fill the whole screen. Now click the 'browse' button and find the folder you made called 'Image Retention'. In the next set of options:- Check 'Stretch Small Pictures', Uncheck 'Show File Names', Check 'Use Screen Transitions' and finally uncheck 'Allow Scrolling Through Pictures With The Keyboard'. Save the options.

Different versions of Windows might have slightly different configuration options but as long as the result is a completely filled (no borders), alternating white and black screen with no writing then it will probably help.

Now let your screensaver run. Leave this for a at least a few hours to see some results. If you use your TV for the PC then it might be a good idea to use this as your regular screen saver and run it frequently.

Conclusion

The first method (PixelProtector) is fast, safe and efective but it obviously is not free. The second method is free, can be awkward if your PC is not connected to the TV in question and I would not run it too frequently as the long term effect on a screen is not certain. The third method (my method) is free and safe but slower than the first two but of course suffers from the 'pain in the neck' problem of connecting the PC to the TV.

I suppose it depends on your individual situation what is the best solution for you.

I hope this post has been of some help. Laviva Online Store
