Qosmio F750: Ghosting may mean defective display?
Posted: 27-Mar-2012 20:50

Hi!

I've got a short question: I'm a little bit unsure if the ghosting effect I spot on my F750 (glasses-free model) may be the result of a defective display. If I run the x-tune utility in the "professional mode", I see a clear green image when closing one eye and if I close the other eye, I indeed see a red area (as supposed) but there are still huge "greenish" areas visible. Almost the entire right quarter of the display is flickering green. If I adjust the effect as told by the application, the effect will only get even worse.

According to the face tracking window, my eyes are detected correctly and I'm also using sufficient lightning and viewing distance.

So, what's the experience other users get? Do you see clearly green and red areas? How about ghosting in movies or games?

Hi

I think ghosting effect is nothing unusual in the wide LCD panel world.
I’ve got an LCD 42” TV and a light ghosting effect is visible.. most in the bottom display area…
I read a lot about such effect and this is nothing unusual. Sometimes it’s more visible on black background.

Not sure about your issue… maybe you should get in contact with an Toshiba ASP in your country in order to check this…

But ghosting effects are common for LCDs no matter what manufacture or product..

Yes, of course I'm award of this issues. But in contrast to classical separation methods like shutter glasses, I thought that the glasses free technology consits of a huge amount of micro lenses just in front of the display which are "directed" to either one or the other eye.

Having this in mind, I guessed that maybe the control of these lenses might be defective. Please don't get me wrong: If this behaviour is as expected by the design of this technology, I won't have any problems with it. I was just wondering if anyone else is experiencing the same effect. I don't want to contact my local ASP if it's not a hardware defect because I barely need the laptop almost every day
