Question Chromatic aberration or panel misalignment?

Long time lurker. First time poster.


I have a Epson HC2100 with a few hundred hours on it. There is a green tint on one side and red tint on the other side. It is still under warranty and I would like to know whether it get would worse with use or stay the same.


Photo attached with test pattern.


Any ideas?

That's not chromatic aberration.

I would contact Epson as your under warranty.

Known issue on LCD projectors in general, but much more common on older models. I believe it has to do with color filter degradation. Contact Epson and demand a replacement.

It is visible only in some scenes. Should this replaced as I have no idea whether it is a serious issue or not.

It’s not very serious, and usually will not grow. It’s mostly visible in scenes with lots of white or gray. But if you have warranty, then why not replace it?

This is very common in LCD projectors. I am not sure if Epson will replace it or not but it is possible your replacement might even be worse. It shouldn't be very obvious in normal viewing.

I called Epson and they said that they will send me an refurbished one. I hope the refurbished is not worse than the current one.

It's not uncommon with LCD projectors. It's difficult to tell from your photograph how bad it is. Most of the time, it's only visible with a test pattern as you have done. Epson will allow a certain amount within specification.

Check the replacement right away and if it's worse or no improvement as for another replacement.
