Ok I was trying to remove my anti glare using the rag method but ended up taking up the polarizer as well. So no that I have to replace the polarizer I am wondering if taking the 2nd one off and replacing both polarizers with some super-high contrast would be worth it. My idea is to buy a sheet use a large piece for the polarizer that would go on the lamp side of the lcd and then place a smaller piece close to the triplet. From what I have read that will work but two questions that I still have after spending some time over the last week are first, how is keystone correction affected if i place the polarizer by the triplet as opposed to right after the lcd? And second How difficult is it to replace both polarizers? It seems that a few have done it but I can't find any detailed instructions or in depth accounts of the degree of difficulty of it.

Most of your answers are here - it's just a matter of locating them. It's best to search the LL Forums using Google, as you can specify more parameters.

Here are a few threads you might find useful.

And by adding +keystone -3D (as you're not concerned with 3D projection and a bunch of hits come up dealing with that): site:lumenlab.com +replace +polarizers +keystone -3D

Keystone correction should not be affected as it's all just light to the fresnels. Correction: Just saw this:
QUOTE
Keystoning will work fine if the polarizer is placed back on the panel, or in it's own frame. It will also work fine on the keystone mechanism, just not perfect. This, of course, is because the analyzer will become both less tranmissive and less efficient as the angle of incidence increases. If you use standard panel orientation, then this is not an issue at all.
