Reddit reviews Polarizing Filter (6 in. x 6 in.)

From what I read it looks like this is kind of what you want:https://youtu.be/MHFPOKyDUcg
This guy did it with clear plastic of some kind.
Personally I think you need some kind of plastic with a anti sun layer like your sunglasses. I think it is this https://www.amazon.com/gp/aw/d/B009P8B548/ref=pd_aw_sim_sbs_328_2?ie=UTF8&psc=1&refRID=V98YPDXAE5GKAP13FEVF
put it on a a clear pice of plastic for strength. Please note that the direction of the polarizing filter. I think if you want to go full diy you can use the polarizing filter from a old screen https://youtu.be/zL_HAmWQTgA

*Please note I am not a expect. This is just some quick thinking and making use of my small experience with hololence*****

I hope this helps

This is what I found online, which one do you use specifically? This looks promising

i did it myself. get one of these and note the reviewers are mostly idiots that didn't realize it ships with protective plastic film on each side that needs to be removed:

remove your cluster, peel off the existing polarizing filter from the screen, and clean the screen with alcohol

plug the cluster back in to your bike while still disassembled and turn electrics on

hold the new filter above the screen and rotate until you get the desired color, then mark the filter where the corners of the screen are

use a razor to cut a piece of the filter you bought, using the marks you made and the old filter's shape as a guide. remove the protective film from the new filter then tape it onto the screen at the edges (which are hidden by a bezel) and reassemble

same exact method works for any lcd screen
