I have a 20" core 2 duo iMac setup in my kitchen. However, the screen is sooo shiny and glossy, it's hard to read in the morning due to the sunlight reflecting off the screen. So I did a Google search and found this:
It's a custom sized anti-glare film for the iMac! They have a 20" and 24" version, anti-glare and clear. They both work as a screen protector as well, which is perfect since the whole family likes to touch the screen as they point, or the kids forget to cover their mouth when they sneeze.
Today, I installed the film on the screen per the directions. It was tough keeping the lint and dust off, but I just angled the screen down to minimize falling lint/dust from landing. I used the included wiping cloth with a bit of windex squirted on a corner to clean the screen off. Pulled the plastic film off the anti-glare film an inch at the top, applied it, and then pull the plastic film half way. Otherwise, the silicon adhesive wouldn't stick. I don't think the adhesive is either sufficient or "sticky" enough. More on that issue later.
My impression of the anti-glare film is that it isn't perfect. I was hoping to have a film that cuts a lot of the reflection without reducing visibility, but alas, there's still bright spots on the screen, just not as bright or focused. It also cut the brightness by 10-15% which isn't that big a deal since the max brightness is way too bright to begin with. There's also the "sparkles" typical of diffusers, which makes the whole screen look like it has water streaks. This is the most annoying part of the film. The other problem I have with it is that the edges don't cling to the screen. There's edge "bubbling" so to speak where it's not completely affixed to the screen. I can live with it, since it's in the black bezel area, but it tells me the silicon adhesive isn't sufficient. I have other silicon adhesive backed films on my phones and such, but I haven't had this issue with those.
Overall, I'll keep it just to protect the screen, but hopefully a better anti-glare film will be available sooner rather than later by Photodon or someone else. At least it'll help with the fingerprint clean up and potential scratches from pens and other things the kids use to point on the screen.
