Gerard,
I've been looking for a solution to this for a while with no luck. I tried some tinted plastic covers from Office Depot (
here are some pictures ). It help tremendously with glare, but also block out much of the brightness and crispness of the display. Some have recommended going to a photo store and getting some polarizing film, which I have not yet tried.
Let us know if you come up with a solution, because many people have complained about this.
