Samsung Outdoor TV with Anti-Glare Coatings and 2000 nits brightnessIf you folks want to solve the glare issue, it is done in two ways: Anti-Glare coatings and boosting display brightness (backlight). It ain't cheap, but would certainly solve the problem.
If you go through a McD's drive-thru, all of them have similar displays but those are commercial-use oriented, made to go 24/7/365 for 5+ years.
There are other manufacturers of Outdoor displays such as PeerlessAV, Sunbrite, etc.
