So much of the problem is just how little action there actually is. Even when I watch the Rams, I've got Red Zone going on another screen. Most of the initiatives I've seen are basically cool stuff that could easily be sent to home viewers, but are being walled off to in-stadium viewers.
Stuff like multiple replay angles on your tablet or phone, the replay cam on the jumbotron, or interactive apps that only work on the stadium network. Supposedly the 49ers stadium is going to be this techno wiz-bang structure that's going to make all the other owners demand an upgrade for their buildings
edit: Not sure how it's a monitor if it has a tuner. I used to have a 32" Samsung that worked great as a monitor when used in DVI-PC mode. But iirc, all models below that size used inferior panels. My advice is to buy from Amazon/Costco so you can get a no hassle return if it doesn't work for you
edit 2: Candlestick is such an awful stadium. It's always been bizarre seeing that corner of section of seats empty
