Well, first of all, Jack, for a monitor to be 3D compatible it has to be 120Hz, so if there is and I will look, it will have to be 120Hz.
Here you go, ASUS is the only maker that I could find for one. And that is perfectly fine as they are probably the best monitor manufacturer out there. This one has the emitter for the 3D glasses on the top and also has lightboost and the glasses with it for $550. The other ones do not have the emitter and do not have the glasses, and only one had lightboost, meaning that you would have to purchase the kit for the glasses and emitter, which are not cheap. (Traditional 3D glasses make the screen look very dark, so lightboost simply lightens it by doing a few different things. It also makes it much easier to play and almost eliminates the headaches and sore eyes that you would experience otherwise).
