I have similar problem, both host and client running Win7 & TV12, I am offered "optimal resolution" of 1280x720 whereas it should be 1920x1080 which is what the remote laptop screen was running at (ie maximum resolution) before the teamviewer session. While connected with TV I am not able to change the resolution even within windows on the remote computer - only 1280x720p is offered there too. Anyone sitting at the remote computer can see 1920x1080 is still in operation but the sindows are all shuffled and resized to fit into a 1280x720 area. It used to work fine, so has something changed in a recent TV update?
