Yeah but that's still not far enough, the idea of large screen like that was to have a minimal distance away from the TV, and its not 26".
Make sure you go with a smoked glass and do not use the dynamic mode on your TV your eyes are going to get tired of the huge screen really quickly.
As Edge said there are other threads discussing this, if you had a pedestal where you are 4-5 ft away from the screen that makes more sense. I know going big on the screen is tempting but theres reasons why not to do it in an upright.
Unless your going to play alot of fighting games, the screen will be wasted as the correct aspect of most mame games wont cover even a 1/3 of that screen unstretched.
Also,
Any reason why you rounded over your edges, i take it your not going to use t-moulding?
