Any chance you have a version that we can set the size?
CRT's are pretty much not sold any more. Here are the common sizes for LCD's. Since you have to make it fixed and want to make sure it accommodates the most people. While 1024 is livable, 1280 would be preferred and fit monitors 15.4 and above..
Here is an idea. Two versions.. One 1024 for standard aspect ratio monitors and laptops and 1280 for wide screens.
