I've been re-doing alot of the code that rd uses to set the screen resolution and I beleive that it's now possible to implement some odd-ball screen settings similar to how arcade os could do. I've tested it and I can force the refresh rate and bit depth to anything I want, even if win won't let you select it via the control panel.....
Once beta5 is released I would apprecitate it if anyone who has an arcade monitor and a jpac would help me test this out, sicne I have no way of doing this.
