Sometimes people don't tell us everything, because they don't think it's important.
I have viewsonic pro8200 and xbox 360 ... going from 360 straight into back of pro8200 via hdmi cable that came with the pro8200.
Now, I do see not exactly a boarder but, when auto keystone kicks in, I get a good excellent picture and around the outside, like a boarder, but , that's normal.
Now if it is solid black 1 inch boarder, I don't think I get that, just extra space around picture, and it doesn't bother me either, like you. Now, you could do factory reset on the pro8200 and see if that fixes it. It's hard to know what you are describing, could you take photo or video of it. But if it doesn't bother you, and Coderguy said he did run into that problem and sort of forgot how he fixed it and offered his best shot at it, sounds like maybe some setting somewhere fixes it. Trial and Error. And post what you did to fix it, so it helps others.
I know when I first got my pro8200 , I didn't know what to expect. I was disappointed at first, but then as I relaxed and used it a couple of days, and read the forum room and got ideas on setup, I liked it a lot. There are 33 pages of people posting, mostly when they first got it, and didn't know how to set it up right, with xbox, blu ray player, a/v receiver, etc. So lots of tips. Maybe someone else in the thread had that problem,and posted something.
Coderguy and BSE53 have very good troubling shooting skills, and Coderguy did try to help you, maybe BSE53 will show up and give his 2 cents, too.
