W510 800x600 resolution Panel Fitting

I did a forum search to see that I the answer to my question hadn't be solved already. But since I only found my own thread with the open question, I decided to throw in my post here. Even though this could theoretically be called a necropost and I should have made a brand new duplicate. Forum ethics is sometimes so confusing. Anyhow. My mother recently got an ASUS tablet/PC hybrid so I finally got my chance at testing where the error lies. I installed same program on both machines, and then tested it out. 1. Both my ACER and her ASUS machines added black panels when requesting full screen. 2. CTRL + ALT + F11 however changed this on the ASUS (One of the transformers I believe) by first removing all black areas over and under, second press made the sides removed as well, and I had my full screen 800x600 legacy game. But doing the same on the ACER (Iconia W510), the CTRL + ALT + F11 key does nothing. 3. There seemed to be some bug on ASUS that made the 800x600 resolution stay afterwards and it displayed the windows desktop in a centered 800x600 window with black bars around. This could be solved by setting up the resolution again. So now that I had confirmed Windows 8 is not the issue, all that remains is blaming graphics cards or drivers. An interesting part is that the ASUS could display fullscreen 800x600, but it did not have a resolution option for 800x600 in the resolution list. (Maybe it supports it but finds it to be so old nobody would choose it and hides it) Some further info on how I'm doing it, since Padgett asked in the past. I set my old program to "full screen" and run it from either desktop or from the "start screen" where you can add links. In all cases it goes to the desktop and then goes into the fake fullscreen mode where it just fills the sides with black, instead of "stretching" or "changing resolution". I could of course (and I do) run it as windowed and have my desktop background behind. It is mostly about how I'd like it to work, and how I've now found competition to work. Anyway, it would be interesting to know if my problem is buying an ACER product and I should avoid them in the future, or if I simply got the wrong hardware specs for what I wish to do with the Tablet. (Perhaps it is just the screen / graphics card that has these limitations and another ACER would have fulfilled my expectations) I don't know if any ACER employees check by these forums, but it would have been interesting to hear how it is. Might have to call them up sometime, but this doesn't seem like the most obvious topic for someone to answer over phone. I was looking for their e-mail support, but sadly couldn't find it.
