I'll steal my own post from a similar thread (as this one will probably stay open):
It's a Proview Monitor. Proview merged with Mag Innovision, hence "MagView." I think that Proview changed the cases on the old monitors that used to be sold, then unloaded them on Best Buy (note the warranty is only 1 year, vs. the usual 3 year one. It also refers to Best Buy right on the warranty card!)
I think if you go to
http://www.proview.net and download the driver, it *may* fix the problem (you can get it by clicking on "Downloads" at the top, then downloading the magviewpnp.exe file).
I bought the 17" version (VM-700E) and this monitor still won't go up to 1280x1024 as the sticker right on the front says it would. I thought the driver from their site would fix it, but it didn't. They'll probably try to blame it on your video card if you call them.
