Hi Wim,
I'm writing to you because it sounds like you know what you're doing, whereas I don't.
I have two Acer Inspire 10.5" netbooks (one XP and one Windows 7) and one Dell (Vista) laptop. I just bought the Toshiba 14" USB monitor and installed the driver from your website on all 3 computers. Using the Dell, the display on the Toshiba monitor is fine, fills the screen, and there are no issues with it. However, both Acers display only on a very small area of the Toshiba monitor. In other words, the display on the Toshiba is almost as small as the one on the tiny netbooks themselves, making use of the 14" USB monitor essentially pointless. Of course, I bought the montior specifically to use with the Acers.
I've fiddled with all the settings I can think of but nothing enlarges the Toshiba display using the Acers. The Toshiba website says nothing about this problem and from what I hear, their telephone support is very bad. Can you help? The Dell uses no Dell startup screen but the Acers do. Might that software be interfering and, if so, how could I disable it? Or do I need to bite the bullet, call Acer, and have them tell me to call Toshiba? They, of course, will tell me to call you. Does it sound like a driver problem that might someday be addressed in an update?
Many thanks in advance.
