Does DESQview support Super VGA or video coprocessors?
A302: Yes and no. When DVC is placing windows on the screen, it cannot use any of the 132 column modes provided by Super VGA cards. The smallest text font that DVC and DV386 provides to VGA+ users is 60 rows by 80 columns. Since video support is hardcoded into DVC and DV386, there is no way to write a video driver for Super VGA cards. Inside a window, any resolution can be used. The problem occurs when you switch away from the window and come back. DESQview will corrupt the window unless it has a resolution of 800x600x16 or less. Except in rare cases, DESQview cannot handle 256 colors at more than 320×200. A few cards will reportedly work at 1024x768x16 as well. Note that at these higher resolutions, “Graphics Pages” in Change A Program must be set to 4.
