Thread: Small screen size under DOS and Window 95 on laptop

    Unhappy Small screen size under DOS and Window 95 on laptop

    Hi guys,
    Recently I came in possession of the Compaq Armada 7750MT laptop. It is very powerful beast with 1024x768 screen.
    But since I have installed Windows 95 there I came across two problems.

    1) All games (well Doom in particular, I have not tested others yet) under DOS are on small screen. I suppose they are being displayed at 640x480 resolution. However DOS itself runs full screen. Is there a way to make them run in full screen on LCD screen?

    2) Second, but related to this first problem is under Windows 95. It too runs not in full screen. The problem is with drivers. There is S3 Aurora64V+ graphic card there. I can't find drivers anywhere so I cant set resolution to screen native values.

    In any other computer/laptop when I set low resolution on Windows it obviously looks like crap, but fills whole screen. Why here it is different?
    I have run all BIOS setting but did not found any related setting.

    I think if you solve problem #2, you'll solve problem #1.

    Found a Windows NT driver at https://www.driverguide.com/driver/d...4d630fd940e387 and with a little more searching you should be able to find one.

    An alternative is to run Windows 98 SE which is better than W95 in every way and comes with more drivers.

    Well I have already found driver for S3 Aurora64V+ for Windows 95 so screen size is no longer a problem under Windows 95 native applications.
    However it is still a problem under DOS where Windows drivers do not apply.

    I am considering upgrading to Windows 98 but I wanted to bring this laptop to its original state. Besides I have no computer running Win95 yet few with Win98.

    Then you need to find the manual for your laptop, as there might be a key combination or a BIOS setting that enables stretching to fullscreeen.

    Compaqs were well known for not supporting hardware scaling of video, instead putting the video centered at 1:1 resolution, creating black borders. I don't know when Compaq started it but it is likely later than this machine. Get yourself an IBM with a TFT display if you want hardware scalin, or get a 640x480 laptop. I can help you pick one out. Most laptops didn't come with scaling anyway until around 1998/PIII era.
    Wanted: Any old clunky 286-P1 machine that has some kind of working battery or replaceable with off the shelf parts. Preferred: 10+lbs 386 machines.
