Compaq LTE Not Fullscreen

August 17, 2009 at 00:59:01
Specs: MS-DOS 6.22, Pentium 120Mhz 32Mb RAM
Hi,
I have two Compaq LTE laptop computers, an
LTE 5000 and an LTE 5250. Very similar, both
have around 32Mb of RAM or something. One
has a 75mhz Pentium and the other a 120Mhz
Pentium.
My problem is with the same OS and Software
my LTE 5000 runs MS-DOS in fullscreen while
when the LTE 5250 boots up, everything (and I
mean EVERYTHING) only takes up a small
portion of the screen.. leaving a black border
about an inch wide around the entire picture. It
is very useable this way, but i'd like the picture
to take up the entire monitor.
Thanks to anyone who can provide any help
here :\ I just cant figure this one out. The BIOS
reports the Internal Monitor's resolution at
800x600 default.

I think you need to install video drivers. Possibly other drivers too. Go to the link below by double clicking it and select your model. Also would be good to type in the number requested on that page.

Download all the drivers and the manual, if available, for your laptop. Might be good to get that stuff for the other laptop too. Save all the drivers to a secure place because they may not be available next time you look.

Install the video (graphics) driver for the 5250.

I just realized what OS you are using. I am not sure any drivers will be available or not.

Windows 3.1 even with the drivers from HP's support pages refuses to fill the entire screen. I have noticed however, windows 95 with the video drivers was able to switch to a resolution where the screen would fill. In the end though, MS-DOS still uses the little space in the middle leaving the black border around the edges.
The other LTE 5000-series I have runs MS-DOS just fine fullscreen.. this is why I'm confused.

When running DOS what resolution is being used and can you change the resolution at all?

Well to be honest I'm not sure what resolution its using by
default, but I'm 'assuming' its 800x600... or thats what the BIOS
say the Internal Display is set to. I do not know any way to
change this in BIOS nor in DOS? How do you even change
resolution in MS-DOS?

Been so long since I used MS-DOS I don't remember if you can either. You can't change it in the BIOS.

The BIOS is full screen isn't it?

No I cant change it in BIOS.
And nope the BIOS isnt fullscreen either :'(
The OTHER LTE 5000 series I have has fullscreen BIOS though ad they're the exact same BIOS version.

Are the displays on these two laptops the same size and ratio?

The LTE 5000 and 5250 have the exact same displays yes. It wasnt until later that Compaq gave the LTE series larger monitors.

My guess is that somewhere in the past someone has changed the display and used the wrong one.

That doesnt explain how windows 95 can utilize the entire screen
though. The resolution is just off in MS-DOS.

OK, I forgot that you said that. Something must be different with the BIOS.

Nope I updated them myself- they're exactly the same BIOS. I
got the update softpaq off the HP support site.

Is the BIOS on those laptops on chip or on the hard drive?

I ask because I didn't think those older motherboards had flashable BIOS chips.

I'm pretty sure its flashable.. Ive wiped the HD several times and
it didnt change the BIOS. To update them I just ran the softpaq
executable. I do know the BIOS are flashable on an old Packard
Bell 386 Legend I have as well.

I just had a thought. Are the graphics chips in both laptops the same exact chip? Are you using the same amount of dedicated RAM in each one?

Yep the two laptops have the same Cirrus Logic SVGA Chipset.

What about the amount of shared RAM each is using?

It looks like this has probably been addressed by the BIOS talks, but did you notice a setting for "panel fit" or "display stretching" or similar?

I don't know if such a setting existed on such old laptops, but it might, and if so...it'll do what you want.

Shared RAM may be a setting in the BIOS.

Its not I just checked :\... I have noticed though the BIOS says
the internal display resolution is 800x600 and MS-DOS appears
to be stuck in 640x480. Thats what is causing this problem I
believe.
