No fixes exist outside using a monitor on the VGA output (if present at all), you either live with the small box in the middle of screen or ugly badly scaled full screen image.

This is not always true.

A user here provided a TSR that fixed this very problem on my 720CDT:

Toshiba Tecra 720CDT = Great DOS Gaming Laptop

Another user later reported that it worked in his 430cdt:
toshiba 430 cdt screen scaling?

It's worth a try!

It categorizes as a small box in middle of screen (just less small), not filling the whole screen. One is not gonna get anything along the lines of what newer laptops do where any resolution is relatively smoothly scaled to fill the screen.

well duh, it IS an old laptop. 🙄

also the margin is minimal from what I recall, like 16-24 pixels of border.

I wonder if something like this exists for the Pentium III Gateway Solo I have. The screen on that sucker is 1280x1024 and it does no scaling at all on anything below 🙁. DOSBox obviously fixes the issue but games like DOOM are too much for it to emulate smoothly. I have a Celeron Thinkpad that does scale and has nice OPL3 emulation but the screen is an ugly off shade of yellow.

This is just how it was with laptops, and the reason why Laptops with OPL3 sound and 640x480 TFT screens are so highly praised for DOS gaming.
