actually, maybe so.

'vga mode' actually applies to crt, cathode ray tube, displays. laptops came
along long after crt and because of being 'solid state' [ss] design, laptop
screens and solid state monitors have their own dot pattern array, as apposed
to phosphor dot pattern, and sweep rates. which gives them their own vga
*emulation* modes.

i can not comment on ibm's early multi window red led flat screen monitor
because i never saw any tech spec for them. they were large and impressive.

which is different between *crt* and *ss* displays.
