First TP LCD with a video scaler?

#1 Post by Thinkpad4by3 » Fri Jun 07, 2019 12:01 pm

What was the first TP/TP model with a certain LCD that supported automatically upscaling the image instead of centering it with black bars?
Thinkpad4by3's Law of the Universe.

The efficiency of two screens equally sized with equal numbers if pixels are equal. The time spent by a 4:3 user complaining about 16:9 is proportional to the inefficiency working with a 16:9 display, therefore the amount of useful work extracted is equal.

The 760XD had it. Dunno about the older ones.

I know for sure the 800x600 365's and the 760-series had scaling but I don't know if the 755CX-HBx (I believe it's the first Thinkpad with a 800x600 screen) had any scaling since it used the WD902C24A graphics card which was used only in 640x480 machines. All BIOSes should show some kind of option for screen expansion but if not, the DOS config utility ps2.exe can turn it on with the command "ps2.exe HVEXP On". Don't expect good quality scaling with any pre-2000 era Thinkpad - I think the T2x/X2x/A2x series were the first to have proper scaling.
