Isn't display scaling set individually for each display? You could disable that for your 24" display (unless it's a 4K Display, at which point you'd want scaling)

Scaling is wonky on Windows. I use my SP3 in a dock, connected to a 1080P display, and use the SP3 as a secondary display. If I scale the SP up at all (which would be nice at 125% due to distance), and leave the second screen at 100%, the large screen looks all soft (but not scaled). If I leave both at 100%, the larger display looks normally sharp.
This isn't a big deal to me, to keep the SP3 at 100%, because it is relatively low resolution. The difference in 125% and 100% isn't huge. 150% is the recommended scaling, but that is too much IMO. The Surface Book has a much higher resolution screen. It isn't usable, to me, at desktop range (or any range really), at 100%. Its recommended scale is 200%, which is also too large for me. I leave the SB at 150%, but this does lead to a soft external display when the external display is scaled at 100%. Things are just too tiny on the SB at 100%, so if I had to live with the larger screen looking soft, I would. For now, I just keep the SP3.
