As others have noted text might be scaled when Windows is told to enlarge text (i.e. 125%, 150%, etc) but applications software which does not rely upon Windows's scaling of characters that you need to set are problematic.
Keep in mind that any depiction of text. based upon character's fixed maxtrix size (e.g. 10x7) does not necessarily understand and accommodate a change in overall monitor pixel count. So if a 10x7 character looks great on a 13" monitor, if I put more total display area in the pixel count, my character size is reduced. 10/1024 vs. 10/2048 is 0.97% vs 0.58% when the monitor remains 15". A character would look identical in size if I compared 10 pixel character on a 15" 1024x768 monitor vs. a 30" 2048x1536 monitor.
- I went from desktop 19" 1280x1024 monitor to 27" 2650x1440 monitor, all the characters are smaller in size on the new monitor, if both are used with Windows 7 text at 100%. That is because a doubling of pixel count accompanied by only 40% increase in monitor size makes a single character only 70% of its size on the old monitor. If I increase the Windows scaling to 125%, reading POTN on my browser looks fine with Chrome, but some other applications just don't display properly.
- Simlarly, I purchased a 15" laptop and increased from 1280x1024 pixels to 1600x1400 15" laptop. Again, a 20% shrinking of a single character size. I had previously used a laptop with 15" 1400x1200 pixel count, which was quite livable, but the 1600x1400 is almost not manageable...perhaps because my eyes are 15 years older too.
So increasing the pixel count needs to have a somewhat
proportional change in the overall monitor size as well, for readable text.
So, for the OP consideration of two 13" laptops, the text on the 1800V vs on the 1024V pixel monitor will be 45% smaller on the 1800V displayed webpage, or the 1800v laptop needs to have 45% larger size, or 18.8"
