I have a relatively simple problem which I just cannot resolve. I have two monitors, one beside the other (in desktop extension, so that I have a wide desktop and can slide stuff seamlessly from one to the other). The first is 1920 x 1200, the other is 1920 x 1080. However, they are physically different sizes. The first is approx. 21.625" wide, so the horizontal resolution is about 88/89 dpi. The second is approx. 20", and thus 96 dpi. If I have a page open in Word, the 210mm appears on the second monitor as 210mm. If I slide it over onto the other monitor, naturally it becomes larger, about 230mm. Which is what one would expect. However, I would prefer that it was the other way round. The document to be correctly sized on the first monitor and thus become a bit smaller if I move it to the second. I remember being here before and telling Word or the OS that I was using an 88dpi, which means also that 1:1 really means 1:1 in Photoshop and other important software. However, my ancient (77) memory is shot to pieces and I cannot find it. Since I did it before some years ago with W7, I can only think it is Mr Gates' bunch done something in W10.
