Why does my second LCD monitor overflow, when I try to maximize windows?

My Display 2 is an old LCD monitor, Samsung SyncMaster 913V. This website lists its "Native Resolution" as 1280 x 1024. It fails to maximize programs perfectly. You can see below this problem with Notepad and Paint. I see that the 913V recommends 1024 x 768, but this makes everything look too big, so I picked 1920 x 1080.

https://superuser.com/a/1542311 didn't solve my problem, which doesn't happen on my Lenovo IdeaPad Y700 laptop, my Display 1. screen images

An LCD (unlike a typical CRT) has actual hardware pixels for the defined "native" resolution. If you set your video card (in this case, set your Windows display resolution) higher than the native resolution, the behavior is undefined. Possibilities include:

  • Blank display
  • Useless display (fuzzy, wavy, noise, etc.)
  • Truncated display (which sounds like what you are getting)
  • Squished display - e.g., if 1280 -> 1920 would result in every 3rd pixel disappearing.

But nothing you do can make an LCD display actually produce a true and proper image at a higher resolution.

In fact, Windows typically has a delay (something like "Do you want to keep this setting?") so that if you end up with a useless display then you just wait 15 seconds and the display reverts back to the previous setting.
