Maximized windows don't fit screen.

Screenshot here.

Just installed Windows 10 on a new SSD, and all maximized window borders don't reach where they're supposed to.

As you can see, the top border makes contact but the left, right, and bottom borders do not. Every window I've tried has done this except for, for some reason, Steam. Even the standard Explorer windows do this.

Any help is much appreciated.

Another annoying issue: In Windows 7 and 8, you could click and drag the top of a maximized window, and it would automatically shrink and allow you to move it around. In Windows 10, the only way I can move a maximized window is if I restore down it first, then move it and re-maximize it. It was because I had Aero Snap disabled. The fact that they gave this a special title gave me the idea it would be more annoying than normal, so I disabled it. Either way, at least this part is fixed.

What graphics card are you using? Could be a driver issue causing the Windows to have the borders.

My computer is fine.

Have you also tried a different resolution on your screen?

I'm using two GTX 780s in SLI, my resolution is 5760x1080, and my drivers are the most recent drivers for Windows 10.

Needless to say, it's not a graphics card or driver problem.

Hello, I have registered because I am having the same issue. Have you managed to fix it?

I suppose it's nice to know a fresh OS install might not fix it, since that's where I was headed next. I'm using an R9 390 running at 2560x1080 resolution, but it happens in 1920x1080 as well.

Thanks

Do you have tablet mode enabled by mistake?

I have tablet mode turned off. But I'll note that it still occurs while in tablet mode. Actually, the problem is even worse in tablet mode, because I am unable to close a program. Here are some images in both tablet and non-tablet mode.

I did a bit more investigating and discovered that it seems to happen mostly after the monitor wakes from automatic shut off.

I also noticed that we're both running ultra-wide resolutions. Do you think that could be part of the issue?

For those who have older video cards (mine is an AMD 4350 from 2009 on a HP Pavilion Desktop), and have a 2 inch black border with no content inside your monitor window, here is a registry hack that works.

HERE: How to Fix: Windows 10 Black Border (Shrinking Screen) | www.infopackets.com

Every time Windows-10 does a major update, my max window size decreases to leave that 2 inch black border on all 4 corners. This Registry change is a pain in the but for those of us who don't like following detailed instructions, but it works.

Thankfully we'll only have to do it until we decide to upgrade to a modern P.C..
