HP 27 Display on Windows 11

[Algernon70]

Please add a category for "Display".

I bought a new Dell that came with Windows 11. My old Dell was running Windows 10. My HP 27 Curved Display worked great on the old machine but the aspect ratio on the new machine is really off. If I open a Word document or a PDF or a browser page on the new machine, what should appear as a portrait rectangle appears as a square. It does print correctly so I know the data is fine. I have reinstalled the display driver but nothing seems to help. Any thoughts? Thanks.

@Algernon70 -- in the top-right corner of any window created on your screen by Windows are three icons:

1. the "X" (to close the window) as the furthest to the right
2. the "underscore" (to hide the window) as the left-most 
3. a "square" between the other 2 icons

Click that "square" to tell Windows to expand the window to cover 100% of your computer's screen.

Thanks for the reply but I probably didn't explain the problem correctly. The issue is not the size of a given window, it is the fact that the way Windows 11 is rendering the window and its contents is not correct. Either there is an issue with the graphics card in the new Dell or there a Windows option that I haven't found yet that I need to change. Or HP needs to change the driver for Windows 11. For example, let's say I have a .jpg of a square. On Windows 10, it IS a square. I can measure it with a ruler and prove it. On my iMac, it IS a square. On the new Dell with Windows 11, it is a rectangle (stretched in the horizontal direction). And this is happening for everything, not just graphics. A large, bold font is noticeably "fatter" on Windows 11. Everything is stretched. So what I am asking is has anyone else observed this problem. My first take is: it's a Windows 11 issue. But my second take is: it's an HP Display Driver for Windows 11 issue.

@Algernon70 -- Windows 11 should be using the "Plug-and-Play" features of the monitor, to obtain the physical dimensions of the screen, and the resolution (in pixels) of the monitor, to set the computer's graphic adapter to those "recommended settings" --- 

Then, when drawing a "square", it will compensate for the resolution of the monitor and the physical dimensions of the monitor's screen.

So, on your computer, are you using the "recommended" settings?

Have you used the OSD (On Screen Display) on the monitor, to force the monitor to some different resolution?

You are a Wizard! That was the exact problem. And I even now think I know why Windows 11 was not using the "recommended" settings. I suspect it is because when I first powered the new machine up out of the box, I had an old ViewSonic display plugged into it so I could keep running my old machine with the HP display until I transferred all the files over. Windows must have set the specification based on that and never "saw" that I changed displays.

BTW, I never could "get to" "Control Panel > All Control Panel Items" referred to in your post. I had to manually type it in. And there was no "Display" in it. But thanks to your direction, I was able to go through "Setting > Display" and change to the "recommended" settings.  

Thanks again! It's nice to have things look the way they should.
