I've been helping my neighbor install Avast antivirus on her Windows 10 Acer computer. This machine was upgraded from Windows 8.1.
She is using a Vizio HDMI television for a monitor with the video output of the computer connected to the HDMI input. With the screen resolution set to 1280 x 720 the screen looks correct as far as aspect ratio, etc. However, when attempting to open the Windows Defender App, I get a message telling me that the screen resolution is too low and the program will not open.
I right-clicked on the desktop and clicked Screen Resolution and set the resolution to the recommended value of 1920 x 1080. However, when I did this the screen content expanded and the icons on the left side and the taskbar on the right side were off of the screen. This is the opposite of what I would have expected; I would have thought that with the higher resolution that the screen contents would shrink since the same number of pixels would now appear to be compressed together. How can we increase the screen resolution and keep all of the screen contents visible?
(I hope that this isn't a dumb question, but I don't run Windows 10 on my own computer, so I'm not all that familiar with it.)
