2Everything you wanted to know about video options in config.txt but were too afraid to search for – Jaromanda X Mar 13 '19 at 01:01

A 4x3 is 4 pixels by 3 pixels, how small do you want this screen? – BlackOps-9-Elite Mar 16 '19 at 17:21

@BlackOps-9-Elite 4x3 is the aspect ratio of the screen, not the pixels. In other words, the ratio of width to height. – Benjamin Ashbaugh Mar 16 '19 at 18:29

You shouldn't need to configure anything. Because you said you have a HDMI to DVI adapter, I am assuming your monitor is DVI. So just plug the pi's HDMI into the monitor (using the adapter) before turning the pi on and then turn on the monitor and then the pi and it should work.
If it doesn't you may need to force the HDMI connection. Put the SD card in your computer and edit the config file in the boot partition, as described here.
More ways to edit the HDMI configuration can be found here. (Thanks, Jaromanda X.)

that's rather sparse info in that link ... https://www.raspberrypi.org/documentation/configuration/config-txt/video.md is where you get real information :p – Jaromanda X Mar 13 '19 at 01:01

4:3 1280 x 1024 computer monitors will work because i have used my raspberry pi with a 4:3 1280 x 1024 computer monitor before and it works automatically with no configuration and i used a hdmi to vga adapter because my monitor was vga only

1Agree. I use a screen with the same geometry and a simple HDMI to DVI cable – Dirk Mar 14 '19 at 11:39
