Change display size on screen help

Question

So I am making a media player with my pi4. I have the housing I want to use to hold everything. The issue I have is I cant find a display the size I need. I need 1.5" x 4" LCD. This is the closest I can find.

C$ 30.82 23%OFF | 5.5 inch 2k 1440*2560 IPS LCD Screen Module Display Monitor Hdmi to Mipi board

Is there a way that I could use that screen but change the display area?

I made the following changes in the /boot/config.txt file, to support my 7" TFT LCD (or any size for that matter). Uncomment "disable_overscan=1" overscan_left=24 overscan_right=24 Overscan_top=10 Overscan_bottom=24 Framebuffer_width=480 Framebuffer_height=320 Sdtv_mode=2 Sdtv_aspect=2 Just pick the item's value you want to fit yours. May take a bit of playing around. I used this video as a guide. Hope that helps. Clem
