VS228H-p 21.5 inch monitor while the other is HP LV1911 which I'm pretty sure is a 18.5 inch monitor (it is def smaller than the other one). A few weeks ago I bought a second screen, I also had to buy a VGA to USB port (FrescoLogic FL2000 USB display adapter) because I don't have a second VGA port on the back of my desktop.
For the longest time I've just had one screen.
