i got a basic computer at job but 2 screen could be nice , so my question is: Can i plug 1 monitor into vga and the otherone in HDMI to have 2 screens ?

Unless it has a video card that supports two monitor output, the redundancy you see on the back is likely for single monitor support.

thats what i thought

thanks

You can use the computer information to determine if it is supported, or just list the stats here.. otherwise, trial and error Plug in a 2nd monitor and see what happens.

Do you have a GPU installed on your work PC? If so go into your device manager and let us know what model it is, whilst you're at it check your motherboard model as well since some onboards support
dual-monitor setups too.
