how to put graphics on a monitor in gmod with lua?

So I have this code

and I want to be able to draw stuff on the monitor’s screen like in gTerminal.

With such a vauge question, I think you’re not really ready for something like that. But whom am I to say that, have a look at gTerminals/DarkRP’s code, they have some 3D2D methods in there. You can also use rendertargets I think.

I cant find gTerminals code anywhere but where would I find it in DarkRP’s files?

Money Printers, Microwaves, Shipments, etc inside cl_init.lua
