right click on garrysmod (in the steam menu) -> preferences -> set launch options, then put in the following:
-dxlevel 90 -width 1440 -height 900

i wanna say that i contributed that, since im the only one that i know that uses that resolution >_>

for the record, instead of putting 1440x900, you should probably put your actual resolution lol
another thing that should be put in there:

if you have a problem on connection with a server that says something along the lines of "Buffer overflow in net message" here's what you do.
Go to C://Program Files/Steam/steamapps/ACCOUTNAME/garrysmod/garrysmod/cfg create a notepad file called "autoexec.cfg". Inside that file simply put the following code (without quotes) "myinfo_bytes 8192".
Save that file as a .cfg file and close the folder.
Problem solved.
