Since the game isn't actually crashing it is most likely a configuration issue with your display as you stated. Some times changing the screen resolution from the options menu of EQ doesn't solve the problem. The same is true for changing the resolution in windows or your display drivers settings. There are times when the resolution changes must be made from the eqclient.ini file in the EQ directory. It may or may not work but I would certainly try modding your resolution from the eqclient.ini file.
Here is a link to another post that talks about making those changes:
