i have been using a matrox g450 with 4 monitors for 5 months now. No problems. but i just moved and when i tried to hook them back up. I can only get 2 monitors to work. I remember having problems when i first put in the new card. but i cant figure out what i did to get all 4 monitors working at one time. when i go to settings I only see 2 monitors and the drop down menu only lists 2 monitors....I have tried everything...can't seems to get it to work...I seem to remember that it was something simple that I did ...like just checking or uncheck some box...please help i am going crazy M
1) are your cards installed properly? 2) do you have all the drivers working properly? 3) re-check the cable connection
Isn't the G450 a dual head display? Unless you have two G450 I don't understand how you can get 4 monitors connected either.
