I need to do presentations because iīm a teacher and the problem is that with some projectors and monitores connected to the external vga donīt show the correct resolution.
Iīve tryed with my test monitor that is a Samtron 55E and the image is bigger than the monitor. Iīve tryed to low the laptop resolution to 1024x768 and image on the monitor inceased. Iīve tryed every resolution from the laptop but i couldnīt fit the image correctly to the monitor.
Today i've tryed with a Epson projector and it worked fine just by setting the screen resolution to 1280X1024.
Afterwards when i was teaching, the Sanyo projector (that was in the classroom) didn't work at all. The resolution of the image were very low and i got huge images. Changing the screen resolution to 1024x768 didn't work at all. It gave an eaven bigger image.
My laptopp is a Thinkpad R51 with a ATI 9000 M7 LW. I can't install the fglrx drivers and i don't know why.
Code:
The problem i reported earlier is that i finaly discover that for some projectors the output to the projector is 640x480 and others is about 1024x780. Recently i tried on a 2 years old Compaq and it was working at 1024x780 an the next day i tried a Toshiba with 2 or 3 months and only get 640x480.
so my question is: What should i do to control the output to the external VGA. Can it behave like a 2nd monitor even using a multimedia projector?
Can anybody Help me. This is VERY IMPORTANT to me. That's my job.
