Up until now I have connected my MBP to my LCD TV via VGA cable to the adapter that goes from VGA to minidisplay port. I have a small 5 or 6 foot VGA cable that I was using. Once I connect it, my MBP display goes blue and my LCD TV becomes the monitor and everything is calibrated automatically - it just works with nothing to set overtime.
Last night I went to tiger direct and picked up a 15 foot VGA cable so that I could sit on the couch and operate the computer for movies etc. I hooked it up and t was as if the screen resolution went to 640x480 and I could see this on both the MBP and the LCD TV. I changed resolution to the max and it was still mirroring both displays. Even at the 1900 x ??? setup it didn't look right. On the TV the screen was moved over to the right so you could see a 10inch black bar along the left side, along with a flashing pinkish line along the bottom. All the TV would let me do was move the screen over to the left to centre it, but not expand it to fill the screen. I plugged in the old cable and it looked perfect again, I plugged in this cable and same problem. I went back and forth and same results..
Is it the cable? is there a certain length of cable that would cause this? is it something else? I've never had to calibrate my TV before..
in looking on the site it seems the cable I got has a lower resolution than other ones..
this is the one I got
