Ask Mac Questions and Get Answers from Experts ASAP
I am having a problem with connecting my macbook pro to my tv with HDMI. Every time I connect it, it says resolution mismatch. I have tried connecting my mac book to all my other tv's and it woks fine. i have a 39 inch magnavox tv. this is a problem because i use my mac book in clamshell mode 98% of the time.
I'm sorry, I forgot to mention I rest the PRAM yesterday and that did not work. I have also already deleted the "Windowserver"files
Processor: 2.3GHz intel core i5
Memory: 4GB 1333 MHz DDR3
when its connected to the TV:
What model MacBook is it? Can you give me the serial number?
Macbook Pro 13 inch, Early 2011
it is still giving me the message "this tv does not support the output format, video resolution, or refresh rate of connected Device"
it is still only working when that laptop is open but not in clamshell mode
Yes several timas
would reinstalling mountain lion delete all my files?
hello, so last night I reinstalled mountain lion and that did nothing to help. Today I was using my macbook outside, and when I brought it back inside and connected it back to my TV it worked for a moment in clamshell mode and I could use the screen, but then It went right back to displaying the " resolution mismatch" box.
yes unfortunately we do. Thank you so much for all your help.
