If anyone could help me, I'd be very thankful. I've been hooking up my 2012 MBP to different TVs for about 6 months now. The display is fine on a typical modern 16:9 TV, a little cut off around the edges but not a big deal. What is far more frustrating is when I attach it to an older CRT 4:3 TV. I have never been able to get the display right, the issue is that everything is pressed together such that a O appears more like () if that makes sense. Circles look like ovals and faces look far too skinny. I have just upgraded to Yosemite and I still can't get it to display properly on a 4:3. I know that there should be letter boxing but I can't get such an effect to happen. Thank you to anyone who can help.
