The HD in my 2011 27" started making clicking noises and showed other signs of imminent death. I decided to replace it with a solid state drive. I found an online video showing how to disassemble the iMac to access the HD bay. Unfortunately the power supply cable on my iMac was much shorter than shown in the video and I accidently broke the socket on the logic board where it plugs in. This can be fixed, but it won't be cheap. Apple is supposedly geared up to release a new iMac later this year and I am somewhat loath to investing a lot of money in a computer this old. My thought is this. My cheapest option would be to buy another 27" monitor and just basically forget about the iMac internal display (it is pre-Retina). The iMac has 2 Thunderbolt jacks, which I think are compatible with Display Port. Will this work? Trying to avoid throwing good money after bad, I don't want to buy the new monitor and cable and find out you can't get it to work if the primary display is inoperative. Any help much appreciated.
