Q: Mini DisplayPort just stopped working

Hi

Have been using my MacBook Air 13" 128GB 2013 for almost 2 years now, bought it in August 2013.

No problems but in the last 3 days have been having major problems with the MDP connections to VGA, DVI & HDMI monitors, it, very rarely, picks them up.

I'm using Belkin leads and adaptors and it is happening on equipment at work, I am a school teacher, and at home on a large variety of video outputs - data projectors and monitors.

Please help as this is kind of my bread and butter please tell me I won't have to replace my MacBook, as it is a great machine, and I have got it set up perfectly for me (+ on School Teacher money really can't afford it!!!)

Cheers

Steve
