I have a 13" MacBook Pro and my external monitor would constantly flicker on and off while I was working. At first, I believed it was a problem with the input jack on the Macbook, so after much fuss with that, I decided there was another issue.
Eventually, this is what solved my problem - I simply switched the refresh rate on the external monitor from 75 hrtz to 60 and the problem was instantly fixed!
Hope this helps!
Exact same symptoms here... New MBA and a philips tv via thunderbolt-hdmi adapter
I get intermittent flicjer followed every few times by negative green distortion
Ive tried changing refresh rate to 60hz, output from ntsc to PAL
Any thoughts?? Could it be proximity of the laptop, tv and time capsule?
macbook pro 13, i7, thunderbolt.
External tv: Philips 32 tv connected through thunderbolt/hdmi is flickering, also screen turns negative-green then automatically returns to normal. Every more-less 15 mins.
Must mention that Dell external monitor works absolutely perfect.
I am already updated to the newest fixes through software update.
hopefully we get soon a fix to this.
10.9.2 and is still flickering? OMG..
Try changing the refresh rate. Go to apple > system prefrences > displays > select the ACD display and from here try to work either on lower Hz refresh rate or try different values at the ACD resolution.
Where you using the same cable, ACD, mbp before the filckerings came up? Might be a damaged cable or adaptor?
Sometimes before the major update on os x HDMI option, the HDMI transfered audio and video (instead of only video now). Go to system prefrences and check the audio source (and output) if they are at their normal settings while the ACD is connected.
