You should be able to change the refresh rate in System preferences- Monitor. This is an example of my HDMI to HDMI connection. You can try using the SwitchResX app to see if that will work. FYI: Something is happening with Mavericks and external display (similar to yours) but I am not qualified to talk about what.
I had the same problem. went to system preferences, open sound, output, selected my samsung tv as output and it instantly switched sound from laptop to tv.
DVI does not pass through sound, just video. You will need to use a separate cable for the sound.
DVI (DVI = Digital Visual Interface) does never carry sound, it's visual only. Buying a Mini Displayport to HDMI does not help you out either because it's not supported for your Macbook Air. Here's the list of laptop models that support audio pass-through via MDP MacBook Air 11" Model 3,1 MacBook Air 11" Model 4,1 MacBook Air 11" Model 5,1 MacBook Air 13" ...
No, the iMac should auto-detect the external display when it is connected. I'd try, in order of presumed difficulty: Make certain the correct input is selected on your display. The lack of audio makes me suspect there's an issue there. Make sure your display is set to use the Line-in jacks instead of the HDMI audio stream. Boot the iMac with the external ...
Have you tried a different HDMI cable? I recently experienced a problem with a Roku 3 that sounds similar. During boot, the Roku displayed its boot screen successfully. However, once it got past that point (I assume it switched video modes,) the display went to flickering black with rare bursts of proper video. I replaced the cable (after constant ...
Have you tried all the refresh rate settings? I have seen similar problems when operating at a resolution beyond what the TV (or graphics card?) is capable of. Cycle through every resolution setting and each refresh rate available at each resolution. If it is too hard to control the display dialog box do "gather windows" on the main display and you can ...
You did not tell if you tried using your Macbook and the Griffin cable with other kinds of external monitors (i.e. projectors, computer monitors). I had flickering problem before because of poor cable contact. From what you described, I would focus my suspect very much on the Macbook mini display port and image setting. Just an idea, you may try reducing ...
I cannot comment your question, but maybe you can narrow the problem down by using gfxCardStatus to force the macbook to use either internal or discrete video card. I'm thinking it may be a problem with either. Also, can you get rid of the flickering by forcing the plugs a bit in any direction with your fingers?
