Freeze when connecting to monitor

I have the exact same problem with my MBA and both Sony and Samsung HDTVs.

The TV shows up in the display properties and the MBA besomes very slow. The TV shows no signal and I have ti unplug my adapter for the MBA to become responsive again.

Any response here? I am having the same exact issue, though I will admit, I have an off-brand Mini-DisplayPort -to- VGA adapter i got off of Amazon.

Ended up getting one from the Apple Store and it works on everything I've tried so far, 2 TVs and a projector.

This is an older topic, but I'm having the exact same problem and haven't found a solution yet. I'm also using a third party adaptor made by a company called V7. I know it's third party, but I don't see any reason why it shouldn't work when the thing was made to run with Apple computers. Why should I have to buy the more expensive Apple-brand everything just to use perhiprials with my computer? I'm beginning to think that the "plug in anything and it works immediately" mantra that Apple fans like to throw around is a load of crap because I've had problems with nearly every external device I've attempted to use, from MP3 players to midi keyboards.

Sorry for somewhat ranting, but I would like some advice. Does anyone have any suggestions? Maybe some settings I can play around with?

If it is Apple branded take it back to Apple.

If it is a 3rd party device you'll have to work with them.

Apple is usually a more stable environment because the number of variables are smaller. When you go to test a Mac with Apple branded equipment their QA team usually does a decent job of testing all the current models. This is possible because there are a limited number of current models to test with. It also means that Apple can take shortcuts in implementing new technologies that take other PC manufacturers to work together on to create a standard. PC laptops still ship with VGA on board. Apple has been using mini Display Port for years and is now moving on to Thunderbolt. The PC industry has just started talking about getting rid of VGA to standardize on HDMI as the laptop output of choice.

Start adding in 3rd party connectors connecting to 3rd party devices and it gets complicated in the Apple world.

If you can identify the V7 adapter, the Monitor and the Mac laptop model and year you are using it might help.

V7 is Ingrahm Micro's OEM brand. I would try contacting them for support since you are not likely to be on the only Mac user with a V7 adapter having issues

Same problem here with MacBook Pro.

At first, it worked fine. Monitor was detected and worked smoothly. After week or so same symptoms started to appear. But instead of slowing down, system goes to halt completely and the only way to start Mac working is to unplug adaptor and hold power button.

I'm using Macally mini vga adaptor. I have no intentions spending 50+ bucks on Apple branded adaptor as I do not see the big difference amongst them.

Hope someone can come up with solution.
