Monitor flickering when in certain websites, and then turns black.

Macbook Air 13", Early 2014, 1.7 Ghz Core i7

120 SSD, 8GB Ram, OS X 10.9.4

External Monitor Compaq W185q

Hello all, I know there are similar questions out there, yet not the same problem!.

I'm using an external Monitor (Compaq W185q) and everything's ok until I open certain webs, this websites have banners on both sides mostly, so I think that's important to tell. After couple seconds on those sites, the monitor starts flickering and then it turns black, completely. To make it work, I launch Mission Control and it starts working again, I drag the safari window back to my MBA's monitor, and problem solved.

Can you guys give me some guidance on this? It's making me waste time moving from monitor to monitor.

Thank you so much.

MacBook Air, OS X Mavericks (10.9.4)

Howdy iMWorks,

It sounds like the issue you are experiencing is only happening on your external monitor, but the video works fine on your internal display. I have a couple of thoughts as to what could be causing the issue here. First, use these troubleshooting steps to help troubleshoot the hardware, and PRAM:

Apple computers: Troubleshooting issues with video on internal or external displays

http://support.apple.com/kb/HT1573

Try unplugging the video adapter or cable and then plug it back in.

If more than one video adapter is in use (or "daisy-chained"), troubleshoot by using only one adapter.

Example: A mini DisplayPort to DVI adapter connected to a DVI to HDMI adapter is an unsupported configuration because there is a series of adapters in use.

If available, try using a different display and or adapter (or use a different connector by using DVI instead of VGA, for instance).

Reset the system

You can reset the Mac's parameter RAM and SMC.

Reset the resolution

Start by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:

Start up in Safe Mode.

From the Apple () menu, choose System Preferences.

Choose Displaysfrom the View menu to open the preferences pane.

Select any resolution and refresh rate that your display supports.

Restart your computer.

If the issue persists, I would use the following article to troubleshoot the Safari application on the computer:

Thank you for using Apple Support Communities.

Take care,

Sterling
