Hello, I'm using the external iiyama 24" lcd with my MBP. Today my laptop stopped detecting the monitor; blue screen and monitor goes to sleep. I checked Detect Displays no results in System Preferences/Displays. I plugged the lcd to another laptop via Hdmi-Hdmi and all ok. I also re-installed system on my Mac. Can you pls help me ? Is it the Dvi / motherboard issue ? What else could i check ? I have an eye problem and need to use bigger screen. Thank you.
