iMac slows down to 10% when no LCD present
Imac 27 2012-2014 Slows down when no LCD present
- I am using external display (any DP, HDMI or DVI connected to TB port)
- diagnostic LEDs 1 - 3 are ON,
- diagnostic LED 4 - OFF (no communication GPU - LCD panel, LCD not connected)
after running performance test all result seems to be 10% of default results when LCD is plugged on (connected with backlite and video data cable)
How to avoid iMac running at 10% (Geekbench 3 for i7 4.0ghz 407 ; 1408 (32 : 64 bit) when LCD is NOT present?
Thanks for answer or hint!
