Hi, I tried this software. Doesn't work for me. Anyone has any other solution to wake display from sleep?Tip for anyone using HD 530 and can't wake display up after it sleeps - try this as a workaround:
I am using the Intel HD 530 via HDMI 2.0 to a 4k monitor, it is running very smoothly (with the pixel clock patch). However, as described in this thread, my machine can sleep and wake but the display will not receive any signal after:
If I screenshare with my hack using my MBP, I have found that changing the scaling/other display settings once or twice makes the display wake back up (as long as the display is not in power standby at the time - it seems to need to be powered on and looking for a signal).
- turning it off and back on again
- putting the display to sleep (including with a hot corner)
In light of this, I have found an app called QuickRes. It has a keyboard shortcut feature to toggle between resolutions of your choice. I am now using this after I have turned my display off, and back on, to force it to wake up, and it has been working successfully.
