The screensaver "Word Of The Day" works fine on the built-in laptop display. It runs slow and messes up the screen if I use my external HDMI monitor. Unplugging it does not help: the laptop screen remains black and flashes once in a while but there is no way to get back to the desktop.

I'm not too excited about OS X screensavers but this probably means I've got something messed up which will bite my ass later:

Your ioreg shows no HDMI device plugged in.
 
Errr....That would be from my forgetting to plug the monitor back in.

I don't know if this is the cause of your issue, but the port that is associated with your HDMI is not patched for HDMI. It still shows connector-type <00 04 00 00>, which is DP. Should be <00 08 00 00>. Patch the framebuffer as required... (see HDMI audio guide from FAQ).

Also, you might try other ig-platform-id values... (for example, 0x191b0000).

Err...is there a list of all the HD530 ig-platform-ids? I went through a whole bunch of them and QE/CI only worked on 0x191E0000. Just assumed that it had to be the right one.

So looking at my ioreg and the guide Intel IGPU HDMI/DP audio (Sandy/Ivy/Haswell/Broadwell/Skylake), in order to change the connector-type, I have to patch the 0204 connector in AppleIntelSKLGraphicsFramebuffer. But there is no patch in https://github.com/RehabMan/OS-X-Clover-Laptop-Config/blob/master/hotpatch/config.plist for Skylake.

You can extract them from the framebuffer kext binary.

I look at the framebuffer connector data for 0x191e0000. The 0204 connector is:
02 04 0A 00 00 04 00 00 87 01 00 00

To patch it for HDMI:
02 04 0A 00 00 08 00 00 87 01 00 00

Applying this patch (in config.plist) fixed the screensaver crash with HDMI monitor.
