HDMI Video Freeze

[hrcx86]

Hi, I'm a newbie in the forum and in the Hackintosh world! First of all thanks for your support that allowed me to install OSX on my laptop using Clover (special thanks to Rehabman!)
My pc is an Hp 15-n207sl: Haswell based, I3-4200U and hd 4400 mobile 8086:0a16. I succeeded in patching my dsdt and ssdt (working audio, ethernet, stop mode etc.) (thanks twice to Rehabman!).Now I'm having issues with brightness control, end more frustrating I'm facing freezes followed by unexpected and spontaneous reboots after connecting the HDMI cable and I don't know where to begin So I need your help, please! Thank you all in advance!

PS: the video card is recognized by OSX 10.9.5 as "Intel HD Graphics 4400 1536 MB" and seems to work fine with full hd video streaming, dvd and video editing apps.

Post is off-topic. This forum is Lion. You have Mavericks. And a laptop... Open thread in Mavericks Laptop Support.
