Dell L322X sleep problem

Hey guys, I finally got my first hackintosh working. It's a Dell XPS L322X with an i5 and intel hd 4000 (1366x768).

Followed this guide exactly to set it up, except I used the 1366x768 plist file given by a user: https://www.tonymacx86.com/threads/guide-dell-xps-13-l322x-el-capitan-clover.198312/

Everything works properly except sleep. Whenever I put it to sleep, it goes to sleep. But when I wake it, the keyboard backlight and power led turn on and I can hear the fan spinning, but the display stays black (it doesn't even turn the backlight on).

I've searched and tried setting darkwake to no, 0, 1, 2, 4, and 8. And hibernate mode to 0 and 3. Neither setting works. And help or tips would be appreciated, thanks!
