Hey guys, I recently purchased a 07KGN Rev. 1.0 motherboard with the dGPU and beefier heatsink. I installed it into my E6440, but my display isn't receiving any output. I currently have the 1366x768 panel. It doesn't seem like a backlight issue because my screen just stays fully black, there's no dim imprint or anything. I did plug it into an external monitor via the VGA port, and it works fine. The BIOS (revision A23) didn't recognize it has a dGPU, it just said integrated graphics. However, when I booted into Linux, it recognized that I have the AMD dGPU installed and I could download drivers for it. I personally think it's a problem with the display cable. Anybody got any idea what's up?
