Hi, I recently tried to upgrade my El Captain installation to Sierra after noticing that Jake Lo had updated his guide to include an e6420 bootpack for Sierra. From what I can tell things are working so far except for one major thing. The screen does not work, it’s a black screen and I can only use the laptop via the hdmi out. I do not think this is a bios issue this time, because I saw that the bootpack was for bios version a23, so I updated my bios to a23 beforehand. My monitor’s resolution is 1366x768 and I am using the DSDT-LoRes from the new bootpack, but it would appear that the resolution that is being output, at least via hdmi, is 1360x768, maybe this is the reason why I am getting a black screen? I’ve attached a picture of my tv saying that the resolution is 1360x768, just to show where I got that number from. Any help would be greatly appreciated.
