Bought a Dell P2715Q monitor during JD’s 618 sale. This thing only has DP and HDMI. With my current setup, HDMI caps out at 4K 30 Hz, and 30 Hz is basically unusable, so a DP cable was mandatory. I had some UGREEN DP cables lying around from a previous JD order, so I plugged one in. Big mistake. The moment I connected it, the PC wouldn’t turn on. At first I thought the monitor was faulty, or that my GPU (an iChill 770 4G) couldn’t handle 4K. Then I tried a hot-plug and it worked fine, no problem at all. But once the cable was connected, the machine refused to shut down properly, and after shutting down it wouldn’t boot again. After a bunch of testing, I figured out that with this DP cable, the PC just won’t boot. And when it does come back, Gigabyte’s “Dual BIOS recovery” message pops up telling me one BIOS is dead and it restored from the backup.
