Dell Inspiron 7577 w/ External Monitor
I recently bought a Dell Inspiron 15 7577 laptop with an Intel i7 7700HQ, 16 GB ram, Geforce GTX 1060 max-q, 128 GB SSE, and 1 TB Hard Drive. I've tried connecting this laptop to an external monitor (LG 24EN33TW) but I ran into a few problems. There would be blinking red dots all over the screen and the screen would sometimes flicker black, sometimes even staying black. I know the problem isn't the cable or monitor because when I connect the same monitor with the same cable to my desktop, it works fine. Does anyone know why this is happening? I use an hdmi cable with a hdmi to dvi-d adapter if that's important. Thanks

My external HDMI monitor stopped working two days ago after recent 1.4.2 BIOS update.

i have tried everything and the port doesn't seem to respond at all. The monitor, cable and even the port are just fine. Can this be a bios problem?

The use of an HDMI to DVI adapter/cable might be the issue. There are multiple threads with multiple users reporting that the XPS 15 9570 doesn't work with those adapters/cables, for example. Dell to my knowledge has not provided any insight as to why that system doesn't work with DVI displays (never mind committing to delivering a fix), and I was surprised to see this issue at all since I've never had a problem switching between HDMI and DVI in either direction on multiple systems and displays. But somehow that issue exists on that system, so I wonder if it might also exist on this system.
