I upgraded from 7.3 to 7.4 over the weekend. Everything went well except that I can't login because the screen is black with a cursor.
If reboot boot the 7.3 kernel 3.10.0-514.26.2.el7.x86_64 kernel everything works just fine, so my guess is that there's a kernel issue with the hardware, specifically the Skylake processor.
Has anyone else run into this problem and if so can how I resolve the problem other than using the previous kernel?

Any help with this would be greatly appreciated.

Pete,
I have had various assortment of problems with 7.4 to the point that I quit upgrading the rest of our PC's with 7.4 until the problems are identified and fixed. The only work around that I could come up with is to use the last 7.3 os which at least made each unit usable.
As you know, most of the time these upgrades have been seamless because the Centos team has done a wonderful job. However, the upgrade to 7.4 has some problems, and I decided to stop the upgrade of our remaining units until 7.4 works as well as 7.3.

Greg, I've done 5 upgrades so far without any issues. This is the first one that has a problem and after some experimenting it looks like the kernel is identifying both the analog and digital ports and making the digital display the primary. I use a KVM switch and needless to say it's a royal pain to have to switch back and forth to accommodate this one host. Like you I settled on using th3 previous perfectly working 7.3 kernel, not optimum but it does work.
I've also decided to get a graphics card in lieu of the on-board graphics card in the hope that that will solve the issue with the 7.4 kernel.
Agreed you do get used to these upgrades working seamlessly and it's a bummer when occasionally things don't work out exactly as planned.
