You might give that a try and see if it works better after boot of the OS. The anaconda drivers are a subset of the drivers for the distro, so it might work better after initial. Might also try one of the LiveGnome or LiveKDE isos. -------------- next part -------------- A non-text attachment was scrubbed...

I did try Basic Graphics before, and while it made the image clear and distortion-free it was still 640x480. While browsing bugs.centos.org I saw a reference to using "vga=773" to fix the resolution in VMware Fusion/Workstation, but it had no effect on the physical server's GUI when I tried it. The same bug post mentioned putting "text" on the kernel line. I didn't think that was supported on CentOS 7, should that be in the Troubleshooting menu too? I'm using that to get the server at least basically loaded for now, I'll go back later and tweak the auto-generated KS file to re-install the way I want it.
