I am using the pi hole for DHCP, maybe you just have to turn off the DHCP server on the att modem.

Are you sure about that? I’m using the official AT&T fiber modem (Nokia white oval) and a pi.hole for DNS. I do remember needing to change a number of settings to get it to work though.

You probably want commercial displays. They’ll cost a bit more, but they’re also designed to run 24/7 (think the screens they use in menus, signs, etc) so they could probably last forever as a TV.

Windows Co-pilot just popped up on my Windows 11 machine. Its disclaimer said it could provide surprising results. I asked it what kind of surprising results I could expect, it responded that it wasn’t comfortable talking about that subject and ended the conversation.

You can get both HDMI cables and DisplayPort cables that are USB C on the other end. These will plug directly into the USB C ports on the laptop without any docks or adapters involved.
