In-person DMs: how do you actually get the battle map in front of your players, and what's the most annoying part?

I run games in person and I've never been happy with how I show the map to my players. I've done printed tiles, a laptop turned around, a TV on the table, and plenty of pure theater of mind. Each one has a catch: printing takes forever, the TV means my notes are on the same screen the players can see, and hiding rooms is always fiddly.

I recently built a battle map with fog of war that streams to a separate player screen (a second monitor or their phone), so I can move tokens and reveal rooms on my side while the players only see what they've discovered. Building it made me realize how differently everyone solves this, so I'm curious:

How do you show the battle map at your in-person table right now , TV, tablet, printed grid, or theater of mind? And what's the single most annoying part of your setup?

Also, for those who bother with fog of war at a physical table: is it worth the hassle, or overkill?

Genuinely trying to learn how people handle this. Happy to share what I built if anyone's interested (link in a comment so I'm not spamming).
