How to save underscan setting

I use a TV for my 2nd monitor with my MacBook Air. I have to apply a little Underscan to see the menu bar at the top of TV. Until recently, that Underscan setting would always be saved when I disconnected my laptop and/or the TV shut off from lack of signal. The only time I had to reset was when I restarted my computer.

Now, the Underscan setting reverts to "Off" every time I disconnect or the TV shuts off. This seems to have started happening after I did the last update. I'm running Ventura 13.4.
