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.

MacBook Air 13″, macOS 13.4

I'm here searching for an answer to this as well. I want Apple to release a Sonoma update that saves the underscan setting.

I just started using a Macbook Pro M3 a few weeks ago and have the same set up (using flat screen TV for 2nd Monitor) and problem - ie. I have to reset the underscan every time I wake up the laptop. In other words the laptop is in sleep mode and when I wake it up I have to reset the underscan. Very frustrating indeed. It would be great if an Apple tech would weigh in on this problem.

I can tell you this bug has existing over several major releases now and Apple just doesn’t seem to want to fix it despite multiple tickets to them over the years. For the record, this problem still exists on a Mac Mini 2023 running Sonoma 14.3.1.

Apple Support had no answer. I am using a brand new (1 week) MacBook Air and an older Toshiba televison attached with an HDMI cable to a HDMI, USB and USB-C adapter. The same setup worked fine on my 1995 MacBook Air. Apple Support told me to try using a HDMI cable directly to the MacBook or get a new monitor. I really don't think the cable suggestion would work and I really don't want to invest any more money.

Any suggestions?

I wouldn't do either of those things. If it worked before clearly software is able to handle this, they just ditched the feature and of course need to tell you how everything OTHER than them fixing it will solve the problem.
