Everytime I start up, log in, wake from sleep, etc. I have to open display preferences to adjust the size of the screen so that I can see it in its entirety (see screenshot). The display prefs are not being saved at shutdown. Also, the screen size adjustment slider doesn't always appear as an option (see preferences in screenshot).

o This needs to be set up on your TV
Get out your User Manual and set the mode to "Dot by Dot"(Full Screen)
If you have a hard time finding that obscure setting, download the Owners Manual and do a search.
Now your M1 BigSur Display Setting: "under scan slider" will be at zero with a full display.
Most TV HDMI inputs can be set to different modes, just keep that in mind when swapping locations.

Thank @Zephuros2000
He solved it first, "full pixel" if I read the thread more carefully, I'm sure I wouldn't have even commented. I'm so excited they finally fixed the virtual keyboard, shift/caps issue after 10 years :)
Addendum: The display issue continues, but with improvements after the latest Big Sur update (11.2.2). While the display still needs the occasional touch-up after the system fails to return it to the correct fitting, the overscan/underscan slider bar now appears reliably in the Display settings of the System Preferences.
Thank you for keeping us posted on this display issue.
Even my little "trick" stopped working.
I miss my menu bar.
I thought I was replying to skkyup's Jan. 11 suggestions but my post didn't show up in the right place.
I recently upgraded on 11.2.2. I'm on an m1, with a 32 in monitor. The zoom issue still exists...
FYI
Wow ! Here's whats interesting. My Tv is a 32" but its showing as a 25inch. The model # is exact. I dont see people in an uproar over this, so is it possible this only affecting SonyTv's ? Im clueless because I don't have another tv to test it on even temporarily.
Same exact display #...above and below proof
I played wit it for 5 mins then it magically goes back to normal.
^^^Notice my menu bar and dock is not** cut off and it apppears as should. Then i restart and...it looks like this....
^^^Notice my dock is cut off and i cant see my menu bar at all ! ! This is the crisper picture resolution that i would love to use if it worked correctly =(
^^^^ Went through video and advanced setting. Enabled "low latency" aka "Game mode'. Made sure im set to "normal" on aspect ratio but did not have a 'full pixel' option that you speak of. Even checked 'Advanced settings'.
^^^^Even bought a new HDMI cable but nope ...no luck.
Try this 'trick' to get the correct ratio on startup. Follow specifically these steps.
1)Make sure mac is OFF.
2) Turn on TV..make sure it is on your Mac 'input'.
3)Turn OFF**** Tv. Make sure it stays off.
4)Power on MAC** you will the hear the startup noise or look for the light to make sure its on if you disabled this feature. Remember TV is OFF** while doing this.
5) Wait 60 seconds. Do NOT** do anything yet.
6)Power ON** your TV. You will now be at your login screen. Enter password.
7) Your aspect ratio should*** be perfect now.
--Please note you will have to use this method everytime you power on. I have found this works for me although it is a temporary and rather ridiculous solution. On a restart or shutdown with tv on** it will just go back to trash style. aka cut off docks, hidden menu-bar, cant see wifi strength icon, etc. I hope this helps. I just wasted 2 hours of my life figuring out WHAT APPLE CANT. They should hire me lol.
I just clicked your username and 'followed' you and 'followed' this entire thread as well so I will get email notifications. Hopefully other people can help us with this issue. The site does not seem to get much traffic and many posts are simply left unanswered. I hope somebody will help us and soon. I just bought this TV last black friday and planned on continuing to use it.
