My M2000 has some screen burn. Still works but pretty annoying to see. Is this permanent or is there a way to even out the display?

Also, will keeping brightness to a minimum extend display life?

That is a typical VFD effect. I have reduced the brightness to about 75% since the first day I would say and the displays of my two M2000s look still good. But I have two Radios R1000 where the screen pixels of the typical used areas are clearly visible dimmed.

The effect is irreversible. Reduce the brightness of the VFD to give it a longer life time.

One other trick with the M2000s, is to go into configuration and set the date display to Long Day/Month/Year & the time to 24 hour and then select the largest available font (ZurichBold32) from the remote - this uses a greater proportion of the display for a greater portion of the time whilst the M2000 is in standby. This will cause more even wear across the whole display area. I also turned the brightness down on all of my SB units.

My M2000s both have a brightness of 0 in standby, the screen is blank. This not only prolongs the life of the display, it keeps the device noticeably cooler to the touch.
