Recently, several times a week, the Apple Display has been going completely dark, forcing me to restart Mac Studio. The problem worsens if I leave the computer idle for extended periods. This issue started after the Tahoe upgrade. Any suggestions?
Mac Studio, macOS 26.2
<< swapped to another original thunderbolt cable. >>
ThunderBolt cables for use with such a high-resolution display are limited to
• the Apple pre-engineered 1 meter cable shipped in the box, or
• a certified (Thunderbolt logo on each end) Thunderbolt cable 0.5 meters maximum length
... for reliable operation.
Longer Thunderbolt cables can be had by purchasing an ACTIVE Thunderbolt cable, but they are much more expensive (staring at US$125).

"cheap" things to try.
consider giving your display timeout:
disconnect from all power and data, and leave it by itself for a quarter hour.
(Pointing it into the corner, or making it sit on the naughty stair is optional.)
This allows the display to reset itself.
Be sure to let Readers know if that changes anything.
Having similar issue for past couple of weeks. Studio Display goes black, thought randomly at first, now think may be when switching applications. Am using original thunderbolt cable & OS is current. Did all the usual troubleshooting (e.g., restart computer & display, unplug display 5 then 30mins, swapped to another original thunderbolt cable). Called Apple Support, then took everything to a Genius Bar appt where, of course, it worked fine! Diagnostics on computer & display found nothing. All seemed fine for a couple of days afterwards, then started going black again. From online suggestions, tried turning off Displays Have Separate Spaces & Stage Manager settings. At first thought that worked, but it didn't, although it happens a lot less than when these are on. Help!
I presume you mean an Apple Studio display.
are you using the same pre-engineered thunderbolt cable that shipped with the display?
Greetings and thank you for your reply. Yes, I have the Apple Display connected to the Mac Studio with the original cable that came in the box.
Both cables I've used are the original cables that came with the Apple Studio Display. (My husband and I both have displays, purchased at the same time.)
Apple Studio screen turns black!
