Black screen since attempting to use 4K

Apologies for using any terms or lingo improperly here.

Using a Roku device with a Sony Bravia tv for a long time.

Yesterday went through the Roku’s video output settings and changed from 1080p to 4k. Was shown a warning that my tv may not support that format but I was allowed to proceed anyway. Since selecting that option, Roku screen is black. All connections are firm and have been redone. Otherwise the tv itself and other inputs work fine. I assume this has something to do with the change I made. Problem is I don’t know how to undo it. Any tips or insight welcome!

Re: Black screen since attempting to use 4K

If all else fails, you can try to adjust the Settings > Display type setting when you can't see the screen. After booting up the Roku and getting past the bouncing letters startup display:

A• Press the remote Home button 2 or more times (Makes sure you're on the home screen at correct position with no screen saver running)

B• Up (Go to Settings)

C• OK or Right (Go into Settings options)

D• Down 3 times (Highlight Display type. It passes through Theme on the way and this may take a few seconds before moving on) so wait 30 seconds or so before continuing.

D• OK (Chooses Display Type option)

F• Up (Moves off current Display Type setting to next one up)

G• OK (Selects this Display Type setting)

At this point, the Roku will try to use the selected Display Type setting. The TV may take a few seconds to adjust to this new setting.

If you see a picture, click the "Yes, looks good" button to lock in this setting.

If you don't see anything, wait about 15 seconds, then hit OK to click the unseen default "No, there's a problem" button to return you to the menu.

H• If you have not found a resolution setting that works, repeat steps F and G to try the next Display option. Repeat until you find one that works.
