It's a total newbie question: I am installing Octoprint on Raspberry pi 4 and just wondering if I need additional computer screen, keyboard, and mouse - or, when I connect Octoprint to my network, can I just use my existing computer screen, keyboard, and mouse?
I've seen different videos saying different things, such as you need to hook a computer screen up to the HDMI ports. I'm just trying to get everything set up in the easiest way possible. Thanks for any help.
What did you already try to solve it?

Have you tried running in safe mode?

Systeminfo Bundle
You can download this in OctoPrint's System Information dialog ... no bundle, no support!)

Additional information about your setup
OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ... as much data as possible
You can setup a Pi 'headless', which means nothing attached to the ports (no screen, mouse or keyboard). You put your wifi config on the SD card, or plug the ethernet cable in to get it connected to your network.
Once everything is setup & connected, then the Pi is a server and you can load OctoPrint's UI in your browser. To access the system, you can use SSH to remote-access to the command line.
The only time you may want a screen attached is if the wifi connection is not working and it needs troubleshooting, since obviously you can't remote access if it's not connected.
Correct, that's all you should need. As for the USB cable, we just suggest that the cable is thicker (usually means it is higher quality or better shielded) and like you say, not a cheap thin one that is likely to have interference etc.
Echoing Charlie_Powells post and also get a USB cable that as short as possible. BTW you don't even need an ethernet cable if you have Wifi (newer Rasp models include WiFi).
No issue with ethernet cable length, I posted re. USB cable length, the shorter it is the less noise sensitive it will be..FWIW I've always used Wifi with Octoprint. About the only thing I wouldn't risk to Wifi, would be flashing printer firmware (based exclusively on personal prejudice).
12 foot ethernet cable is OK. 12 foot USB cable.... That is longer than most USB cables I've seen. My USB cable is about 15cm, if that. Be aware of issues.
