Logitech C920 webcam flickering on XPS13
The picture starts OK when the laptop is turned on but after a few minutes starts to break up, see video
https://youtu.be/D-UC1FWHsWQ
I've tried
-
Disabling USB Selective Suspend in Power and Settings app
-
Disabling "Allow the computer to turn off this device to save power" for all HID devices and USB controllers in Device Manager.
-
Updating the Logitech drivers
-
Swapping from the Logitech driver "HD Pro webcam C920" to generic Microsoft drivers "USB Video device"
Nothing works.
The C920 works well on a different Windows 10 laptop. The inbuilt webcam works.
Has anyone seen this and does anyone have a fix?
many thanks

I don't have that software, what is it called?
I have very simple Logitech Control software which has an option for NTSC (60Hz) or PAL (50Hz). Swapping those makes no difference.

Answering my own question. Just as I was about to send the C920 camera back to Amazon I tried in the other USB-C socket on the Del XPS13.It works. No flickering, no shearing, no break-up.I've no idea why the two sockets should behave so differently.daemoncycler

Hey, thanks for that. Fixed my flickering issue too. Not on a Dell PC, however.
I have had several tho, Dell PCs' that is. Still have & use a 2008 Latitude (Dual Core) & 2009 XPS 435MT (i7-950).

This answer will seem obvious when I state it, but I had to re-trace my steps a little to think of it.
My 920 started to jump and flicker on a Zoom call.
- uninstalled ManyCam to see if I had messed up a setting - no change
- installed Logi G Hub and change the anti flicker setting - no change
- ran USB extension cable and plugged cam directing into different USB port - Success
Why had this suddenly become an issue?
Initially the cam was plugged into a passive USB hub but worked fine. It shared the hub with my Keyboard. However, by Bluetooth mouse quit the other day and I had to use a USB mouse. My theory is the power draw was a little too much with both cam, keyboard and mouse all plugged in to the same hub.
I know this sounds simple, but remember troubleshooting a random computer reset issue at work years ago. It was caused by a laser printer that was only used when another staff member was in the office 3 days a week. Printer would power up and caused another person's computer to 'randomly' reset.
Hope this helps some.
