Good day,

Thank you very much for your time and patience.

Did the live-view screen on the VLC media player work like this all the time, or randomly?

May I know the model number of your home router?

Are you able to test the RTSP stream on a different computer, or another RTSP program?

update:

At the same time, please try to refer to the following suggestions as well:

1. Turn off the Hardware Accelerated GPU: https://www.tenforums.com/tutorials/150440-turn-off-hardware-accelerated-gpu-scheduling-windows-10-a.html
2. If there is Dual HDMI Graphics Card, please try to change to another one to have a test;
3. Could you please help me check the system info on the computer: https://www.tp-link.com/support/faq/2722/

Thanks a lot.

@Brook Thanks for the support.

1. Yes the live preview in the VLC player is always the same
2. Model number of the home router: U-COM AYDBB VV2220 Hardware Version VV2220v2, Firmware Version: E_9.5.4
3. I tested the live stream on the same computer with the iSpy program (that was the second screen shot)
4. I switched off hardware acceleration in VLC which removes the green color, but it is still pixeled.
5. Check system info --> I do not have any tp-link network adapters but system info can be seen below (unfortunately it's in German)
6. There is no Dual HDMI graphics card
7. I will try the network stream on a different computer shortly

@Brook I tried it with another PC
