My laptop shows streams and videos only black and white. Can someone help me there?

It's black and white on YouTube videos but sometimes you can see color. I use geforce now, which is the same. Games are displayed in black and white. Can anyone help me with that?

First, try another browser to narrow down the source of the error. Are the videos in your media player also SW?

Yes, there are also sw

Then this is due to the installed codecs. Do you have any codec pack on your system (is it Windows?)

Yeah i use win10

Spontaneously typed, MP4 videos are not decoded correctly. If an additional codec pack is installed, throw it down. If not, you can test for example. Install the K-Lite codec pack. I do not know how well you are with the topic…

I'll try.

No did not work
