This is a wrong test. There is a vertical line on the right side of the second test of the grey 18%

I don't see it? Maybe your screen is broken

[@jhon4744]

It is not broken. I have tested it on other screens to. It is verry difficult to notice in small screen but in a big screen it is clearly visible. @@torusx8564

Do we need to download this

[@ColoradoRMN]

No; you can stream it. Just make sure your you tube settings quality is set to 4K / 2160p to get the best sharpness of the video. Play it in full screen mode.
