Hello.
I have purchased a Lenovo Legion R25i-30 and noticed that it gives off red colour on any colour temperature, especially on DCI-P3 and sRGB.

I tried to adjust the colour temperature, reset to factory settings again, сonnect to different DPI and HDMI ports, it doesn't take away the symptoms much, tomorrow I will try to connect to another pc, add info later.
Both monitors (I bought two) of this model had this problem from the start, and reinstalling drivers and installing Lenovo software did not help.
I noticed a certain pattern in the pixel inversion test on the http://www.lagom.nl/lcd-test/inversion.php, it's on the video:
