Just got my G751JT-T7019H from amazon uk. here I will post all the issues i have found and try to find solutions for them.

1. Slight backlight bleeding in pure white background.
not visible in pure black background.

2.Screen has a slight red tint.
Temporarily acquired acceptable color accuracy after adjust gamma settings.

3. USB port problem.
problem fixed. not laptop fault. turns out to be BIOS misconfiguration.
