VIEWING ANGLES / PICTURE QUALITY
I ended up taking the UltraGear 34GL750-B at home for a more in-depth/thorough test (20 days worth) with games and movies and as you can see both image quality and colors are very good. As for viewing angles things are also good (i was expecting slightly better however) and do take into account that the keyboard LEDs are flashing on the screen so the camera has a hard time with colors and even brightness (i noticed this while i was working on the pictures and well after i had placed the screen back in its box).
Thanks to its 144Hz refresh rate, 5ms response time and G-Sync compatibility i also didn’t notice any screen tearing while playing with the RTX 2080 Super (the not so deep black issue of IPS panels is however somewhat evident in the above picture).
