I was looking for a decent IPS 4K monitor with G-sync. Unfortunately there weren’t a lot of options out there, but this monitor hit all the marks. The monitor was in almost perfect condition except for a minor scuff on the stand, otherwise no other issues and no dead pixels. The colours look amazing and there is no major backlight bleed either.
