So having had this monitor since June, my advice to anyone considering buying it, is don't.
I got my GP950 in the first batch that OC received and initially was very happy with it; looked great and worked great, but that unfortunately didn't last and the service regarding my problems has been poor.
The issues
After a few weeks the monitor started developing two issues:
1. During gaming, the screen would intermittently go completely black for a few seconds, before coming back on and the 'HDR' notification would appear in the top right. Sometimes this would happen once a night, sometimes it would happen every 3 minutes for an hour.
2. The second issue was even more alarming; the left hand side of the panel, in certain areas during gaming, would for a few frames show a white fuzzy section - this would occur fairly often and over time, appeared to be getting worse.
I understand my opinion is somewhat skewed by what is effectively bad luck getting a defective unit, but I could have accepted that had the response to resolving the issue been better. My warning not to buy this stems more from the fact you might get a defective unit and be in a position whereby you have to deal with OC and LG's customer service and woe be you at that point, should that misfortune befall you...
There certainly are issues with the screen having some sort of splitting.
I also get a kind of 'tear' in the screen when i cold boot the screen sometimes.
I am getting ZERO help from LG with my issues at the moment, I've contacted them via mail as well as DM on twitter and they're now taking weeks to respond to anything to me, even after chasing them up. They're basically ghosting me and clearly the monitor has faults.
I'm half tempted to try and speak to tech media about this, because its just an ****** joke at this point.
