This product is horrible even if the quality picture is good, first you have 1/3 chance to get this monitor without dead/stuck pixels and secondly, the 1009.3 firmware (that fixed flickering issue) has another problem : "Scanlines" : horizontal lines appear on the entire screen .
To be able to reproduce this problem, use Odyssey G7 32" firmware 1009.3, connected on Displayport 1.4 (240 Hz) with a NVIDIA graphics card / (or AMD ?) + Black Equalizer set on 13 (the default value that engineers are not scared to put this unlucky number...) : 1) You can reproduce "Scanlines" issue on these following sites (on a browser like GOOGLE CHROME/ MICROSOFT EDGE and MAXIMIZE the window) :
Me and my friend whom bought this near end of last year also get these scanlines (and the coil whine when it happens) from those sites and some games.
I noticed this the time i bought it but after few tweaks in black equalizer and brightness it was ok on the games i was playing...at the time... or that i didn't noticed them enough. But recently i started playing Wolfenstein 2,(and new powerful gpu am able to ramp up the graphics) due to alot of lighting in that game i noticed the scanlines far much more and ruining the game. And now am seeing more on other games .. more rarely but at the right angles and lighting... it's abit offputting.
I been looking around trying to find a fix but seemly there is none 😞 so please samsung.. find a fix as it is the only thing makeing this a great monitor.
