So far really enjoying the LG 27GN950.
Super clean image with this IPS panel just not great contrast.
Kind of cool has an RGB light on the back that can be set to any color for ambient lighting or change colors and move in different patterns.
Can set it to react to sounds display on screen which is kind of cool in games especially World of Tanks firing the tank looks like a mini explosion behind the screen and in Rocket League when you score it does a little celebration of lights depending what color team you are on.
Can also set it to match the colors on screen just to add a little immersion which is the one I mainly use but only about 50% brightness.
Have it running on the pc 4k 144hz and it works perfectly with the Xbox current 1440p 120hz update.
Here is the lighting and it does have a fan but its very quiet.
