Review Summary

Rated 4 out of 5

Gorgeous Image, only one flaw

The monitor has a great picture on it. Much like the previous model 39GS95QE-B.AUS. WebOS is ok for my first time ever using it. Although WebOS has more features and functionality, I think the settings in the previous model were easier to use and find. My biggest issue is I cannot get the monitor to go in standby mode and do a pixel clean on its own. Contacting LG was no real help as they initially told me it didnt have a standby mode. I had to take images and show the guy it did. Every time it has inactivity, it says no input, attempts to go in standby and then comes back out and starts the no input again. This is the same across three systems. I even tried to turn off the network on the monitor and unplug the current selected input to see if that would help. It did not. I had no issues with the previous model going in standby and cleaning itself. Hopefully they get this fixed soon.
