I've recently bought an LG IPS237L. It has the option Super Saving Energy. When I turn that option on sometimes after the PC boots the quality of the picture is really low. The colors are wrong and it displays big pixels. You can see that on a video I recorded. At the beginning it is wrong then I reconnect the HDMI cable and it repairs. My question is- is that a monitor problem or maybe the video card? Earlier I didn't have similar issues but I had a smaller monitor (with lower resolution) and I used DVI port, not HDMI.
