I bought the M501d-A2R 50" earlier this week. It did a firmware update while I was out of the house and I received v188.8.131.524_125.
I'm attempting to hook up my PC to play videogames on the TV, but I get horrible input lag. Reviews I've seen say that gaming from a console such as the PS4 or Xbox One yield no input lag if you put the TV in "game mode". This setting does not appear in my TV settings as anything more than a preset to turn off all post-processing effects under the Picture settings. Even when I have these settings in place, there is very bad input lag coming from the PC.
Something worth noting: when I reduced the resolution to 800x600 instead of 1920x1080, the input lag was greatly reduced. This leads me to think the issue is related to the GPU's processing power. Would this be correct? If so, would buying a graphics card, say, twice as powerful yield better results?
Can anyone offer some advice or insight as to why this is? My PC is a fairly modern, powerful gaming desktop, yet the input lag when connected to the TV is very bad.
