deepflame If you mess around on the Blur Busters forum there is a lot of talk about the 240HZ having issues running 60hz content. They are first generation 240hz panels and a lot of people had complaints with them. From what I understand about this particular monitor I bought it's considered a mature 144hz panel and it's new and exclusive to this monitor. A lot of monitors use the same panels in different monitors. So when I put the overdrive feature to max I have no issues. I don't run a blue light filter or anything. This tells me that my main problem is motion blur. I believe everyone on this site needs to consider that to some degree. It's a problem that plagues every CCFL and LED 16MS persistence motion blur on every 60hz LED. This never existed on Plasma and CRT. It creates a problem called eye tracking where you eye believes the image is going to be in a certain spot when the screen refreshes but it's not. Rtings.com explains this good in there Youtube videos. They have a five part series explaining lots of LED problems.

I have suffered from every 99.9 % of every screen I have ever used for 11 - 12 years and every LED light until this. The two OLED screens that didn't affect me The Samsung S2 and my Yotaphone 2 I was told by the head guy at Blur Busters they use crappy LED's to. 80CRI so it really got me thinking that can't be my problem. I bought probably 10 monitors and returned them in the past 3 months till this one. I think I'm on 1 month and half with it now I have had every game system I own hooked up to it and use it on the computer and have no issues. I brought it on vacation with me and was gaming on it as well. I can use the screen unlimited and I have had tons of 8 hour gaming sessions on it. Over drive is a complicated function and most monitors have terrible over drive features. The Blur Busters guy said that a good over drive can make a monitor amazing. It's predicating where the pixels need to be before they would normally get there and what color they need to be if I understand it correctly. This is a big deal when you think about how slow an LED screen is. Most people think when they stare at a screen it's a still image but no it's a screen constantly redrawing itself and LED does a terrible job at this. especially when you see the Rtings youtube videos. https://www.youtube.com/watch?v=3BJU2drrtCM Check that video out as well by the Slow Mo guys to see how different screens work in slow Mo. That LG monitor you bought I thought there was a giant thread on it on Blur Busters and it wasn't considered very good. I could be totally wrong on that. I'm also testing my first LED light bulb but I want to wait a bit before I say anything. I believe it's only a CRI 80 - 85 but flicker free. Early Impressions is it's not giving me any problems but will see. I know that CRI isn't an issue for me it mainly has to do with motion blur or the lack of phoshor on the blue spectrum or the digital nature of LED. The Blur Busters guy told me that CRT is way easier on the eyes then LED. You have to have a high refresh rate and BFI sometimes to get that smooth clarity of CRT. Also he said panel type matters for different people I think my panel of choice is TN but that may not be the case for other people.
