Nice to see more people into the art of painting with light.
When you stop and think about it Id bet you can sit a million people down in front of two panels, one with a 1ms response and the other with a 6ms response and equal in every other way and no one could tell them apart. Working in the critical power industry there are machines that are made to switch between two synchronized sources, namely a static switch. They are marketed and sold as a seamless non break transfer when in reality there is no such critter. There is always a break transfer of 4-10ms. Sensitive electronics cant tell the difference, you would never know it if you were holding a light bulb in your hand that is powered by it. I have to use the high frequency Oscopes to be able to capture and compare to make sure the switches meet specifications. So if there is a human that can see and react in 1ms please come see me, I have a million $$ job for you as you have abilities that exceed most high frequency electronics. Refresh rate and color reproduction is where its at and even the refresh rate has human limitations. Even pixels per inch have limitations in perception.
On the other end of producing images in the first place the higher resolution cameras lose sharpness when the pixels per inch on a given sensor go past a certain point. Im still sitting on two older camera bodies because of it. I'm a Canon person and the CPS facility in Jamesburg NJ is 10 minutes from me. When new stuff comes out I can get it on a loan to try out. Im still sitting on my 1Ds MkIII for full frame and 1D Mk IV for sports. Until the actual sensors get bigger, like the high $$ Hasselbad large format caameras, jamming more pixels in the same space just kills IQ.
With all that said Im using a PG348Q and very happy with it for color reproduction aand response. Xrite colormunki calibration before and after has nearly no change, that says something.
