Ummm......
Input lag and Response Time are not the same thing. Response time (pixel ghosting) has nothing to do with input lag. Please for the love of God READ THIS:

This a common misconception. You see, TV/Monitor manufacturers refer to "Ghosting" as "Response Time" (ie; the amount of time it takes a pixel to respond). They will never, I repeat NEVER tell you how much their TV lags (ie; the amount of time it takes for mario to jump after you press the A button). In fact, they don't even have a clue as to how much their TV's lag, none whatsoever because 1. They don't give a crap and 2. They don't test them and 3. They consider gamers a minority and market TV's towards movie lovers.
To further solidify things, a specific TV can have 200ms of Input Lag, and 8ms Response Time. Please read the following post of mine for more info -
http://gbatemp.net/threads/retroarch-a-new-multi-system-emulator.333126/page-91#post-4543884 - read the second half entitled "P.S." and while your at it, check out my other posts on the same exact page for more detailed info concerning why Digital display's will always lag and why Analog (CRT's) will never lag (interestingly enough, CRT's have never EVER had input lag OR ghosting, and always have had perfection in both areas. How can it be that old technology destroys modern tech when it comes to these things? Hahaha......)
And one more thing, there is absolutely, positively no device whatsoever that can eliminate Input Lag, which is determined by the TV and not an outside source. AND there is no device that can eliminate ghosting (ie; reduce response time) ether. EVERY SINGLE LCD TV ON THE MARKET has ghosting. This is a fact, period. The amount of ghosting will be determined by the panel and digital post-processing used (remember, processing creates less ghosting and MORE lag......ie; the more processing the more lag). And I've seen the SLG3000 in many videos and again, current displays do not have a high enough contrast or DPI to give you a convincing CRT emulation no matter how great the scanline shader (it will always appear too dim with current modern contrast ratios). Plasma gets close, but LCD doesn't have a prayer. OLED might be the ticket. Still though, even 4k resolution might not be high enough for a near perfect CRT emulation. These new technology's are just not mature enough to give you a substitute for a cheap $10 CRT from Goodwill.
