It's interesting to consider that one of the top performing TV on this list is also a plasma TV ( Panasonic TH-58PE75U) and meanwhile this one is near the bottom.Confirm Common model prefixes are SA-, SC-, RR-, RZ. This combines both input lag and response time, and is closer to what you would actually experience in a game. full response is a more realistic measure of lag, and requires the display to reach 80% of full brightness. This overly optimistic value doesn't tell how long it takes to see anything useful, but matches what other reviewers call input lag. 1st response measures how long it takes for the TV to start responding (I use a 5% change in display brightness). To give an example, input lag for 720p varies between 78 and 93ms each time your turn on the set (or change inputs).īecause lag varies over time, I've elected to report the average lag values here, since that seems fairest, but there's no right answer for more discussion of this issue see the above link. Complicating things significantly, this TV is yet another display that does not actually sync to the input signal - instead it fills its own internal frame buffer from the video input and then draws that with an arbitrary extra delay. I measure at the top and bottom of the screen, but as it turns out these produce the same results: the entire frame updates at the nearly same moment, top to bottom. This device sends a frame of video over HDMI and measures how long it takes to display it. I used a piLagTesterPRO to measure input lag. In fact I toggled all quality settings and none changed the lag. But it does not change the lag any, so I guess it's just for marketing (maybe it changes the color balance or something).
