From HDTVtest.uk ..... 47 ms lag on st60 ... Rub it on your chest ...
There had to be some bad news, right? Here it is: although gaming is still enjoyable on the ST60, its input lag is higher than the outgoing ST50. The fastest configuration is to enable the “Game Mode” and make sure that “1080p Pixel Direct” is disabled. Under this configuration – which is the fastest we could squeeze out of the ST60 – we clocked the TXP42ST60B in as lagging by anywhere between 47ms and 62ms, using the high-speed camera measurement method. Enlisting the more concrete services of the Leo Bodnar Lag Tester, the measurement came out as 74.5ms (it also clocks our old ST50 in at about 47ms, the large discrepancy between this result and our camera method being something we have some theories about, but are still investigating).
As you can see, measuring input lag is not always an exact process, so to get a better understanding, we played some first-person shooter (FPS) games through an HDMI splitter, simultaneously feeding our old 50ST50 as well as the new P42ST60 (by the way, we checked to the best of our ability to guarantee that the HDMI splitter wasn’t adding its own lag, and didn’t feel that it was adding any). The take-home message should be this: this year’s ST is definitely slower for gamers, although exactly how much is difficult to determine.
We tried everything we could to reduce the TX-P42ST60′s lag, including cycling through picture modes, enabling/disabling “1080p Pixel Direct”, changing the “HDMI Content Type” mode… but 47ms was the lowest number we could get. This by no means makes games unplayable, but the buttery-smooth, blink and you’ll miss it responsiveness of the ST50 is not here. We just hope that the step-up series – the GT60, VT60/VT65, and ZT60/ZT65 – can improve on this… although it’d be the first time a higher-end model was had less lag than the mid-ranger so we’re not hugely hopeful. Still, those higher-up models do feature the new Hexa-Core processor… so perhaps the ST60′s slightly decreased gaming responsiveness will be a one-off.
