So I'm not sure how many people care about this, but it was something I really wanted to see when I was researching PDP's. I looked for hard numbers for quite a while, but for the most part, couldn't really find any and just had to go by anecdotal reports or one line blurbs from reviews (usually for foreign equivalent models that may or may not be the same). The goal is for this thread to be a one-stop compilation of several displays, so please post results or PM me links to others tests so I can add them.
You can read more about the testing procedure here
and even try it yourself
has put together a guide to understanding the general problem of "input lag". Frito
also runs an LCD equivalent thread in the LCD forum that goes into a lot of detail on the subject.*Testing Procedure Instructions*Physical Connections
1) Connect a laptop to your TV and cycle to the video input you used. HDMI is preferred, though VGA is better than nothing.
2) Do not run your tests through an Audio Receiver (AVR), use a direct connection between the TV and PC. This is very important. Some AVR's can and will introduce lag, even on 1080p "Through" connections. OSD overlays are the biggest offenders.On your PC
1) Turn off Windows Aero (see how here
). This is very important, Aero and V-sync will skew your results.
2) If you have a dedicated video card (Nvidia/ATI), it may be helpful to disable (force off) Vertical Sync. I believe disabling Aero usually takes care of this, but if you have doubts, this may be worthwhile.
3) Right click your desktop and choose "Screen Resolution". (*Note* these are Windows 7 instructions, Vista/XP may differ slightly)
4) Click the "Multiple Displays" drop down and select the "Duplicate these displays" option.
5) Your desktop should now be mirrored/cloned to your TV and laptop display simultaneously.
6) Point your browser to this link.On your TV
1) Use the display's "Game Mode" (check the manual for instructions)
2) Turn OFF
all special processing features in the TV's menu (e.g. CATS, Motion Smoother, Dynamic Contrast, Frame Interpolation, Cinesmooth, Blur Reduction, Local Contrast Enhancer, etc...)On your camera
1) You will want to use a mode or option with a fast shutter speed so the timer numbers show up clearly.
2) On lower quality cameras, using the flash often helps with this.
3) Start the timer in your browser and take a picture so the numbers are visible on both displays simultaneously (see below for examples).2013 ModelsPanasonic S60, 34.1ms (by David Katzmaier via Lag Tester)

Panasonic U54, ~20ms* (by myself) *vs. unknown laptop LCD, additional results in post.
Panasonic GT30: ~24ms* (by Chudsmith) *Average out of 43 shots. Point of comparison is unknown LCD.
Panasonic ST30: ~15-32ms* (By thepoohcontinum) *Primary result was 32ms. See his post for measurements of frame interpolation and other processing features, 62-125ms (also tested by Gandu)
Panasonic S30: ~16-32ms* (By DrFrank) *Point of comparison is unknown laptop LCD. Windows Aero on, results potentially slightly skewed.
Samsung D7000: ~34ms* (by Varkeast) *Game Mode (also tested by notext)
Samsung D550: ~20ms PC Mode, ~32-50ms Game Mode* (by badmeng and DrFrank) *Point of comparison is unknown laptop LCD. Windows Aero on in DrFrank's testing, results potentially skewed.
LG PZ550: ~100-117ms* (By DrFrank) *Point of comparison is unknown laptop LCD. Windows Aero on, results potentially slightly skewed.
Panasonic VT25: ~15ms* (by Jrod0802) *Note this is a VGA test, HDMI could yield different results. Point of comparison is also an unknown laptop LCD panel.
Panasonic VT20: ~32ms* (by mechashiva2k) *Note test source is unknown laptop panel.
Panasonic GT25: ~15ms* (by toolman02) *Note test source is unknown laptop panel. (Also tested by Zodduska)
Panasonic G25: 16-32ms* (by NOAMattd) *Primary result seemed to be 32ms.
Panasonic S20E: 18-30ms* (by AABBCCAA) *Note this is the nearest European equivalent of the North American S2, there could be differences between territories.
Panasonic U2: 28-43ms* (by Drapers) *Shutter speed makes it difficult to call. Also note test source is an unknown laptop LCD panel, his supplementary tests suggest adding at least a full frame (16ms) to the values.
Panasonic C2: 30-50ms* (by Nerv_001) *Shutter speed seems too slow to call it definitively. Also note test source is an unknown LCD panel so actual lag is likely higher.
LG PX950N: ~50ms* (by Graco) *Note this does not include lag from the LCD panel tested against. It is also the Scandinavian model, could be territorial differences.
LG PK550: ~86ms* (by shaddix) *VGA, presumably a "PC Mode", measured ~46ms. HDMI labeled PC does NOT seem to reduce lag.
Panasonic G15: ~20ms (by Mr. Deap*) *480i measures included in his post.
Panasonic G10: ~15ms* (by myself and re-tested) *Note my laptop seems to lag 4-7ms based on comparisons to Deap's CRT findings, so it should actually be ~20ms as well.
Panasonic S1: ~30ms* (by myself) *This could be a difference b/t the S1 and G10 in general, or the sizes classes (e.g. 50" Vs. 65"). See my comments in link.
Panasonic X1: ~35ms (by Frito)
Samsung B650 PDP (by cleh19)
Standard Mode: 80-110ms
Game Mode: 30-50ms
Pioneer Kuro 5020: ~45ms* (by Video313) *Mode is unknown, but this seems to line up with other comments I have seen with Game Mode and Game Pref on.
Samsung A650 PDP: 60-80ms (by tqn)
Pioneer Kuro 5010: ~60ms* (by tqn) *Mode is unknown
Pioneer Kuro 5080: ~20ms* (by Mathesar) *PC mode tested. Possible normal or game modes could yield different results.
