Sub 1 frame HDTV/Monitor Input Lag Database

Apparently prad.de has a much better way of testing input latency now, using oscilliscopes.

Also, this is supposedly a much more accurate test when doing the current methods of testing

hello, about this hdtv Sony 32W400 - 8.6ms input lag 32" 1080p are you sure about the name? i can find just 3W4000

I got a LG 50PZ550 plasma and it has a noticable bit of input lag. I notice on the list on the op that the only LG has a rather large input lag, would that be the same across all or most of their models?

Not necessarily. On of their lcds was sought after back when I was looking for a gaming TV.

I see. Is there a sight that lists these for american models as well?

Does anyone have any info on the ASUS VH238H? It’s only $10 more than the VH236H.

IT seems the LED backlight is the only diffrence. There are some unsubstantiated claims that the LED one has more input lag. The majority of what I’ve seen, though, indicates that they are the same aside from the light. Google “ASUS VH238H input lag” to find the various discussions out there, for it.

Sony has annonced 3D tv special for Ps3. I just hope they put some efforts and make it also lagfree…

Since you are on topic about the vh236h monitors. Do you know if the video mode makes any difference in terms of input lag? (game, scenery, theater etc. etc)

Various posts says it doesn’t not while other says there’s a difference.

I have no idea, unfortunately.

Did anyone catch which NEC monitors were used at the Dromstruction tournament? The commentators on Finest KO mentioned that they were using them.

[Ragnorok64]

I’m not really sure how to find out the model of monitor. Hopefully one the the tourney organizers take note of it. In any case if they are comercial monitor for use in hospitals, I’d imagine that they are probably pretty expensive.

[Ragnorok64]

I asked in the Dromstruction thread according to jinxmitchell the monitors used were the NEC V421-2.

Keep in mind the following things:

1. Tests using clone mode on a PC or laptop are invalid, they may not refresh each display at the exact same time, and that can give innacurate results. Best to use a VGA splitter. Also using that, it makes older CRTs work (dunno why but the CRT gets fooled into thinking it’s in 1280x1024 mode with cut off pixels)

2. You need a large sample size. The numbers shown aren’t final, those are just averages of however many pics they’ve taken. A sample size of at least 30 or more pictures is better. When taking pics you don’t get like say a 7.8ms difference on the clock, its either 0 frames, 1 frame (~16ms) or 2 frames (~32ms). Those are just averaged out.

3. Camera shutter speed. A slow camera shutter speed makes the test results harder to read, as well as allow the display to make a transition if it hasn’t yet. Use the quickest shutter speed possible on your camera. I think ghosting caused by the panel’s response time may impact numbers shown as well.

Thanx for the suggestion I appreciate this, but regarding 2 & 3 couldn’t you instead record with a camcorder or any recording device upload on youtube so the user can hit the pause button to see the time difference?

[threi]

Well even if you had a good camcorder that could record at 60FPS that still restricts you to only 16ms of accuracy, and for testing input lag you obviously need more than that (i.e. cameras with really short shutter times). Also do they even have 60FPS vids on youtube yet? I assume they would re-encode it to 30fps anyways.

In my tests with a VH246H I saw no difference.

Youtube used to “support” it. You could bypass it by uploading a 60 FPS FLV but it’s not an accepted file type anymore.

If you watch this in 240p you can see it’s 60 FPS.

I’ve been using a 40" tv as my PC monitor for the last couple of years. It’s been starting to go a little crazy recently. I’m considering replacing it with 2-3 EVO monitors. You know this totally sucks though I paid way to much for that thing for it to be acting up now. CRTs will last for well over a decade but are LCDs supposed to crap out in a few years?

As old as it makes me sound, they don’t make anything like they used to.

I just found this chart in a new Anandtech review so here’s a few monitors to add to the list
