The New Definitive HDTV Lag FAQ

I can’t say I’ve done extensive research but I thought Panasonic sets would be above the A650, on account of the LZ800 at least.

Also beyond the LH30 and LH20, the other LG series I’ve seen tested don’t fair as well.

I hear good things about Sharp but there seems to be a lack of tests on them that I could turn up when trying to pick my set.

Well after months of research I’ve finally decided to go with a LG 32LH20 for my gaming needs. My parents and girlfriend agreed to get me one for Christmas. Thanks to shin shoryuken and a couple others in this thread for the info on the tv, I would have never found out about it otherwise.

@ shinshoryuken, is could you do a test on Tekken 6 to see if there is any different between the two versions?

just all in my opinion…maybe it should be

most new LCD sets with fancy image enchantment < Sony < Newer Samsung < Toshiba < (Panasonic & Samsung a650)< (Sharp & LG)

there are a few other LGs that perform just as well as the LH20 but are discontinued

My 360 got RROD …so I have to get it repaired, then I’ll do more testing.

thats same as ASUS VW246H Black 24" correct? I am trying to get one too but newegg dont carry the 23" anymore(discontinued)

well they have component to HD cables/adaptors but I never used one so cant tell you if there is any added lag. BIP is probably the one you want.

I ordered mine here.

I sold my previous LCD TV and picked up a 40" Sharp Aquos which was on sale for this week. The first thing I did was pop in RB2 (360 hooked up via component) and go straight to the lag calibration. The camera on the guitar couldn’t detect the screen or the speakers no matter how I held it, so I manually adjusted it. No matter what mode I had the TV set to (standard, dynamic, movie, game, ect…) the results were always the same: about 33ms for audio and 77ms for video. That is worse than my previous TV. So, I turned the lag on both down to zero, put the TV in standard mode, went to practice mode and full combo’d the “Pleasure (Pleasure)” solo.

After playing some more difficult songs on different settings I can tell that there is some lag, but not the numbers that I got with the calibration test. Game mode does fix it, but just a little, and even then it didn’t need to be fixed all that much to begin with.

Sorry that I cannot give some accurate testing methods to this thread, but just advice for people who are using the Rock Band 2 test as a basis: it’s not a good one. Without the stopwatch test, playing it is the only way to know for sure.

Thanks for the immediate feedback but I feel like even though the LG 47H30 is a good LCD for gaming, do movies and sports look like crap on it cause it doesn’t have a good image processor?

Is there a middle ground? Like an LCD that is manageable in game mode and when it isn’t in game mode looks good for movies.

Thanks,
Chris

The LH40 series?

Hey guys, made a 60 fps video of the vw266h. Anyone have a tutorial on how to divide the video into individual frames to determine input lag? Or I can send it to some knowledgeable input lag guru here to determine it as well.

Short answer: Just press pause.

Long answer: I suspect your testing methodology may be flawed. You need a control to compare the vw266h to. i.e. a CRT monitor. You should simultaneously output to the vw226h and your control at the same time, film it, and then review the video. You should also confirm that your captured video is in fact playing at 60fps.

Ignore the post below you…another one that didn’t read the tread.

anyways…

if you have a 60fps capable camera, the basic idea is this

Use virtualdub to view the video frame by frame.

here’s an example I did

I actually like the idea of using a CRT as a control. That way you can identify if there’s something throwing off the test results.

So what do you suggest then?

What test have you done?

He was basically saying to use the LCD vs. CRT stop watch test.

If using a CRT as a control, what makes you think that other factors won’t throw off the test results?

like the video card for example? how do you know if the video card port are sync?..etc…

read deeper through the tread, I gave alot of reason why in my opinion that the LCD vs CRT stopwatch test ain’t that accurate.

anyone know what they used for gods garden tournament?

Well, based on what I did, I used both Ryu’s LK and LP.

Ryu’s LK had 6 frames of inherent lag.
Ryu’s LP had 5 frames of inherent lag.

Not sure how you get ms calculations from that but based on my vid, those results seem about right. Can give the vid to anyone who wants it so they can see for themselves.

it looks like you did your test on a CRT so I guess the VW266H only has 1 frame of input lag which is pretty much the acceptable standard, right?

I would like to see the video.

did it take you 5 frames after the input to see the first start up frame for the far standing jab?

Even if I concede that it is possible that one display port may lag more than the other, you should still perform the experiment with a CRT as control. Then you can potentially eliminate problems with the methodology or with the other variables e.g. is the camera actually recording at 60fps? Is the controller you are using causing lag? Is one display port lagging more than the other? etc.

Your method without a control only can verify whether there is lag introduced from the button press to the action appearing on the screen or not. It cannot verify the quantity of lag caused by the display. e.g. using your methodology may reveal 6 frames of lag from button press to display. How much of the 6 frames is caused by the display and how much is caused by the other variables? You can answer that question by using a control.

Here’s the vid. I was recording at 60 fps on my gf’s digital camera. 320x240 resolution. I could tell it was 60 fps because we normally record at 30 FPS and just moving the camera around it was extremely smooth with it’s framerate.

Yes, it took 5 frames to begin to see the start up frames of ryu’s jab, and 6 frames for ryu’s short.

oh wow I love craigslist lol. just picked up the asus 24" for $100. this is mint condition and the dude said he used it 3 times then bought a huge tv for movies and dont need this anymore.

gonna play some sf later on and post PERSONAL opinion…

What you’re saying to do is two completely different tests in one, which is honestly too much to ask of people. At least this testing method has more predictable variables. All we need to know are
-controller used (should be obvious)
-console
-resolution
-monitor

The rest is fairly easy and the test is to repeat for verification. The rest can be checked if the video is uploaded online (like proper frame rate).

I’m not saying you’re necessarily wrong, but straight telling people their efforts aren’t good enough when they are actually putting in effort. My only personal stipulation with the above test is that people do it more than once to check that their results are consistant.
