The New Definitive HDTV Lag FAQ

I bought a panasonic l32u3 and tested it against a dell laptop via hdmi (Aero disabled, @720p). (0-)10-20 ms difference. Of 20 pictures shot at 1600iso 1/160th six were at 20ms, two at 10ms and the rest displayed the same number. I know this is not the best way to do this test as the laptops monitor probably lags, but I was mainly comparing it to other monitors/tv’s. Earlier in the week, I bought the l32u22 (despite terrible reviews) and of 20 pics, (same parameters) 30-50 ms, most on the bad end. horrible. my 2008 vizio v0320e is slightly better (20-40ms, usually 20-30) Camera: Panasonic L1K 14-50 2.8-3.5 Leica. pictures are huge (forgot to turn quality down!) so I may resize em to post or just run the tests again. If I can repo my crt from the person I lent it to, I’ll try some more legit tests.

note, i spent about 20 minutes on each monitor (and two more) finding the lowest lag hdmi settings. Theres no telling how much the laptop’s monitor is lagging, unless I test that vs. a crt. my Acer h203h is ahead of this laptops monitor (ever so slightly, numbers displaying solid on acer, still changing on laptop, consistently )

custom cab, so I really wanted a 32"… If I can’t deal with the lag, I can always go with dual vh-236h’s

LJAFX - mind uploading photos to a website and cleaning up your post so it’s less TLDR and more readable?
I still barely understand what you’re trying to say. Have you thought of picking up an HDMI/DVI/VGA splitter? you have quite a few screens worth testing and that would remove your laptop’s monitor lag from the question if you had a VH236H. CRT would be best, obviously.
Thanks for posting your results anyhow; making it more user-friendly would be appreciated.

Revelations this weekend used the Acer H233H, just as a reference to put in this thread.

Which one in the pic is that Panny? Since you mention that the Panny has the “lower time” does that mean it is the one in front? If so, you’re interpreting the results backward. The display with the lower (older) time means it is lagging behind.

Any chance you can do it through DVI? I’ve read that using hdmi splitters can also effect the results. Thanks for putting in the time though :slight_smile:

I took the pictures on a 7.5mp DSLR at full size! I will try to resize the pics if I have the time. very large files. @ 15-20 pictures each, It may be quicker for me to re-shoot the u3, v0320e, acer h203h, and resize the l32u22 pics (returned for the u3).

I was hooking up lcd’s via hdmi and comparing the displayed flatpanels.dk timecode.

Dell Laptop, Dual clone, Windows Aero disabled, 1280x720 @60hz (one at a time vs. laptop monitor) hooked up with a hdmi cable.

Pictures were shot @ 1600iso (simulated film sensitivity) with a shutter speed of 1/160th of a second.

Panasonic L32U3: Game mode on, all processing off
6 pictures displayed a 20 ms difference
2 pictures displayed a 10 ms difference
12 pictures displayed 0ms difference

Panasonic L32U22: Game mode on, all processing off
5 pictures displayed a 50ms difference
3 pictures displayed a 40ms difference
7 pictures displayed a 30ms difference

Vizio V0320E: can’t find the pictures! they were between 20-40 ms difference
Acer h203h: no difference/Inconclusive, too close to the laptop’s times to read a difference (but it’s slightly faster/earlier) I also tested vga and it seems to be the same

Please keep in mind, the reason I ran these tests was to find a 32" tv for my custom candy cab, not to show what the actual input lag times are online. I don’t advise anyone to rely on these numbers as they are not accurate(inherent laptop monitor lag) or done to the “standard” (1080, vs. a crt) expected on the interwebs. This test works for me, because my main comparison (from a gameplay standpoint) is the acer h203h 20" TN panel. From a feel standpoint, the l32u3 feels good that’s all I can say. I made a monoprice order last week and they’re still out of the passive hdmi splitter. I’ll probably pick one up next time I order monoprice stuff.

*pro-tip- The Panasonic L32U3 has big time overscan in 720p (hooked up to my PS3) It’s the only set I have ever had to adjust in game picture settings to fit everything on screen. I think I lost an inch around the borders compared to the vizio V0320e that it replaced. This is my main gripe with the U3. Picture quality is great, but most of all, this screens blacks are amazing. Plasma-esque.

I also have a 2008 samsung ln22a330 (22" 720p) that i’ll someday test.

Panny L32U3 looks good from these preliminary results. That post looks much better than what you had before, thanks.
Looking forward to more tests.

How much of a difference do these input delays make? I currently play on a 42" plasma and recently did a calibration test, got a 45ms video delay. Wasn’t surprised considering that it’s a fairly large HDTV. If I were to get a lagless monitor, say the Evo monitors, how much of a difference will it make?

The L32U3 is the one in the front. Thank you for the correction, I don’t know what I was thinking.

I was just thinking that the Panasonic l32c3 could have less of an overscan issue with 720p. it’s native resolution is 1366x768 which is nearer to 720p, so you’re still upscaling. I suspect you may loose less real estate, but still get the IPS Alpha that has returned to this line. Panasonics specs say that the 09 models (l32c1,x1) had ips alphas, 2010 says “IPS Panel” (c2 u2 x2), and “IPS Alpha” again in 2011. I took macro shots of the panels looking for the chevron pattern… looks like it but I need to find my old slr lenses to get a clear/bright enough shot.

Anymore info on these panels? Why don’t they use them anymore??

45ms is massive. It’s almost 3 frames. Think about Boxer’s 3-frame jab and a shoryuken having 3 frames of invincibility - very very noticeable, I’d be willing to say regardless of level of play.

50 ms seems high :frowning:

I was thinking about this set for a PC/console for the guaranteed IPS panel but I’ve heard it doesn’t display fonts well.

Can I run the timer test from a laptop to a monitor? Or does the laptop screen also has inherent lag?

I have no clue as to why they dont use these monitors anymore. i dont have any equipment to test this monitor out but in one of the earlier posts in this thread someone mentioned that ksk picked these out himself for the gods garden tournament. also this monitor has been discontinued for about a year

If I can still get one do you think it’s worth while? Also anyone know what they use now?

if you can get one for a good price then by all means jump on it. these monitors were a regular 450$ i believe but you can get them 100$ or more cheaper if you look around on the web. and i saw some one post this a while back but i cant think of the thread but anyway they use a monitor that i think is only made and sold in japan that supposed to have .5 frame lag when in game mode. here it is The New Definitive HDTV Lag FAQ

So I just got the asus vh236h. I’m playing on ps3 via hdmi. Do I need to change the settings at all on either the monitor or the ps3?

Yes, the screen has inherent lag. Unless it’s somehow a lagless laptop screen.

No. It’s plug and play out of the box iirc.

Hi, This might not be a technical question but I need some advice. I plan on getting a new HDTV or Monitor for my lonesome gaming needs. Of Course, I want something w/ little to No Lag. From what I know an HDTV w/ High Hz has lesser Lag… My question is what would be better for gaming especially fighting games, A HDTV w/ 120Hz or A PC Monitor w/ 1ms response time. In this case I saw a 32" LG LED-LCD w/ 120Hz(2.4ms) & 27" ViewSonic LED-LCD Monitor w/ 1ms response time. Which would be better?

Many Thanks.

“To reduce blurring, most 120Hz LCD displays use a system called MEMC (motion estimation and motion compensation) to slip in a new frame between each of the original frames. The end result is one extra frame for every true frame.”[LEFT][SIZE=16px]

[LEFT][SIZE=16px]in a nutshell: nope. a monitor/HDTV that has atleast 1frame input delay(anything higher than that and it’s too laggy) is preferable.[/LEFT][/SIZE]
