The New Definitive HDTV Lag FAQ

ASUS VW236H / VW246H / VW266H / W’H’ (series -> Has anyone tested the lag on the larger screens? Surely this is of importance :slight_smile:

I want to buy ASAP, but just need to confirm these points. Ideally, if the lag is equal id get the 26" bad boy

thanks all, appreciated

I have the vw266h but still unsure how to perform lag test on it. A lot of people say rock band 2 is inaccurate and other tests are inaccurate so i’m just waiting for an accurate way to test it.

I’d just like to throw this out there to anyone considering the 26’ Asus. The panel is a 16:10 panel, not 16:9 as is native for SF4 and all other fighting games. It can do either two things:
-stretch
-1:1

1:1
Gives you the exact resolution as the signal it receives. For PS3 that means 1280 x 720 on a 1920 x 1200 screen, which basically means you have big chunky fat black borders around the image. If you want to get an idea on a HD monitor, try watching a 720p movie without stretching it.

Stretch
The extra 20 pixels will make the characters on screen appear slightly taller. For most people this probably won’t matter, but for some this could make spacing (particularly with jump ins) feel different than normal.

If you have a 360 you can buy this, set your 360 to 1080p and if you don’t care about 10 pixel letterboxing you can be on your merry way. As for PS3 well… because of the funky scaling thats required to change aspect I wouldn’t expect it to be as lag free as the smaller models.

edit: I wish people would at least try the Rock Band 2 auto test. While it is inaccurate, it is also consistantly inaccurate, so it would be interesting to compare results. All of the monitors we use for example score about 9-12ms through the test, with 9ms being what the Evo monitor gets.

Thanks a lot, very useful. Since posting originally I also found out about the 16:10 vs 16:9 - it also seemed that this would require more scaling and hence, potentially a bit of lag.

Ive gone with the 24", for me its 2/3 the price, and i found a good PRAD review (link was on a SRK thread, maybe even this one). where by it had essentially <1ms (0ms) input lag 99/100 attempts, with one 30ms random result.

i have both xbox and ps3, however my TE stick is on the ps3 (SE on xbox) so ps3 is prefered…im a little concerned that the xbox (which can upscale 1080p) will acutally have less lag, as the ps3 will force the monitor to scale 720p up to 1080p

anyhow, thanks again for your response

I wouldn’t be too concerned about PS3 vs 360 lag unless the TV has a really really bad scaler. If that’s the case it’s probably laggy to begin with anyway.

Even in a tournament environment, from what I’ve seen, they tend to use PS3’s as they are easier to make sticks for. Correct me if I’m wrong, but as long as you can average within 32-34 ms of lag (2 frames) you shold be fine.

Thanks for the info. Looks like I’ll have to settle for a 720p tv.

I’m assuming you are all talking about the 32 inch Sammy A650…

other than Samsungs are overpriced, is there any other reason this TV is $1000? :looney:

I have a Vizio VW32LHDTV20A, and if it is anything like the 40A there is an average of 50ms when I play Rock Band 2 on 360 through component at 720p. My TV has no “game mode,” and the lowest I’ve ever been able to get it is to 32ms.

No, you’re wrong. Players expect gameplay to feel the same as it does in arcades and would not be happy with 2 frames of lag. Any requirement for adjustment is not good enough. If tournament organisers haven’t done their research and aren’t on top of things, they should be sticking to CRTs.

Even at top levels. Isn’t 2 frames of lag undetectable? Also the displays in the arcades lag too. Though I don’t think anyone has been able to test the lag on them

Um…where did you get this conclusion?

I know I’ve mention that some HD arcade cabinets does have lag…but I also said that not all of them do.

Where are you getting your source?

My first sentence is a question, not a conclusion.

The second is based on posts (more than likely your included) mentioning lag in arcade cabinets coupled with the fact that I don’t think I’ve seen a single LCD panel in the 32" range that’s been reported as having 0 lag. If I missed that, though, please point me in the right direction.

ok …my bad on the conclusion part.

I know the Vewlix L and the delta 32 lags a bit.

Is it even possible for LCD technology not to lag at arcade display size?

well its possible…

SF4 running on a Vewlix F.

That what the arcade in japan is using for SF4.

the monitor on those are uber:wink:

Do we have any tests on that though?

On the 2 frames thing I believe I originally go that in mind from a couple of posts on AVSforum

The relevant parts being.

and

To corroborate I did find this blog entry from Tony Cannon (GGPO guy) on capcom unity.
http://www.capcom-unity.com/s-kill/blog/2008/08/29/ggpo_networking_guru_talks_sf_hd_remix_

Emphasis mine.

The 2 frames thresh hold keeps popping up and it seems those who can notice less than that are very very rare. So, considering current readily available LCD technology, I’m going to endorse the 0-34ms as acceptable input lag for the time being.

Does the new guitar hero van halen demo on the psn has the input lag test?

um…

I think its all relative.

for example
If a group of friends who only plays on a 2 frame lag screen(lets call them group A) and another group of friends only play on lagless screen(lets call them group B). What if group A decided to play group B using the the 2 frame lag screen?
Who do you think will have the advantage? what if they used the the lagless screens? who will have advantage then?

anyways …not trying to argue…I don’t even know if Im making any sense…It’s late and Im on meds.

which of these monitors i should get: asus vh236h or viewsonic vx2433wm, i want a monitor that will display my games but also blu rays great. which would you suggest for me?

I just wanted to report my experiences with a few 32" 720p LCD TVs if anyone is looking in that market right now. I chose to buy a 720p TV because at 32" I didn’t see much in terms of value for spending the extra money to get a 1080p panel and I wanted to avoid any unnecessary upscaling to 1080p if the game was rendered at 720p. Since I did not do any empirical testing, the following is just my subjective opinion.

First of all, in order for you to have an idea of my standards, I am a Viper player. I cannot tell the difference between playing on a CRT and playing on my computer monitor.

The first TV I used was a Toshiba 32AV502R. No matter what settings I used, the lag was slight, but noticeable and playable with slight adjustment. I would say it felt like a 4 bar connection in online play when I was using a CRT. There was a noticeable delay in change of direction when i walked back and forth. I had to adjust my timing for landing ultra after ex seismo xx sj hk.bk ultra because I found that when I used CRT timing to ultra at head height, the ultra didn’t come out until waist height. I also had to adjust my timing for deep/safe jump in HK. When I used CRT timing to do jump ins, I whiffed them. My friends that were non-viper players (mostly shotos and classic sf2 cast) were unable to detect any difference. I was unable to detect any meaningful difference playing Uncharted 2 on this TV vs. playing on my CRT.

The second TV I used was an LG 32LH20. I am unable to detect any difference between this TV in game mode and my CRT and my computer monitor. I am very satisfied with my purchase of this TV for gaming.

In conclusion, I cannot say that the LG 32LH20 does not lag, but it is definitely LESS laggy than the Toshiba 32AV502R, and the amount it lags is below my ability to detect.

Interestingly, my friend has a 5 year old 32" 720p Toshiba 32HL86 that I also am unable to detect any lag on.
