The New Definitive HDTV Lag FAQ

If you’re playing on a 360 just use the VGA cable. You won’t need the HD Fury at all if you do.

I haven’t had a chance to test mine yet but it seems to knock around 8-16 ms off the lag of most of the people who reported here.

I’m using PS3.

I’ll guess Ill have to test and see. From what im reading the PS3 won’t upscale SF4 to 1080p since Sf4 is 720p. So even if I have the VGA converter the TV would still upscale 720p to 1080p. Xbox on the other hand can do that.

TV: Pioneer Kuro PDP-5020FD
Test: Rock Band 2 (360) auto calibration
Resolutions: 1080p and 720p
Results: ~61ms of lag without ‘game control’ turned on, ~48ms of lag with ‘game control’ turned on

The results surprise me as many people have posted at AVS and other forums that the ‘game control’ setting completely eliminates lag. From what I’m seeing, it drops it from around four frames to around three frames.

I was wondering, how much lag do you get from using a wireless controller? Is it not even 1ms, or is it comparable to the lag you might get on an HDTV?

Basically I’m wondering if HDTV+wired might feel the same as SD CRT+wireless. It would be convenient if switching to my new wired joystick would end up compensating for the lag on whichever HDTV I end up getting!

Toodles has objectively tested the 360 and PS3 standard controllers and was surprised to find they only lag 1-2ms.

I just tested my HDTV with RB2 and found that using the RB2 guitar increases the lag because it’s wireless. I got 49 on audio and -29 on video with the auto-calibrate but when I put my SFIV TE stick in and did the test myself it was 25 audio and 0 video each time.

Sounds like you’re doing the test wrong if you got -29 video…

You shouldn’t need to do anything for the test, no strumming or anything. Just start the test, and put the guitar in front of the TV.

Would the HDBOX PRO do the same thing as the individual vga leads for the 360 and PS3 ?

That what I did, the auto-calibrate with the guitar’s sensor. I ran the test automatically with the guitars sensor and again with a wired SFIV controller. no lag with a wired controller.

Westinghouse 42" with vga input on xbox 360 btw, forgot that detail.

Well a negative lag is impossible, it would mean that your TV is faster than your xbox and it can anticipate the data it has not yet received …

In my opinion either the test is done wrong, the guitar is not correctly set in front of the TV or the TV is somehow strangly screwing the test.

No lag with a wired controller is also strange, you should get a least few msec, or it means that your TV is as fast as a CRT monitor which is unlikely.

When playing online, there will often be 1-3 frames of lag anyway. Does the lag from playing online add to whatever lag comes from the TV?

Or that his TV is from the future!!!

That or he’s trained himself to hit buttons early when does the test on the wired controller.

You decide.

Yes if you have some network lag from Internet, the data are received later by the xbox ethernet port, then it is sent by the 360 to your TV input. At this time if your TV lag as well (time it takes between the data input and the screen output) you’ll add this lag to your overall gaming experience.

However the guy in front of you on Internet is not affected by your TV input lag, he’s only affected by the network lag.

Only you are affected by the TV input lag.

Continuing from the other thread, I had another (not very accurate) test I did with mine:

I couldn’t find a CRT around, so I tested against my Dell 2405WFP, which has a lag of “45-50ms” if you go by numbers on other sites. I have heard of people getting as low as 30ms on the 2405WFPs, but the normal number is about 45. If the 30 figures are true, that’s pretty kickass though. =)

My Aquos was consistently 16ms different from the Dell… in “Dynamic” and “game”.

So in a crappy-ish test, it puts the TV at a similar number to Rock Band 2’s test.

I’ve also done the RB2 test on a CRT, which registered 3ms…so it seems to work.

I have a dell fpw2405 and I tried hooking it up to my ps3 via component.

sf4 was unplayable… major lag. I hooked it up to an old 13" aquos lcd. not as pretty but very little lag. I cant even notice it now. \

after owning this monitor since 2005, Ive come to the conclusion it blows for gaming.

I have access to both a Samsung LN40A630 and LN40A750. I’ll update this post with the lag figures when I have a chance to test.

But, so far, I’ve played SF4 extensively on the LN40A630 using HDMI2 in game mode, and the lag is pretty minimal. Picture is spectacular.

Can someone please explain why Game Mode has an On/Off feature? Why can’t it just be integrated into the TV at all times? In other words, what is the advantage of having it on Off when you aren’t playing video games?

Improved image quality. Turning game mode on can disable some of the smoothing features built into HDTVs. Image quality MAY suffer but lag is usually reduced. It’s not like you really care about input lag when you’re watching a movie or a television program. You just gotta remember, most people are buying a HDTV for those reasons. They don’t care if the image is off 25-36 milliseconds. They just want it to look good.

I’ve just found out about a site that features a comparison page where monitors can be compared to a CRT in terms of input lag. The monitors being compared in the two links have the lowest of input lag out of all the others:

I don’t know how credible their information is but even if the numbers aren’t spot on it still does give a good perspective on the general standings of some LCDs. Now if they could only make a similar chart for HDTVs (30"+).

Does using the composite cables on the TV eliminate lag? I just used the lag test on GH3 (PS2) on a SD and the 32" Olevia HD (both using composite cables) and, unless the 0 ms at the bottom doesn’t automatically change to calibrate for it, seems there’s little to no lag.
