The New Definitive HDTV Lag FAQ

Good shit man let us know. They are nice but the lack of info is discouraging.

Latency wise, LED LCD’s are EXACTLY the same as regular LCDs.

LED LCDs are not a radical change like OLED monitors. LED LCDs are merely LCDs that use LED backlights instead of compact flourescent backlights.

Color gamut is different. Pixel response is still all about the processing and the panel, of which LEDs make no difference.

Read my post on LED LCDs. The lag is by the processing and a little by the panel, not the backlight

That was my initial theory I had when buying cheap ones! Feel ripped off!!! What would cause the voice and audio to be out of sinc?

in case any one is considering getting a budget tv, I got the dynex 42" from best buy (DX-L42-10A) and it has very little input lag, exactly the same amount as my 19 in lcd computer monitor. dont’ get the insignia though, i could see the input lag on that one ((NS-L42X-10A).

Hi,

I’ve been reading through the thread trying to find some advice regarding a new digital signage monitor, but haven’t unfortunately found anything about this particular model: Samsung 40" 400MX-2 http://www.samsunglfd.com/product/feature.do?modelCd=400MX-2

WOuld this be a wise choice in terms of minimal input lag?
It will be used mainly for gaming with a PC (90% MAME emulation), XBOX 360 and then also as a main PC monitor (internet, movies, etc.)

Any advice?

Thanks!

i imaging the input lag would be good, but i doubt much better then say the dynex, and probably costs at least double

The thing is that I live in Norway and there’s probably no chance to get a Dynex display here… And since this is an overpriced country the Samsung 400MX-2 is one of the only options I have in that price range (1600$) otherwise we’re talking about more than 2000$…

I couldn’t find any review or any feedback from gamers online, so any info you guys can provide would be very helpful.

Source?

I have 2 Insignia LCDs (42" and 47") and neither of them has input lag that is noticeable. I can land 1 frame links all day long without issue.

I’m definitely happy with my Insignia LCDs.

To spektrum and mega biceps,

Is there a way you can test your monitors and post results?

i dont have guitar hero, rock bank or any other method to give substantial test results. not unless there is another method of testing lag at the moment that i’m unaware of.

Also, this has been said a million times and will be said a million times more: The ability to land 1-frame links or not says nothing about the input lag of the monitor. Humans are designed to compensate for input lag, particularly in situations that are more focused on matching a rhythm rather than reaction time.

That said, someone should build an input-lag tester – just a device with a light detector that outputs a signal through VGA that flashes a full-white screen every X seconds and tests the response time for the brightness change.

This means NOTHING without testing… Yes you can get used to input lag but it is still there!

Hmm, this gets a yes and no in my opinion.

While links are largely based on rhythm, I recently swapped out my (laggy) LCD television for my smaller, less laggy desktop LCD panel. The results were interesting. The immediate feedback provided by the more responsive screen when performing attacks allowed me to be a lot more precise with my timing and did away with a lot of the compensation that I have subconsciously built into my play style. Some links with Akuma for example I found I could execute a lot more consistently solely because the feedback was so much snappier. Its very difficult to put into words. There is a rhythm element, yes - but the immediate VISUAL feedback also helps. It quite literally felt like my characters of choice had all lost a bit of weight as they didn’t have that ‘sticky’ movement I associate with input lag.

Conversely, it threw a LOT of my game off. I realised that I have a lot of timing and combos based around the laggy response of my television which is very irritating. Sure, on my TV things come together well, but on a different screen that exhibits less lag things require a bit of reworking. This is perhaps the part that annoys me most and it makes transitioning to a different setup a bit odd.

Is this an excuse? No. Its moreso a comment on how different things can be between various setups with respect to input lag for the exact same game. Your sense of input rhythm can be thrown off when using a responsive setup when you see just how immediate things are being represented on screen.

It does come down to individual sensitivity though. Some people can also adapt quite easily. While I feel I can personally adapt, the fact that I am acutely aware of the problem I find very annoying. LCD televisions are fantastic yet flawed piece of technology when it comes to gaming :smiley:

I notice you have an Xbox if your gamertag details is anything to go by.

My understanding is that a Guitar Hero demo is available on the Xbox network that includes the lag calibration tools. Perhaps you should have a hunt around and see what you can find. I’m a PS3 owner personally, so I am not certain - could someone perhaps confirm for me?

The second benefit is that Xboxes are able to be configured to output ALL games at a nominated resolution. In most instances, this includes the ability to match output from the console to the NATIVE resolution of your television. This alone reduces input lag significantly as the television does not need to scale. You can reduce this further by using a VGA cable and then AGAIN by using your television’s ‘Game Mode’ or equivalent setting.

Things to try:

1.) Download that Guitar Hero demo and use the lag calibration tool
2.) Repeat the above using different forced output resolutions/upscaling from your Xbox (e.g. 720p forced, 1080p forced, etc)
3.) Try the above using HDMI, VGA, component cables, etc

I personally think Xbox owners win this war. The ability to force output modes to match that native to their television’s is a huge advantage towards dealing with input lag combined with an official VGA lead they can ALSO use.

PS3 owners by comparison are somewhat fucked. Forced output resolutions are supported by only a handful of games and SFIV isn’t one of them.

Personally I think landing your average link isn’t about visual response, it’s all muscle memory. I actually find that after practicing links for a while, if I concentrate on the feel of the timing more than watching for visual cues I have success. I’m sure not everyone is the same though. Some long links require visual stuff though, like Blanka’s c.mk into ultra link… lag should be more obvious with those.

I hooked up both to hdmi ports (well the monitor to dvi) and ran one of those response time tests where you play a video of time including microseconds. Took a picture of both screens in the same picture, and they displayed the exact same image everytime. therefore same response/input lag. Very happy with the dynex so far

I didn’t do any concrete tests on the insignia, but it felt like there was input lag but it could have been just me. It was more expensive though and the uniformity was so bad it looked like there was lights in the corners so I took it back anyway. This was the NS-L42X-10A model, and i’m sure all insignia’s aren’t the same. It had other redeeming qualities though and I wouldn’t put 100% confidence into my input lag “feel” for this tv.

was it against a CRT monitor?
