The New Definitive HDTV Lag FAQ

I finally got to do some testing on an Asus VE278Q and can confirm that it lags, albeit only very slightly - perhaps one frame. This was enough to throw me off (I currently use a BenQ E2400 HD which compares with the EVO monitors in terms of lag - i.e. none) and as such held off picking one up.

Right now I have my sights set on the Viewsonic VX2753mh-LED which is quite a new release from Viewsonic though has no real lag reviews nor information. I’d like to think of it as the LED successor to the VX2739wm (http://www.tftcentral.co.uk/reviews/viewsonic_vx2739wm.htm) which reviewed really well, but I just plain can’t find any lag details.

Does anyone here own one of the VX2753mh-LED screens? They are priced really well and check all the boxes in terms of features I am after though I just plain can’t find any input lag details (yet).

Edit: Here’s a review of the VX2753mh-LED:

What this thread needs is a list of confirmed 0 lag monitors / tvs on the front page. Or does anyone know where that list can be found?

Snip…
Anyhow, you need to get a splitter to test. Essentially you use one DVI port coming out of your video card and then use a splitter to split the signal to two different monitors; one lagless (preferably CRT) and one to test.
Clone mode doesn’t do justice because of what you’ve observed in terms of the video card driver being random.
If you can pick up a splitter, it ensures the signal is being sent to both screens simultaneously.
There are many variants (HDMI–> 2x HDMI, DVI–> 2x DVI, VGA–> 2xVGA, some weird combinations like DVI–>VGA+DVI, , etc.). Use the one that benefits your setup. Also having both monitors capable of displaying in the same resolution helps, but it obviously shouldn’t matter on a CRT.

They look similar specification-wise, but I’m honestly not sure if they’re the same.
Anyone else with info?

This is promising!

I gotta get the model number on that. But I swear, no lag what so ever that I could feel.

ok redid the test with a VGA splitter (on standard, didn’t bother to try game mode):
Results seem to range from 0-1f (with some rare 2f spikes :() of lag.

I took some at different resolutions but i figure only 1080p counts so that’s what im going to post. As I read from lagom.nl, a transition to a frame counts as an equal frame on both displays.

VE228h on the left, CRT on the right.

You can see for yourself, but from what i gathered out of 20 pics i counted:

13 pics under 16ms (01f) of input lag
6 pics around 16ms (1f) of input lag
1 pic around 32ms (2f) of input lag

So not completely lagless…but i don’t think that’s too bad a result. Maybe its the same panel as the VH222H but with LED backlighting?

720p definitely counts, since that is what virtually all PS3 fighting games output even when the PS3 is set to 1080p.

Ah ok well…here are the 720p results:

I stopped using this site because the timing results are weird (as you can see the clock and frame counters aren’t even the same. I might have to redo that one with the other clock.

Today, I was going to go out and purchase a new television, and I did a lot of reading up, only to find that all the places around me don’t have anything good for gaming whether it be in specs or the size that I need (anything medium sized, like 21 inches). I asked a few friends for advice, and all their responses were different. One friend that I do rely on asked if I minded waiting until the fall to pick up the new Sony Playstation 3D HDTV. I figured Sony wouldn’t make something for the gaming community if they didn’t know what the needs were first. When I came home to read up on it, I found a page with a list of all (or most) of the specs for the display. As uneducated as I am, I know that you can’t always trust the distributor to be completely honest, and I know that you can’t really get an idea of how good a television is unless you experience it yourself and run some tests. I was wondering though that if by the looks of the list, if it seemed worth looking into?

y/n?

has anyone tested Alienware OptX AW2210 21.5" Full HD monitor before? Just wanted to know how it stacks up compared to others

Can anyone tell me if this monitor has input delay? I can’t really tell lol. Apparently it’s the evo-monitor?

Cicada’s tests on this monitor were on the old SRK blogs which were wiped out by the forum upgrade. It has even less lag than the Asus VH236H; both were used at Evo 2010.

What monitor? You didn’t post a model number. “Evo monitor” usually means the Asus VH236H, maybe the Alienware OptX AW2210. They are both “lag-free”.

btw is there any real tests of the evo monitor? I know it’s “lagless” essentially but I kinda want to see if there are any photo test results. I want to compare them to the VE228H.

If anyone is interested in a Panasonic TC-L32X1 that has 0 input lag:

Without a comprehensive list of tested displays sorted by whether they are “lagless” or have passable / unplayable lag – this thread is not very definitive. Its frustrating, perhaps a better title for this thread: “The Frustratingly Indefinite TL;DR HDTV Lag FAQ” :wink:

But seriously, all I care about is a list of displays with comparable input lag to the vh236h and the aw2210, which im sure is what the majority of people who visit this thread are looking for only to be met with questions like “is my 82-inch samsung 3D LED tv laggy? has anyone tested it with original NES hooked up with 17 daisy-chained RF-Adapters !!PLZHALP!!!”

Im not trying to sound like a dick, i’ve just been looking at this thread for over an hour and have yet to find anything about monitors comparable to the two EVO monitors. so, plz read this knowing my apologies for my frustrated tone are attached to it. :frowning:

If you consider the resources that would be necessary to develop a list like that, it’s pretty obvious why there isn’t one here. There are hundreds of TV and display models out there, some of which may have obscure settings that affect lag, and at least 5 common video signals - which may lead to different lag characteristics on different displays.

Well I did just post a bunch of test results right above you for the ASUS VE228H…

The list of “lag free” displays most likely would not be unreasonably long. But i agree with you on the majority of the countless devices falling within the latter two categories which would cause those lists to be exceptionally long. I still believe there should be a “recommended” list or something of that sort which contains the “lag free” devices such as the vh236h and aw2210.

Do be sure to update us on your progress on this project!

did anyone ever do any testing on the ASUS VE245H? I used the search, but all I could find were other ppl in this thread trying to find out the same information as I am in terms of how much input lag the monitor has. It says 2ms GTG and 5ms Rise+Fall response time but I cant locate anything in regards to its input lag specs.

Again the TLDR version is:
“input lag is never a specification. We like to plague the market with GTG response times, contrast ratios, and refresh rates to confuse you, the customer”.
