Reply With QuoteI have absolutely no idea what input lag would be, and I have a 2407WFP and a 2005FPW. Both look fine to me both in and out of gaming. What am I supposed to be looking for?
So here's the thing, I got tired from my 19 inch TN Samsung. And I've put my eyes on the Dell 2408WFP.
But I got some warning about it's input lag (around 50ms). Since I assume a good deal of people with 2408WFP (Or 2407WFP) hang around here, I thought I'll ask:
Is the input lag noticeable? Does it annoy you when you work on the desktop? Does it disturb gaming?

I have a 2407 and have been quite pleased with it, but from what I have read the 2408 is a stinker and you should avoid it like the plague till the next revision gets reviewed.
I love my 2407.. no problems with it at all. (Well, ok, there's a firmware bug that doesn't let me run 1600x1200 in aspect mode, but that's minor).
Input lag is the lag from processing the image by the monitor, there are some movies in youtube showing the effect.Originally Posted by Equisilus
I'm trying to figure if it's something that you only noticed if told about.
I can try finding a 2407 around here. What's bad about the 2408?
So I went to YouTube and checked out a few videos and whatever the issue is, I can't see it. If there's any lag, it's only going to be noticeable when you compare side-by-side and if it's so subtle as to be unnoticeable even when you are looking for it, then I don't think it's an issue at all, despite the claims that go with the videos.
I even watched a couple twice to see what I'm missing. Guess I got old eyes.
you may get input lag because it's not the fastest of panels, it's PVA.
S-IPS and PVA have fuller colour, better viewing angles but at the cost of response time. TN panels lack the former 2 things but are better for gaming.
You don't see the lag here?

Seriously?
I've never seen a 2408WFP in person, but if the lag really is 50ms, as reported above, that is very significant. I wouldn't even bother trying to game on a monitor whose response time was more than 20ms and even that is really pushing it. Having said all of that, the official specs for the 2408WFP claim 6ms response time, so...what's up with that?
the x ms measurement is not honest or directly 1:1 between different panels.
www.digitalversus.com has a great test comparison chart:

ie, comparing my old vs my new monitors: http://www.digitalversus.com/duels.p...4&p2=2943&ph=1
Oh, I'm aware of that. A lot of people fudge numbers by reporting different levels of 'grey-to-grey', etc, but there is such a huge gap between 50ms as reported above and 6ms. I didn't know the marketing was *that* shady.
That's certainly a better comparison than the videos I was watching. Thanks for that, as it does make it quite a bit more obvious. At least I know what we're talking about.
Again, though, if it's only noticeable side-by-side, what's the real world use issue? FPS games?

Any games where there's a twitch factor involved, really. If the delay really is 50ms, then you'll always be seeing three frames behind where the game really is at 60 FPS. That's easily the difference between something being in your crosshairs or not.
There's two different numbers here, I think -- one is the panel response, how long it takes to switch a pixel from one color to the other; the other is processing response, how quickly each frame gets to the panel from the input. If the former number is bad, you get ghosting and smeary displays; if the latter is bad, it looks fine, just a little bit after it should have been.
I'm not sure whythe Dell would have the delay like that -- video processing for TV purposes?
What mkozlows said. The 6ms if the time between two frames (More exactly grey 2 grey time of a pixel).
Input lag is from processing, apparently all bigger panels come with worse input lag, but the Dell has a rather bad one.
And supposedly it should disturb you in FPS games.
The question here is are there any owner of such screens that actually experienced something like that in their gaming?
If barely none of those exists, I'll happily buy this rather cheap 24 inch screen with a PVA panel. The next in line I found cost twice as much.
FWIW, I've had zero problems with my 2407 with input lag, and it's my primary gaming display.
There should be an A01 revision of the 2408 available now, that deals with the input lag problem:

I got my friend to buy a 2408 based on reviews and my own 2407 experience. He hasn't complained. Maybe he got an A01, though; dunno. If there was/is a problem with A00/all models, I wouldn't be surprised, cuz the early 2407s had issues too - banding, for one.
I'm asking him again.
OK, well, I just asked my friend again and he says he still hasn't noticed any lag. He bought his last month. He says he couldn't find the A00 or A01 tag, but that it was May '08 manufacture.
Sounds like it's a good buy. I want one myself, but my 2407 is still in good shape.
Great, now I just need to find one around here, luckily they listed a simple way to know (I assume most vendors here won't know to differentiate between them and just say they have the new one).
Hopefully I can find one as fast as possible.

Sorry for the bump, but I am researching the 2408WFP and came across this thread.
First thing is that the input lag was introduced with the 2408, it was not a problem with the 2407. The 2408 also introduced the problem with a brighter left side of the screen to the right, and some sharpness of fonts problems. So you can't consider them the same monitor, there are quality differences between the two.
I have yet to read that the A01 firmware actually fixed any of this. It did not fix the left/right brightness. Input lag I haven't heard anything that it has, but it isn't something you can really tell unless you see a direct comparison. You may not notice the lag, but it is there, which is very obvious from the Youtube video and some of the other review videos. I have read reviews saying that it is noticeable, and others saying it isn't, but they seem to all agree that is a frame or two behind.
Also if you buy now, you may still get an A00 version. A Dell rep said on the official forum that they are still trying to the A00 out of stock before they can guarantee you will get an A01. In fact salesman have promised an A01 and the person received an A00 in at least one case posted on the forum.
I bought a Samsung T240 last week, and it was beautiful for gaming, but a TN's viewing angle is horrible. Just surfing the net there was a noticeable difference in contrast/color from the top of the screen to the bottom. I got so annoyed by it, I sent it back. Games did look beautiful on it though.
PVA is the way to go in my opinion because TN is horrible for viewing angle and IPS is just too expensive still. I plan on buying the 2408WFP, I am just waiting for them to iron on the problems.
You can identify one when you see it. And I won't buy a screen without opening it anyhow to save me past troubles of going to replace because of dead pixels.
Anyhow, there isn't any other PVA paneled screen at this price range. I'm still trying to find a vendor around here that I can get a new one from. Probably will take some more time.
