I would say your video is slow because of pushing a high resolution. Your Xbox is a computer at heart, is your Xbox running at 1900 by 1200, if so it would get slowed down too. Try lowering resolution to 800 by 600 as an experiment the lcd will look poor but the workload on the xbox and pc will be less. (I came across this video of a crt and LCD running the same game, they appear NOT to be at the same resolutions though, only fair test.)

Also its not really 'video lag' aka ghosting, its input lag, something is not processing right in the monitor as the inputs (vga included) seem to induce this delay in reception of commands. While I notice some ghosting when I play, its pretty subtle and not too bothersome, the main problem is this input delay.

Well I managed to fix part of the problem but I don't fully understand why, however it doesn't work with consoles still. True the xbox may be a 'pc in a box' but its also a streamlined and unified peice of machinery, it should work on anything and it doesn't here.

Today I messed with my video card, and other things, I noticed when on 'dual screens' using one crt and one LCD from dell, it seemed to work PERFECT on both, and when I hooked up my pc via DVI to the monitor, it seemed to eliminate lag from the pc games at least.

The problem is, my ps2,xbox,gamecube,etc, all of them experience this weird 'lag' and it makes this screen half useless for me. You can't really adjust the resolutions they output since they generally only output in 480p, and as far as I know the video card in my pc has NOTHING to do with how the consoles should be performing on this monitor, and since the monitor has little options to adjust on itself, I can't think of a possible fix.

I would like to keep this post bumped and perhaps find a solution to tell friends and family, I honestly love these dell brand monitors if not for this lag, and its obviously possible to fix if I got my pc games to work on it alright, but not the consoles.

I'm confused. Does a monitor even have a buffer? How can it not be presenting the data exactly as and when it recieves it? Either it shows the "now" picture, or it doesn't. It can't show data it received 3 seconds ago?

No, there's no 'buffer' that I am aware of, but the fact that it doesn't happen under DVI is probably a clue. DVI is straight digital-to-digital from card to monitor, both doing that 'native' thing. When you go analog then that whole conversion process kicks in - the video card has to convert the digital signal to an analog one and the monitor then has to convert it back before it can be displayed. 

That being said, I would think it really shouldn't be something you should notice. Perhaps the monitor is 'defective' in that regard? :smileyindifferent:

Well the thing is, I didn't notice it initially. Everything just felt off and I figured I was just adjusting to the new monitor. It was until I played a game that requires truly split second reaction times that I relized it was input lag.

Let me break down what I have used and maybe someone can help source a problem.

Geforce 5200 fx 256 meg ram via vga= Lag

Geforce 5200 fx 256 meg ram via DVI= No lag that I can see

Xbox via HD pack and then composite cable= Lag

Xbox with just composite= It seemed the analog sticks didn't lag as bad without the hd pack, but the buttons still did..

Xbox with HD pack and svideo cable= Lag

Ps2 through composite = lag

Gamecube through composite = lag

So thus far the only one I have not really tried is component, if component lags, I'm boned.

Did the component lag? I suspect the analog to digital conversion lags. That was interesting finding, the DVI is without lag. Take a look at this virus-fee (I tried it) movie, is this what you were getting? If so, you may not have a defect, but a very annoying quirk, I am glad to hear about! I wonder if it affects other LCD models?

Also, this page

http://www.analog.com/en/content/0,2886,765%255F%255F6981,00.html

has a block diagram, read a bit, there is an optional frame buffer shown, doesn't say if used in analog or digital. The engineers of the 2004FP know the explanation for the behavior of the monitor, for sure. Outside of the labs, the knowledge seems sketchy. Google "LCD monitor block diagram" for more. Your problem is more interesting than usual to me, as I am going to move to LCD sometime.

I'll take a look, I have not tried ANY form of component yet, I ordered a xbox 360 just for this monitor some weeks ago before finding this issue, so I will be testing it then, I pray my 1600 bucks spent on this new stuff is not for nothing.

Is it past returning? It is the biggest monitor at a reasonable cost around. Maybe you need a CRT monitor (check Ebay) like a Sony FD trinitron, or use a modern TV set with component inputs (non LCD/Plasma) for non PC games. You must be a Serious gamer! I just dabble in Flight Simulator...

After looking at the video, that is exactly the problem (ironicly the first game I noticed it in was halo 2 :p )

Now, when I play say, a pc game, quake 3 for example, via DVI, it does not have ANY such delay, it plays like a dream aside from minor ghosting (consider how fast quake 3 is though), however, in svideo, vga and composite, the problem is there.

From what I understand the xbox 360 can only output in analog, and component is analog, so I fear this delay issue may indeed plague my new console as well, if it does, I will need to either find a fix or sell this monitor, which, I really don't want to do :/
