9100, MR9800, and LCD screen lag?

I do not get this screen lag stuff..
I have had 3 IBMs in the mid to late 90's ,a 2000 Compaq, a 2003 Sony, and now a 2004 Gateway notebook and Ihave played and still play all kinda games believe me. Never saw this screen lag. I must admidt that the DVD movie The Matrix did tax my late 99 model Compaq notebook but id just seemd to get stuck in a loop for a few seconds every once in awhile.
What is this lag can you describe it in detail ??

Thanks

My current understanding is LCD screens will have some ghosting. It is normal and screens are getting better. Hopefully in the future this will not be the case.

My WUXGA XPS has horrible screen lag as well. Strangely enough, it seems like some colors are affected more than others. Take for example the winxp loadings screen. When it is finished loading and the screen temporarily goes blank, all the color squares dissapear except for the red that fades out over say 1/4 of a second. Likewise, the display is horrible for games as well with the ghosting. Like you say, vertical edges seem to be the most noticeable. In racing games such as Flat Out for example, objects such as telephone poles are hard to discern because there are numerous copies of the objects as the low quality display is unable to update fast enough. I got so frustrated with the ghosting and other screen related problems that I sent my unit back to dell, who admitted that something was amiss with the display and sent me out a replacement. Unfortunately, my new display has the same faults as well as a string of four or five dead pixels in a row along the right side of the screen. I think the only way to go about doing any gaming on a 9100/XPS is to plug a decent quality LCD or CRT monitor into. For viewing still images the display seems to work fine, but anything involving motion seems to bring about the nausea inducing ghosting. All of my LCD screens have been Samsungs, by the way. What make is yours? If you are unsure as to how to tell what make is in your machine, check 9100/xps FAQ in the forum here.

I have a LG Phillips panel - I don't know the official specs but from gaming I can honestly say it feels like a 16ms LCD. Color is much better that I expected, as I too was worried ghosting when I purchased my 9100.

A friend of mine also has a 9100, except with a samsung display. I could tell ghosting was much worse - to me it looked like a typical 25ms display.

I play Counter Strike:Source on my 9100 with a MR9800. I notice very little ghosting, I have to place my head a few inches from the screen and specifically look at the edges of character models to see it.

I turned on vsync in the Adanced 3D options. Set it to always on. You are locked at a certain fps, but it eliminates the shimmering/tearing.

- his problem was screen lag -- having vsync off could potentially cause shimmering/tearing but not lag

I recommend having vsync off and limiting the frame-rate in games. In some games 60 frames/sec just doesn't cut it.

I have had the same problem since I installed the mr9800. It has been driving me crazy. I had the Omega drivers installed and I just replaced them with the Dell drivers. It seems to have improved. I havent tested it but for a few minuets, but it might be with a try for anyone else having problems with screen lag and tearing.

I was just wondering, has anyone tried using a program like powerstrip to raise the refresh rate on the WUXGA displays to see if it lowers ghosting enough to make games playable? I am going to be going back to my folks place over the holidays and am just wondering if there is any way around hauling my 21 CRT with me if I want to fire up a game of HL2 or Fs2004.

Radiation: Is your screen a Samsung as well? Maybe the Samsung displays Dell uses are not up to the same quality as the Sharp/Toshiba/IBM offerings. Those who don't have bad ghosting, what display do you have in your machine?

396SS: Do I understand correctly that you have a LG Phillips in your 9100?? I didn't know there was such a beasty...

LCDs don't have refresh rates.

Like what? The LCD has a "refresh rate" of 60hz. While LCDs refresh the entire screen all at once unlike a CRT, 60hz still means 60 complete screens sent to the LCD per second, and no more.

Turning VSync off is only useful when benchmarking. Turning it on prevents tearing people see due to the game trying to push 120 or so updates to a screen only expecting 60.

I have the samsung. And as and update to my using the dell drivers, It really didn't help that much if at all. At first I thought it was better, but as I got to do more testing i still have a lot of tearing when anything moves quickly on the screen. Maybe I'll give Dell a call on monday when I have a few hours to waste sitting on the phone.

In a few games being locked to 60FPS makes mouse movements feel sluggish (to me at least). I've noticed this with the original UT, COD, and CS to name a few.

What I've done was basically lock each game at 100FPS. Sluggishness from the mouse went away, and there absolutely is NO tearing.

i have a samsung lcd and i have no problems with ut2004 or hl2

no ghosting or tearing or whatever u call it

Well I have my second laptop and this screen has the infamous red fading problem. This is getting to be BS...

Whack: Are you running the IBM display? Just curious, I am trying to figure out if the problem might be related to a specific manufacturer (Samsung) or if it might affects other brands as well. The one thing I do know is that my friends Sharp display in his 9100 has no ghosting whatsoever and seems like an infinitely better display than the Samsung in my XPS. Hmm, maybe I should wait till he's not looking and try and pull a little switcheroo
