Does your LCD have input lag?

Not to mention that I have really a hard time clicking everything on the desktop. I miss icons, start, -, x, and all possible buttons all the time.
CRT was much more smoother in this regard and it helps nothing having a G5, G7 mouse. All same.
The video input lag in games I could get used I guess. Just played CSS and had the second best score on server. I was shooting so good that people vote banned me for cheating already lol so looks like games wont be a problem. But I did compared a video on CRT and LCD on my computer and the LCD was behind abit. I guess the biggest problem is if the lag isnt constant like seen on the movie then thats horrible but mostly not a problem to play at all on this 215TW.
Also I heard that sound has lag to since this monitor has a speaker under but I havent tested this yet and dont care.

The mouse disappearing (getting darker) as you move it and reappearing as it stands still is a response time problem (rise time is too high). Overdrive can help that. I believe the 215TW does have overdrive, just not a whole lot of it.

Input lag (if such a thing does indeed exist) is a static lag between the sending of the frame and the painting of that frame.

I'm not talking about a mouse getting darker. Sooner mouse disappears. If you move it around really fast you can see about 4 cursors on your screen. But i just checked on CRT it looks same also.

Also it does not matter if a program is inaccurate or written in java or tested in windows. The setup was run from same GPU in clone mode what means so far same realtime input to both screen tested with DVI, Analog and ecetra and CRT was always faster no matter what you did. But why I'm explaining the obvious again and again anyway when someone new joins the discussion. Its like talking to a solid wall!


I also know of no way how to cure this. It probably isnt even possible but some test were made forcing windows to update with 100Hz instead of 60Hz which looks like made the delay a little less but well this aint by no means scienc tests so I dont know if it really helps since I cant understand how. I also dont know how to make windows force 100Hz input you will have to ask this people here. http://www.hardforum.com/showthread.php...26393&page=1&pp=20&highlight=input+lag

The problem with clone mode is the resolution scaling, if it's present. But on the other hand, it's bad thing also if it causes delay.

Someone said that reducing dvi-frequency and disabling the other related option in ati drivers helps, but no one has tested it yet.

Of course it matters how accurate the program is. You will never know how many milliseconds behind it was if one frame stated '50' and the next stated '52' and the next stated '53'. It's inconsistent. You will only know if it was behind or not.

well thats a fix to fix some pad pixel colors in game and not for input lag.

well report when the English version comes since this is really hard to read.
Also the pictures are pure white for me just borders.

I have to step in. I'm getting so frustrated by the people who don't see or wants to believe in the input-lag problem. I bought a Samsung 214T LCD screen and the first couple of weeks I thought I had gone crazy. It felt that I was constantly drunk or something even when doing simple things such as moving a window. HOWEVER, my girlfriend never noticed it. My friends said "hmmm _maybe_ there is something wrong -- the mouse?". Putting the CRT and LCD and output on Clone was what eventually made me sell the thing.

The people who don't notice it/believe it won't do so until we get this widespread attention from reviewers. We can post here all we want but Adam and Even who has this big nice TFT screen for surfing the web and wants to defend their expensive $$$ buy will never admit to having input lag. I cry everytime people say "it is the mouse, it is the DVI out, it is yada yada". No it is not, it is the slow DSP processor inside the LCD panel that cannot handle the amount of data.

So please, please, please, REVIEWERS, help us with <20 ms responstime to buy a screen we can use

No, you wont notice it on small LCDs.

Someone measured the 244T vs 3007WFP. The latter is 33-53ms faster! Now I wish they'd compare the 3007 vs a CRT, but I think they'd be very close.

Monitors that I've used:

with noticeable lag:
Dell 2001FP (2)
Samsung 244T (2)

without noticeable lag:
2007WFP

The difference between my LCD and 21" Trinitron is nite and day. Its frustrating to play Q3 on my LCD because the disadvantage is huge esp w/ Railgun. I play RA3 against a friend and I spank him like a red-headed stepchild on my CRT. On my LCD, that red headed stepchild occasionally spanks daddy For me the disadvantage for gaming on a LCD is outweighed by its advantage of less eyestrain while not gaming.

I just don't FPS much anymore except UT2K4 and I usually avoid dueling 1337 playas and just hop on a mantra. The silver lining of lagged response on LCDs is one more excuse when getting owned instead of just being a man and acknowledging the better player. Bro, if I was on my CRT I would 0wn j00!

Dude this is SO true. I got a Viewsonic vp171b a few years ago to replace my 17" trinitron that was failing and noticed something was amiss right away. I couldn't hit anybody with the RG in Q3, and I went from being one of the best players on the server to middle of the road. It was so damn frustrating! Eventually I got more used to it and my play improved, but I was never quite as accurate as before. Now recently I got a Samsung 215TW and the problem is just awful. I don't notice a problem during normal windows use, but when I play Q3 or Q4 I can't hit anything. And people seem to frag me without even hitting me. This thing also ghosts much worse than the old viewsonic.... my online gaming experience is serverly affected. I love the monitor, it has a beautiful display, very crisp and good blacks, but is almost worthless for gaming in my eyes. Anyone that plays FPS games and says they don't notice a problem with input lag on an LCD can't be that good of a player to begin with.
