Does Your LCD Play Catch-Up To Your Mouse?
Dishes of Ryan writes "I fell in love with the idea of an LCD monitor, so I ended up buying a nice, shiny Dell 2001FP. However, nowhere, and I mean *nowhere* did I read about LCDs having an input lag on them. For instance, if I scoot the mouse across the screen, there is a noticeable delay between when I move the mouse and when the cursor moves. To prove it to people, made a video showing exactly what I mean. You can almost forget being king of the hill on twitch FPS games like Unreal Tournament. Are there any other Slashdotters out there that are as annoyed as I am? What did you do?"
I'd recommend popping in Knoppix and see how it works. It will probably pick an open driver made for your graphics card family. You say this happens with the mouse, what about typing?
Never, under any circumstances base buying decisions off of reviews from Newegg. Half the reviewers state they're first time system builders with no real idea of what there doing. The other half try to sound like they know what they're talking about, but obviously have no clue, or are just flat out lieing. Then you have the problem that newegg removes the reviews that are less than pleasant. Your best bet is to read a site that focuses on reviews and sells no hardware. Maybe Slashdot could start a hardware review section and do some unbiased hard journalism!

Waffle Iron,
THANK YOU! Excellent post my friend. I just created a small bmp in paint with different sized black squares on a white background, then tiled it for my background -> Autoadjusted my LCD.
It looks fucking fantastic, text is smooth and clear, unbelievable. Thanks a million man, most useful post I've read on slashdot. Note, and this isn't even at my LCD's native resolution (1280x1024, whereas I am running 1280x960). Amazing, didn't think this was possible.
That's my guess. A lot of things happen during the vertical blanking interval or on some other similar periodic interrupt. In most OSes, this includes screen updates and mouse pointer redraws. This could be anything from a buggy driver to an IRQ conflict, or possibly even a bad trace on the motherboard (though the latter isn't anywhere near as likely).
If an OS reinstall doesn't solve the problem, there's probably something weird going on in the BIOS settings and/or the motherboard itself. Pull the BIOS battery for an hour. Try again. If that doesn't work... is your clock running slowly, too? If so, buy a new computer. If not... buy a new computer. EIther way. :-p
<rant>And speaking of IRQ conflicts... why hasn't any motherboard manufacturer broken with tradition and actually added enough distinctly addressable interrupt lines? I mean, the Mac has supported 64+ interrupts on its interrupt controller since 1995. Does it really take a decade of engineering to figure out how to cascade two interrupt controllers and add a driver to support it? Sheesh!</rant>
Sigh. Another victim of a 2004 computer crammed into a 1981 architecture....
120 character sigs suck. Make it 250.
THANK YOU. Awesome trick. I put up the images as you described them. These worked for me. I did notice my LCD acting really weird when these images were being displayed. I don't recommend keeping the image on the monitor for any longer than needed. http://www.hackermedia.net/downloads/lcd-cal
