Input Lag, Or Why Faster Isn't Always Better

Posted by kdawson on from the lag-lag-i-thought-i'd-die dept.

mr_sifter writes "LCD monitor manufacturers have constantly pushed panel response times down with a technique called 'overdrive,' which increases the voltage to force the liquid crystals to change color states faster. Sadly, there are some side effects such as input lag and inverse ghosting associated with this — although the manufacturers themselves are very quiet about the subject. This feature (with video) looks at the problem in detail. The upshot is, you may want to test drive very carefully any display boasting low integer millisecond pixel response times."

    The upshot is, you may want to test drive very carefully any display boasting low integer millisecond pixel response times.

    First of all, I'm not really sure why that's considered a "upshot." But more importantly, I baffled by the submitters implication that I would have to carefully test an 8ms lag screen but not a 7.5 or 8.2ms screen. Huh?

      What you really have to watch out for is those -4 ms screens.

      No, that's just your keystrokes battling all the viruses on your computer for CPU time.

  3. as soon as i read the word inverse ghosting i knew by Anonymous Coward · · Score: 1, Funny

    what i had to do. i have a camera pointed at my monitor as we speak and i am working on a script to move the mouse in accordance with the stock market movement. inverse ghosting will allow me to see the mouse trail from the immediate future and place my bets accordingly. i am only posting this because i am looking for an investor. as soon as the market makers realize what is happening they will delay all online tickers by just enough to remove the inverse ghosting effect, so it is imperative that the first trades be made with a huge BANG. pleaes write me at madmadgenius@gmail.com if you are interested. serious investors ONLY

    Buying an LCD is becoming a real pain in the arse.

    Perhaps, but buying a CRT was a real pain in the back.

    Modern text editors work best at at least 60fps.

    So vi is ok at 5fps, but vim needs 60fps?

    What matters is how the display looks and feel

    Yes, how a display feels is critically important because I'm touching it all the time. Except that I never touch it, as I have a strict "don't put your greasy fingers anywhere near my display, you mouth breathing moron" policy.

    Low double millsecond displays are ok?
