meaningless poll and meaningless values.
1) unless you actually measure your monitor's input lag with another crt in clone mode, probably 99% of the people here have no idea what their input lag is. unless they have access to other monitors of known lag values, any opinion of acceptable lag is pure conjecture.
2) all lag is can only translate into the monitor being 1, 2, 3, 4, etc frames behind the input signal. that means at 60hz refresh you can only have 0ms, 17ms, 34ms, 51ms etc lag.
3) monitor manufacturers only list response time(which is meaningless) so any input lag measurement comes from review sites which dont follow up on hard/firmware updates to the model. the dell 2408wfp rev a00 was reviewed by tft central with a 3 frame input lag. i tested my 2408 a01 and got 1 to 2 frames of lag (50% of the time 1 frame, 50% 2 frames). so what lag should be listed: 1 frame-17ms, 2 frames-34ms, avg frames-25ms?
TN panels benefit from on average faster response times, so they need less compensation delay to counter pixel artifacts from fast movement, but most of the time there is less compensation processing because they are cheap monitors and it isnt worth it to put better circuits inside.
