That "input latency" is something like wireless mouse or keyboard difference between wired as I understand? I think for BW that 0,x sec. delay isn't important. What more you should bother is on which screen I can play long so my eyes won't get tired.

In other hand this "game latency" is a really good thing to fix for Blizzard for next patch. C'mon, this game can run with 56kpbs modem and everyone should allowed to play on same latency without hack/tool.

Julia will thank later...

Input latency and output latency are completely different, and usually your keyboard and mouse have higher input latency than your monitor does output latency. If you don't notice it, you don't need to worry about this.

This is StarCraft, it really doesn't matter.

Ok, make sense. Then the question remains, why is this latency option not implemented in the launchers for both players via #L3 for example. Would especially be useful for the Koreans.

Mouse input latency is usually very small when compared to the latency for a display to actually show the mouse movement

Well at least in the posted vid there are long part following a pattern, so you don't actually have to memorize each three thousand individual key presses.

This isn't an instrument, and this is too much to memorize. Your argument is silly.

I though I would post the results of my CRT vs LCD response time experiment I did when I got my monitor.

Monitors are a Dell M782 and an Asus P248Q.

Using the Response time test from this website www.lagom.nl and my cell phone camera, I captured these images.

My LCD is about 3.5 frames, or about 50ms (0.050 seconds) behind the CRT.

Does this affect my gameplay? If it does, I haven't noticed. Just thought I'd share.

Can you still record a video with 120hz CRT? You can easily record a video with OBS or FRAPS.


...OBS doesn't record the screen, What OBS records has nothing to do with the screen.. It is not some kind of video camera put infront of your monitor

Your result is messed up in some ways because your camera exposure setting was too long and you captured multiple frames in a single picture, even on the CRT. Also again to note you're using the Input Lag / Display Lag test, not the Response Time test. Those two things carry very different meanings in display technology.

There are differences in screen technology that are very relevant - a 60hz LCD, even a good one will display information for about 20 milliseconds after a refresh - LCD's continuously display the last frame until refreshed with a new one, which takes 16.67ms plus transition times.

A CRT will only display the information for about 1ms - it flashes it once, then it's done. You can't capture "old" information from it using either your eyes or a camera which has significant meaning for both

Stuff like that will give you confusing results if you don't understand them.

I guess in this picture you have a screen that's not great for input lag (unlike many other lcd's) combined with camera setting issues due to the difference in screen tech. IMO investigate the lcd more, if it's really anything anywhere near +50ms of lag then it's important. To get this result you could have 50ms+ of total lag, while an optimized system with a high refresh rate (LCD, but CRT works fine too ) monitor can get that down to 20ms or so.

A 10ms difference in lag is roughly where it becomes blind testable for me personally if you want to know how big +40ms is.

I think when the OP uses the expression "response time", he doesn´t intend it to have the meaning it usually has in discussions of display technology - grey to grey or black to black response time. What he is interested in is really input lag.

But yeah, it appears that the Asus P248Q is particularly bad in the input lag department, and that corn322's test isn´t accurately representing the typical input lag differences between a CRT and a decent LCD.

Edit: Did you edit your post Cyro? I think I wrote the above responding to a somewhat different post of yours. But maybe I´m just in the need of coffee.

Yeah, i messed something up

The page has both Response Time and Input Lag (actually more accurately called display lag in this situation) tests, the previous poster used the Input Lag test and called it Response Time

.... probably , because 24 fps has to be reformatted to 30fps for TV broadcast.

Watching 24fps on a 60hz display will be jerky. Broadcast professionals used studio equiptment to handle the conversion, and amateurs skip it .

24fps plays fine on 120hz and 144hz, btw

24*5 = 120
24*6 = 144

to get 24 to 60, you have to do 24*2.5 - specifically, you have to alternate between displaying a frame on every second and every third refresh which is very unsmooth.

I think after around 2005 they had some digital reformatting with motion estimation and "fake" frames.

120hz and 144hz displays are less than 0.1% fraction probably closer to 0.01%, manufacturers don't like giving up profit margins.

Besides , when it comes to eye-tracking blur 120fps is nearly as bad as 60hz, ~600lines vs. 300 lines equivalent of motion resolution. Not worth it.

Probably some flicker countermeasure at <100fps is better way than "mindless" >100fps .

Eye-tracking related motion blur is literally half as bad at 120fps as 60fps. It's based on the average error on what the screen is displaying vs how far ahead your eyes have tracked

Yes I know, but it is not widely known , that "normal" 120fps translates to only 600 lines equivalent eg. 720p (unless there are "fake " or black frames,and only the latter can be inserted without extra lag) also to maintain 120 actual frames without software optimization seems quixotic , so no wonder 120hz monitors never succeeded really.
