That was a motion smoothness rating, not a motion clarity rating. I should have, clarified.
The 144 Hz Asus has very "smooth" feeling motion, but of course the motion clarity does not compare to the FW900. Maybe a 6 or 7 out of 10.
My finger is hovering over buy from Amazon right now tho =] (£220 delivered is a steal).Good to know. Eagerly waiting your review of the Benq
That's the non-lightboost PWM strobe rate. So, yes, the strobe rate isn't a problem. PWM has been using high frequencies (e.g. 360Hz or 420Hz). However, doing a single strobe per refresh, reduces brightness a lot. And doing one strobe per refresh does annoying flicker at lower refresh rates, costs more to do extra LED brightness (and potentially creates lots of complaints if done by default). Monitor manufacturers are probably leery of doing single strobes per refresh without a good reason (e.g. 3D, and cost premium of the LED's needed). However, as long as it's a setting like LightBoost is, and if it can be simplified & marketed better...
You should have tried the LightBoost2 trick.
Please keep us updated!
A better way to measure is to use an oscilloscope connected to a photodiode. A simple USBee or USBee clone oscilloscope, can provide you with pretty graph screenshots that's more-or-less microsecond accurate. You don't need a high-end oscilloscope capable of hundreds of megahertz, or even gigahertz, to do simple oscilloscope measurements of LCD screens with a photodiode. For bloggers like me who want to do tests, a cheap $50 oscillscope (clone price, not original USBee price) will do for this type of basic measurements, you'll still get sub-millisecond resolution.
Are you able to read text even at the maximum speed? Also, with a strobed backlight and a framerate matching refresh rate, motion blur is directly proportional to strobe length, instead of refresh rate.
I find that happens on a CRT too, when you're running at say, only 40fps @ 100Hz. The zero motion blur effect is gone.
Nada, nada, nada -- any custom resolution (Even -inbetweens such as 115Hz) immeditely extinguishes the LightBoost2 strobes. Sadly! You're stuck with the predefined refresh rates above 60Hz for LightBoost. I'd love to have 85 Hz LightBoost2 for Crysis because that way, I don't need as powerful a GPU to get the zero motion blur effect for some games. Although at 85Hz, the strobe lengths will probably become longer, and that will cause more motion blur. Perhaps it can be "hacked"; some of us will need to try.
I think it's monitor dependant if different LightBoost2 monitors have different strobe lengths. For strobes of 1/500sec, and with human eyes that can track fast enough, you could go very far beyond 20. At higher speeds, it is almost becoming a human eye test on a CRT, even at 20, so the same human needs to compare a CRT and the LCD. A person like Vega, with experience going all the way to 30, will need to try this and report back. Not all of us can even reach 30 on a CRT simply because it's too fast for some people, even though there's no motion blur.
The best I've ever got from an LCD at 120hz was 8.
With the zero motion blur modification, the LightBoost2 tweaked monitors has much less motion blur than the world's fastest plasma displays when gaming at 120fps@120Hz. I've been to the store and saw the Panasonic 2500Hz FFD (that's far more than the plain jane 600 Hz drive), and it's hamstrung by the RG phosphor decay which is 5 milliseconds. The LightBoost2 strobes are far shorter than that, and it really shows to my eyes.
I've seen those too, and the LightBoost2 monitors are far superior. It's night and day. I hope this tech arrives in HDTV's. Unfortunately, they don't support native 120Hz (only 60Hz input) because full-screen strobes are extremely flickery at 60Hz. So they need motion interpolation, which has artifacts and input lag. That's also some of the artifacts you are seeing.
Only if they are true interpolated frames (like the Panasonic plasma which uses motion-interpolated subfield refreshes). The cheap "600Hz" plasmas just repeat the same frame 10 times in a ramping-up subfield strobes; subfields are used for the purpose of temporal dithering. They DO NOT always improve motion.
CRT users know 60fps@60Hz looks much sharper than 120fps@120Hz on traditional LCD. Once you begin to strobe the backlight, things behave very differently. Motion blur becomes directly proportional to strobe length, so you get far less motion blur using 1 millisecond strobes at 85fps@85Hz, than with 4 millisecond strobes at 120fps@120Hz. Science & References.
I think it goes up to "25" now, but it depends on the person's ability to track eyes.
subb'edI didn't say that. I've mentioned a few times that there is the faint 1% ultra sharp trailing image chasing after a sharp moving image. It's similiar to the crosstalk between eyes in 3D shutter glasses. Better 3D LCD's will make better zero motion blur LCD's.
You need 120fps@120Hz for the best zero motion blur effect. You could lower to 100fps@100Hz. You might be fine with older games, e.g. Source Engine at slightly lower detail level. You won't be playing Crysis with zero motion blur on a 580, or even a single 680.
