I currently own the Pearl and Im looking to upgrade latter this year. I play a lot of games and Im wondering if LCD is better then LCOS for motion. The Sony doesn't leave any trails like the old LCDs would but the picture does get softer when panning in games. I can also notice it in movies, but it's not that big of a deal in movies.

I had the Benq W5000 DLP and the motion handling on that sucker was perfect. NO loss in detail at all while panning. The Rainbows bothered me enough that I returned it, and now Im looking for the next best thing. I know the new Epson is 120hz which should improve things significantly, and I was very disapointed that neither the JVC nor the Sony would be offering 120hz.

Does anyone know what the response time is for LCD projection? I know the LCOS are measured at 2.5ms, but Ive never heard what LCD ms rating is.

I think you should worry more about lag for games, 120Hz modes add lag.

you can turn off the frame interpolation feature on 120hz sets, which would reduce lag, and the set still runs at 120hz, which reduces blur. I own a Samsung a650 LCD and it still has less blur even when frame interpolation is turned off. Im curious if a 60hz LCOS would be better then a 60hz LCD.

I think you should worry more about lag for games, 120Hz modes add lag.As conan48 pointed out, you can turn of the frame creation options on 120 Hz projectors, and all other things being equal, a faster refresh rate should help with image lag.

Even though I've currently ruled out LCoS because I need 40%+ horizontal lens shift, I'd also like to hear how it handles motion and what kind of image lag it has. (If the differences were compelling enough, I could go HD350 instead of Epson's TW4000[6500] projector.)

for gaming, with zero inputlag and for me with no visible rainboweffect (6x speed) i would advise the optoma 800x. the only negativ point was for me the loud fan so i have sent it back and now searching for a new pj.

the infocus x10 is good too, but has a visible rainboweffect.

mabye i will try the benq, could you please say something about the inputlag ?

i wouldn´t recommend lcd pjs for gaming, they have a inputlag and visible blurring, dlps have always the best picture.

I've seen elsewhere that DLP has worse input lag than LCD, but your post is the second post I've read suggesting DLP has an advantage with input lag.

I would really like to know if you have anymore information on that. CRT level input lag would cause me to talk with my wife again about the possibility of ceiling mounting.

yes of course.

the lcd pj (sanyjo 2000, mitsubishi) that i have tested have a noticeable inputlag. i have tried some games (call of duty 4 online, grid) and playing wasn´t a pleasure, furthermore you could see blurring, like on all the other lcd tvs/tfts and that is a nogo.

then i tested the tweo cheapest dlp pj (optoma 800; infocus x10) and was amazed how clear and without any inputlag they played.

but you have to send 720 or 1080 resolution, otherwise you will notice a very very light inputlag. a other advantage from both dlps is that they accept 85hz in lower resolution (1280x720), the lcds only 60hz - so won´t notice the jaggies like on most lcds.

both dlps have a "cheap" and "old" electronic, maybe this is the reason ?!

i have attached some shoots from hd source. pj is the infocus x10. if you are a gamer please try out this 2 pjs. they are every penz worth.

What technology is better if you suffer from motion sickness? Just kidding. :) Interesting read.

What about adding a DVDO Edge video processor for gaming.

The Edge has a game mode, DVDO says it can reduce video delay to less than a single frame.

There is also the new Panasonic AE3000 that has a built in game mode.

I havn't noticed "blurring" or "inputlag" on my 8 yr old Sony vpl-vw10ht front projector. I am not saying there isn't any, I just havn't noticed. I know ignorants is bliss, but since I am upgrading soon I would like to see what everybody is talking about. What do I look for? I have COD4 and other games. Is it more noticable in certain games?

Does anyone know what the response time is for LCD projection? I know the LCOS are measured at 2.5ms, but Ive never heard what LCD ms rating is.

I would think the response time of the LCD is, or could be; very close to the LCOS.

Basically, LCD and LCOS use the same liquid crystal technology. The difference between
the two is that with an LCD the light transmits through the LCD, whereas with the
LCOS, the back side of the crystal has a reflective electrode and light reflects and leaves
the LCOS from the same surface it entered.

That difference in geometry doesn't have anything to do with the response time of the
liquid crystal - so the two should / could be quite comparable.

No one has mentioned the sample-and-hold effect of lcd/lcos. A DLP with good dithering should have an advantage here.

Yes. The sample and hold effect is what causes blurring. I read that DLP mirrors refresh thousands of times per second and that it is actually faster then even a plasma!

The Benq w5000 is an amazing projector. With the new firmware it can also be professional ISF calibrated with full color controls. Im tempted to just buy the Benq again and live with the rainbows. I did not notice any input lag at all on the Benq.

Actually, since the light enters and reflects off of the LCOS mirrored backside, the LC layer thickness can be reduced by 1/2 to achieve the same degree of polarization as a straight through transmissive LCD panel. The thinner LC layer reduces the response time. So I would think that LCOS would be better in this respect.

Agreed. I think if LCOS uses black frame insertion that this would help a great deal.

I lived with both lcd and lycos and to my eyes lycos handled motion better. Yet, still below CRT or even PWM levels. LCD suffers most when switching between narrow tonal values. Most manufacturers advertise on/off (black/white) response time, but grey-grey is much slower since less voltage is applied on the panels. Silicone with LCOS improved on this. SAH is another factor but I have yet to see serious studies analysing the extent of its effect on motion blurr and how difference is perceived among different viewers.

the infocus has problems with the rainbows too, according to some users from another forum, the benq w5000 has less rainbow than the infocus. so i will try this one too. i hope it has equal inputlag like the cheap ones.
