Input Lag of various projectors - Page 3

like samsung, they have titled the new chip with the fastest response time you have ever seen, 0.0001s or something like that

I'll believe that when I see it! I can't fathom how more steps in processing could make things faster (not that anyone's claiming it will).

I guess one theoretical guess would be:

-Has anyone tested a slow Pixelworks device?
-Has anyone tested a fast Reon or Realta device?
-For the other ones, like Sony, how are they? (these projectors with custom chips are rarely tested it seems)

I just know that whatever's in my Dell 24" monitor should be banned from existence. Massive, crazy lag, completely unusable for 2D gaming, at any resolution. My previous monitor (Samsung 21", 2003 model) was actually pretty good for speed, but it had much worse blurring.

Realta's are programmable devices, so based on what you ask them to do, they will be variable speed. The Reon on the other hand is a fixed function device, however it can be configured in several ways. I can't speak for the Realta, but the Reon in my experience is slow. All devices will Reon's that I've seen have a minimum of 2 frames of delay and sometimes more - up to 4 frames. If you make the Reon run in close to a bypass mode it is much quicker, but still causes a delay.

Hopefully Yodobashi Camera gets around to changing the lamps on the Z2000. Since it's using the same processing as the Z3000, it should give us a general idea about how the Z3000 will perform.

Maybe it's about time you earn some Suica points and hop on the JR and take a trip to another Yodobashi.

Great thread, I'd love to see some info on the Sony vpl-hw10.

Has anyone thought of contacting Sony, Epson, Sanyo, etc and passing this thread along to them? If one of these emails get to their engineers, they might take things more seriously, or start advertising if their results are good. It's just one more thing for them to improve on and differentiate their product over each other's.

the inputlag from the sanyo z2000 and the new mitsubishi hc5500 are above 80ms, like the benq w5000. for me the infocus x10 is the ultimate full hd gaming machine and i am very happy with it. but hurry, in europe the prices have been gone up from 1200 to 1450 in the last two weeks and i think i know the reason, because its a great projector and every pence worth

Where did you get these numbers? Link?
The Z2000 is using Pixelworks, which you even said yourself was fast.

Yeah, good question! If you've tested the Z2000, let's see some pics. It's hard to believe it's that high based on previous experience.

Problem with AVS forum is that SO many people own these machines but not many want to test things and post pics. Maybe we should beg in individual model threads?

VERY good idea.

At least worth a try, eh?

Well.... I've had no luck. :/

Those owners are of no use! It's the people who WANT to buy that are the curious ones....go figure.

im really interested in hc5500,but input lag is really that high ?? can it be calibrated by switching off some features ?

Im sentive to lag especially in fps like halo.. I used to have samsung lcd tv a656 and lag was annoying without game mode, so can anyone compare to this tv ?

I bought the Epson 1080UB. Coming in a few weeks (on backorder). Can't wait to game on this thing! I will post benchmarks for lag, since no one else seems to want to do it!

Aww man, I just tested my friend's 1080UB and the lag is so bad...






Ok, ok, I'm just kidding!
Please do let us know the results and your personal opinions. Congrats on your new toy.
The 1080UB is using Pixelworks DNX, so I expect the results will be good.

You gave me a mild heart attack there! Damn!

I'll test it and put up the results right away. I just can't wait for this thing! I haven't figured out the size I'm going to project yet, but it's going to be spectacular.

I always find it nice to decide on a screen after your PJ purchase. It gives you more freedom and confidence to decide on what size and gain you want.


Out of curiosity, I'm dying to know how the input lag is comparing the Epson 1080UB and the Sanyo Z2000, because they're both using the same Pixelworks DNX ICs.

It's a shame that those happened to be the two PJs that Peeter couldn't test at Yodobashi Camera.

Awesome, can't wait! When we start getting some photographic evidence, we'll have to clean up this thread because it's more discussion than results. Would be nice if there was a thread with results only, for quick reference. If need be, I can even host a page on my website.

Just found this short German article on the Sanyo Z3000 120Hz PJ:
http://translate.google.com/translat...y%26as_qdr%3Dd

This roughly (poorly) translated portion makes an interesting note that further solidifies my confidence that the Sanyo PLV-Z3000 with the Pixelworks DNX will be the gamer's choice out of the big 3 120Hz contenders this year.

That's great news. Pixelworks is the new Corinthian Leather, the new Grey Poupon!

All this study of input lag just hurts my head. In the end, I say to myself, "I want to play video games on a giant frickin' screen and I want the character to jump when I press the button. The end."

All this talk between different models and brands, I mean - pick the best one you can afford that meets your lag needs. That's about it. Luckily it's turning out that there's a lot to choose from. Definitely not the same story in flat panel TV land!

anyone know about inputlag of epson HC 720 (tw680 in europe) ? all epsons look preatty good with low inputlag.. but i dont know about exactly this model, so ?

thnx for answer

The short answer is that it's using Pixelworks, so I'd say it's a safe bet that's it's a great PJ for gaming.





After all this mind numbing research, it seems that the unanimous results show that projectors using Pixelworks processing always seem to be great for gaming.

thnx for fast answer .) im gonna take this piece, probably tomorrow

Very lucky, indeed. I've gone through so many LCD HDTVs it's ridiculous. I was blown away by how fast my last Epson projector was. It was one of those unreal moments, I almost believed that you couldn't get a display with honestly minimal input lag other than going the CRT route.




I truly do hope that projectors don't all go the route of the Reon in the not so distant future. I'm not going to kidd myself though, Pixelworks is old tech. It just so happens to fit the gamer's needs. Heck, I say if it's good enough for the 1080UB and Z3000, it's good enough for me.

It *almost* baffles me that recent LCD TVs with specific Game Modes can't compete with LCD projectors that don't have a Game Mode. What's the most recent LCD flat panel HDTV using Pixelworks? The only ones that comes to mind are the 2006 Olevia 3 series 720p displays.

Maybe the processors in flat panels TV's are NOT the weak link? The game mode can bypass time consuming processors task, but can't speed up the panel itself. The LCD chips used in projectors have generally been pretty fast, but the panels in LCD TV's have not. 2 different techs with similar name. This is just a guess, I'm no expert....LOL!

dlp can handle resolutions with up to 85hz. lcd can´t - they will only accept 60hz and if you have played 10 years on a crt monitor you will feel the difference.

I don't believe refresh rate has anything to do with it, or even panel speed. I think all panels are faster than their processor. What's 85hz or 120hz do the output from your console is still 60hz? The Sega Game Gear, like 18 years ago, had an LCD screen that was instant, as did the NEC TurboXpress system years before that. LCD panels are fast enough for anything. Their colour changing speed is a different story, but I don't really care what colour Mario is, I just want him to jump on time!

This is all 100% video processor dependent. LCD monitors got slower before they got faster a few years ago. I've used some late 90s LCDs and they were instant, my 2007 Dell - garbage. Panels have only gotten better since then, processors have only gotten more to do, hence slower.

Over at behardware.com, one of the few professional reviewers that regularly does input lag tests, I've noticed a trend: the larger panels tend to be laggier than the smaller panels. The first 0-lag LCD they tested was 19". Since then, they've found others, including some larger ones, but the general trend holds.

I'm not sure why panel size would affect lag, but I think it's interesting to note that projectors, unlike flat panel TVs, have very small LCD panels. It's just the projected image that's large.
