You mentioned you saw no RBE with K750. Are you very sensitive to RBE? Did you see rainbow with other 6x speed color wheel DLP of the similar movie?
Thanks for your feedback
I'm only mildly sensitive to RBE. That opening scene in Casino Royale was one where I saw flashes on my IN83. But I'm not sure what the wheel speed is of the IN83 - I want to say 5x. The K750 does not have a color wheel, so all is good.
My LG PA70G doesn't have a color wheel, but still shows some rainbows. I see a lot less if I run it @ 120Hz.
There are 10 types of people: those who understand binary, and those who don't.
even less pop than lamp proyector some user can confirm that.
Is the feel after read user opinions
even when the saturation in test is about 81%
I have the K750 and in the movie mode with eco enabled it's very quiet and bright enough with reasonable color accuracy. I'm quite happy with it.
Problem is that any tuning changes the mode to "user" with a lot more fan noise. Do others recognize this?
Second question because I can't compare to lamp based projectors. Is the fan noise in standard mode comparable to lamp based projectors?
if you selected user always change de fan speed??
I have this projector in the point of view and I am very interested in all about him.
The eco mode setting is independent of picture setting, so any picture mode is more quiet in eco than in normal.
But my issue is with the combination of movie mode and eco on, this combination is the only one which is whisper quiet. But if I increase for example contrast with 1, the mode changes to user which increases the noise a lot. I contacted Acer support with this question.
By the way, if anyone wants to access the service menu, combination is: press red power button once, down, up.
Note: use at own risk. Menu contains a couple of test patterns and calibration control, not so many different options than the standard menu.
I buy too ,
don't cant wait for pf80g less according to the price range in this moment.
I am happy, colours not quite spectacular comparing with pf70 but the projector is in another level , and either the sharpness not so good like me hc3800 and the bright scenes don't looks superb like hc3800 here is the not good things .
The good I have almost the goods of the two worlds and
the best shadow , night scenes detail than ever seen
I only have two days and not too much time with it , I have to try get better result with not so goods
Black Level/shadow detail. If i set gamma, brightness, contrast so that i don't loose details in dark scenes i get a very poor blacklevel, if i try to improve the black level i loose many details in dark scenes. I know that Kraine measured a very good black level and good shadow details. So, i think my settings must be much more imperfect than Kraines are. Unfortunately i don't have any calibration tools and can only work with movie scenes+test patterns, like Buroschs.
I Don't want to say you miss something but sometimes if the colour range of hdmi is not proper according to source can be a problem
I use in eco mode and I have very good black level and the best shadow detail mixed
I get best day scenes with other projector but not dark scenes
I my settings are film mode right out of the box
and hdmi colour :in limited range
So far this little guy is doing its job quite well as our day-to-day TV. I have it displaying a 94-inch image from roughly 11-feet. I use all standard modes, but would love to try Kraine's settings in our 1 user slot.
Also looking forward to Kraine's mini shootout between the K750, Optoma HD91, LG PF-80G, and Vivitek H9080FD. Not sure how the K750 will do against those other models (isn't the Vivitek $12k??), but it will be a good read and hopefully insightful on how best to set-up the Acer.
In any case, it will be the first comparison of its kind (that I know of).
The typical casino royal train scene and some patrons for black level and contrast .
I am using film mode by the fan mode and tweak settings in bluray but not too much in satellite receptor i can't touch nothing and still very good.
I am impatient too for the shoot-out of kraine will be very usefull if him can see this projectors at the same time.
not very good photographer a not very good camera
is a pity than change fan speed
Already the standard movie mode setting is ok for me, with screen colour set to grey or black. I prefer the very quiet projector above less colour error. So yes, all the K750 owners unite and ask Acer to change it :)
By the way, do you guys also hear this soft high pitched noise? I wonder if it comes from the phosphor wheel or if my projector has some issue.
I see to with select some colour temperature the light pumping in the brighter picture parts .
And change in bright when is selected the deep black control like brightness control with iris
but some pictures are a little bit burn as you can see down in amplifier display
casino royal train , vampire hunter and prometheus but the definition is good .
and dark mongoose scene
I am proud of the bourne legacy one
I take several classic of reviewers and some of stars to T-N-O
First about 2 weeks fan fail and off
and yesterday no warning and off
I try to put on and the warning lights goto flashing and all the warning light turn off and the remote don't work i have to unplug the projector wait several seconds and plug
then all work perfectly until the moment .
But was a little scare .
Right now is all is normal
the two times was connected to hdtv sat receiver (Digital+ ) never with samsung bluray dtv player is my other source
I should be call to the acer service?
