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 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?
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.
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.
