Colour fidelity and fan noise issues (H5380DB)

bladteth

I have just bought Acer H5380BD projector to replace failing 5-year old Optoma. The problems I see with the new projector:

 

1. Colours are off, the picture is quite warm (yellow tint) and needs lots of tinkering with settings to bring it back to a resonable level. The contrast is not great and blacks look washed out, particulary in 3D mode (with glasses on).

 

2. The fan seems to be on the loud side and it changes speed every few seconds which is somewhat annoying. I can also hear spinning colour wheel - it was inaudible in old Optoma.

 

3. There seems to be uneven sharpness across the screen. While the centre looks great, the edges and particularly the corners are soft. A sign of poor optical element. Is this fixable withour returning the projector?

 

Thanks,
