If so, may I ask why?
one of the reasons Tom just mentioned. Better contrast. The spec is 3000:1 but that must be on/off contrast. So the contrast after calibration may be less. Dont know how less it will be.
Shorter throw (1.77 vs 1.64)
DVI .4805 has M1-DA so you need that adapter which is $45 or buy the
M1-DVI cable which is $99. For $45 I can get a decent DVI cable from parts express or better yet use the DVI-I cable that came with my DELL PC.
M1-DVI adapter or cable is not something you can get from the net. only infocus sells them and you are forced to buy that at ridiculously high price.
lower fan noise and shorter throw ratio works out well for me
as I have to table mount the PJ. It can get farther from me ans still
give the same size image as 4805 and will also be quieter. Even if all
other aspects are same I will be sold on these two.
More aspect ration options. Tom had mentioned that the image
can be moved all the way up so that there is no bar at the top for 2.35
So making DIY masking may be easier as I have to deal with masking only one side.
I was hoping H31 will have less light spill but looks like it has a lot of light spill.
I am not sure about customer service by optoma. I am able to easily reach Infocus support.
My main reason to change is not picture quality but other reasons. The black level on 4805 is very good and it will be hard to beat it by a significant margin. So I am hoping the non PQ related differences will be better on H31. Someone has to do a shootout (not just image comparison)
PS: If anyone does a shootout please look at all the non PQ related issues also. I am sure both the units will be very close in image quality. Most or all shootouts dont care about other issues. No one ever said that fan is loud on 4805 in the shootout. Only when you get it to your place you will see all such issues. Moreover what is loud to one is not the same to others. But looking at the number of people complaining about fan noise on 4805 and also 5700 and 7200 I guess fan noise is an issue and has always been an issue with Infocus products starting from X1.
If 4805 had a quieter fan I wouldnt bother to replace it until it died
because the PQ is just incredible after all the things I did to my room and screen. Just couldnt stand the fan.
