Problem with my HD1000?

post #1 of 10
Thread Starter 
I picked up a mitsu HD1000U and for the price it's a fantastic product.

This is my first DLP projector in a post-CRT world. The CRTs produced a fantastic image, but the whole convergence thing got really old after a while. This is why I'm pretty unhappy that I can't see to get the pixels really crisp on my mitsu HD1000U.

normally I'm not a "pixel peeper" or "measurebator" but I couldn't help but notice that when I display the test cross hatch pattern from the internal menu I can't get nice clean pixels!

What I'm seeing is something much like the old CRTs when they get slightly out of convergence - something resembling a white line with identifiable pixels but then a noticeable amount of blue and green (I think, I'm colorblind) on either side of the lines (nearly as wide as the pixels themselves). The white pixels themselves are not very sharp, either.

I have it in ceiling mount mode about 14 ft from the screen (ok, my wall at this point). No major deviations from factory defaults have been done to the projector (including keystone). I have it set to the smallest image possible (though I notice the same effect at larger sizes). I've had someone stand at the screen with me up a ladder to see how close I could get it with the focus ring, but still I can't get it very sharp. I've let the unit warm up for an hour with no noticeable change.

It's worth noting that when showing images like movies it still looks fantastic and you have to get up against the wall to really nice this effect, but it's there for sure. When watching movies the pixels look sharper (up close) and there is more noticeable Screen Door Effect in this mode (720p component input) then when driving straight from the internal menu.

is this normal? should I care? is it just refaction through the lens noticeable at this distance?

From the seated position it still looks very good and it probably wouldn't bother me except that I thought I left all this behind when I got rid of the CRT ...

I can take photos if that would help.

thanks in advance

Will

I don't have the HD1000u yet - its supposed to be here tomorrow - but have you checked the overscan setting? Make sure its set to 100% so there is no scaling. The overscan may have no effect on the internal test image but its worth checking.

I agree it could be the overscan. The mits is set to 97% from the factory which can add softness. Set it to 100%

A review of the similarly lensed HC1100 and HC3100 at www.cine4home.de showed some visable chromatic aberation ... so yes I would say this is probably "normal" for the HD1000 (he said without seeing a picture of the problem.)

your (and KillRob's) suggestion of setting overscan to 100% certainly did help! It was set at 97% per factory settings.

Why would the factory set it to 97% to begin with when clearly 100% looks much better?

Are there any other "must change from factory default" settings I should be aware of?

Besides the overscan setting, my unit came with Brilliant Color set to three, which I changed back to zero, and I also put lamp into the low mode to lengthen its life

I've read that Setup should be changed from Auto to Off to make sure you get the full range of blacks at the low end.

Also read that if you want to turn off all digital edge enhancement set Sharpness to -2 and not just to 0.

My overscan setting is 97% but grayed out (not changeable) via HDMI and component. How do you change the overscan to 100%?

Huey, set the aspect ratio to 16x9 which will allow you to adjust overscan to 100%. Now, put aspect back to real and your set.

OK, that make sense. Thanks.
