Rajiv,

My screen is 60 x 80" or 100" diagonal. All my video runs through my satellite receiver which outputs 1080i but cuts off some of the left and right sides to fit the 4 x 3 screen. I guess it's like 1440 x 1080i. The 4200 looks magnificient with HD video. Run that video through my gamma (shadow enhance) box and the blacks are black. Nice contrast ratio. The 4200 isn't a bad projector.

Of course it is not a bad PJ !!!

Scott, I moved my PJ a foot back. The image is sharper now. My screen is around 87" wide. The projected image is like 90 inches.

I suggest someday trying to pull back your PJ and see if the image becomes sharper.

Mine does.

Other people here have told me that the HD10 lenses do not throw a sharp picture on small screens.

Do you have HD10L lenses instead ?

I have used these rubber fan mounts and found them to be pretty nice.
You just pull them through the holes and they isolate the chasis from the fan a little bit.

IMHO it reduces the noise.

They were cheap, bought here:

These ones are meant for fans with closed corners....but when my fans arrived I discovered that they had open corners....nevertheless they work just fine.

Well this projector is so very nice but I eventually found out that it is not really suitable for my screen (only 87" wide) It performs its best at bigger image sizes like 100" or more. At those sizes it is extremely sharp and fully converged.

The small size of my room and huge door like speakers dont allow me to have a bigger screen

Maybe with HD10L lenses (instead of the stock HD10) it may perform better on such a small screen.

But I recently found a G70....

So what are you running these days?

I heard even people like Art moved on the digitals!

I told you a very long time ago to try a set of HD-10L's. You won't really see the straight 10's shine till you're up in the 120-140 inch range. You don't have to believe me. Just try this one time. set your green lens adjustments to dead center and slowly move the projector back until it focusses perfectly in the center. If your beam focus and astigmation are correct, you will see a ultra sharp image but will be way to big for your room. Before you waist all that time you have invested in this projector, find a set of 10L's and try it. It will be much cheaper than starting from scratch with a new projector.

Chip, is that 120-140 diagonal or 120-140 wide?

I have a 126" st130 that might look pretty good with that pj.

I'm not 100% sure because it was 4 years ago that I did that test. But I'm pretty sure it was "WIDE". I tried it on a 120 diag 4:3 screen first then had to pull it back further. I was unable to do the test at my house as I had no room big enough to do the test. I had to use a barn wall that was sheetrocked and painted white.

You are 100% right !

I have tested this too and found your claims are absolutely right. I am not sure about the 120" thing but my PJ was extremely sharp and fully converged at around 100" . I had no room to go bigger.

But alas, I was never able to find a set of HD10L lenses for a reasonable price.

Raj, wish I'd known you wanted a set. I've got one in my garage I'd sell ya for a good price, but I suppose you've moved on now.
