I just bought some HD10L lenses. Will these be any better than the HD10-GT17 lenses on my 1209s? My screen is 85" horizontally and I was thinking that these lenses would be closer to the center of their focus range at that width. Does this make sense or did I just waste my money?

Oof. I think that's too wide a screen for the 10L's, I think they're spec'd for somewhere in the 75" range IIRC. I ran my 10L's on a 67" wide screen and they were great for that.

I think they'll be fine, MP 's screen is not much larger and he uses the 10L's .

So Kruger you got those for 57 +45 shipping not bad!!! I was looking at them but forgot, i was going to test all the different HD 10's I have for the blend to see which focus best at the edges. I have almost one set of each type !!

I'm close enough to pick them up myself so no shipping charges. Only $57.00!

For $57 you might as well try them out, not much to lose!

I am finding this new found love of the 10Ls kind of funny. It seems not to long ago that people were bitching and complaining that a lot of the Marquees came with the 10Ls. Now, they might be as valuable as gold. Smile

I don't think they can resolve as well as the GT-17's. Only 10 lines vs 12 lines for the 17's.

I have HD-10L's on my 9500LC shooting on a 83" wide Draper screen (79" surface). I'm not seeing any problems at all.

Now, it's been known for a long time that there was a problem with the HD-10L's on the right side about 1' inwards from the edge.

Then it was mentioned that that same problem was not on every set of HD-10L's, only an earlier version of the lens.

When we had the problem with the HD-10's the solution was simple, we upgraded to GT-17's. And that was only when the HD-10L's were used on larger screens.

Gary M. is having a problem with his HD-10L's that's puzzling me, because I have almost the same width screen and things are flawless here.

Is there some way to tell which lenses have the problems?

[quote="stefuel"

Put up a low rez (480P) image. Look for scan lines on the tube face. Should be big honkin scan lines. Try to focus those straight 10's on those scan lines. That will quickly show you how poorly straight 10's perform on small screens.
I experimented with these lenses 4-5 years ago when I was having problems focusing on a 120 inch 4:3 screen. I was unable to see scan lines at 960P on screen when they were clearly viewed on the tube face. The projector had not been mounted yet and was still on a cart. I found that when setting the lens adjustments to exact center points that I had to pull the projector back quite a bit before the scan lines showed on screen. I estimated that to be about a 130+ diagonal 4:3 screen.
You will not get any better performance from GT-17's trying to use them on a screen size that 10L's are optimized for.

Blending seems to be the big rave now. I never will but if I were to and I was considering a 100" wide screen, I would not think twice about using 10L's for it and would suggest GT-17's for a blended 140-160 inch screen[/quote]

Yep. That screen with those HD-10´s i now have. I can barely see interlace fields with 1080i Laughing

I have source to those HD-10L:s, havent picked up those yet..

Pick up those 10L's and you'll think you died and went to heaven. Wink

Isn't this kinda what I was talking about here?

I have GT-17 Lenses. Not that I'm going to replace them, but isn't there a correlation?

Just trying to connect the theories.
