Any way to bridge the PQ gap between LCD and DLP?

780 Views 8 Replies 3 Participants Last post by  lousyreeds1
Hi,


After reading some great reviews of the Sharp PG-A10x, I bit the bullet and purchased one. I'm not particularly impressed with the picture quality on DVDs, coming through a progressive scan Denon DVD-1910 with the faroudja chip. I had a Benq 6100 and an Optoma H30 before this, both of which I had to return because of rainbows. But the picture was waaay better on both of those.


I know that the drop in picture quality is probably just inherent in the fact the the Sharp is LCD, but is there anything I can do, settings-wise, to improve the picture?


Thanks!

If you can return it do it. Otherwise you could sell it at a loss and get the Z3 or AE700. From the reviews coming in, they're both worth your money over simliar priced DLP products.
This may not help - but my Sharp looks much worse displaying component from my DVD player compared with outputting from a computer DVD player. Do you have a laptop with a DVD player you can test this out with (enabling color space profile)


I tried gray screens for a while and later on just went to plain matte white. The silver screen diy screen definitely helped with obtaining dark blacks - but nothing is going to change the 450 contrast ratio.


I really like this projector for high definition and DVD output at native XGA resolution. Can't you just be happy trading off the better detail for the lack of contrast until prices come down on other options and you've had some use of the Sharp?
I don't have the money for an AE700 or the Z3. Thanks for the advice, RalphArch. The biggest problem with the image is actually the graininess and pixelation, not a lack of contrast. I am happy with it. I'm just trying to get the most out of it that I can...
I don't know what you mean by graininess and pixelization - I don't have these problems at all - with my viewing sent to A10x by RGB 1024*768 out of computer for Desktop and DVDs and via component for COMCAST high definition STB (6208 @ 1080i). Are you referring to the sharpness of the individual pixels? In which case I would recommend a slight defocus if you care to smooth it out. ( I won't do this myself as I also use the Sharp as a computer display for my HTPC and I like the sharpness.


Another thing you could do is go with the Panamorph - I am a little leary recommending this to you considering some of the comments you can find on that thread; but it really does make the experience more filmlike, diminshes the screen door which I believe for me is not a big factor at 14 feet or so. But DVDs viewed full screen 1024*768 (out of MyHD card) and focused back down to 16*9 make screen door a real non-issue for me.


Then again if I had an extra $500 I agree with others I would scratch a little deeper and go with that new LCD (700?) with the true HD resolution and the better contrast ratio instead of a panamorgh


What is your viewing distance??

Hi there,


Thanks for the continued help! The AE700 is going to be a lot more than a $500 upgrade. It would be at least $1000 more, which is totally out of the question. Can you tell me a bit more about Panamorph? What is it exactly? A line doubler?


Maybe graininess wasn't the right word- I see a lot of "noise" in the picture. For instance, if there's a bit spot of a single color, I see the pixels moving around in that spot. Does that make any sense?


My viewing distance is about 17', on a 100" 4:3 screen high contrast grey screen.


Thanks!

To me that seems like classic screen door, beyond the distance where you can actually see the pixel structure you can seen this shimmering in areas of the screen of a single color/brightness. I notice this as well. You must have very good eyesight to see this at your viewing distance.


As I mentioned I think you can overcome this with a slight defocus - just go up to the screen after focusing as sharp as possible and back off just a tad where the pixels start not being quite as sharply defined.


The panamorgh is a lens which will take the full (resize a 16 by 9 dvd or HD show to 4x3 -I use MyHD card for my scaling) output at 1024x768 and focus it back down to 16x9 This totally eliminates screen door for me as well as smoothing the image from the sharpness. The lens also slightly increases light output and reduces light spill. See this thread for more info.


There were some initial problems with the lens - and currently some are happy and others not so pleased as perhaps the expectations were higher than what was realized.


Personally I am somewhere between the extremes with a lens that has an area of double image and am trying to see if I can get it looked at again, but am overall glad I purchased the panamorph.


However this lens would seem to be the ticket if what is really bothering you is residual screen door and you have an ability to output DVDs or HD material at 1024x768 (If all you are viewing is standard fare DVDs perhaps the Sharp and its XGA resolution really aren't any improvement over the SVGA projectors).

One thing I didn't ask and you didn't mention - hopefully you are using the vga/compnent input - not the S-video


If the latter was the case it would not have been fair to compare the Sharp with other projectors without taking advantage of the XGA resolution.
Hello again,


I decided to return the projector. After a bunch of tweaking in the menu, I just couldn't get it anywhere close. I'm beginning to think that the bulb might have been old and degraded. It was a demo model, and the company might have reset the lamp clock.


I was indeed using a VGA-component cable.


Thanks very much for your help, I really appreciate it!
