I apologize for the low quality photos. I do not own a digital camera, so these are from 35mm. They do not do justice to the severity of my problems with laserdisc and SVHS/VHS using the Zoom mode on my 47" Panny.


Here is the Dolby Digital startup from TRUE LIES. Colors are bleeding like mad and there is noise in the picture. The noise is much, much worse than pictured here.

This photo came out pretty good. The image is noise ridden, with jaggies along the wingspan (much more clear actual size, of course. This disc, which used artificial sharpening (like many LD's) is a shimmering city of jaggies.

Now this is an example of a crappy picture! On my 36" Wega, this looked pretty good. But on the 16x9 Panny, the image is bleeding everywhere, covered with noise and so blurred, that detail is lost. I just wish the jaggies showed on this photo.

Here we have HIGHLANDER, a grainy film that looks much better on Laserdisc than DVD. However, zooming in to fit the 1.85:1 ratio film to my 16x9 screen results in a digitized look, with loss in detail and much noise and bleeding. Lambert's face here is unnatural in color and riddled with noise. It looks much better Windowboxed on the set, as do all these LD's, but then I have gray bars on the side and black bars top and bottom! I'll burn my set up!

One last
PHOTO It's too big to post in the actual thread, so please click. You will see that detail is a joke, as the blurred image and mixing colors make the film look like VHS. There is no detail. Yet if I watch it Window-boxed, it looks great.


How do I improve the Zoom?! Can it be improved at all? Ltbx LD looks so painfully bad on my set, it's heartbreaking.


I'll post a picture of an AMC broadcast from Wed. night to show you how much better cable looks over LD. I'll scan and post the pic as soon as I can.


Ideas? I do know that SVM is one major culprit. It's making edges look jagged and giving lots of objects a black ring around them. It also enhances noise in the picture. What a terrific "feature."


9 point convergence is done and did improve things, but not enough. Sears comes out tomorrow to adjust gray scale and correct red push, as well as fix my white streaking problem. I ran out of film before I could shoot examples of that.


UPDATE: Here is the photo from the western on AMC. It wasn't exactly great looking, but it looked better than laserdisc, which is just crazy. Sides are cropped for file size.

Hey,

I had a Mitsubishi WT-46807. When I brought the set home, I set the SVM to 1 and did a 64 point convergance(user mode) on it. It has fantistic picture on all sources except for some old VHS recordings.


Perform you user convergance and adjust the color, tint, contrest, and bruightness controls. If after that you are not happy, take it back!

Matt,


Some of your pictures look like what my 56" Panny looked like out of the box.


Have you used Avia or VE to set it up? In the default mode, the Picture setting is maxed out, and Sharpness and Brightness are way up.


Once properly set up, Picture is down around 18, Brightness 23, Sharpness 7. (your settings will probably be a little different.) Your color looks very saturated also.


The 64 point convergence will tighten things up greatly, too.


After I got mine properly calibrated the picture looks fanatastic.


This may not be your problem, but it's a thought.

I should have been more detailed. I have spent all week adjusting this set. The first thing I did was take it out of Torch mode. Using Avia, I have a 25% Red Push and my Gray Scale is way off the chart. 6500k my ass. 9pt convergence helped a little, but not much. From what I am reading here and in HTF, this is what zoomed LD will look like on this set and there is nothing I can do about it.


But I need to fix my White Streak problem. It looks like this...

This problem is seen when objects appear on-screen that contrast sharply with the background. The DTS Trailer is a prime example. The BLUE in the logo will streak to the right. Blatantly obvious. There is a documented fix for it, but I with me luck... http://www.avsforum.com/ubb/frown.gif

Nice pictures--in spite of your comments. Just an overview opinion here. I don't find it surprising to read about your problems considering you're using laserdiscs and VHS tapes, then using the zoom mode. That's starting with fairly noisy, moderate or low-resolution sources, running the signals through a so-so(?) processor, than greatly enlarging them. Suggest you feed in a high-quality DVD signal, perform zero (if possible) zooming or other image manipulation and see what they look like. Try a known quality reference DVD such as The Matrix. If you find other comments or reviews questioning the performance of the video processor circuit in your set, you might want to consider trying computer image processing or buying one of the newer external scalers. -- John
