Hey everyone....I recently got a Samsung A32A330 32" 720P TV, a Rogers HD Cable Box and a Sharp Aquos BDHP21U Blu ray player.


The HD cable and the blu ray movies look amazing, the colours are rich and there is no slowdown or synch problems.


However I am having one major annoying problem. Certain things on screen flicker or shine. It's really hard to explain, but a few examples include:


-In House of 1000 corpses, a guy is wearing a black and white stripped shirt and the shirt flickers a lot


-In The Dark Knight a lot of the imax panning shots of the city, the sides of the buildings flicker


-When watching Spiderman 3, there is a scene where a guy holds up a basketball, and the lines on the basketball shimmer or flicker


-When watching an HD version of UFC Unleashed, the cage itself flickers a lot


I have searched this quite a bit, and someone mentioned something about an "Auto Contrast" setting in my TV being the problem? I looked through both the user menu and even the service menu and couldn't really locate anything that resembles this.


Someone also suggested turning ON movie or film mode, and turning off image filtering, which I did.


I also tried 720P and 1080i modes, both do the same thing.




Has anyone experienced this? Is there a solution?


Thank you all for the help.

yea i noticed that as well with Batman: the dark night....right at the beginning when they pan through the city...i think it happens only with multiple fine lines together. i watched it on the parents sharp 52d82u...im gonna try it on my plasma with a different blu-ray player and see if the problem persists, then i might be able to give a better judgement as to why it is happening

well i did a little researching and this effect is called the Moire Effect....possible causes are either your blu-ray player, and/or your tv...if you have any enhancements on; on your tv that may be the cause as well

well found out a little more info....seems that when you have a interlaced signal being output either through your blu-ray player or through your cable say like 1080i it has a problem doing so since all lcds/plasmas are natively a progressive tv. so either the source or the tv has to deinterlace the source so it becomes a progressive image such as 720p or 1080p to match the tv's natural definition. In doing so this can cause the moire effect becuase the tv/player is altering the image ....well so far thats all i got.....try to see if it happens on you tv only when its displaying a 1080i image...

Thanks for the update Memphis, however, I tried both outputting at 720P and 1080i with no difference

All of that happens when the sharpness is set too high. The sharpness simply enhances edges, and if done excessively there are halos around the edges. If you have alot of edges nearby each other (example windows on a skyscraper) the halos bump right into each other and as they wax and wane it creates a shimmering effect.


If you simply switch to cinema mode the sharpness should be low enough that it stops happening, also turn off edge enhancement if you have it as an extra feature.


The usual rule of thumb is set sharpness to 1/3 the max, but if you have a calibration disc or even a thx certified dvd you can more carefully set the sharpness.

I agree with the above. Also remember that some DVD players have an edge enhancement setting and/or sharpness setting. So you can get a cumulative effect. If it is turned on in the player and in your tv set, it can be way too much.

Yeah my Sony player (700H?) adds un-defeatable edge enhancement and it's terrible! I hate when dvd players add "features" that you can't turn off.


And not only that but when the dvd itself has edge enhancement the result can be a disaster (I'm looking at you Phantom Menace!).
