Can anyone shed some light on the Toshiba's *HDX82 picture being so dark? The biggest complaint I have heard from these sets (including myself) is the Picture losing shadow detail.

I guess this is mostly corrected after a calibration, but what was Toshiba thinking? My understanding is the H82 line is not experiencing this.

Is there a benefit that I am missing? Did Toshiba get a good price on lower quality CRTs?

What can be done to combat this issue?

I have a 57HDX82. With most DVD movies the picture is nice and sharp. Brightness is about what it should be. The other day I put in Jurrasic Park 3 and the picture was so dark I could hardly see anything. I thought maybe something went haywire with my TV so I put Spider-man back in and it was okay. Put JP3 back in and it was so dark I could not see anything again. I don't remember JP3 being that dark so I tried it on another TV and it was okay. Something about that movie does not like my setup. My Toshiba is calibrated with AVIA. I have a Toshiba SD-K710 (Costco's version of the SD-3800) DVD player. I am not sure if it is with the DVD player or something to do with the TV. I would sure like to know what is causing it and how to fix it. Thought about buying an RP-82 DVD player thinking it might be the problem.

The HDX82's do indeed have a very dark 'Movie' mode out of the box. After calibration, you end up at about Contrast 60 and Brightness 60-70. Dark shadow detail can also be affected by your grey scale.

So the question is why?

And if you make those types of changes during calibration (60 contrast, 60-70 brightness) are you tasking the television too much?

Greyscale is off on the Toshiba possibly - seek an ISF specialist! Mine is slightly dark as well. Going to get an ISf someday, right now I want an SVS subwoofer more.
Contrast should be about 45, brightness can be anywhere you want it (if you don't run calibration that is). Mine ended up at 54. I've heard of people at 60+ though. Contrast is the killer.

Yeah, I suspect gray scale would be off... But I think this goes beyond gray scale.

I am curious to why these sets are darker in general? Of course I only have seen one, my own... But every complaint I have seen on these sets all centers around darkness...

Does anyone have one of these sets that does NOT appear dark compared to another set, say Hitachi or Mitsubishi?

Greetings

If you set up the tV to AVIA or VE to where you are supposed to set it, then that is pretty much what the uncalibrated (Professionally) image is supposed to look like.

Other than the film setting (too dark) I have found the T.V. a little bright. I set contrast at 40.

Each set can be different, but in general, I've measured the HDX's in Movie mode at about 9-10 foot lamberts of light output in a 100 IRE Window test pattern. Most calibrators set maximum output to 16-18 foot lamberts (which, I believe, is the THX spec). In contrast to the HDX82's, a 42H82 measures in the 28+ ft. lambert range in Movie mode and last year's HX81 models were generally in the mid-20's

I would consider 16 foot lamberts as a perfectly 'safe' level for a projection set. Why is it set so low from the factory? Who knows...perhaps for the same reason (none) that the Brightness is set so obvoiusly high on the 42H82.

Thanks JohnnyG,

So basically we are saying that the fact that the HDX's are low is not either good or bad, it is just matter of fact.

It is not that they are not capable of producing a bright picture, they are just being set this way from the factory. Correct?

And you are saying a contrast level of approximately 60 considering sub-contrast has not been changed will produce approximately 16-18 foot lamberts... Right?

So... With that in mind, Hitachi's must be inherently set high, they produce a very bright picture ootb even at lower contrast levels. Hitachi's also are know for showing every flaw in every picture which is exactly what happens when you turn the contrast up on a Toshiba HDX model.
