View Full Version : Unexpected change...

I've been farting around with my Denon 2910/Samsung HLS5086 setup lately, and found something kind of interesting. I've been running my Denon in progressive mode to the TV via component, but last night decided to let the Sammy do the progressive/pull down. After switching the output of the Denon to interlaced and putting the Sammy in "film" mode, I had to recalibrate brightness/contrast; I thought was strange that simply changing the Denon from progressive to interlace would change the brightness/contrast level. I had to go 6 points higher on brightness, 4 points on contrast.

Anywho, FWIW I think the Samsung does a slightly better job in progressive mode, albeit subtle.

On the flip-side, I noticed using HDMI out from the Denon increased brightness to the point of needing recalibration.

What are the internal settings of the Denon player at? Some players have their own user settings.

Having to recalibrate a bit when going from progressive to interlaced is normal.

Chances are though ... that the Denon does the 480p better than the Samsung TV.

I haven't made any picture adjustments on the Denon---all at default values.

That's what I thought too, but surprisingly the picture seems a little better with the Samsung doing the processing, especially shadow detail.

did you calibrate the TV the first go around? Did you recalibrate again?

Hey Michael, would you think the Denon would also do a better job than my Sony 55xs955?

Thanks!

Best way to check is to use the HQV DVD benchmark disc for deinterlacing tests. Against the Denons ... you rarely find the TV processing outperforming it. (unless it is a Runco)

Please note though that the default output from most of the Denon dvd players I have encountered is slightly degraded. The contrast in the user memory needs to be set a few clicks down or else it outputs a white crushed image to the TV.

(If you send 95% of the signal to the TV ... it doesn't matter how good the TV is ... it will never be able to show 100% of the signal.)

Thanks Michael. Unfortunately i do not have a copy of the HQV disc, but i will try changing my Denon to progressive tonight & also check for white crush. I guess I will let my eye be the deciding factor here.

Thanks again.

Another white crush check ... from 5th Element.

The scene near the end when the waiter guy enters the room full of the creatures and says "Show time" ...

Pause on the white jacket ... and play with the denon contrast setting and see what happens to his jacket. A few clicks down should squeeze more detail out of the jacket.

Yes, both times with DVE. That's how I noticed the change in brightness/contrast levels.

denon progressive: Contrast 34/Bright 44
samsung progressive: Contrast 38/Bright 50

both via component and calibrated w/DVE.

Thanks Michael, I'll have to check this out. I'm really pleased with the DVD playback on the HLS5086W---it's far better than I had imagined it would be.

My settings for DVD on the HLS:

Method: DVE
Input: 480i from denon 2910 via component
Contrast: 38
Bright: 50
Sharpness: 25
Color: 30
Tint: G45/R55
"Film"
Color temp: Normal
DNR: off
DNiE: off

Hey Michael, just tried sending my Sony a progressive signal via component out from my Denon 2910 but i'm experiencing a lot of "jaggies". Picture does not look that smooth at all. Any recommendations?

Thanks again.
Carmine.

Make sure the 480p section is not set to VIDEO in the DVD player.

Anything weird from the TV end ...>?

Ok. I just checked & it is set to AUTO on the Denon. My Sony 55XS955 settings become grayed out when selecting progressive on the Denon.

The theory is that the Denon does it better ... but if you are finding differently ... that's okay too. At least now you know. Keep an eye on the user presets when you go back to 480i ... inthe Denon.

I actually ended up going to an HDMI cable and recalibrating. I'm very pleased with the results---gone is the "glow" around Marlin in "Finding Nemo" and the slightly off picture centering via component. I'm running the Denon 2910 at 720p, letting it do the processing. I still find that the Samsung seems to do a little better with shadow detail, but this is small potatos compared to the problems corrected by going HDMI. Watched "Barnyard" last night--it was incredible.

Thanks all. HL-S5086W settings now:

Contrast: 28
Bright: 42
Sharpness: 25
Color: 28 (adjusted by eye, DVE showed 44--way too vivid)
Tint: 50/50
DNR: off
DNiE: off
Film: off
Temp: Normal
