I see that there is a thread about the 3910 pq, but I have been doing the same experiments with the 1910 (actually mine is the 755s) on my HLP6163.


I used the Van Helsing DVD to do some comparisons and found that it looks alot better when using component (progressive with black level control off) over DVI (set to 720p or 1080i). Anyone else notice this?


On DVI, the darker scenes had a greenish-gray tint to the dark areas, but on components they were actually black.


On component, the colors were better, the black levels were MUCH improved and there was no mb. But the one drawback was that the picture is a bit grainier (not by much though).


Any advice on using DVI over component or vice versa?


I may post some pics tonite when I get home from work.

Really? Wow....I always thought that they DVI cable quality didn't matter. I will have to give that a try.

It probably means that the grayscale isn't set quite right in the DVI part of the TV than the component part. This can be corrected. Not usually an indicator of one signal type being better than another.

I calibrated them both with DVE. Is there something else that I should do? in the service menu maybe?

Calibrating with the test discs does not change grayscale (much) ... you need a color analyzer to fix the grayscale or a really good eye for what black and white is.


It would be fixed (somewhat inthe SM with the cuts and drivers /bias/gains)

Thanks Michael.


Does the quality of cable matter with DVI or HDMI?


I have both a DVI cable (came with samsung dvd player) and a DVI to HDMI (ordered from ebay for my HDMI input).

Interesting...I rented Van Helsing this weekend as well. Using the 720p upconversion to a Samsung HLP-6163 via DVI "with" a pretty expensive DVI monster cable. Black level is off on the 1910 as suggested by many. MB issues appeared w/ a dark purple color vs. black - not great. When I switched the Samsung to the Cinema setting (cinema/standard/dynamic), those issues mostly disappeared. However, I'd prefer to "brighten up" the picture a bit with many of these dark films - same problem with Underworld which has an incredible soundtrack by the way.....I'm going to try running a component cable vs. DVI. Unfortunately, the 1910 doesn't upconvert with component - may return the unit and just go with a good progressive scan unit.

I have a 1910 hooked up with DVI and Component (for 4x3 DVDs).


One thing that might help out with the DVI issue is to try going into the service menu and play with the Gamma setting. I have a HLN5065W and with DVE it looks best with the Gamma set to 1 on the DVI input.

ARP,


Will give this a try tonight. I recall seeing this adjustment in the set-up menu for the Samsung. Just curious, have you seen any difference with DVI vs. Component in terms of "dark scenes and MB issues" in movies with your HLN? Which picture setting do you generally use?

The only reason that I saw differences initially was because the Samsung DLP's hold video setting per input. If you adjust something for DVI, Component 1, 2 and 3 aren't effected.


Using Digital Video Essentials and a THX Optimizer, I have gotten the DVI and Components really close.


I use the Custom video setting as follows:


Contrast = 98

Brightness = 56

Sharpness = 25

Color = 52


Our sets are different so you may want to use DVE or THX optimizer to fine tune it.

The Faroudja chip inside your TV will not work in DVI mode. This might explain any differences as well.


When using the component input you will be using DCDI (unless you disable it) which could possibly bring out some differences in the grey scale.


Personally I prefer the DVI image because it looks crisp and vibrant without the hard edges of the DCDI processed component image.
