umr, f300v10 & applejackaz:
Thank you all for the lighting suggestions. Light from the hall (which I would usually have off with my replaced CRT-set) works wonders with 'dark' movies like V for Vendetta. Now I just need to start looking for something that I can place into the room itself, possibly with a dimmer. I have a ceiling fan light that I can dim using a remote but it doesn't get dark enough and competes with the screen.
Also, thanks for the photo applejackaz.
If you get a chance to calibrate a 5679, please let everyone know how it turns out. If you see potential, I will get my set professionally calibrated too. I agree that movie mode (with slight tweaking for preference) is very close to 'right on' without calibration and more so than any of the other modes. Don't get me wrong, experimenting with DNIe settings has shown me its power and potential but it has turned out not to be a major selling point for me in any way when it's all said and done.
As far as the black level (internal ambient light, what ever to call it) it only needs to go down a perceived tiny bit to my eyes.
klac & all:
There is no black level problem. Contrast, brightness and colors are great. I just wish the black level was lower and closer to what my replaced CRT-based RPTV was. This is especially true for movies like The Crow, Sin City, Dark City, etc.
luidoly & all:
I have seen color banding on HD and SD channels of my H20 DirecTV receiver with DNIe on and the other picture modes besides Movie. It appeared usually in darker areas or in the backgrounds of shots. People and objects were fine. Bright scenes didn't seem to have it. Many Discovery HD channel programs didn't seem to have it as long as they were bright.
Also keep in mind that some color banding in some DVDs with subtle color gradients like Ultraviolet were there on my CRT RPTV as well (maybe because of the DVD or 10-bit processing, I don't know myself). The 5679 with DNIe ON or in other Picture modes besides Movie took those slight color gradients (with 'exceptablely' slight color banding) and exaggerated them into an extreme form of color banding.
As far as Red push, I haven't seen it. The colors look great to me and I've never had a concern about them at all from what I've seen from HDMI, component, over the air and cable (NOTE: there is a mountain of color options in the Service Menu that a professional can tweak to no end). This TV looks better than my replaced CRT RPTV and I now have HDMI inputs, Firewire, OTA and QAM tuners, etc. that I didn't have before in my main viewing area. Oh and I can't forget: no more convergence (finally) or burn-in (thank you).
I'm loving this TV. The family and I watched RV together moments ago and everyone loved the movie and the amazing picture quality (480p DVD - not the Samsung 960 I mentioned above; Component Video), especially the scenic view of the parks in it. Sure, I may have cringed once or twice in some dark night scenes but the picture and color were amazing.
Crutchfield as a wonderful return policy but this is the only type of set currently out that I want and I want this one. It's a keeper.
