Model: Samsung LN46C750 LCD TV
Description: 1920 X 1080 46" LCD 3D Compatible Television
This is not HD. It's a beautifully unconverted shot from the a 480i DVD of Jaws.
The C750 series packs a strong punch with the new 3D TV compatibility feature combined with some of Samsung's best features from the past. Samsung isn't only producing LED backlit LCDs for 2010, the C750 line of CFL backlit LCDs contains many of the features of the more expensive LED TVs at a more affordable price. The C750 uses Samsung's 1080p, 240Hz "Ultra Clear" panel. While we found the motion blur reduction of the AutoMotion Plus 240Hz and 120Hz impressive during sports programming we didn't like the effect it had on picture depth in film programming. Other high hertz rate TVs didn't showcase this issue so we are hopeful that this has been remedied for 2010.

The CFL backlight on this TV is very strong and provides plenty of brightness. It's relatively easy to adjust the backlight for varying room conditions. By using the Movie setting, you are essentially deactivating the inbuilt new Eco Sensor feature. So we feel it's better to adjust the backlight on your own via the 20 point scale. This LCD TV has a tremendous CFL backlight. We needed only set the backlight at 7 from the 1 – 20 scale to achieve a desirable picture in a darkly lit room.
Processor Testing: The internal processing chip sets for the C750 series LCDs are very good. One of the first things we noticed during testing was hose crisp and clean edges were without adding unwanted edge enhancement artifacts. The Sharpness control should be kept low between 10 and 20. Using it at a higher level with produce nasty edge glow artifacts.
3D TV Viewing: We were able to view this TV with DirecTV 3D content at CES 2010 in a special viewing area using the provided 3D glasses. We noticed a strong eye strain when the scenes changed from frame to frame. The DirecTV content was not smooth or enjoyable to watch. As we have pointed out in many articles, the viewer will not see 1080p HD through both eyes in LCD TVs due to limitations in Hz the rate. I do not think this had anything to do with the eye strain we encountered. We believe that resulted from the rough up programming shown in a hurry at CES.
This shot from Jaws shows just how good the TVs upconversion from 480i DVD is. Notice the crisp details in the jacket (anchors).
Up conversion from 480i and 480p: In the past we have harped on the importance of the AutoMotion Plus 240Hz or 120Hz technology contained in this and most all of Samsung's LCD and LED TV offerings. The importance of the performance of this feature past and present cannot be overstated. In the 2009 series B750 series we recommended turning off the 240Hz feature for all but sports programming due to the unpleasant side effects produced when the feature eliminates the natural background blur of the picture. We believe the feature is much better this year albeit still intrusive for some viewing. Our recommendation is to follow a Custom setting for this feature of Motion Blur 10 and Judder Reduction 2 when viewing 480i DVD and normal non-HD broadcast content. This will eliminate a lot of motion blur while not introducing an artificial looking picture which reminds you of a soap opera. See our instruction below under the Features section about how to get to this feature setting.
Another good detail shot from Jaws.
With this modification, I enjoyed the picture presentation on the C750 very much even with 480i or broadcast content. The Ultra Clear screen panel produces a magnifying effect brings scenes to life. Images are crisp, black levels remain very rich, and color is impressive. There is very good light flow through the picture which allows for lots of detail even in dark scenes. Surprisingly, side viewing are solid even with 480i content without degradation of blacks and contrast.
720p/1080i/1080p Picture Quality: Black levels and contrast are very pronounced on this TV. Images are crisp and the detail is amazing with HD sources. The big decision is whether or not to engage the 240Hz Automotion feature or leave it off. It does introduce some unrealistic effects. My recommendation is to either leave it off entirely (except for sports programming) and get used to some judder and motion blur, or use the custom setting mentioned above.
Contrast, color, and dark shadow detail; this shot from the HD Blu Ray version of Master and Commander.
After tuning the 240Hz feature, high definition content appears vibrant, realistic and extremely crisp. Blacks are rich for an LCD and contrast is a strength. One of the strength features of the LN46C750 is the unusual amount of displayed depth for an LCD TV. The aforementioned Ultra Clear panel has most to do with this. Colors are very rich but not oversaturated.
Black Level/Contrast/Contrast Ratio: Black Levels on the C750 series LCD 3D TV is super saturated, as black as the glossy black bezel surrounding the screen. We believe contrast is also enhanced by the Ultra Clear Panel that Samsung uses for this LCD TV. Contrast is very impressive on this TV even compared to plasma TVs.
Dark Shadow Detail: Though black levels are excellent we thought shadow detail was still good with most material due to the TVs very bright backlight capability.
Roy's House in 480i DVD of Jaws. Great color and contrast.
Color Rendition/Color Accuracy: Colors are bright, rich and vibrant but not oversaturated. The color rendition of this TV is exceptional.
Viewing Angle/Off Axis Viewing: There is negligible to no degradation of contrast and black levels at angles even 35 degrees off center. An exceptional result for an LCD TV with a CFL backlight. Samsung has the only CFL backlit TVs in the market with this quality.
Picture Glare: The more anti glare technology a TV contains, the less depth appearance with the picture images (and also hazy blacks and poor side angle contrast). Though the C650 does contain some effective anti glare technology, it does not interfere with the depth and beauty of the images. There is some glare though, so be prepared for that. To us the best scenario is a little anti glare technology and lots of picture depth and rich blacks. The C650 does just that.
Motion Lag: There is much less motion blur and judder effect with the C650 than with past models. With 480i content it is still prominently there with the 120Hz feature turned off, but with the HD content it's negligible even with the feature off.
False Contouring/ Mapping: We noted slight mapping effects in some dark content, but it was not a significant down point.
