The source for your display can be your Blu-ray player, a game console (PS3, Xbox), an Over The Air (OTA) antenna, and cable/satellite box. The key to this is that you want your source to be able to match the resolution of your new display. If your display is capable of displaying a HD image, it would be worthwhile to invest in a Blu-ray player, a HD cable/satellite box or the proper OTA antenna that will get you an HD image.
Connection should be made using an HDMI cable for a HD display. This will provide you with the proper digital signal that your display expects. A lot of satellite and cable boxes will only come with the older analog cables (Red, Green and Blue). It would be worthwhile to invest in an HDMI cable - at least for satellite. HDMI cable can be quite expensive at local stores so you may want to look into purchasing one from one of the various online retailers who sell them at a significant savings - Monoprice, Newegg, etc.
For cable and FIOS boxes we recommend using the analog component video RGB cables to avoid the HDCP (Hollywood copy protection) as the HDCP slows down the channel changing and may cause other errors and sometimes sparkles in the video. Analog component video is less prone to signal problems and delivers the exact same video performance. Something to keep in mind is that older cable boxes and such had issues with HDCP. That is why we recommend the component cables. Newer boxes may be able to handle HDCP/handshake problems better and should be utilized. It's also important to note that without HDMI, you cannot get 1080P or 3D if your box supports that.
New displays are capable of 1080p, 1080i, and 720p resolutions. For your source output, we would recommend setting all cable, FIOS, all satellite boxes and BD players to "Native output" and let your TV and or audio receiver do all scaling. The reason is the cable/FIOS/Satellite boxes have very low cost (low quality) internal video processing, whereas most audio receivers and TVs have better video processing.
The aspect ratio of newer displays is 16:9. This can sometimes be labeled as HD in some menu systems. You want the image to be displayed properly therefore some ratios such as zoom and full may need to be avoided.
Picture Presets or Picture Modes
Today's displays contain various preset picture modes. They usually include something along the lines of Dynamic/Vivid, Standard, User and Cinema/Movie. Higher end displays will also have a THX and/or an ISF setting(s).
The Dynamic setting is generally a higher brightness, contrast and sharpness mode which, in my experience, results in an overall bluish look to the image. This is usually a setting that would be favored by video games and rooms with a lot of ambient lighting.
Standard setting will have a little less brightness and contrast than Dynamic.
Cinema/Movie mode would have brightness, contrast and sharpness set to a more realistic value for a more realistic look. This would probably be the closest mode to the Rec. 709 standards.
User mode would be a mode that can be changed, either through calibration with a meter or by eye, and then sometimes named by the end user as their preferred mode.
THX mode - from THX's web site:
What Does It Mean To Be THX Certified?
It means each TV and projector has gone through a rigorous design and laboratory testing process, which includes more than 400 data points to ensure exceptional image quality and signal processing performance in your home theater.
What Are The Key Benefits Of THX Certification?
Exclusive THX Movie Mode: Comes as close as possible to reproducing the HD Color Standard used by filmmakers in the studio with THX Movie Mode.
Smooth motion for every type of content: THX certification improves de-interlacing and scaling performance, ensuring smooth motion for action-oriented content.
Optimized video scaling: Presents all content in the best resolution possible, including standard definition video.
Color, Black Levels And Beyond In Your Home Theater
Sports fans and home theater junkies often complain of jaggy lines and image softening when a TV’s motion becomes too intense. THX works closely with manufacturers to minimize these types of distracting artifacts, letting you experience clean, smooth motion and vivid colors with every frame.
Picture Controls - Display Adjustment
There are a myriad of settings within new display's menu settings. The general consensus among video enthusiasts is that any specialty functions such as Auto Black, Expanded Black, Black Corrector, Automatic Contrast, Dynamic Contrast, Dynamic Range, Auto Color, ACL, Auto Flesh Tone, etc. be shut off unless you really think it will improve your overall picture. Keep in mind that in doing so it will counteract any image fidelity you hope to achieve. The controls that can and should be adjusted are Brightness, Contrast, Color, Tint, and Sharpness. Some LCD/LED panels also contain an adjustment call Backlight. This will be discussed at the end of this section. Source material for adjustments include the THX Optimizer (included on several retail discs), Spears & Munsil HD Benchmark, Disney's World of Wonder (WoW), DVE HD Basics and Get Gray.
Contrary to what most people think, brightness actually controls the black levels of your display. This should be adjusted using one of the calibration discs or the THX Optimizer available on many dvd/blu-ray discs already released. Most discs have this labeled as 'Brightness'. Spears & Munsil has it labeled 'PLUGE Low'. PLUGE stands for Picture Line-Up Generation Equipment. Here's how the various brightness patterns look.

Here's what the pattern will look like when brightness is set too high:
Brightness should be set in the above image so that the 0% (16) bar blends in with the background. This should make the two bars to the left disappear and the bar to the right (1%) should be barely visible.

Contrast is the white level setting. On some sets (Sony for instance) this can also be labeled as Picture. Michael Chen (michael tlv), an instructor for both THX and ISF video calibration courses, puts three rules to calibrating your white levels - no clipping, no discoloration, and no eye fatigue. Clipping occurs when you're contrast is set too high causing white levels in the upper area to blend in with those that are of a lower value. For instance, 229-235 white all blend in with 228 white. Discoloration occurs when you see any hint of color (usually pink) within the upper white levels. This is generally caused by contrast being set too high. The third rule is no eye fatigue. Eye fatigue should be checked with a 100% white window box image. If viewing that image causes fatigue (do you think it's too bright or that it hurts your eyes), your contrast is set too high. This can also be set using a meter. The general rule of thumb for this is to set it from 35-50fL. This can be display dependent in that a front projection system should be set from 12-16fL while an LED/LCD can be around 50fL. It's also important to note that this is user dependent as well. If 35fL is causing you eye strain, turn the contrast down until it's at a more comfortable value.
The pattern for Contrast will look like this on the various discs:

Color - This can sometimes be labeled 'Saturation'. Adjustments by eye alone can be difficult but what you would look for are over saturated skin tones (red faces) or cartoon type color image. If you have no calibration disc with the blue filter, your best option would be to set your display to it's Cinema, Movie, or THX mode and leave well enough alone. Some sets will have something called 'Blue Only' mode. This would replace the blue filter and allow you to adjust color and tint properly with a SMPTE color bar pattern displayed. With the blue filter and the color bar pattern, you want to adjust color until the blue and white bar match each other while looking through the blue filter.
Tint - This can also be labeled as 'Hue'. Tint is pretty much the same as color - if you don't have a meter or a disc, leave it alone. To adjust it with a disc you will need either the blue filter or a 'Blue Only' mode on your display. With the blue filter and the color bar pattern, you want to adjust tint until the cyan and magenta bar match each other while looking through the blue filter.

After setting color and tint you'll want to check out your settings by using an image that contains human flesh tones in it. DVE HD Basics has a video sequence with a restaurant scene:

Also known as artificial edge enhancement, sharpness should be set as low as possible. Set too high, sharpness can cause something called the halo effect. One of the better ways to check for this is to use a scene with the edge of a building in it. You will usually see a ghost line next to the edge of the building. Using the patterns on the calibration discs, when sharpness is set too high you will see a glowing (white) line or a halo next to the black lines. Set too high, sharpness actually results in less detail on your display. The procedure for setting sharpness using the patterns that follow is to set sharpness to a high setting that results in the haloing effect. Then turn it down until the halo/white glow goes away.

Gamma is probably best explained at this Wikipedia page. Recommended gamma values for your display vary from 2.2-2.5 depending upon your environment's variables. Gamma cannot be adjusted by eye. It requires a meter to read the luminance of grayscale images.
There is a Gamma image on the Disney WoW disc:
I have yet to test out the above image to see if it does match up with my meter readings. When I do I will let you know
Backlight is a value inherent to LCD/LED display technology. Normally this setting would be very high OOTB (Out Of The Box). Reducing it will alleviate both eyestrain and your electric bill. My Sony's backlight is set to 0.
You'll want to avoid glare and/or reflections from either daylight or room lighting. If possible, place the display in an area that will be affected the least by these issues. Use blackout curtains or shades if reflection from daylight is bothersome to you. It's also important to remember not to view your display in a totally dark environment. That is not good for your eyes. If you want to have the room as dark as possible, we suggest investing in a back light for your display.
