How to Setup your TV, HDTV, Plasma, LCD (Video Display)

Learn How to Setup your TV, HDTV, Plasma TV, LCD TV or any type of Video Display for your Home Theater System.

Source

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

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.

Aspect Ratio/Resolution

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:

Quote:
In the studio, every shadow, color and detail is carefully adjusted to deliver the right mood and impact. Only THX Certified plasmas, LCDs and projectors, featuring THX Movie Mode, let you recreate this experience at home with the push of a button.

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.
While the THX mode is calibrated at the factory, the environment where this is done is probably very different from your environment. At a minimum, we'd recommend white/black level calibration using one of the discs mentioned in this thread.

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.


Brightness

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

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:

Get Gray:



Spears & Munsil:



Disney WoW:



DVE HD Basics:




SpectraCal videos on Contrast





Color/Tint

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:



Color set too high:

Sharpness

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

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

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.


Room Considerations

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.

Re: How to set up your display properly

Your compilation of helpful tips, graphics, and links promises to be a terrific resource. You may find it suitable to provide a link to my article titled: 'The Importance Of Viewing Environment Conditions In A Reference Display System.' It offers more detail on the subject of 'Room Considerations.' Joe Kane said many years ago that the viewing environment is the most neglected aspect of proper video display setup. It's still true today.

Awesome mech... thank you!

I wish we could get this into a magazine or even on a pamphlet of its own. One should be included with every display sold.

Amazing write up, it all makes sense and is written even in language which makes sense to me, Thanks!

I've beaten a lawman senseless. Fallen in with criminals. I watched the captain shoot the man I swore to protect. And I'm not even sure if I think he was wrong.

Lightbulb re: How to Setup your TV, HDTV, Plasma, LCD (Video Display)

Mechman,

Thanks again for all your effort in this thread. Reading through it again reveals some gaps I expect you intend to fill as you have more time to devote to its expansion. You have digested a lot of material over your years of accumulated study and practical experience. Hopefully, this thread can serve as a way for readers genuinely interested in video quality to learn the correct facts, dispel common myths, counteract marketing hyperbole, and equip them with practical solutions.

All of life is built upon certain fundamental principles that cannot be ignored or contradicted without unavoidable consequences. Video display setup is no exception. Understanding the fundamentals of video performance is necessary to avoid confusion and separate what is correct and beneficial from what is erroneous and deleterious.

One thing I see lacking thus far in your thread is a general introduction, or preface to your subject. That could serve as a way to inform your readers of vital video fundamentals from the outset. One suggestion to consider as an example is this article: 'What Is Video Display Calibration?' It basically introduces the principle that video picture quality is based upon standards, not any individual viewer's preference for what looks good to them. It also presents the notion that video programs are an art form, not just pictorial information in motion. At the very root of understanding video picture quality is the concept of image fidelity. Not comprehending that principle has resulted in massive confusion and disagreement in every home theater discussion venue. This is why Joe Kane has as his company's slogan or motto: "It's all about the art."

Another vital and fundamental principle that helps in proper display setup is to keep in mind that the display is only one component in a system. Every other component in a video display system must be considered in an interactive, integrated whole. You have touched upon this principle in a round about way. I just consider this principle foundational to getting the most out of a TV or projector.

re: How to Setup your TV, HDTV, Plasma, LCD (Video Display)

Alan,

We appreciate the input! And we are addressing how we're going to put it all together in the end. This sticky, as well as the DirecTV sticky and the recently posted AVR setup sticky are the spokes of the wheels. The main sticky thread (the hub, if you will ) will probably be where we put that kind of information. When it is finished and posted, I'll shoot you a pm to look it over.

Thanks again Alan!
