Has this happened to you?
- You purchase a TV that looks great in the store, but when you get home and set it up (or have it set-up for you by a mass market retailer), the picture looks mediocre at best?
- The "killer" surround sound system you bought turns out to sounds tinny and unclear?
The difference between a calibrated home entertainment system and an un-calibrated one is dramatic, and should be experienced first-hand to be believed. When we show you the difference, you'll realize you're valuable money spent on un-calibrated video and audio components is largely wasted.
Dave's Home Theater brings a serious commitment to the science of home entertainment system calibration. Whether you want us to set up your HD plasma to look its best for game day, or a detailed acoustical analysis for your home theater system, we make it happen so that your home entertainment system is delivering all the pleasure and all the excitement you deserve.

Click Ring ME Buying a new television is often fraught with difficulty. The vision you see on screen in the store showroom may look totally different when you take your new TV home.
Why? Well, a couple of factors come into play. In store, you're probably looking at a high definition feed (good) that has been split to display on multiple screens (bad). And often times, floor stock will have their picture settings cranked up to artificially high levels to stand out in the usually poor artificial lighting conditions in the store.
At home, with different input sources -- broadcast television, DVDs, game consoles -- different video connections -- HDMI, component, s-video and composite -- as well as different lighting and background environments, the images displayed on your new tv may not be what you expected. Fiddling with the contrast and brightness controls may help, but it can be a hit and miss affair. How can you tell which are the "right" settings?
Display calibration professional from Dave's Home Theater, says that ideally your television can be set to meet film and broadcast standards, developed by the Imaging Science Foundation (ISF), so that its displays the images exactly as produced and intended by the content's creators. Calibrating your screen to reproduce these standards in your unique viewing environment and accommodating the variations from your particular source equipment can have surprisingly impressive results.
In addition to optimizing the display with correct color reproductions for your equipment and room lighting conditions (professional calibrators will do both Day and Night settings), proper calibration will give you full detail with no artifacts in both the bright and dark areas of the picture. The result should be a more three-dimensional "immersive" viewing experience, with less eye fatigue as well as an extended lifespan for the display.
We measure on screen data to analyze the display using test instrumentation
with a Color Analyzer/Spectroradiometer while using test DVD’s and a Test
Pattern Generator to see what has to be adjusted in the display itself.
We correct the basic Contrast, Brightness, Color and Sharpness controls of the
set and then make more advanced adjustments to correct the grayscale. All
adjustments affect one another so a calibration can take quite some time. As you
can see below, incorrect settings do affect picture quality degrading it
somewhat.
Most televisions come out of a factory at a Color Temperature setting from
8000 degrees (Kelvin) and beyond, this yields a very inaccurate picture with a
very strong push of blue present in the display. This is done by manufacturers
to make their sets stand out from others. For the average consumer, a display
that is bright and vivid can be very appealing. These days some professional
models and manufacturers are starting to realise the importance of calibration,
but there still is a persistence among manufacturers for shipping their displays
with an incorrect colour balance, which means corrections are needed to be made
to achieve an accurate image.
The Greyscale reproduction plays a huge part in image quality. Throughout the
Grayscale, from 0-100 IRE, a device has to be calibrated with a perfect balance
of Red, Green and Blue. Without a perfect balance, a set will show signs of a
push to one color, but don't get this confused with a Color Decoder push. For a
display to be accurate, it has a point known as D65 with set "x" and "y" points
in the CIE Graph.
Many people confuse 6500k with D65 which is situated along the black body curve
with specific “x” and “y” coordinates. 6500k is a Correlated Color Temperature
and even with a display set to 6500k, a device can still show signs of a
green/red cast over the image, this is because the "x" and "y" coordinates are
not set correctly. As you can see, the first two images below show why you
shouldn’t just consider 6500k as being correct and what it looks like with a
color temperature too low or too high. The last image has been calibrated to the
correct reference.
The whole Grayscale from 0-100 IRE will show a consistent and gradual stepping of gray window patterns to confirm its accurate and with the test gear, this can be shown to the customer with before and after readings. A report can be sent to you by email for the readings that were taken during the calibration for your own reference.
