Vizio VO47L LCD HDTV Review
The VO47L manages something of a tightrope act; keeping the price down, while still producing decent quality.
To get the best out of a display, it has to be calibrated, a process that finds the correct settings for the individual display. We use the DisplayMate calibration process to set the display up correctly; the calibrated settings that we use are listed below.
|Setting||Default (standard mode)||Calibrated (custom mode)|
|Color Temperature B||128||109|
Part of our standard calibration process is to put the backlight to maximum and then to find the settings that produce the closes to 6500k for the color temperature. For this Vizio, none of the color temperature settings were particularly close, so we used a manual setting.
the VO47L is built around a thin film transistor (TFT) active matrix display, which has full HD resolution and a quoted dot pitch of.5415mm on both the horizontal and vertical dimensions. To further examine the specifics of this, we look at the dot pattern of the screen using a microscope. The photo on the right (taken at a 20x setting with a microscope), shows the dot pattern of the display and the slightly unusual sideways-V shape of the LCD elements; each < shape is a single element. They are in groups of three; one red, green and blue element forms a single pixel. Because they are so small, the eye blurs the colors together to form a single color. In this image, the screen is showing white; all of the elements are active.Vizio does not reveal the number of individual elements, but given that this is a Full HD display, there are probably around 5760 horizontal and 1024 vertical.
