●
Progressive Scan
By utilizing the "scan Converter IC" to it fullest, the image and progressive scan are
improved.
* Compared to the LV-7555, the progressive functions are limited.
●
Start-up Display Customizing (Logo capture)
In these models the portion of the flash memory is reserved for "logo capture", making
it possible to save any image as data for use as the start-up screen.
5.3 Video Signal
Because of the compact design of these models, the number of connectors has been
reduced and given multiple functions. The user can select the correct signal on the
settings screen.
5.4 Mechanisms and System
These models were designed to be smaller, lighter, but brighter than previous models.
Layout and connector placement were thoroughly reconsidered resulting in a
significant reduction. These new models are less than 70% the size of the LV-
7355/7350/5200 series.
The LV-7215/7210/5210 share identical layout and as many parts as possible to
reduce development and production cost.
●
Heat and Noise Reduction
Special consideration was paid to preventing heat build-up in its compact confines.
Normally, many interior parts are coated with black nickel, which absorbs heat easily
causing heat buildup from the light absorbed. With these new models, the aluminum
surrounding the bulb has a thermal coating so the black nickel parts do not absorb
much heat.
Furthermore, by optimizing the exhaust fan airflow, very quiet (35dB) operation is
possible in Silent Mode.
* When temperature is low, automatic fan control reduces the exhaust fan's speed and
fan noise is reduced as in earlier models.
●
Lamp Modes
As in the LV-7555, these models have three lamp modes:
In Silent mode the noise level and brightness is controlled as follows.
Auto Mode controls the brightness so dark areas in scenes are not lost.
