Cromaclear is a trademark for CRT technology used by NEC during the mid to late-90s. This adopted the slotted shadow mask and in-line electron gun pioneered by the 1966 GE Porta-Color and used by most then-current television tubes to computer monitor use.
The shadow mask is installed to the screen using metal pieces [350] or a rail or frame [351] [352] [353] that is fused to the funnel or the screen glass respectively, [258] holding the shadow mask in tension to minimize warping (if the mask is flat, used in flat-screen CRT computer monitors) and allowing for higher image brightness and contrast.
This used a system in the monitor to scan the display line-by-line, which sent signals to the printer where a one-line-tall CRT duplicated the image on thermal paper. [10] Normally selling for $3,550, a $3,950 version allowed the printer to be shared among four terminals. The printer adaptor could be pre-installed in the 4010, making it the ...
Before the mid-2000s, most monitors used a cathode-ray tube (CRT) as the image output technology. [1] A monitor is typically connected to its host computer via DisplayPort, HDMI, USB-C, DVI, or VGA. Monitors sometimes use other proprietary connectors and signals to connect to a computer, which is less common.
The original lineup consisted of the KX-20xx1 20" and KX-27xx1 27" monitors (the "xx" is an identifier, PS for Europe, HF for Japan, etc.) the VTX-100ES tuner and TXT-100G TeleText decoder. They were often used with a set of SS-X1A stereo speakers, which matched the grey boxy styling of the suite. [20]
The most common technology for monochrome monitors was the CRT, although, e.g., plasma displays, were also used. Unlike color monitors, which display text and graphics in multiple colors through the use of alternating-intensity red, green, and blue phosphors, monochrome monitors have only one color of phosphor (mono means "one", and chrome ...
The bigger the screen, the greater the weight, and the deeper the CRT. A typical 80 cm (32 in) television can weigh about 70 kg (150 lb) or more. The Sony PVM-4300 monitor weighed 200 kg (440 lb) and had the largest ever CRT with a 110 cm (43 in) diagonal display. [14] SlimFit televisions exist, but are not common.
The Precision CR30, Sencore CR-70 and Jackson 707 are some of the CRT testers that are capable of testing the 7JP4, 3KP4 and other electrostatic deflection CRTs. Since the availability of these CRT testers is very limited, the prices for such testers are steep, so many restorers test these CRT's on a working TV set that used electrostatic CRTs.
