Magnavox RGB Monitor: Inexpensive Color

Any Spectrum or TS-2068 owner who has seen their model of computer running on an RGB monitor is never really happy with a color TV or composite color or green monitor again. Both computers require an adapter be purchased for such a hook-up, but the real problem is the cost of purchasing the RGB monitor.

While most monitors (and televisions) are prepared to receive their screen info from the computer on a single line which must then be “decoded” by the monitor to pull out red, green, blue colors, etc., the RGB monitor is different. Its signals are already separated before coming into the monitor. The monitor is designed to take these separated out color signals and show them on the screen to greatest advantage. Typically, a composite screen has trouble displaying clear sharp edges to lines and text characters are often fuzzy or have a ghostly duplicate. Borders where two colors meet have a “crawling” effect. All who use them know the effects well. (This is a layman’s description.)

However, RGB monitors are generally more expensive and more limited as to the computers that can use them. While a monochrome 12” monitor can be obtained for under $100 and a color TV for less than $200 (and can be used with almost all home computers), RGB monitors typically start at $325 and may require an adaptor ($50) and custom cable ($15+) before it can be used. A popular RGB monitor for T/S users is the Sears model which lists in their catalogs for $339 + shipping. Different than most, it has television, composite color, and green screen monitor settings, in addition to the RGB ability. This makes it a best buy for many computerists.

Now there is another choice available. Magnavox, also known as NAP, has introduced the RGB Monitor 40, a 18” monitor with a horizontal resolution of about 390 pixels, more than enough for the 2068 or Spectrum which produce 256 pixels across the screen. In addition, the QL does quite well with it if in 64 column mode and is very readable even in its 80 column mode. Both QL and Spectrum graphics are beautiful. The QL generates 512 pixels across.

The Magnavox RGB monitor comes well equipped. Three input modes are available as standard equipment: digital RGB (most computers including T/S), analog RGB ‘some Apple computers), and composite color. In addition, a green screen switch for monochrome display and an audio input and volume control can be used. Where many monitors only offer controls for brightness, contrast, color, tint, and vertical hold, the Magnavox also allows adjusting sharpness, horizontal hold, vertical and horizontal height and width. (very important for QL), and two switches to allow optimum viewing when used with a VCR or camera. Finally, a small built-in tilt stand can be used to angle the screen for more convenient viewing.

For all of these features, I was able to purchase the Magnavox RGB 40 on sale at Service Merchandise for $199!
