What is a measure of how many spots on a crt screen are addressable by software?
This is called "resolution." It is typically two numbers, such as 1024 by 768. This is the width and height of the screen in pixels.
For CRT monitors is a measure of how many spots on a CRT screen are addressable by software?
resolution
Lcd or crt?
LCDs are much higher resolution.
How large is 300px?
The physical size of a pixel is going to depend on the resolution of the device displaying it. Resolution is typically measured in Dots per Inch (DPI). The general formula to convert from pixels to inches is: Pixels / DPI = Size in Inches. For example, at 75 DPI (typical CRT display) 300px would be 4 inches; while at 150DPI (typical cell phone display) 300px would be 2 inches.
What are the disadvantages of crt and flatcreen monitor?
CRT: Use more power, lower resolution LCD flat screen: price
Why the number of pixels in LCD is more than the number of pixels in CRT?
The way a CRT (Cathode Ray Tube) works is very different to LCD and plasma screens. An LCD screen has discrete pixels to generate the image. It is possible to see each one and count them, if you feel so inclined.A CRT on the other hand uses a continuously moving electron bean that is focused on a tiny part of the screen. There are no pixels as such and the resolution of the screen is dependent on how fine the electron beam can be focused.In the early days of HD television, CRT monitors were developed to handle HD resolutions and the image quality was outstanding on them. They all suffered from one big drawback, namely the price. At thirty thousand dollars for a small monitor, they never found their way into the residential market and even the broadcasters balked at paying that amount. The development of ever better plasma and LCD televisions very quickly killed off any chance of the HD CRT being seen in homes.
Is a measure of how many spots on a CRT screen are addressable by software?
The total number of spots on a CRT screen that are addressable by software is called screen resolution. Typical resolutions include 1024x768, 800x600 and 1600x1200.
What are the disadvanteges of a crt monitor?
It takes up more space and it has lower resolution.
What are the two differences between CRT monitor and a LCD monitor?
CRT monitors use a beam of electrons to form the picture - LCD's use microscopic pixels. CRT's need large amounts of electricity to form the picture - LCD's work with low voltages.
What are the basic principles of displaying an image on a CRT?
The pictures or graphics that you see on a computer screen are composed of just three colors: red, green, blue, or combinations of these three. The computer determines the appropriate color by the amount of light or color in conjunction with a numeric representation of the color. The technical name used to represent every color bit in a computer is a pixel or picture element. The pixel is a tiny square of color. Used in conjunction with millions of other pixels, it gives us an image that our eye can recognize. The number of pixels determines the quality of the cathode ray tube (CRT) on the screen. The higher the number of pixels, the better resolution you'll have. But mapping is the computer's technique to manipulate the pixels on your screen.
How many pixels are there in a Cathode Ray Tube monitor?
There aren't pixels as such. the face of the CRT is coated with phosphors that light up when electrons strike them. The equivalent pixels would be a function of beam size. Moving on to later color CRTs, there was a mask overlay to force a pixel effect and isolate the RGB beams to one 'pixel' area. Pixels don't become real until you have a true digital display when there are in fact individual pixels to light up.
Is there a high def CRT?
While there are high-resolution CRTs, they don't come in widescreen, so no.
