Computer Monitors
Computer monitors are television-like devices used to display graphical information from a computer. They have been the primary form of displaying output to the computer user for decades. Questions about computer monitors and monitor display technologies belong here.

Why does the picture on the tv screen become distorted when a magnet is brought near the screen?
A strong enough magnet brought close enough to the screen or to certain other parts of a television or computer monitor that uses a cathode ray tube will distort the displayed image.
This happens because a cathode ray tube image is created by shooting electrons at a phosphor-coated layer that glows where the electron stream strikes it. The stream of electrons is focused and targeted by magnetic fields within the TV tube. A strong enough magnetic field from another source will send the beam of electrons off target, distorting the image.
This does NOT happen with modern flat screen TVs and computer monitors because they do not use cathode ray tube technology to create the image.
The picture as seen on TV screen is due to moving charged particles (electrons).
How can I switch my computer's voltage from 220V to 120V?
In the United States 240 volts is produced by two 120 volt hot wires 180 degrees out of phase. Added together the voltage difference is 240 volts. To get only 120 volts one of the hot wires needs to be replaced with a neutral wire.
That would make the voltage difference to the neutral 120 volts. (There may or may not be an existing neutral wire running to the outlet. Whether there is one depends on the purpose for which the 240 volt outlet was originally installed.)
It is often not worthwhile to change the existing 240 volt outlet - it is often best just to leave it there to power 240 volt appliances.
A licensed electrician would know how to check this for you and would advise the best action for you to take. He would use the correct size of wire to supply the current required by the 110 - 120 volt appliances you want to use and connect it to the correct sizes of circuit breakers on the main panel and also a GFCI safety device to protect users from electrocution if the room is likely to be damp or have water spray or wet floors, walls or ceiling, such as a laundry room or a kitchen. All this is necessary to comply with the latest Wiring Codes in your locality. (Town/State.)
Then you would be able to use a 110 - 120 volt appliances safely in the room in question.
<><><>
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

What graphic uses colors of dots or pixels?
Vector Graphics - is the first term that comes to my mind. You may also be asking about Pixel Art, which are graphics created by using tiny pixels.
How do you solve the total risistance if it has 4 resistance and resistance 2 and 4 is unknown?
R1+R2+R3+R4........................ To get total Resistance
according the above formula if risistance R1 12v And R2 13V then by sustituting the rest ...........
Can you get delay when using higher quality monitors?
Depends on the monitor in question. Find the devices data sheet and look for the Display Latency (or something similar) anything under ~1 milliseconds is not noticeable. This latency is the amount of time it takes from the monitor's controller to push the data to the display after it has been received. If you are just watching a movie this really doesn't matter, but if you are playing a video game or something that requires the monitor to update as soon as the this latency can play a big factor in the usability.
What should an overweight 12-year-old boy with larger-than-normal breasts do about their condition?
I suggest you see your doctor. You probably have excess body fat, and maturing boys often get 'breast buds' which disappear as they get further into puberty.
Is remote infrastructure monitoring and network monitoring same?
Sort of. Remote infrastructure monitoring would fall under network monitoring. Network monitoring in general focuses on the monitoring of your network infrastructure: things like switches, routers, etc. Remote just means your monitoring it from outside the network, and is a feature available in many solutions.
What is the solution for a monitor that is on but the screen is black?
Try another monitor on the computer and if it works correctly then the monitor is defective. Buy a new one, as it will cost more to repair than to replace.
What to monitor for a patient taking chlorptomazine?
When monitoring a patient taking chlorpromazine, it's essential to assess for extrapyramidal symptoms (EPS), such as tremors or rigidity, and monitor for signs of sedation or drowsiness. Additionally, evaluate for potential side effects like weight gain, metabolic changes, and anticholinergic effects. Regularly check blood pressure, as chlorpromazine can cause orthostatic hypotension, and conduct routine blood tests to monitor for agranulocytosis or other hematological changes. Always ensure kidney and liver functions are assessed, given the drug's metabolism and excretion pathways.
Give an example of two output devices and what the do?
Monitor- displays text and graphics.
Speakers- plays sounds.
What is broadcom gigabit integrated controller?
A broadcom gigabit integrated controller is a tenth generation 10/100/1000 base-T Ethernet LAN controller solution. It has high-performance network applications.
If Liquid-crystal display will disappear slowly?
While it is possible that newer display technologies may eventually replace liquid-crystal displays (LCDs), it is unlikely to happen quickly. LCDs are still widely used in TVs, monitors, and other devices due to their affordability and reliability. Any transition to new display technologies would likely be gradual over several years.
Dot pitch and DPI are both measurements related to?
Dot pitch refers to the distance between dots or pixels for computer printers, scanners, monitors or other pixel-based devices. DPI, or dots per inch, is similar in the devices that it supports, but instead measures the number of individual dots or pixels that fit within the span of an inch.
What kinds of things contain LCDs?
In a "transmissive" type of LCD, this light is provided at the back of the glass "stack".
What does cylinder 4 misfire detected mean?
It means the #4 cylinder is misfiring. Can be bad plug, plug wire, burnt valve or blown head gasket. Replace all the plugs and wires and see if the misfire goes away. If not, run a compression test on all cylinders.
How do you adjust the touchme screen?
More information is needed. What device is the screen on - make, model, etc? Have you read the manual or searched the manufacturer's website?
