Are CRT monitors completely obselete now?
They are extremely large in comparison to LCD monitors, and they require far more power. So yes, CRTs are typically considered obsolete by today's standards, especially with the introduction of LED LCDs, which have a far better black level and color contrast. LED/LCD monitors also have far greater resolution, since a typical CRT resolution is about 480i, while LED/LCDs can handle resolutions up to 4K. LED/LCDs have much sharper picture, due to higher resolution, and modern LED/LCDs don't have the motion blur problems that earlier LCDs had. These factors make modern LED/LCDs better than CRTs in almost every aspect, and are the cause of CRTs becoming obsolete.
Are there magnets in CRTs?
Yes, there are magnets in CRTs
What are the advantages of LCD monitor over CRT?
CRTs don't have a 'native' resolution, which means they can display a range of resolutions comfortably depending on what you prefer. LCDs can too - but anything apart from native won't be sharp. CRTs also generally support higher refresh rates, so aren't prone to tearing as much. Tearing can be resolved by ensuring VSYNC is enabled in whatever game you're playing.
How many high school CRTs do you have?
yes
What are LCDs and how are they used?
An "LCD" is a Liquid Crystal Display. LCDs are used as parts of computer monitors and as displays in calculators, watches etc.
Why does a CRT monitor flicker when shot with a digital camera where as LCD monitor doesn't?
It has to do with the refresh rate. CRTS refesh the screen at a lower rate than LCDS. Although it is possible to raise the refresh rate to a maximum of 75 HZ a second or 75 images a second the digital recorder will record at higher than this so we see the refresh occuring.
Why are LCD monitors so popular?
LCD monitors are a cheap technology that present a pretty decent picture and can achieve a decently high resolution, while LEDs are more expensive with a better picture, and CRTs give off radiation and can't achieve a very high resolution. LCDs are very favorable monitors for their price, and decent picture quality.
How do LCDs produce color?
By stabing it in the face
What is the proper way to dispose of outdated CRTs?
Handle monitors and CRTs with care. Extremely high voltage can be stored in monitors and CRTs, even after being disconnected from a power source. CRTs contain glass, metal, plastics, lead, barium, and rare earth metals. According to the U.S. Environmental Protection Agency (EPA), CRTs may contain approximately 4 lbs (1.8 kg) of lead. Monitors must be disposed of in compliance with environmental regulations.
What kind of ray is in the CRT?
CRTs use an electron beam.
Lcd or crt?
LCDs are much higher resolution.
How many watts does a televion use?
It entirely depends. Since different models and technologies of television are not the same, they can vary greatly. Typically, LCDs using LED backlights are the most efficient, using around 40 watts for a 30" screen. LCDs using cold cathode, neon, and other backlights use a bit more, usually around 50-60 watts for a 30" screen. CRTs are less efficient, using a more formidable 100-240 watts for a 30" screen. Plasma is the least energy efficient of all, consuming a whopping 150-300 watts for a 30", although most are larger. a 42" can easily consume a kilowatt! Unfortunately, I have no data regarding DLPs, OLEDs, CMDs, or projectors, although I know OLEDs are supposed to be more efficient than LCDs.
