If you leave a computer on 24/7, is a LCD or CRT better?

Don't change your monitor due to this issue. You may leave your computer on "24/7" but your computer most likely doesn't leave your monitor on the entire time unless you're using it that much. If it is, you need to do something about it. Check your Monitor power settings (on the screensaver tab of your display properties) and set the monitor off timeout to something reasonable, like 20 minutes. If you don't use your system for that determined time period, your computer will signal your monitor to enter a low-power state in which it displays no image, therefore not burning any images in, nor wasting your power.

The problem with most current LCD technology is that the chrominance isn't as good as with traditional CRT-based monitors. There are some LCD ones just coming out that have full-color backlight which should make them actually _better_ than CRTs (according to some Wired article I read, anyhow.)\n\nPersonally, I've been pretty happy with the Dell 24xx monitors - they're under $1k, they have a multitude of inputs, and I think I've only got one stuck pixel (and no dead ones.) You're still going to have to color-correct anyway, but you'd have to do that on _any_ monitor you get. (A good gamma correction curve will solve a multitude of ills.)

well lcd lasts longer but plasma is visualy better, they both have upsides.

Easy, have them buy you a new monitor.  LCDs can have problems if too much pressure is applied.

if you have a lcd monitor there is no reason to have a screen saver. the images no longer get burnt into the monitor like they did in the old days of computing

No they do not require a screen saver.\nand\nNo. The do not burn-in.\n\nYou see LCD technology does not itself emit light, and the back-light is not strong enough to etch the glass over time.....\n\nPlasma monitor/TV's can burn-in though.\n\nPS: screen burn-in would never be called 'dead pixels'

If your computer can use a CRT, then it can use a flat panel.

"Flat screen" is usually in reference to the traditional CRT monitor, but the glass is flat. An LCD flat panel is indeed flat, but the best part of the LCD is that it is very thin and takes up minimal space. The flat screen monitors would take up as much room on your desk as any traditional CRT monitor. LCDs look nice as well!

Very little cost.  :)   Computers use very little power, and electrical power is cheap.  If you left your computer on 24 hours a day, you're probably using roughly 10 cents of electricity in a day.  Turning it on and off is hard on the hard drive.  Good rule of thumb is to turn it on when you go to use it, and leave it on the remainder of the day until you're done with it for the day.  You can turn on and off the screen, that'll increase your screen life.  But turning it on and off a lot puts stress on the hard drive.  Mostly leave it on once it's on.

Well, LCD's don't require much care, but if you want to keep your monitor in good shape there are a few things you can do.\n\nYou should never touch the screen. An LCD screen is sensitive and very easily damaged by both pressure and the oils from your skin.\n\nSecondly, like anything else, you should turn it off when not in use. LCD's don't suffer burn in like CRT monitors, but it's still a good idea to turn the monitor off to save power.\n\nThird, you should always keep your monitor clean. Never clean it with Glass Plus or ammonia based cleaners. Instead, use the cleaners suggested in your manual. The only one that I've seen do all my LCD's and other screens (CRT's, DLP's, Plasmas, etc.) is the Monster TV Cleaning Kit. Usually Monster Products are overhyped, but it comes with more value than any other screen cleaner then before. You get a gigantic bottle (can't notice how much I've used in 1 year- I clean often, and it looks like I haven't opened it), a large and nice microfiber cloth, and it is more effective- one spray will get you through 90% of the time, and always in two. Only $20, which is a small price to pay for an LCD monitor:\nhttp://www.newegg.com/Product/Product.asp?Item=N82E16812155532\n\nFinally, always handle your LCD carefully, at it is very sensitive to drops and getting "dead/stuck pixels" (either pixels that don't work or are stuck a particular color) from bad handling.\n\nIn conclusion? With a little care and caution, your LCD will work well for years to come.

A General rule of thumb is that if you have no good reason to leave your computer on don't.  You will lessen the chances of your computer being influtrated if it is not on 24/7.  However, you can leave it on if you wish but ensure that you have taken the proper precautions:\n1) Have an anti-virus program  (i suggest PC-Cillin by trend micro)\n\n2) Have a good Firewall program\n\n3) Have good proactive spyware program (i suggest Spy Sweeper by web root)

The physics and basic theory of the CRT (picture tube) have not changed at all. The electronics and such have been dramatically improved - but the electrons smashing into the phosphor and emitting light is the same.\nHowever, the newer Plasma, LCD and DLP sets are completely different.

I recommend leaving it on, provided--\n- If you are connected to the internet full time, you  have good up-to-date security software (firewall (software and on router), anitvirus, and spyware.  As added security, when not running scheduled updates over internet, many modems have an off switch; turn it off when not actively using the internet.\n- If you have an UPS.  While lightening over lines connected to the computer can destroy parts of it, a good surge protector works wonders--most of the time.  The UPS also answers the problem of low voltage spikes.  When the voltage drops and comes back up, without a UPS, your computer starts to turn off.  When the voltage kicks back in, the drive restarts after slowing which is hard on the drive.

BIG CRT :d the color and resolution are AWESOME.\nMinimum 21"!

Conserves energy, supports very high resolutions, portable, sexy.\n\nNote: Viewing angle is still a trouble..... you don't have that problem in CRT monitors. The picture becomes negetive & colour changes when we increase the viewing angle of a TFT screen.

1. I have a UPS hooked to my firewall / router and also have 7 networked systems, and keep three computers ON at all times.\n\n2. I have serviced delicate computers and peripherals since 1965, the first 20 years on active duty in the USAF.  Some were mobile, on the ground, or in the air.\n\nMy experience is that the systems left on all the time cost less to keep running, than the ones that get turned off and on.\n\nThe biggest user of energy is the CRT monitor, so they get shut off at night.  And, I am switching to LCD monitors, having three so far.  \n\nThe CRT monitors use between about 200 watts (15 inch) and 400 watts (21 inch).  The LCDs use 20Watts(15") to 40 watts (19").  The LCD monitors us less power when fully on than the CRT monitors use when 'asleep'. \n\nThermal cycles of Power On vs Power Off cause failure.  Many computers that have run successfully for years will not start back up, after they have been shut down.  \n\nIf parts are going to fail, it is usually during the surge of current flow upon start-up. \n\nAlso, Microsoft FAT, FAT32, and NTFS do seem to cause a higher failure rate than Linux EXT2/3, ReiserFS in all my experience.  One more reason I run http://pclinuxos.com

A CRT(cathode ray tube) display screen uses a "electron gun" to fire electrons at the phosphor screen, thus creating an image. The advantages to having a CRT screen over a LCD(liquid crystal display) screen is that it's easier to install, since almost all computers and its motherboards have the port integrated.\nThe disadvantages of a CRT screen, is that it's bulky(due to the size of the "electron gun"), and it produces radiation, which is received by your eyes when viewing the screen. Prolonged exposure to the radiation can cause discomfort(in terms of headaches and/or seizures).
