I need some technical help with a computer monitor problem.

In our dispatch center, we run two standard style monitors and a couple of radios. They are spaced far enough apart from each other so not to cause interference.

Now, we are re-designing our console. We must move one of the monitors to another location which is about 12" closer to the primary radio. When this radio is keyed up, there is a distinct "hum" in the background. I assume this is caused by the monitor's electronics since it did not do it before it was moved.

Now, another question/scenerio. We may have to replace this monitor. If we do, we want to go with a flat panel LCD one. If we did, does this type of monitor emit the same interference as a standard screen one?

The CRT has a big magnet in it that directs the beam to draw the picture on the screen, an LCD does not.

I used to work in a hospital, there was this 1 group of people that sat over a generator or some kind of power equipment, their monitors where all kinds of pretty colors, even with extra shielding. They got LCDs way back when 15" ones were like $1500 each.

So a swap to LCD would solve it.

How much are decent 15"-17" LCDs?

Maybe $3-400. I'd look up some reviews on or and see what they recommend.

See, you could have had all your questions answered in OAF.

With the way prices are going, I might consider an LCD. The only problem I have with them is the whole "native resolution" issue, unless of course that is false or has been addressed.

This monitor will be used for a CAD system. Since one screen stays up for a while, is there a big problem for burnout like a regular screen? I honestly don't know. My laptop's screensaver turns on fairly often, but the one at work will not be able to turn on very often due to use.

Today's monitors and LCD's are all Energy Star compliant, and use a different phosphor coating (for CRT's) than the monitors of old. You can leave them on 24/7 and not worry about burn-in (having flashbacks to the old monitors at 7/11).

LCD's are liquid crystal and are constantly moving, so there is 0% chance of burn in. You're more likely to have a few pixels "disappear" than anything else.

Decent selection, not the biggest names but they have good prices. My brother got his flatscreen monitor from them a year ago and hasn't had any problems. I know many people who've been happy with their purchases from Tiger.

Another vote For NewEgg! Their site is very easy to navigate just take the reviews with a grain of salt.

Our dispatch center uses HP flat panels. We have a couple hundred. Like a typical government agency I'm sure it was a matter of who would give the lowest price, but they work and look decent.
