Dear CNET members,
Happy Friday! I'm really glad that George submitted the question on the advantages and/or disadvantages of LCD (liquid-crystal display) vs. CRT (cathode-ray tube) monitors, because I'm sure many of you (like myself) are on the fence about switching out those CRTs for LCD monitors. While CRT vs. LCD is probably a highly debatable topic, in a few years, as LCD technology becomes increasingly competitive with CRT display qualities and prices continue to drop considerably, CRTs may be a thing of the past. But until then, we'll let our community members chime with their say as to the advantages and disadvantages of LCD vs. CRT, so that we can make the best decision on which way to go. So let's get started with Paul's winning answer (five-time winner) that goes over some great, detailed explanations on CRTs and LCDs. But don't stop there, because we have many great honorable mentions and additional advice from our members this week. And if you personally have switched to LCD monitors or have refused to switch, please join us in this week's discussion and give us the full details on your personal experience with LCDs vs. CRTs. We all want to hear it.
BTW, if you are submitting an answer for the question of the week, please be sure to go through the Q&A guidelines. Unfortunately this week, we discovered a few submissions that were straight copies from other Web sites, which was not cool at all. While we don't mind you including information from other sites, please cite the resource to give those people credit for the information provided. Thanks, everyone, for your participation and have a great weekend!
(Note: I will be taking some time off to celebrate holiday festivities including the New Year, so there will be no member Q&A in next Friday's newsletter and no newsletters sent during the last week of the year. However, I will have some community buzz for you to discuss through the holidays and many more newsletter to come after New Year's.)
Member Question of the Week
A CRT flat-screen monitor not only has a much larger viewing
area and resolution rate, it's a lot cheaper than comparable
LCD monitors. Other than size and style, what are the
advantages and/or disadvantages of using an LCD monitor over
a CRT monitor? And if I were looking into purchasing an LCD
monitor, are there any specific things, such as contrast
ratios, refresh rate, and so forth (which is all foreign to
me), that I should pay particularly close attention to in
order to make a good buying decision on an LCD monitor? I
would be grateful for any detailed explanations. Thanks.
Hello, George. Let's try to help you decide what type of monitor to buy. I will try not to sway you one way or the other; however, LCD monitors show obvious advantages, while CRT do not. For reference, LCD stands for liquid crystal display, which uses two sheets of polarizing material with a liquid crystal solution in between. When electric current passes through the solution, it causes the crystals to align themselves so that light can't pass through them. Each crystal is like an on\off switch--either it allows light to pass through or blocks the light...

do I start?
Hooray! Member jjwoolf has decided to take the plunge and build a computer for himself. But he wants to know where to start and was wondering if there are instruction manuals that come with all the parts? Or is there a single manual you can recommend or an online tutorial? He's not afraid of trying but needs to know some basics to get started. Can you help him out?

Is it risky to leave external hard drives always on?
Member anonymuse writes: "I often read that people turn their external hard drives on only when they need them. Are external hard drives (in general) constructed to work like this, or is it OKto leave them on all the time? Sometimes I leave my external hard drive on for a few days at a time so that I can upload a torrent of DVDs of the kiddos to the grandparents. Am I putting myself at risk?" If you have answer for him, chime on in.

Warning! Firewalls are useless
Member doniel posted the above subject line in the forums to get your attention. Just recently, he discovered that after installing a program and reading the EULA (end user license agreement), he found that this program was allowed to bypass the firewall on his system. With this finding, he quickly wanted people to be aware that their systems aren't as secure as they think they are with a firewall. Check out his post and the response he got from other members. This topic is definitely worth reading about and also
to be aware of.

Firewall software needed with router?
Do you run a firewall on your computer? Is it hardware- or software-based, or both? Is one firewall sufficient enough to protect your computer from intrusions, or would it be best to have both hardware and software firewalls running at the same time? Join this discussion and let our members know what the best practices are.

Check out next week's question:
I've had the same desktop for a few years now, and I'm worried about the machine overheating due to dust blocking the fan and getting in the case. I'd like to clean up the inside of my machine, but I afraid I'll damage it. What's the best, safest way to clean up all my PC components? (I've never touched or seen the inside of my machine.) Also, are there any additional precautions I can take to keep my PC from getting so grimy in the future?
