While LCDs have at least two considerable advantages :
- power saving (good for your wallet)
- no flickering (good for your eyes)
1. CRT consumes ~100W (my 17'' Mitsubishi - 96W ) it's like ONE light bulb :) It's a myth that CRTs are power greedy.
2. Modern good monitors @85Hz and more give quality stable picture for eyes.

1. 100W, quite enough. While CRT monitors can easily suck over 100W of power, LCDs typically consume less than half that. For those looking to keep power consumption to a minimum, LCDs definitely have an advantage, and because the screens run on less power, they also generate less heat. Again, power consumption and heat output probably aren't going to be huge concerns for anyone running a single monitor, but a small office can get pretty sweaty with even a couple of big CRTs. Appeals to power saving are ecologic mottos of modern days. Well, maybe not in your neighborhood...
2. While frequences over 70Hz are considered as ergonomicaly sufficient to prevent eyestrain and connected headaches, your brain processes the flickering even though your eyes don't recognize it. Even high-end CRTs fed by strong video signals can produce eye strain after extended periods of use, but LCDs are much easier on the eyes. This effect isn't always immediately apparent, because it generally takes hours for eye strain to manifest itself with a decent CRT setup. Spend extended periods of time with a CRT and LCD side by side, however, and you'll find the LCD is a heck of a lot easier to look at, especially when it comes to working with text. There is also general rule that higher frequences wear out your screen over time, which of course varies depending on their quality.
3. CRT's radiation ... nuff said.
Both standards have their good sides and bad sides. I agree that CRTs are better for certain activities, like playing games and watching movies, editing graphics and photographies, while LCDs seem to be more suitable for general office work and text typing.

LCDs are much, much better for your eyes because of their technology and no CRT can beat that, 242. I used to have headaches when spending more than a few hours using the computer, even with a quality CRT monitor. Not anymore, with my new LCD.
The only real disadvantage is the lack of true black color (which can be partially fixed by buying a higher quality LCD with better contrast ratio). Thief doesn't look as good as it used too, but it's still quite bearable.
Oh and hello fellow Slovakian :cool:

redface, hey there bro ;)
Actually it's not so simple with that power consumption. Manufacturers usually put on labels the highest possible peak power output. But the output usually depends on more factors and varies according to settings of your monitor, and also on varying power input from power grid (I'm not sure here, ask your nearest electrician for details). For example, if you have screen brightness pumped all the way up, your monitor consumes more than if you have brightness set up somewhere in the middle of the scale, although I don't think the difference would be more than +- few Watts.

Exactly what I think.
PS: Your sytem block consumes 200-400W, 2-4 times more than CRT. Do you think about cost of electricity when you decide to install one more additional light bulb at home? Rhetorical question :)

Wow, usually I find myself explaining the pros and cons of LCDs and CRTs, but it seems it's all been covered for once.
LCDs are the best choice for work, that does not involve colour.
CRTs are the best for entertainment and work that involves colour.
LCDs are an especially bad choice for Thief because it is really cool to play this game with the lights out, to maximise the contrast ratio of the CRT monitor.
With an LCD this actually makes it worse because the backlight shines through all the supposedly dark areas and makes everything washed out.

My power supply can consume up to 400W, yes. Just my graphics card can eat up to maximum 75Watts (PCIE interface can deliver that much).
Well, my power saving philosophy is that I have electric devices turned on only when I really need them. Better said, I try to keep this conduct. For example I don't have chandelier in my living room lit up when I just watch the TV at evening, neither when I work with computer, only one of my small lamps with 25 - 40 W bulb. Certainly there are some power-consuming things in household which you essentially need for your life, but then you can spare power elsewhere.
Another thing is that your electronic devices like VCD/TV/DVD/soundsystem in standby mode also consume some energy. It's not much, but if you have more of them and almost never completely turn them off, if you sum up their overall standby power consumption, it's a decent number, say for a month.
That's why turning electronic devices completely off is a good thing, if you don't need them to automatically turn on at certain time. And there are those power saving "lightbulbs" of course... there are many possibilities how to save power. I still use a CRT, which is actually 5 years old, but when it finally dies, I will certainly buy LCD, despite it's obvious disadvantages. I expect that by that time they'll be cheaper and even more sophisticated. And I'm grateful for LCD I use at work. When I imagine that back when I was buying my CRT, it was as expensive as 17'' LCDs are today...

yer but they shoot electrons at you, which is never good.

If you think that question is rethorical then you've obviously never spent a thought about your electricity bill. By replacing all light bulbs with energy saving bulbs and turning off all unused devices with switchable sockets I've managed to cut down energy consumption by 1500 kWh per annum, saving about EUR 300,-. (By the way, my whole system consumes about 80W at peak times; I think the TFT screen is responsible for about 15W).

Thief looks fine on my home TFT and poor on my laptop's TFT screen.
I wouldn't ever go back to a CRT now but I do admit they have a better colour representation than TFT.
