CRT v LCD Monitors

dts1

I am looking to justify the purchase on LCD monitors in bulk and need to justify for the company.
Does anyone have any means of justifying the purchase of over 100 LCD flat screens.
We live in a very different world to get monies now than even over 2 years ago but i need to eplace these CRT monitors.

I know there is an energy saving with LCD's over CRT and over time LCD's have become more cost competitive with CRT's.

I suppose the key thing for the company is to show where payback can be achieved.

Are LCD's known to last longer than CRT's ?
How more energy efficient are LCD's than CRT's ?

Any comments are appreciated.

We have a store of about 900 LCD's. I have seen about 10 fail in just under four years.

They are lighter which alleviates health and safety concerns for moving them and storing them, use on average 50% less power(crts are at about 90-120watts) and they provided greater desk space.

I think the real question here is, in 2010 what kind of complete tightwad company is still debating using them?

Skerries

can you still buy crt's these days?

The saving in power should justify it in the long term

Go for an LCD. Who has a CRT anymore

Nah seriously, they nearly all survive. Never seen one damage. I've one of the ones that came out first. 600 euro for 17" and it still going 6 years later.

LCD screens also are less reflective, so there's less eye strain/headaches.

There's EU directives that employees can demand anti-glare covers for their screens I believe.

Sure you can always throw in that CRT's cause eye cancer as a last resort.

I find looking at a CRT for 5 minutes tough going - never mind all day!

Here's what I can think of...

• Lower running costs.
• Increases user desk space.
• Easier to move - reduces risk of injuries during desk moves etc.
• Generally height adjustable without additional accessories. Health and safety will like this.
• Makes your company like like it's not stuck in the early 90s.

and probably increased productivity in the company.

True, especially if the screen size will be bigger than what they currently have with the CRTs. Less time flicking between apps, scrolling windows etc. All those seconds add up quickly when they are multiplied by 100 users!

its easy to adjust a crt to a ergonomic, healthy viewing angle, you can give them to charity, or send em to a council waste center,which takes pcs/monitors.

Angle, yes. Height, no.

One more reason: they will prevent office jealously! If anybody new joins or if you have a faulty CRT it's likely you will have to replace it with an LCD (unless you have a room warehouse full of spare CRTs of course).

What kind of a price difference are you trying to justify? With the proliferation of LCDs nowadays I can't image there is a huge difference, unless you're getting 24 inch widescreens.

I think the OP wants to justify the cost of replacing their current working CRT monitors to his management team.

I can't imagine anybody is stocking CRTs these days for sale.

ricman

you can get rotatable lcds that can be moved to portrait mode, more effecient for writing or editing mode.in a few years the crts will wear out, buy 100 and you,ll get a discount on the price.

OP, if thats the case, I've a neat deck on the topic which was (successfully) sold to senior management.. based around cost vs energy requirements, ergonomics etc.. pm me if you want a copy!

Does anyone know how much of a power saving in watts you are making by comparing a 19" CRT monitor v's a 19" LCD Screen.

A survey concluded that comparing a 15" LCD monitor with a 17" CRT monitor (which has an equal amount of viewing area), the LCD monitor used 55 watts less when operational (25 watts vs. 80 watts) and 2 watts less when in standby (3 watts vs. 5 watts).

Not to mention eye-strain concerns using the old CRT screens. They work by blasting Cathode rays at a phospor screen which absorbs the ray and emits it as visible light. The problem is this phoshpor layer is finite. As the monitor ages more cathode rays permeate through the screen and you're essentially blasting your employees in the eye with straight electrons. Nevermind Ionizing Radiation. While it's not enough to be considered harmful, why expose Bob from accounting to Ionizing Radiation? He just wants to balance the Cost of Goods account.


On the energy argument, you save more wattage on the newer LED screens, which throw out the Fluorescent backlight and use a grid of LEDs that use up a fraction of the juice.

There are also the aforementioned advantages of precious desktop real-estate savings, and giving your workers the sense that they aren't working in an office that hasn't upgraded since 1998. Cos let's face it: having modern **** makes us feel good.

Personally I rather the picture on a CRT, but for office space it's a no brainer - LCD all the way. It's not like employees are going to be watching video or playing games.The reclaimed desk space alone is worth the change over.

And as for the 'who still has a CRT question' I do! I have one for my old videogames consoles. They look amazing on a CRT through RGB scart with scanlines. Plus there's the oul LCD lag to think about too.

But anyway, I'm getting off topic. Get some LCDs for that office. I couldn't imagine working in a modern office full of CRTs.

Very good article Broken Arrows. Thanks.
The article states, that an 19” CRT monitor uses 110 watts while an LCD of the same size uses 45 watts.
By stating it uses less watts, is this per hour/per usage ?
By using less than half the amount of watts, is there a way of associating this saving with money. How much money are you saving by the LCD using less than half the amount of watts of a CRT ?
If i was to buy 200 new LCD's, what would i be saving i guess compared to buying 200 new CRT's ? (which i know i probably couldn't buy anyway !!)

You need to figure out what you are paying per watt now. Or if your company is on a fixed usage rate.

lets say your company pays 10c for 1kwh

the monitors are on for 10 hours a day. The CRT uses 1.1kwh and the LCE would use .45kwh per day

11c vs. 4.5c

multiply this by - how many machines in the building? Lets assume 200. And 300 days per year, over the course of 5 years.

CRTs would cost €33,000 to run for 5 years; LCDs would cost €13,500

You would save €19,500 which would give you a maximum of €97.50 to spend on each screen to break even after 5 years: they would pay for themselves. Presumably sooner depending on the use-habit of the screens.
