chatodic monitor, worth upgrading?

[noxiousvegeta]

Hello, i use a chatodic monitor for gaming about 4 hours a day.

How much power would i save in a year if i move from my Philips Chatodic Tube 18,5" monitor to a led Monitor of the same size 18"5 with a usage of 4hours each day?. Thanks!

For your information you mean a CRT or Cathode Ray Tube monitor, which consumes 80 - 120 watts in your size.

 

Modern replacements are LCD at 40 watts and LED at around 20 watts.

Plug energy monitor (it's quite cheap, something like $20)

Like this

And you will know exactly how much device in your house is taking energy.

 

If you will record 120 W (as Studiot worst case) and drop to 20 W, it means 100 J is saved per second.

100 J/s * 3600 s * 4 (h) * 30 (days) = 43.2 MJ

1 kWh = 3.6 MJ, so

43.2 MJ / 3.6 MJ = 12 kWh saved per month. 144 kWh per year.

 

I am using 330 kWh per month. So 12 kWh from 330 kWh is just 3.7% less... That would be 2.5$ less on bill..

 

Never mind power, health is more important.. CRT is accelerating electrons and hitting them on screen, creating x-rays. That's why it has so bold lead glass screen for protection. But it can't absorb everything with 100% accuracy.

It's definitely worth upgrading I got my new monitor second hand for $28(pawn shop). Even without the electricity costs I move my computer about twice a month and the old monitor weighed a ton. There is space considerations as well I can wall mount the new monitor so I don't need to have it on my desk all the time.

I don't recommend you buying used one.

 

Personally have dual-setup Samsung SyncMaster SA300 S24B150BL 24" LED.

It's 16:9, Full HD. With good quality.

 

On 1st I see stock market on-line charts, on 2nd I work.

 

It looks like this:
