Hi :)

I am looking to purchase a TFT monitor as CRT's are taking lot of power and my inverter barely supports 17" monitor for 1.5 hours so I guess I have to use TFT now.:mad:

So which TFt will be best for me and for how much ?
 
which CRT do u hav?

model number plz...

1.5Hrs will be for ur pc wid crt...

shifting to LCD wont bring magical backup time to ur inverter.

most 17" CRTs consume 70-90W...

most LCDs consume 35-50W...

plz mention rest of ur config so that ppl can suggest if shifting to LCD will be of significant advantage after paying the premium.
 
Hi madnav, its a 4 year old system with Samsung (or LG, not sure) ViewSonic 17" monitor. I only run my PC with it and it runs for like 1:45 hours at max. I am looking to make it atleast 3+ hours and hopefully TFT can come handy here. The monitor is also pretty old so I guess its good time to move on.

any suggestions ?
 
ur rig details are very low here.

but acording to your requirements... i will try to generalise this whole thing to give u an idea abt how much power is being used n how much will be used in order to increase that pc backup time from 1:45hr to 3hr....

We will Assume..

t = 1:45hr = 1.75hr

T = 3hr = 3hr

X = PC power Consumption Excluding the monitor/display

Y = Capacity of Your Inverter...

CRT Power Consumption = M = 90W (Maximum)

LCD Power Consumption = L = 35W (Minimum)

We have two equations as per ur provided info..

we have the following relation...

Inverter Capacity / (PC Power Consumption + Display Power Consumption) = Backup Time

i.e.

Y/(X + Monitor/Display Power) = Time

Y/(X + 90) = 1.75 -- eqnI

Y/(X + 35) = 3 --eqnII

solve both n u will get

Y = inverter capacity = 231W

X = PC power Consumption Excluding the monitor/display = 42W

X is very Low... even after considering the Worst CRT n the Best LCD

so CRT to LCD transition will not increase the backup time to 3hr.

...now some realtime calculation...

assuming X = 200W for ur rin...

Y/(200+90) = 1.75hr --> Y = 507W = ~500W inverter

gives

500/(200+35) = 2.12Hr --> around 2hr 7mins of backup..

that is 22mins extra after paying 12+ k for 22" LCD....

Better option is get a long lasting battery for ur inverter.
 
^^ nice effort there to sum up the exact calculations... however if you thing the monitor has got old and want to to replace it with an LCD, go ahead but there wont be much to gain in terms of amount of backup time by shifting to an LCD

Hmm... :S

I see, well may be I can right now go with LCD and in future can upgrade the inverter/battery combo :) Thanks for taking your time to make suggestions, really appreciates it.
