I have an APC Back UPS ES having an output power capacity 300Watts / 500 VA. Sometimes while listening to music on my PC, I switch OFF my Samsung 55V 15 in. monitor (Only the CPU keeps running) . Under this condition if the AC power supply is cut off and the UPS battery takes over, if the monitor is switched on just to shutdown the PC, there is a click sound in the UPS and my computer RESTARTS. Obviously this is happening due to high power consumption during startup of the monitor. My question is whether this is normal and happens with any monitor and UPS ? One more question is will this problem be solved if I get a TFT monitor ? I'd like to buy a 19 inch TFT monitor.

when the computer enter the sleep mode, it is possible that the computer remove the check mark from this output activation.
When you have multiple ouptut like a internal LCD and output on a monitor, when going into sleep then waked up, laptop reactivate the internal LCD without reactivated the secondary monitor.
you could need to go in desktop property and reactivate the secondary monitor with the check mark listed : Activate.
If you only have one monitor but still a dual output card or two separate video card same thing can happend. try to connect the monitor on the second VGA or HDMI output and see if the video goes there.
then reactivate your secondary output and make it principal.
Does also happend when your computer is connected to a UPS power and your monitor is directly on the sector. (laptop issu also)
if a brief power outage arrive then the monitor shut down (no power) and the computer continu, as there is no monitor on the output any more Windows will automatically deactivate this monitor. when power goes back, this output is no longuer providing video. I suggest putting the monitor on a UPS as well.
lever it out gently with a sharp point then apply a tiny amount of graphite eg pencil led to the outside of the button where it makes contact with the case of the machine. By lever out, i dont mean, take the button out, just release it to its normal position.
suraj2567, Get rid of that very power hungry CRT type monitor LG700E!!! It's that, or get a new 1400 to 1500 va UPS. Then you won"t be able to yank and **** the output of the UPS around anymore when you turn on your old CRT monitor!!! Also check the status of the OLD SLA battery inside the UPS you are using. If it is more than 3yrs old, it might need to be replaced due to degraded capacity to supply surge current when it is "online" during a power outage in your area...

Open Display in Control Panel.
On the Settings tab, click Advanced.
On the Monitor tab, in the Refresh Frequency list, click a new refresh rate.
To open Display, click Start, click Control Panel, click Appearance and Themes, and then click Display.
The default refresh frequency setting is 100 Hertz, although your monitor may support a higher setting. Check your manufacturer's documentation for information regarding the settings your monitor supports.
A higher refresh frequency reduces any flicker on your screen, but choosing a setting that is too high for your monitor can make your display unusable and cause damage to your hardware.
Changes to the refresh frequency affect all users that log on to the computer.
Well to narrow down the problem I would suggest first that you try to disconnect the monitor from your APC Back-UPS and just plug it directly to the wall outlet, UPS or surge protectors may cause interference at times with some electronic devices. Then if it's still here, I would recommend that you try to degauss the monitor, all CRT monitors have this option in the OSD. You should also check if there is any magnetic device near the monitor, like a speaker or phone that can cause this. If another PC is available can you try it there also, see if the problem is seen on another PC.
Finally, run the monitor self-test, to do this just leave the monitor plugged into the power outlet and disconnet the video cable, and you'll see it. If the problem is still there then most likely the monitor will have to be checked in a service center or be replaced eventually, since this would already be a hardware problem. Especially since you said the problem is apparent even in the OSD.
