Connecting second monitor

I am connecting a second monitor directly to my sceptre x9g monitor. I have changed the settings to reflect second monitor. The second monitor is displayed in device manager. Still am not getting anything except "check signal cable" displayed on second monitor. I do not know how to change monitor port if that is required. Help!

Re: Connecting second monitor

Not sure If I am understanding this correctly, you are trying to connect a monitor to a monitor? I have never heard of that before. As far as I know you need a video card that has dual output to use dual monitors. I am not saying you can't do what I think you are saying but I never heard of that before. Also on a side note depending on the resolution and amount of colors your operating system is set on, you need a video card strong enough to drive both monitors.

I recently acquired a sceptre x9g Naga V monitor which has developed a problem. It produces a wonderful image which may last 5 min or 5 sec, then goes black. If I turn it off or unplug the monitor the...

It may have dying power supply due to bad DC filter caps like the 17" version.

If you are going to DIY and already try the monitor with another PC, and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for:
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Or just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.

Occasionally, when I turn on my computer, my Sceptre X9G-NagaIV (Black) 19" LCD Monitor screen has a dark pinkish hue to it. Adjusting the monitor's controls don't help. If I unplug the monitor from the...

This could be as simple as the video cable isn't connecting securely. You could try replacing the cable or screwing it tighter. We recently had a red tint on an external monitor for a laptop because the cable was loose; since the laptop moved regularly, screwing the connector to the port on the machine wasn't a convenient solution. The other reasons for an odd tint like that is the video card or the monitor starting to fail. Attaching the monitor to a different computer and seeing if the problem repeats will check if it is the monitor and not the video of the computer.

I hope this helps.

You have a power supply that is about to die. If you can solder you should be able to repair the monitor yourself. The problem is caused by blown capacitors on the power board. Go to our web site at : We have pictures of what to look for. Open your monitor and look at the power supply board for any blown capacitors, replace all that you find. The replacement parts can be ordered from several places on the internet or we can supply them for you. The replacement parts will need to be high temp and will be marked 105c. The values you need to get will be marked on the sides of the ones you take out but will be something like 220uf, 470uf, or 1000uf etc. and then a voltage rating. When you install the new ones be sure to insert them with the polarity stripe going the same direction as the old ones come out. If you don't want to do the repair yourself we do offer a repair service for $35 plus return shipping. If you have any questions just let us know

I hope this helps if so please rate our solution.
