LG Monitor Unable to Correctly Detect VGA Input

Good afternoon,

I have a situation where our 60" LG monitor can detect VGA input to display, but it will not allow the toggle that displays both on the monitor and the PC. The PC works fine with a projector. Any ideas?

Thanks,

Stan

The problem is not the monitor.To be able to correctly set a dual display mode you need to configure you video card to do so. This is accomplished in your video card's control panel. There are various modes:
Clone: it simply clone the screen you'll have the same output on both monitors.
Extend: this will extend your desktop and make it one big screen.
theres another mode to show video only on one screen while the other display regular desktop activities you'll have to experiment.
the procedures for doing this varies depending on you video card: ati, nvidia, or Intel.

Model dx4300. Why does monitor indicate no signal input?


This machine has both VGA and HDMI outputs. Depending upon your monitor, you have one of the two cabled up to it. Some monitors will auto-detect which input is active, but others do not. Check the monitor and ensure that if is has dual inputs (VGA/DVI) (VGA/HDMI), that you have the correct input source selected. This is usually done from the buttons on the monitor itself.

Check signal cable


This messsage is usually displayed when the Monitor is unable to detect any input signal this can be due to the faulty cables (VGA/HDMI). I suggest you to try to connect a different cable and check if the monitor works. If not then update your video drivers.

There is a lack of communication between the monitor and video card. Try reseating if add-on video card. Make sure monitor is set to correct input, like VGA (analog), DVI, HDMI, or Display Port. Try testing with another monitor.

No signal detection on all the input ports from the PCDell lcd display 27


Well if you have a VGA monitor it definitely wouldn't go into any port but the VGA port.

Have you looked into the Bios or System Setup to make sure nothing in there regarding the VGA port is off?

I think your problem is either the Monitor is bad or the Video Card in the computer is bad. Make sure the vga cable is pushed in good in the computers vga port and that it is in good in the back of the monitor. Also you can look at the end that goes into the computer and see if any of the pin or prongs are bent. If so, that could be the problem. Don't get alarmed if it looks like some of the pins or prongs are missing, that's just the way it is made.

Does your monitor give you a message on the screen that says "No Input Signal"? If so that's a sure sign that maybe the Video Card in the computer is bad or is not pushed in all the way inside the computer if it resides in one of the slots. Try another monitor on the computer and if it gets the No Input Signal message then the video card is definitely bad.

To see if the Monitor is the problem just try it on another computer. If it fails on another computer, then you know the monitor is bad.

I have a Samsung SensR470 laptop and i have linked up the VGA, audio, and power cables but the monitor is not showing anything. when i turn it on, it just goes into sleep mode or otherwise shows the...


its because you failed to read the Samsung manual on your PC
go there and read, it has HOT key , all laptops have a hot key
Fn key that turns on the external display VGA jack.
on rear of this SAMSUNG.

SLEEP MEANS THE PC IS NOT SENDING THE HORZ AND VERTICAL, SYNC SIGNALS. AT ALL.
THAT MEANS WHAT>?
It means the PC, VGA jack is turned off.
bad cable
bad monitor.
The PC can also be bad VGA chips, or worse,.

your first failing here is not saying why you are using VGA jack
is the Laptop screen dead too> (my other shoe falls off)
dang that be nice to know , no?
or like we do run that VGA to a projector? for say doing power point presentations, (done many before retired)
RTM, the manual is free to read any time of day, 24/7
each PC maker uses there own rules here, its there call
there design and their rules.
my HP its, Fn+F4, (toggle:, internal, external ,both or auto)
but yours is Samsung, ask them. or learn to use google?

The 1525has a a hdmi port which you can plug a hdmi cord into. This may not support the audio. the tv and pc should detect the new monitor automatically or you may have to toggle it by hitting F4 key.

LG Flatron L2010P monitor. Says no input signal with the monitor plugged into the PC. I know the cable and PC are good as they work with my other monitor. Thanks for any help!!


Make sure the correct input is selected. This monitor has both analog (VGA) and digital (DVI) inputs, and it may not be automatically detecting the input you're using. If the proper input is selected and the monitor still says there isn't any input signal, about the only option is to replace the monitor or try to find a replacement signal board from an online source. Most repairs need specialized tools to diagnose and then change the bad parts.
