Windows 7: Dual monitor setup hdmi to vga on 2nd monitor shows nothing

Dual monitor setup hdmi to vga on 2nd monitor shows nothing

I have the 2nd setup through a vga to hdmi cable but it just sits there black with "check signal cable."

2nd monitor is an lg2241

Tried:

- multiple re-boots
- downloaded a driver from LG but don't see that it did any kind of install. Double clicking it's zip file opened it and clicking on the three files did nothing but open gibberish code.
- at screen resolution I see multiple displays and I have it set on extended.
- Clicked detect and identify
- #2 says display device on vga
- tried unplugging and reconnecting the cable (hdmi to vga)

I'm lost. SOS!

lol!

Thx,
Dave

Dave welcome to the Seven Forums.

That cable won't work unless the VGA port on the computer/laptop supports digital (highly unlikely), as VGA is an analogue signal and HDMI is digital. To get it to work you would need some kind of converter not an adapter, which that cable essentially is.

Assuming this is your monitor,

LG E2241V-BN: 22" Full HD LED LCD Monitor | LG USA

is says it has a VGA port on it. If it does then just use a plain old VGA cable.

"it says it has a VGA port on it. If it does then just use a plain old VGA cable."


Using that vga port for the 1st monitor is using it. It's a View sonic 1080p and all I see is vga there.

So you're suggesting a vga to hdmi converter?
1080p HDMI Male to VGA Female Video Converter Adapter Cable for PC DVD HDTV New | eBay

Would that do the trick?

Many thanks,
Dave

That should do it. I would be more inclined to go with something like this (feel free to look for cheaper, etc),

SYBA SD-ADA31040 Plug & Play VGA to HDMI Converter with Audio Support, 1920 x 1080 Resolution Supported - Newegg.ca

that uses a USB connection to power it. Reason for saying that is I have seen numerous reports of HDMI ports not providing enough power for the self-powered converts to work. Just eliminates a possible need to return and order another.

Hmm, ok so I would use the usb to power it and then could I use the current cable I have - hdmi which was going into my pc to vga to the monitor. So I wouldn't be using the vga of 3.5mm ends on that cable.

Or would I need to buy a new vga to vga cable and use it with this converter?

I have to go about 10-13' so the supplied 4 or 6' isn't long enough. I currently have the vga to hdmi cable that is long enough. Hoping to use it with this converter.

Thanks again.

Maybe try putting an HDMI-to-VGA adapter on the end of that cable so you have VGA at both ends.

Some monitors have a button to select input mode (I know mine does). I guess it should auto-select but you never know.

Sorry to prolong;

The newegg description reads:

"This is an integrated VGA & Audio to HDMI converter. It will convert a VGA source to a HDMI display"

Same as on another cable I found:

"Important Note: converter is NOT bi-directional. It only converts from VGA to HDMI."

I believe I'm looking to do the opposite. I have monitor #1 going out of my only current vga. So I'm using the hdmi port to hopefully connect monitor #2. Problem is both monitors are both vga input only.

So I need something to go out of the hdmi (and possibly have a usb power to help power it if needed) and into the vga of my #2 monitor.

2 vga monitor's and only 1 vga output on the pc.

So I would think I need to go out of the hdmi into some sort of hdmi to vga converter (rather than vga to hdmi converter which I am assuming these are) and use some sort of adapter to go into my vga monitor.

Sorry about that, you're correct in needing one going the other way. Something like this one,

Amazon.com: Generic HDMI Input to VGA Adapter Converter For PC Laptop NoteBook HD DVD: Electronics

should do.

Why are you using VGA at all, can you give us a shot of the io shield of the back of the computer, or at least a link to the motherboard or a link to the PC, your description says nothing, can`t help you unless you give the details.

Example of io shot:
