Hi, I have a second monitor I would like to use along with my laptop. My second monitor only has VGA output and my computer only has HDMI. So i purchased a HDMI to VGA converter and now my second monitor won't work. I've tried messing with my resolutions and nothing has worked. Im on an HP Envy 14 Beats Edition laptop running Windows 7.

This is the product I bought: http://www.amazon.com/Cable-Matters-Plated-Premium-Adapter/dp/B00879DM56/ref=sr_1_2?ie=UTF8&qid=1361300450&sr=8-2&keywords=hdmi+to+vga

Cable won't work.

HDMI is digital and VGA is analog.

You'd have to buy a converter which converts digital signal to analog.

Broni, I read the reviews on the product before I bought it and several people were saying it would work. Also the description of the product says it will work with a monitor. So is there really nothing I can do about it?

Warning about VGA to HDMI Cables:
        

Please be wary of cables promising the impossible. VGA is an analog signal and HDMI is digital.
It is impossible     to go from one to the other without a converter.
Beware of cables like the one pictured here. You will need to use an
active VGA to HDMI converter like those described below, unless you have a specialized graphics card. Thank you.

Well what the hell lol. Why do 90% of the people who left a review said they just plugged it in and it worked? I had heard that you needed a converter and I thought the little box on the VGA end was the converter box. 

Also, on that website you linked, it says it could work if you have a specialized graphics card, so how do you find out if you have one?

Actually after re-reading I may be wrong.

I thought it was a simple cable but it says "adapter".

 

You may want to check this:

HDMI-VGA conversion may post compatibility problems under the following conditions

* The HDMI source has different refresh rate than the VGA display

* The VGA display (projector, monitor or TV) does NOT support the resolutions as output from the HDMI source (480i/480p/576i/576p/800x600/720i/720p/1280x1024/1600x1200/1080i/1080p)

* The VGA display does NOT support interlaced resolution while the HDMI source is set to 1080i, 720i, 576i or 480i

* The HDMI output of source device does NOT supply 5V/500mA power

* Does not work with Macbook Pro with retina dsiplay

You'll have to check your VGA monitor specs against these:

* The HDMI source has different refresh rate than the VGA display


* The VGA display (projector, monitor or TV) does NOT support the resolutions as output from the HDMI source (480i/480p/576i/576p/800x600/720i/720p/1280x1024/1600x1200/1080i/1080p)


* The VGA display does NOT support interlaced resolution while the HDMI source is set to 1080i, 720i, 576i or 480i

Your monitor manual or manufacturer site may give you some info.

Broni, I found the manufacturer's site on the specs of the monitor. But I'm not sure what I'm looking for. Do you think if I post a screenshot of the page, you could help me?

I'm not 100% sure but this is what I think...

Here is your monitor page: http://us.aoc.com/monitor_displays/931swl

If you click on "Support" tab you can see your monitor specs in pdf file.

 

It says:

Maximum Resolution - 1366x768x60Hz
Recommended Resolution - 1366x768@60Hz
Supported Resolutions:  640x480@60/67/72/75Hz, 720x400@70Hz, 832x624@75Hz, 800x600@56/60/72/75Hz, 1024x768@60/70//72/75Hz, 1366x768@60Hz

 

Your adapter supports:

480i/480p/576i/576p/800x600/720i/720p/1280x1024/1600x1200/1080i/1080p

 

Your monitor native resolution (1366x768) is not listed there.

 

The only common resolution between two lists is 800x600.

If you can change your monitor native resolution to 800x600 it may work.

Possibly you can do it by connecting the monitor to some other computer and using monitor buttons set the resolution to 800x600.

However your monitor seems to be widescreen while 800x600 is not so the picture will look little bit odd.

I tried setting both my laptop and the monitor to 800x600 and it didnt work. I then hooked up the monitor to a second computer and manually set it to 800x600 and it still didnt work. So is there any other options here, or should i give up? lol
