This was not quite what I was expecting. It does convert VGA to HDMI, but it only accepts certain VGA resolutions.
I was hoping to use my laptop (which has 1920x1080 output on a DB-15 port) to display 1080 video on my HDTV.
The problem is that this unit only accepts the following input resolutions:
640x480 60Hz 75Hz
800x600 60Hz 75Hz
1024x768 60Hz 75Hz
1280x720 60Hz 75Hz
1280x768 60Hz 75Hz
1280x960 60Hz 75Hz
1280x1024 60Hz 75Hz
Since only 1280x768 is a widescreen format, you are basically limited to 720 format video. VGA and Audio to HDMI Converter
Product works really good!
We have IBM Lenovo T60 and T43 laptops and wanted to connect to our Panasonic 42" Plasma TV.
When we initially connected this product following the user guide given, we were not able to see anything on TV from the laptop.We even planned to return it.Then, the RMA team came up with below suggestions. The very first few steps worked and now we are happy customers.
Please find below steps provided by them:
-------------------------------------------------
-------------------------------------------------
If you wish to connect VGA output to a HDMI TV, the resolutions that will work depend on the resolutions (720/1080) that are supported by your TV.
Please try set your PC resolutions to one of the supported ones listed on the listing.
640x480 60Hz <== Try first 800x600 60Hz <== Try first 1024x768 60Hz <== Try first 1280x720 60Hz <== Try first 1280x768 60Hz 1280x960 60Hz 1280x1024 60Hz 1920 x 1200 60Hz <== Try
Below is an exmaple on how to make the adjustment:
1. Open the Control Panel.
2. Double Click "Display"
3. Click the Settings Tab
4. Click the Advanced Button
5. Click the Adapter Tab
6. Finally, click List All Modes
7. Scroll to the very top and select the smallest resolution(In my case, it is 640x480, True Color, 32 Bit, 60 Hertz).
8. Click Apply *WINDOWS XP
(*) NOTE 1: Whatever resolution goes in this converter, goes out as it does not upconvert or down convert the signal. Any aspect ratio control is done from your source device or your HDTV. A 4X3 input comes out as a 4X3 output, same with a 16X9. See the above resolutions that this device supports.
(*) NOTE 2: This VGA to HDMI Adapter is not a scaler or scan converter. This means that the resolution of the video signal at the HDMI output is the same as the input signal.
(*) NOTE 3: Most HDMI enabled displays do not support the full complement of PC resolutions and are only designed to handle HDTV input formats of 480i or 480p @ 60 Hz, 576i or 576p @ 50 Hz, 720p @ 60 Hz, or 1080i @ 60 Hz. This means that if you set your PC at a resolution of 1024x768 (XGA), your display may not display the HDMI image. Try 1024 X 768 first.
In this case you have to set your PC's resolution to either 640x480@60 (VGA interpreted as 480p), 800x600@50 (SVGA interpreted as 576p), or 1280x720@60 (WXGA interpreted as 720p).
(*) NOTE 4: Your video card has to be able to output a resolution your TV supports in order to get a Pixel for Pixel image. So if the native resolution of your TV is 1366x768, you are going to get the best picture if you can

get your video card to output 1366x768. Thats what makes it 1:1...or actually 1366:1366. Some video cards can't output HD resolutions so check your manual.
(*) NOTE 5: Please try the following resolutions: 1280x720 or 1366x768 ( 1280x720 is preferred and will most likely work ). If you don`t have the resolutions listed above, please download the latest driver for your video card and it should have either 1280x720 or 720p ( under HDTV resolutions ).
(*) NOTE 6: Many consumer HDTV's suffer from overscan or cutting off of screen information that may make navigation difficult.
(*) NOTE 7: The VGA to HDMI Adapter offers the truest conversion available between a PC and an HDTV. The clarity of the HDTV display is directly related to how close the VGA out is in dimensions and pixels to the HDTV format.
(*) NOTE 8: Try it on a desktop computer to see if it can work. Try 1024 X 768 first.
(*) NOTE 9: For your laptop, please try the below operation. Right click on the laptop monitor, Choose the "Properties" Click "Settings", Tick "Expand the windows desktop to the monitor", Click "Application" to save the setting.
Then you can try clicking the "Advanced Setting" under the "Expand the windows desktop to the monitor" and set it (On this set, please check the items in details and set the one suitable for you).
(*) NOTE 10: 640x480 is EXACTLY the same as 480p, so a 480p HDTV display will be that of a true monitor in clarity. 1024x768 is closest to 720p and will generally look best on that HDTV resolution. Performance will vary slightly depending upon the HDTV.
The above limitations can be overcome providing that your PC's video card can support special resolutions, and you are able to properly configure the output. One resolution that will require no special modification is 640x480 (480p) @ 60Hz which should work on virtually all HD-Ready TV.
