Cable Matters Unidirectional HDMI to VGA Adapter, VGA to HDMI Converter, Black

[Update 20 Mar 2015] - I am changing this rating to 5 stars. I hooked this up to my OTA digital tuner and it worked just fine. It must be some incompatibility with ROKU. As such, I don't feel it's fair to disparage this product because ROKU didn't work correctly. The company Cable Matters replied promptly to my original comment with a fair and helpful reply, so I am happy with th device. Just beware that the ROKU HD may not play well with this (in my experience).I am giving this two stars unless I figure this out. I bought this to hook up a ROKU box to my projector. I did not like the picture quality of Composite Video out. I have my HDMI cable running from the ROKU to the Cable Matters converter box, then from the box to my VGA projector. When I go to ROKU, all the menu screens work find, including up to the "Play now" on any episode of any Netflix, Plex, CBS, etc channel. It even displays "loading now". However, as soon as the episode is loaded, the screen blanks. I have a Viewtv At-163 ATSC Digital TV Converter Box and Media Player w/ Recording PVR Function / HDMI Out / Coaxial Out / Composite Out / USB Input that is connected to the projector via component video through VGA adapter and works flawlessly in 480P, 720p, and 1080p so I know my projector can handle the different resolutions. I have tried the converter with and without the micro-usb cable, so I do not know what else to try. Hopefully the manufacturer will have a suggestion, and I wont have wasted a SECOND purchase on trying to get HDMI out of my ROKU to projector.

Works but didn’t work for my use case. I needed to connect my projector to my Apple TV. Due to Apple tv’s copyright protections on analog signals or something, you need a really high quality one to meet these requirements. This one didn’t work for that but the Belkin one did!

Got this to play Google Play movies from a Chromebook to an older VGA Projector. Worked like a charm with no fussing around. Once the Chromebook HDMI out was plugged into this adaptor, and the adaptor plugged into the VGA In on the projector - it just worked. The Chromebook instantly saw the second display, set the resolution to the highest supported by the projector and we were off. Picture quality was very good, as good as VGA allows.The only issue is Audio. HDMI sends audio with the video signal, but VGA does not. This created a minor issue, as the Chromebook thought audio was playing over HDMI - obviously it wasn't. This adaptor does not have an audio out, but that was not an issue. We just set the Chromebook audio out to be a set of Bluetooth speakers and we were in business - big projected picture and great sound. Awesome way to watch a movie.BTW: While I mention Chromebook above, I did the same setup from a Windows Laptop and it had the same issue with audio, and the same solution. So the behavior is the same on notebooks other than the Chromebook I talk about above. The only difference, the Chromebook had enough power via HDMI to power the adaptor - the Windows laptop did not. On Windows, I plugged the included micro-USB cable in to give it more power. The adaptor came with the USB cable for this issue, nice touch.Quality: good. Movie quality looked very good. When displaying static content, like excel spreadsheets or PowerPoint presentations the low resolution of the VGA projector was more visible but the quality was still fine - crisp, sharp and vivid colors. All good.

Bought this HDMI-to-VGA adapter (which is shipped with an included USB power cable) for pairing a new HP Chromebox (CB1-014) for use with a very old LCD. Works great - simple plug-and-play. Allows use of an old 15pin D-sub VGA cable to the LCD monitor. (Note: While HDMI cables provide sound, VGA does not. Thus a person would need a separate 3.5mm audio cable to provide sound to the speakers being used. Since i already had said 3.5mm stereo cable for providing sound, there was nothing else for me to purchase.)Note: The Chromebox clearly labels that the front two ports as USB Power ports (noting that they provide both power and data connections.) Be certain to power this HDMI-to-VGA adapter with the PROVIDED power cable (USB-A male to micro-USB-B male power cable.) Using that power cable connected with a simple USB data port might not provide enough power - idk really - since first i do not know the required min power to drive this this HDMI-to-VGA adapter. I am assuming that any negative posts about this item are related to ppl not using the PROVIDED power cable or possibly connecting that cable to a data-only USB port - but really i am guessing here. (Note: The USB power cable plugs into a USB-A power port and also a USB micro-B port on the block-shaped part of this HDMI-to-VGA adapter.)

Works great! Now I have dual monitors! Easy to connect. Don't forget to go into display settings - the part that took the longest to set up!

I got this adapter to connect a BlueRay player to my older projector. I plugged it in and it didn't work, "no signal detected." From the many positive reviews I have to assume that this is a good product, but it didn't work when I wanted it to. My understanding of my problem is that the HDMI source has to be powered (5V/500mA, see "Compatibility" in the specifications), and most dedicated media players aren't powered. That's why people with laptops and tablets love this cable, and people with DVD and BlueRay players say it's junk. If you want to use your new BlueRay player with your old VGA TV/monitor/projector you'll need a powered converter to convert and HDMI signal to VGA. And be sure to get HDMI ---> VGA. There are lots of converters to go from VGA ---> HDMI, and they won't work either. Look closely before buying one from the Brazillian rainforest site (I looked, they're all junk). I had good luck on the freshly laid unhatched bird baby website.
