Vga To Hdmi
People seem to be buying this item expecting it to be VGA to HDMI, or bi-directional. This was made to send the video from your HDMI source, to your VGA display. If you're trying to convert a VGA signal to an HDMI signal, you need to convert and get a proper cable.. much more expensive. ..but stop marking this thing poorly because you don't know what you're buying. It's not a bad product, it's just getting bad reviews from people who can't do research or for that matter, read. HDMI to VGA HD15 (Male) Cable
The product description states, "This HDMI to VGA HD15 (Male) connects your HDMI-equipped device, HDTV (NOT FROM COMPUTER OR LAPTOP) to your monitor. The HDMI-equipped devices include...Playstation system"
Well, I connected this cable from my PS3 (in the above list) to my VGA input projection monitor (ACER XD1150) and the projector does not recongnize the signal. Based on the description I can think of no reason why this wouldn't work. The ACER takes the same exact input and works the same way as a computer monitor. The PS3 is an approved device. Yet, the signal is not recognized. My only conclusion is that the cord fails to convert the signal from HDMI to VGA making it useless.
The top rated review for this says it allows hdmi to vga but not vga to hdmi. After purchasing this to go from my hdmi output cable box to a vga flat screen monitor, it does not work. This product does not do what the top rated reviewer says it does.
An HDMI cable is purely digital (1's and 0's) while VGA is completely analog (waves). You will most likely be wasting your time purchasing this product unless your device has some magical way of outputting analog signals through its HDMI port. The product still gets 2 starts for being honest and saying don't try to connect your VGA port on your desktop or laptop computer to an HDMI port on your display, but I seriously doubt that it will work in any situation.
The idea solution to someone looking for a way to do this is if they had a an HDMI cable attached to your device and a signal converter (these are currently north of $100 as of the time of this review, closer to $170) and then a VGA cable going out from that to your monitor, similarly this is how you could go from your computer to converter box to HDMI to TV.
If you're wondering "Well, DVI is a digital interface and there are cables that go from VGA to DVI and it works perfectly fine!" its because the DVI interface actually has half analog pins (DVI-A) and the other half is digital, which is how it is capable of taking VGA signals. HDMI cables do not have any compensation for this conversion at all.
I was also looking around and this cable seemed to be exactly what I was looking for, it went from an HDMI input to a VGA output... Surprisingly, it even looks like a well-made cable, but unfortunately, doesn't work at all...
I purchased this to connect HDMI equipment to an EPSON projector that I have, which unfortunately doesn't have an HDMI input on it, only a VGA. According to the description of this cable, that is exactly what it is supposed to be used for, but it DOES NOT WORK!
What everyone needs to understand here is that you need to research before you buy. This product is not meant to take a digitanl signal and allow you to connect to an analog display, or vica versa. This cable does not do a digital to analog, or analog to digital, converion. Most HDMI devices are going to be digital, while most VGA devices are going to be analog. You cannot connect the two with a cable. You have to actually convert the signal. This cable is meant for the very few devices that can actually output analog from the HDMI connector. This is very rare and you should pretty much always assume your HDMI connection cannot support analog, and your VGA connection cannot support digital.
Do some research on your devices. The manual should tell you what is supported on each connector.
If you are trying to use this to connect your laptop or pc to your tv, and your only output is a VGA port, this will not work! VGA is an analog signal, and HDMI is digital. You cannot convert analog to digital with a cable- you need to purchase a converter to do this. There are several on here for about $40, and some that range up to $300 or more. I do not know if the $40 ones work, but I can tell you the $6 cable certainly does not! I don't know if this can be used to connect an HDMI out to a VGA in, so certainly do your research before buying this. It doesn't cost enough to worry about sending it back, but if we had spent much more on this, I would be returning it today.
I bought this cable to connect my new Dell Mini 1010, which only has HDMI out, to older projectors with only RGB/VGA/component/S-video in. It does not work. I attempted to get a signal through my RBG/VGA-in on both my Sony Bravia HDTV and older projector but found no success. (Note: the Mini did display on the HDTV when going HDMI out to HDMI in, using a different cable).'
