HDMI and VGA are two interface standards for video signals. While the two are different, the quality of either of them is dependent on the source of the signal rather than the interface. Both are capable of carrying high definition signals. Indeed, VGA is used for higher resolutions that HDMI currently handles.
HDMI is digital while VGA is analog. Although HDMI cables have restriction on length, the image quality will not degrade over a long cable run (subject to the maximum cable lengths). VGA signals can become degraded over long distances, showing up as smeared vertical edges on the display.
HDMI carries audio data as well as video, so one cable does the job of a VGA and audio cable combined.
It is worth noting that DVI is the digital standard for computer displays. DVI is fully compatible with HDMI video but it does not carry audio so it is a much closer equivalent to VGA.
HDMI is becoming the standard for all commercial HD video content. It is getting almost impossible to purchase equipment that outputs any form of HD video on VGA or on analog component signals.
Unfortunately VGA to HDMI cables are kind of a scam. The problem is VGA is an analog signal and HDMI is a digital signal. A cable is not capable of converting something from analog to digital or the other way around. In order to connect between a VGA and an HDMI connection you must use an active converter that will convert from one format to another. These converters are going to be considerably more expensive than just a cable, but they'll actually get the job done. These converters run between $60-$300+ depending on the capabilities of the converter.
The 945 should be able to utilize a VGA to HDMI converter, no problem.
HDMI cables are used as digital video and data links between video sources and televisions. HDMI is compatible with DVI interfaces so if the laptop has a DVI output, a DVI to HDMI cable can be used. If the laptop does not have HDMI or DVI, then there is no way to connect the VGA output to an HDMI input. There are several USB based video displays that can be purchased to connect to the laptop. The display can be used as a copy of the internal screen or it can extend the desktop across both screens. Select a display port that has either DVI or HDMI outputs.
There are multiple converters and cables that are compatible with both HDMI and VGA, which is some sort of an adapter to an adapter. I do not know how well these products work together.
HDMI is the only digital input in the group you specified. VGA carries RGB signals along with synchronization information, so VGA is really RGB. RGB is analog. HDMI sends video information encoded in data frames. That is -- it is sent in numbers. VGA/RGB sends the same information using careful timing and voltage levels, so it's very much more like analog sound than anything else.
Dvi would be better than vga. DVI was the front runner for HDMI. VGA has been around for quite a while as far as technology goes.
HDMI and VGA are both video interfaces capable of carrying computer display data to a monitor. HDMI is digital, VGA is analog. HDMI is NOT inherently better than VGA. Each will support a wide range of screen resolutions and it is the screen resolution and color depth that affect the image quality rather than the interface used. Choose a graphics card that supports the resolution you need and make sure it has the output you need to connect to your monitor.
No, This is from VGA to HDMI and not the other way around.
VGA to HDMI is a complicated process and can be helped with a cord that transfers VGA to HDMI and can be found at most major stores in your area such as Best Buy.
Yes they work well. There are many types but all have the same basic operation of converting the analog video stream of VGA into a digital equivalent. There is a myth that HDMI is better than other signal formats. Be assured that this is absolutely not true. An HDMI signal generated from a VGA signal will not be any better than the original VGA signal. HDMI is simply a digital signal format and carries a signal in the same way that VGA or any other interface carries a signal. So, use a VGA to HDMI converter if you need to connect it to a display that only has and HDMI input. Don't use one if there is an existing VGA input available as it won't make the picture any better.
A hdmi to vga is an adapter that you can plug into your laptop. You plug in one end to your hdmi outport, and the other end is a vga port. Its applications are connecting a television to a computer or laptop monitor.
The average price of a VGA to HDMI cable may range from $4.00 to about $50.00 depending on the type selected and brand. Amazon is a good place to buy VGA to HDMI cables for cheap.

You can go online or to any electronic store to buy a hdmi to vga cable. This is a cable that has the hdmi adapter on one end and the vga adapter on the other end. This way you can convert a hdmi device into a vga device.
When you use a VGA cable coming out of the monitor, the monitor is giving out an analog signal through the VGA connection. For the monitor to give out a digital signal, you need a DVI or HDMI cable. The VGA to HDMI cord just converts the analog signal into a digital signal so it's not completely useless, however the quality will not be as good as an HDMI to HDMI or DVI to DVI or HDMI to DVI
There are a couple ways to connect VGA to HDMI, the easiest are either using a converter or a cable. What you choose should depend on your needs. A converter is a box that allows you to connect your VGA component and your HDMI component into a box and converts the signal. The cable connects on one end to your VGA component and the other end connects to your HDMI component and can vary in length.
Use a VGA cord or a VGA to HDMI adaptor connected to the laptop.
