They are quick and helpful. The best thing Benfei offers with their adapters is the superior signal stability provided by the core advanced IC chip. I like that Benfei offers an month warranty on this item. It gives me confidence that the maker would stand behind their product.
It also comes at a very reasonable price and is one of the more affordable adapters available. It is the perfect companion if you want to use the latest gadgets on your legacy screens. Besides using it for presentations, you can also use this at home or in the office to extend your desktop and give you more working space, thanks to its compatibility with many devices.
Its lightweight build and small dimensions make it perfect for professionals always on the move. This adapter utilizes a smart chip to enhance the signal from digital to analog to improve its output. You can rely on the device to display multiple resolutions and aspect ratios — like p Full HD and the legacy ratio of old monitors and screens. It also has an audio output so that you can connect your speakers to its 3.
Such a premium construction also improves analog signal transmission for better viewing quality. With this adapter, you can view your videos and images on your legacy monitor at maximum sharpness and clarity.
Accordingly, this adapter has extensive compatibility. The maker has tested this device on desktops, laptops, TV sticks, the Raspberry Pi, tablets, digital cameras, video cameras, and other equipment with an HDMI port. It can also transmit a signal to TVs, monitors, projectors, and basically any display with a VGA port.
Aside from physical compatibility, it can also work with multipple resolutions, up to p, i, or p Full HD. It has a built-in smart integrated circuit to process the signal and output a sharp, crisp image.
Aside from its compatibility with low-power devices, it also has a 3. With this, you can enjoy watching on TVs without the need for an external speaker. You can utilize this product for multiple purposes due to its compatibility with common resolutions for TVs — including p, x , and p Full HD. Such a feature gives users the flexibility to set the best resolution for their contents without risking it becoming misshapen because of incompatible screen sizes and ratios.
This adapter also has a robust design — with its gold-plated connectors to resist abrasion. Plus, the product is rigid and functional, significantly enhancing signal quality. It also comes with a short four-inch cable to alleviate strain and prevent damage to the HDMI port on your device. I appreciate the well-thought-out design of this high-end adaptor. In truth, the manufacturer included Male-to-Male adapters to use the converter with both a TV stick such as Chromecast or Roku or with other larger devices like my laptop or my Apple TV.
They also included an audio cable for sound output to present for several people at one time. It also extracts the audio from the digital signal and outputs it via the 3. Such construction is an excellent choice if you want a quality product that stands the test of time. Active converters have a power port that will allow you to use them with low power ports and usually include an audio output jack.
You should know which port you have before making a purchase decision. You should also consider the ports and cables that you have available.
Another consideration would be the purpose of the adapter. Is it only for the home? Or do you intend to use it on the go? There are extra-long adapter cables designed for use when your computer is distant from your screen, and there are also light and small adapters intended for use on the go.
Choose accordingly to your needs. Lastly, read through product reviews. You should check with the manual of your device to confirm if that is the case. If so, you should acquire an active adapter to get a video signal through your VGA screen. If there are none, check the wiring to see if there are any broken wires inside. Mandatory fixed block header. Vendor and product identification. ID manufacturer name. EDID structure version and revision. Version number: 01h.
Revision number: 03h. Feature support. Features such as power management and color type. Bit 1 should be set to 1. Preferred timing mode. Indicates one supported timing that can produce best quality on-screen images. For most flat panels, the preferred timing mode is the native timing of panel.
Detailed timing 2 or display descriptor. Indicates detailed timing, or can be used as display descriptor. Two words should be used as the display descriptor, one as the monitor range limit, and one as the monitor name. Detailed timing block should precede display descriptor block. Detailed timing 3 or display descriptor. Detailed timing 4 or display descriptor. Extension block count N. Number of byte EDID extension blocks to follow. Block map or CEA extension. Change EDID 0x14[7] from 1 to 0.
Indicates analog VGA input. Modify established timing, standard timing, preferred timing, and detailed timing. Set 0x7E to No EDID extension block. Change 0x7F. Checksum has to be recalculated based on above changes. Change 0x14[7] from 0 to 1. Indicates digital input. Check standard timing information and modify if necessary bytes 0x26 to 0x Timing beyond the maximum supported by the converter and HDMI Rx must be changed to maximum timing or below.
Because VGA is an older technology, this option should be avoided unless there is no other alternative. An HDMI cable can send an audio and video signal over the same cable.
However, a VGA cable can only accept a video signal. Whenever you convert one signal to another, the signal of lesser quality always determines the final output quality. For example, VGA is an analog signal subject to interference and signal loss in transit , whereas HDMI is digital higher fidelity, no signal loss. As such, the VGA signal will be the limiting factor of the final output signal.
