Switch vga to hdmi. HDMI VGA Adapter - Features and Applications
AT narazі Connecting a computer with a VGA output (there is no DVI or HDMI outputs) to a video card to display information (TV, monitor, projector) with an HDMI input is only possible due to signal conversion (converter) jamming.
The same situation with the connection of new attachments to the signal jack (DVD player, Blue-Ray player, satellite receiver) With the HDMI output to the extension for displaying information, we will change the sprat of fate. Sound the presence of VGA (RGBHV signal) or 3RCA (component signal) on them.
It’s often possible to finish the cicav on the cable using the “VGA-HDMI cable” or the “VGA-HDMI adapter”. , the VGA-HDMI adapter is to blame. You can twist it, but the whole "garland" will not work.
It is understandable why in these situations the problem can be overcome only for the help of changing signals.
- Reason #1: Different nature of VGA and HDMI signals.
VGA signal is analog and HDMI is digital.
VGA (Video Graphics Array) is an analog video signal format, split for displaying images on a computer monitor. Basically, a VGA signal is an RGBHV component signal (RGB signal + horizontal sync + vertical sync).
DVI (Digital Visual Interface) - interactive digital video. Standard for digital graphic interface, a kind of wide rose rosette. Signals RGB in the new, to the analog signal VGA, digital, and are transmitted by differential levels. The interface is designed to transmit data from a graphical information source, for example, a computer, a video image capture card, a decoder cable television and so on, to receivers, for example, to a digital monitor, plasma screen, video projector, etc. The same signals are transmitted through the DVI interface. The 24-pin DVI-D connector is used for transmitting only digital images, and the signals of the "old" analog VGA are also transmitted through the auxiliary contacts of the 29-pin DVI-I connector. Through high speed transmission of digital data, DVI signals are sensitive up to the length of the cable.
HDMI (High-Definition Multimedia Interface) - high-definition multimedia interface, mostly digital interface, intended for transmission of uncompressed video streams and rich-channel audio signals. HDMI is backwards compatible with DVI and supports all computers allowing up to UXGA, SDTV and HDTV up to 1080p, as well as 8-channel digital audio - all over a single cable. HDMI is the most popular interface in the emerging market for video conferencing other outbuildings, Such as video set-top boxes, DVD players, game consoles and receivers, with all kinds of digital HDTV TVs.
Polypsheny protection against unauthorized copying is another HDMI problem. The HDMI standard secures an even higher level of protection from unauthorized copying that pleases the richest content providers. Most devices that implement HDMI technology on the current market support HDCP (HIGH-BANDWIDTH CONTENT PROTECTION - protection of data against unauthorized copying), but it is incomprehensible for the connoisseurs. In fact, the skin attachment included on the signal path with HDCP encryption can be combined with HDCP, so that the signal is transmitted from the dzherel to the display.
In this order, the main features of the HDMI interface in the DVI interface are:
1) Ability to transmit rich-channel sound.
2) HDCP Support (High Permission Video Data Protection against Unauthorized Copying).
3) Miniature rose.
- Reason #2: HDCP presence in HDMI signal.
In case you need to convert the HDMI signal, taking from the Blue-Ray program of either the satellite receiver to the VGA signal or the component signal, you may find out the situation, which in case of different required and reference conversion of the signal, there will be no image on the display. Most of the inputs are connected via HDCP, so the encrypted signal is taken from the HDMI output of the dzherel signal, and after the signal is converted by the HDMI converter -\u003e VGA is fed to the VGA input of the extension, so the VGA interface does not support HDCP . Tsya problem virishuєtsya behind the help of special outbuildings. When converting a VGA signal to an HDMI signal, this problem is daily.
relative on New river pleased myself with a widescreen "reasonable" Philips TV. I choose TV. In the midst of an impersonal favor, when choosing a model, it was possible to connect yoga to a netbook in the capacity of a monitor. And here I am, zvikly, that the HDMI port is on all modern portable computers, giving a blunder. Only analog VGA output is displayed on the netbook. TVs had no VGA, no DVI ports. What do you think, to correct your mistake, I had a chance to look for an adapter from VGA to HDMI. Crossovers, yakі proponuvalsya offline, boules dosit roads. Crimean sellers did not guarantee 100% work in a particular case. Tom had a chance to shukati an adapter to the Internet.
At cіy situationії zvichayno nі about yak in front of the testuvannі not bulo b moving, і in razі not pracyuvati less check tedious listing with the seller і farther away from the goods to the fatherland. Since it was possible to take a VGA to HDMI adapter in the chinabuye.com online store without a cost of looking around, I didn’t bother to speed up.
The adapter comes in a cardboard box with the end. 
In the wake of this wonderful side, I will add a short summary of the possibilities.

testing:
To rewire the robotic adapter, I had to add a VGA and HDMI cable, which were not included in the kit. The axis in the assembly looks like this: 
USB-cable for dodatkovogo kharchuvannya buv p_dklyucheniya to the netbook. Without supplementary eating, the adapter does not work.
As it was said in the instructions, the transitional worker earned without any additional damage to the body. To finish the Bulo just connect all the cables. You can see the result in the photo below: 
On the butt, the image on the TV is displayed from a separate building 720p using the screen cloning method. More razdіlna zdatnіst protest not far away, so that's the maximum, which can be seen on the video card of the netbook on the display.
I didn’t test the Audi, so, according to the order, there was no need for it.

The interpreter reaffirms his confession. Spend your wealth, artifacts, etc. the speeches were not marked in the selection process. I have cleared up my mistake in front of my relative and can boldly recommend this adapter for connecting netbooks and other attachments with a VGA output to a TV via HDMI.

Such cables, which are used for vikonannya raznyh z'ednan, toil on their own ends of song for recognized connectors. The skin rose to its own parametric characteristic, as it vouches for the quality of the broadcast signal. In this publication, it is recommended to look at the technical parameters of the vga hdmi cable and the main mind correct selection high-speed transmission.

HDMI to VGA adapter
First, it is necessary to understand for what it is necessary hdmi vga cable and recognition of yogo roses, and yaki functions of the stink of the stench. VGA is an analog fifteen-pin interface for connecting monitors to video equipment, mainly to a personal computer. The principle of Yoga Die is characterized by the transmission of only an image with the presence of sound. HDMI, the digital universal multimedia interface, for the help of which audio and video content is transmitted, as well as high-quality signals. To combine these adapters into one lance, you will need a folding accessory, and a signal converter itself.
Hdmi - vga connection diagram:
- z'ednuvalny hdmi vga cable. The cable can be fixed only if the monitor or TV has the function of recognizing and registering pulses in analog format. So the cable itself does not break the signal by itself.
hdmi vga cable serve for connecting a viprominuvach with an analog output to a TV set, or a PC monitor
- On the sign below the readings there is an adapter, which is the function of converting the signal. In this design, a miniature converter is transmitted, and a monitor and vibrator signal are connected to it.
- On the attacking sign, there is an attached security connection with an HDMI port and an adapter for an analog format, which can be individually connected with a vibrating impulse.
- HDMI-converter, the whole accessory for connecting, converting, converting HDMI signal to other devices, such as projectors, DVDs, TVs, HD-players, personal computers.
HDMI converter for signal conversion
How to use hdmi vga cable
The main principle of the adapter's work lies in the fact that it is possible to transform audio and video signals of a continuous analog format into a digital discrete signal. Until then, the process of converting directly into the sound signal strength.
The power supply of the vga to hdmi adapter is to fit into the different wires:
- V_d fringing lansyug vga to hdmi;
- view droti usb vga to hdmi.
connection specificity
In order for the viscount to connect the signal and the TV to the converter, it is necessary for the mother to use the wire for the personal skin accessory and, of course, the converter itself.
1.
Source adapter for additional audio is connected to the converter (video content and audio support);
2.
The usb hdmi plug connects to the TV output.
- Video content and accompanying sound are transformed into auto-mode, so there is no need for additional regulation.
- Well, if the monitor has a signal conversion module, then it is also necessary to simply insert the hdmi vga remotely, and the signal conversion will be carried out in the most built-in extension.
Correct choice of hdmi vga adapter
Mayzhe all attach the role of adapters, converting the sound impulse is not the same. On the right, in the fact that a leather-worker, when prepared, will add a stagnant moisture technology, which is tested by other companies. When buying such an attachment in a store, it is respectful to look at the instructions with a cis-passport to attach it, to determine the parameters and characteristics of the operation of this device.
Crimea sane looking constructions and yogo technical warehouse, do not leave the space to determine the quality, borrow the firm-varner. Only a company's collection of possessions can guarantee reliability and safety in work. Beware of misinformation and unknown vibrators shouting mistrust.
At our hour, an HDMI VGA adapter is also needed, if you want to connect your laptop or an external PC, on which one you can only use VGA, to a TV or another add-on, on which one only HDMI.
Really, regardless of the apparent simplicity of this diet, everything is richer, more foldable, lower at first glance. Looking ahead, let's say that you know a simple cable that will transfer from HDMI to VGA and on the other hand, it's superbly foldable.
To understand why we say so, let's look at the very nature of the two looked at signals - HDMI and VGA.
Features HDMI and VGA
The main feature of these two signals is that HDMI is a digital signal, and VGA is an analog signal. Without going too much into details, let's say that the difference looks exactly like it is shown in little No. 1.
Wanting all systems, and not only, engineers are well aware of such an understanding, like an ADC, that is an analog-to-digital converter and a DAC, that is a digital-to-analogue converter.
Therefore, in theory, the difficulties in converting such a signal in the current world are not to blame.
Ale is all right in that VGA is the format, we accept it exclusively for displaying images on a computer monitor. HDMI is more functional and supports the work itself various outbuildings.
Ale s tsim something i pov'yazana main problem. In HDMI, it's as clear as HDCP. I won't go into too much detail. Let's say it's less than those that need to be done with a collapsible system for a signal to be read by outsiders.
It is necessary to be alert, as a signal that there will be "enemies" - the stench simply cannot be read without using the same HDCP technology.
To that, just to make a great adapter, which will be a wire with an HDMI tip on one end and VGA on the other, nothing will be seen. Koristuvach can connect such a cable, but as a result only a black screen will turn on.
advance: Don't get scammed! Do not buy wrong adaptersHDMIon theVGAAnd on the other hand, they are just a cable with two lugs.
