What is the different for VGA to HDMI converter and HDMI to VGA converter?

The demand for VGA to HDMI converters is increasing, and the new VGA to HDMI converter. It can convert the input VGA analog video signal into a complete HDMI signal output. For example, the VGA output of the graphics card can be converted by this converter and connected to a full-HD (1080P) large-screen TV. The VGA to HDMI converter is processed by Scaler when processing VGA signals, and the resolution can be up to 1920*1080@60Hz.
The VGA interface is a D-type interface that belongs to the analog signal. There are 15 pinholes on it, divided into three rows, five in each row. Among them, in addition to two NC (Not Connect) signals, three display data buses, and five GND signals, three RGB color component signals and two scan sync signals HSYNC and VSYNC pins are important. The color component of the VGA interface uses the RS343 level standard. The peak-to-peak voltage of the RS343 level standard is 1V.
The VGA interface is the most widely used interface type on graphics cards, and most graphics cards have this type of interface.
Common VGA interface devices are: computer graphics, monitor, VGA matrix, VGA splitter, VGA switcher, RGBHV matrix. RGBHV matrix switcher, VGA display, VGA capture card, etc.

HDMI

HDMI, high-definition multimedia interface (English: High Definition Multimedia
Interface) is an all-digital image and sound transmission interface, which is a digital signal, which can be used in set-top boxes, DVD players, personal computers, video game instruments, integrated amplifiers, digital audio and television sets. HDMI can simultaneously transmit audio and video signals, and can transmit uncompressed high-definition video and multi-channel audio data with high quality, with a maximum data transmission speed of 5Gbps.
Common HDMI interface devices are: high-definition cameras, high-definition cameras, game consoles, televisions, monitors, computer graphics cards, HDMI capture cards, set-top boxes, DVD players, and so on.

Product Features

VGA to HDMI is the HDMI signal output that converts the VGA signal and AUDIO signal of the PC into HD format. Can make the VGA output of the graphics card through this converter,The converter is converted to a full HD (1080P) large screen TV. When the converter processes the VGA signal, it does not undergo the Scaler processing. The converter only performs format conversion on the signal, and does not perform processing such as reduction and amplification of the input signal. The maximum support is 1080P or 1920X1080, and the input and output are consistent. Support all VGA standard output resolution, good compatibility, high definition and so on.

Common problem

Before powering on, you should carefully check whether the cable is normal. You must ensure that all interfaces are connected properly. Common faults are judged and handled as follows:
1: No image after connecting PC and LCD-TV, projector
First, it is determined that the wire itself is no problem, whether the source of the LCD-TV or the projector is in the HDMI state, and whether the signal output by the PC is not supported by the back-end display device (some display devices do not support the high-resolution mode of the VGA output, it is recommended that the PC The output is first set to 1024X768/60HZ). If it is a laptop, make sure the book is switched to the external display state.
2: After connecting the LCD-TV, there are black edges on the top and bottom of the screen.
Generally, the resolution of the PC output does not match the optimal display mode of the LCD-TV.
3: The refresh rate is too high, which will cause a splash screen, and the resolution must be re-adjusted.
4: Note. If the voltage is too high, it will burn out the protection circuit of the chip, causing the host to be unable to use.
5: No reason for powering up
First check that the power plug is properly plugged into the power outlet. Check if the power is on.
6: Does it appear after the TV is connected, or the screen shifts?
Because VGA manufacturers and drivers are numerous, some of the resolutions of some graphics cards are not up to standard. We recommend re-selecting other graphics resolutions based on the resolutions we have listed.
7: How to adjust the VGA output resolution?
Win7 - Right click on the desktop and select "Screen Resolution".
XP - Right click on the desktop and select "Properties" - "Settings".
8: Can't display properly after the notebook is connected?
When the notebook is turned on and the VGA output is not connected, the VGA output will be actively turned off to save power. We need to activate the VGA output. general
XP-Desktop right click -- Properties -- Settings. Select the second display and set the output.
WIN7 - Right click on the desktop, select "Screen Resolution" detection, set the output.
Notebooks generally have VGA output shortcuts (FN+F1~F12 graphic logo), such as IBM is FN+F7.

Application field
