The problem of connecting the laptop and LCD TV via VGA cable

Haha,Mine is also 42 inches.,Skyworth's,I just connected it with VGA last night.,Watched a movie.,And hit CS.,One word,Cool.。

The operation is: connect the VGA cable, turn on the computer, right-click on the desktop properties, enter the settings, select another one in the display (there are two), and then select the box below. At this time, you can adjust the resolution and restart.

If it hasn't come out yet,Right click on the desktop,Graphic output selects TV on it。 At this time, you can also choose the resolution, and you can also adjust it on the TV. OK!

Don't be so complicated, just use the function keys of the notebook and the switch key of the notebook (f is unknown, different computers are different) until there is an image.

It depends on what TV you are. Generally, the refresh rate is adjusted to 60HzThe resolution is adjusted to 1020*768

The TV itself automatically adjusts the proportions of the picture. Hehe. If the TV supports a wide format, you can also put the resolution to 1440*900...

You don't have to worry about anything else. Most of them are automatically adjusted. Once you've set it up, refresh it.

If you can't start back, it's OK.

Select "Copy" in the multi-screen mode of the graphics card's settings menu.

You can adjust the display properties of the notebook in the control panel to control the size.

You can install a splitter so that both the TV and the computer can be displayed.

Newer TVs and monitors now have an HDMI port to connect in addition to the VGA port, so you can check to see if you have an HDMI port on your (discrete) graphics card.

If your computer only has one VGA port, and you can't connect multiple monitors with your existing equipment, you need to buy 2 more VGA cables, and then buy a VGA crossover (common models: 2 in, 4 in, 8 in, 250MHz VGA divider). The computer is connected to the VGA crossover, and then 2 wires come out to connect to the monitor and TV.

For example, it's like a water pipe divided into 2 parts.

Once this is done, the content of the two monitors will be exactly the same as if you were using a normal computer.

The computer is connected to the LCD TV, and it is generally necessary to purchase a VGA cable, and the connection method is as follows:

1. First of all, prepare a VGA cable, which can be used to synchronize the screen display on the computer to the TV.

2. Find the VGA socket on the computer and connect one end of the VGA cable to the VGA socket on the computer.

3. Find the VGA socket on the TV and connect the other end of the VGA cable to the TV.

4. Turn on the TV and press the "Source" button on the TV remote control.

6、After the TV is switched to VGA mode, it can be connected to the computer,Display the picture of the computer。

In order to get a better display effect, it is recommended to adjust the resolution of the computer according to the size of the TV, generally 32-inch TV can adjust the computer resolution to 1280*720 pixels.

Haha,That's the resolution of your TV is too high.,I can't stand it.。 Generally, the old TV can't use the resolution of the computer's display at all,If it's the night crystal you buy now,Try it800x600Resolution,If you can do it, try it again1024x768,I think about the general TV is just these two common resolutions,The big TV must not stand it。

When the VGA cable is connected, how to set the LCD TV as a monitor, and how to turn off the laptop monitor is as follows:

First of all, use a data cable or a VGA video cable, that is: the data cable connected to the desktop computer host and the monitor, serial port type, connect the laptop computer to the TV, one end to the portable VGA port, and the other end to the TV PC input port as shown in the figure.

Turn on the TV, and then switch the signal input to PC mode (i.e., computer input), the switching steps are as follows: manually touch the "Program Source" button in the lower right corner of the TV or directly press the "Program Source" button in the upper right corner of the TV remote control until the "PC" letter appears on the TV.

Turn on the power of the laptop, under normal circumstances, the content of the laptop display will be directly transferred to the TV display, if it is not displayed, then: press the fn key (the lower left corner of the keyboard) and then press the f3 key at the same time (as shown in the figure), (depending on the computer, it may be other keys in the F1-F12, but the keys are marked with the computer and TV logo and there is a vertical separation in the middle) to switch.

If the conversion is still not successful after completing 1-3, check as follows: Click on the laptop desktop or "Network" (Online Neighbors) and "Right Mouse Button" > Properties >> set it in the "Display Device" column to select the second display device (i.e., the external TV), check "Expand the desktop to this monitor", and click "OK" to complete.

If nothing is displayed in step "4", it means that the laptop graphics card version is low and you need to install a higher version of the graphics card driver. The installation steps are as follows: My Computer > Right Mouse Button > Device Manager > Display Adapter > After popping up the device adapter model, "double-click" >Driver" >> Update the driver (at this time, the computer needs to be connected to the Internet to automatically search for the appropriate graphics card driver) >OK" and restart the computer after completion.

Perform steps 4-5 and you're done.

To display content on both a laptop and a TV at the same time, do the following: Laptop desktop "Network" (Internet Neighbors) >Right click" > Properties > Control Panel > Hardware & Sound > Display > Connect to External Displays > Select "Copy these displays" > in the multi-monitor box.

o(o,The driver has not developed to that extent,The desktop expansion of the graphics card,It is necessary to have a version,A native,The display screen is in a display state,You can carry out desktop expansion Di!

My notebook also has to be kept bright before I can expand my desktop.

Got it, do you want to keep the display of your laptop turned off while the TV is showing to save power?

The biggest feature of the notebook is: close the lid that is, (enter) sleep, state, you might as well try it, ok?

The FN+ display toggle symbol, generally in F1-F12 where one of the keys has two screen-like logos, separated by a slash.

To use the monitor and extend the desktop, you want to duplicate the desktop use, and then, close the lid and you're good to go.
