7 8 supports dual graphics switching, while Windows XP does not support dual graphics switching.

Lenovo dual graphics card how to switch this question is not easy to answer,Because there is no notebook model without a notebook, it is not easy to solve it,For example, the graphics card switching of A card and N card is different,A few years ago, most of the notebooks used manual switches for dual graphics card switching,Mainly because the XP system commonly used at that time could not support the fast hot switching of the boot state。 Most of today's notebooks use the Windows 7 system, which can support the switching of graphics cards at the driver level, and you can switch directly in the system, however, the switching of the graphics card of A is manually selected, and the switching of the N card can realize the automatic identification process to determine whether you need to start the independent graphics card.

Switching between discrete graphics cards using N cards

It is more cumbersome with a card pair, but it can be fully intelligent when it is set, of course, it can also be set by default, and the Optimus technology developed by NVIDIA does not require the user to intervene by himself, the system will automatically judge the current task, and then select the graphics card to perform the task. Of course, if the driver cannot be correctly identified, or some programs do not need to use a discrete graphics card, but the user wants to run with a discrete graphics card, they can also manually set the program to run with a discrete graphics card, but this will increase the heat dissipation burden of the notebook for no reason, and the result of the high rotation of the cooling fan is that the speed of dust accumulation is accelerated, and the dust needs to be cleaned frequently.

Right-click on the desktop with the mouse, click on the NVIDIA control panel, there is a vertical column on the left, click Manage 3D settings, there is a preferred graphics processor in the main section, select "High Performance NVIDIA Processor" (in the global settings), click on the program settings above, and in "1Select the program you want to customize, "Select the game you want to play (if you don't have the point to add it yourself), in "2Choose your preferred graphics processor for this program: "Choose a high-performance NVIDIA processor and you're good to go!"

Properly install the driver, System W7, you can choose the power supply for energy saving and high efficiency, switching.

How do I switch between the discrete graphics card runners on a dual graphics machine? How do I switch between discrete and integrated graphics?

I also asked this question, and I heard from the people at the service station that it will switch automatically, and if you manually do it, you can dial the metal button on the left and right of the lower right foot.

Right-click and then click on Configure Interchangeable Graphics Card, and you should be able to switch. You can try.

Update the graphics driver.

The graphics card should automatically adjust the switch based on the current performance of the machine.

How do I switch discrete graphics cards for Lenovo laptops?

Flash the BIOS and set it to manually switch.

Nowadays, most computers have such a feature: CPU integrated core graphics card, plus the computer is also equipped with a discrete graphics card, such a computer has dual graphics cards, under normal circumstances, the dual graphics cards will automatically switch to intelligent operation. However, due to the limited performance of the CPU integrated graphics card, it cannot be compared with the discrete graphics card, and in addition, when running some games on dual graphics computers, the game may not be installed or crashed due to compatibility.

In this case, we usually need to switch from dual graphics cards to discrete graphics cards, that is, specifying that the computer runs programs or games on a high-performance discrete graphics card, which not only provides the best performance, but also solves some compatibility issues.

Lenovo U460's graphics card belongs to the entry-level independent display card in the N card, so the graphics card switching method of the N card is as follows:

1. In the blank space of the computer desktop, right-click the mouse and select [NVIDIA Control Panel], as shown in the figure below.

2. In the NVIDIA control panel that opens, in the 3D settings on the left, click [Manage 3D Settings], and then in the [Global Settings] on the right, change the option under the preferred graphics processor to [High-performance NVIDIA processor], and when you're done, remember to click [Save] at the bottom, as shown in the figure below.

In this way, you can switch the dual-graphics computer to run in a high-performance environment with a discrete graphics card by default.

Look at the manual, it is very clear.

Or you can touch the first icon from the left (a semicircle in a rectangular box) in the metal bar at the top right of the keyboard and the graphics card will be converted.

You can also find the green arc icon in the background program list in the taskbar, and click it to change the graphics card, single arc table display, double arc table independent display.

The dual graphics card is automatically switched between graphics cards, and when the system handles large traffic tasks, it will automatically switch to the independent graphics card; When the task volume is not large, the system automatically switches to the integrated graphics card, but you can also choose to use the discrete graphics card all the time, and the operation steps are as follows:

1. Right-click on the desktop and select NVIDIA Control Panel on the pop-up menu.

2.Then pop up the NVIDIA settings menu, select Manage 3D settings, and you will see the option to use the integrated graphics or independent graphics card globally, after selecting the discrete graphics card, the system will use the selected graphics card when performing tasks.

It just so happens that I have to use win7 for this computer

Second, install the driver.

Thirdly, right-click and you will find that there is one more Configurable Swappable Graphics Card to select the desired program as High Performance.

You'll say why I'm still stuck playing the game when I'm set up.

Some games have extensions, such as Aion, where the web page pops up first, and then the selection is entered into the game, which makes it impossible to use a discrete graphics card.

Since you can't find the game's exe at all, set the graphics card to a permanent discrete graphics card!

How do I set up a permanent discrete graphics card?

Step 1 Right-click : Show the card properties.

Step 2: Select the switchable mode in the power supply and select Manual.

Step 3: Select the switchable graphics card in the power supply Go in and choose a discrete graphics card.

There is a risk in using a discrete graphics card permanently when switching, that is, you have to back up your drivers, because there may be a blue screen during the switch, as long as the blue screen is rebooted and then install the driver, and then repeat the above steps, usually 1 time.

There are 2 switches on the right side of the machine facing you, and the rightmost one is the wireless network switch, and next to him is the switch for the switch between the independent display and the integrated display. In addition, right-click on the desktop and you will see that there is a configuration swappable graphics card option in the second row of the right-click menu, which can also be switched by clicking that. I hope that students who have already purchased this machine will read the manual first and will not waste much time.

Hope it helps you and have a great day!

There's a VGA switch under the right palm rest, next to the W L switch. If the machine you buy supports dual graphics cards, you can directly toggle the VGA to open the dual graphics card. When the switch light is on, it is the independent display state, and vice versa.

Close all the apps. If you don't turn it off, there may be an error prompt, and then break the metal key in the lower right corner.
