Why can t I install the graphics card driver in full screen There is an extra black circle on the ou

In the graphics card control panel settings, there is an option to adjust the size and position of the desktop (it may not be called this), and there is a graphics card zoom function to use. If you can't click on it, then change the version of the driver. Generally, the officially released drivers can be used.

Click again on the desktop, there should be an ATI control panel option, or enter the ATI control panel from the win7 control panel. Then just look for it in the control panel.

Run the registry command regedit

Find it in order: hkey local machine---system---controlset001---control---graphicsdrivers---configuration Right-click configuration, select Search, enter scaling, find scaling in the right box, right-click scaling to modify Change the value to 3, the original value is generally 4

99% good, try it

If it's a notebook, you try to reinstall the driver, pay attention, you have to find the right version, if people don't explicitly say that they support your graphics card, then it's likely to be a problem, even if your graphics card is of that series.

If it's a desktop, in addition to the above questions, you can try adjusting the display settings of your monitor.

If you are a laptop, you can reinstall the graphics card driver to solve the problem.

For desktops, press Auto (Auto Adjust) or Widescreen on the monitor panel to switch between (some monitors have this button).

Display viewing angle:

The viewing angle of an LCD monitor is symmetrical from side to side, while up and down are not necessarily symmetrical. When the incident light from the backlight passes through the polarizer, liquid crystal, and orientation film, the output light has a specific directional characteristic, that is, most of the light emitted from the screen has a vertical direction. If you look at a completely white picture from a very oblique angle, you may see blacks or distorted colors.

In general, the up-and-down angle should be less than or equal to the left-right angle. If the viewing angle is 80 degrees to the left and right, it means that the screen image can be clearly seen from the position where the screen normal is 80 degrees. However, due to the different range of human vision, if you do not stand in the best viewing angle, the color and brightness you see will be incorrect.

On the market, most LCD monitors have a viewing angle of about 160 degrees. With the development of technology, some manufacturers have developed various wide-viewing angle technologies in an attempt to improve the viewing angle characteristics of liquid crystal displays.
