Many Display problems can be fixed by updating the drivers. After you upgrade to Windows 10, problems can occur because your current driver may work only for the prior version of Windows. There are two ways you can update your Display drivers.

Option 1: Update drivers manually - Use DriverGuide to find the correct driver for your device and operating system. Next, download and install it by following the step by step instructions. You’ll need average to intermediate level computer skills to use this method.

If you wish to connect any device with your pc you will need to install its most needed driver first. We are sharing updated drivers link for you from its official server. Nokia n73 usb cable driver.

Option 2 (Recommended): Update drivers automatically - Even computer newbies can update drivers with just a few clicks of a mouse. Use trusted software to identify, download and install the newest driver updates for your PC in one step. Your old drivers can be backed up and restored if you encounter any problems. You’ll need novice to beginner level computer skills to use this method.

Option 1: Update drivers manually

To get the latest driver, including Windows 10 drivers, you can choose from our list of most popular Display downloads or search our driver archive for the driver that fits your specific Display model and your PC’s operating system.

This topic lists display driver features that are new or updated for Windows 8.1. Windows 8.1 introduces version 1.3 of the Windows Display Driver Model (WDDM).

Windows Display Driver Model (WDDM)^[1] is the graphic driver architecture for video carddrivers running Microsoft Windows versions beginning with Windows Vista.^[2]

It is a replacement for the previous Windows 2000 and Windows XP display driver model XDDM/XPDM^[3] and is aimed at enabling better performance graphics and new graphics functionality and stability.^[2] Display drivers in Windows Vista and Windows 7 can choose to either adhere to WDDM or to XDDM.^[4] With the removal of XDDM from Windows 8, however, WDDM became the only option.^[5]

WDDM provides the functionality required to render the desktop and applications using Desktop Window Manager, a compositingwindow manager running on top of Direct3D. It also supports new DXGI interfaces required for basic device management and creation. The WDDM specification requires at least Direct3D 9-capable video card and the display driver must implement the device driver interfaces for the Direct3D 9Ex runtime in order to run legacy Direct3D applications; it may optionally implement runtime interfaces for Direct3D 10 and higher.

Features enabled by the WDDM[edit]

WDDM drivers enable new areas of functionality which were not uniformly provided by earlier display driver models. These include:

Virtualized video memory[edit]

In the context of graphics, virtualization means that individual processes (in user mode) cannot see the memory of adjacent processes even by means of insertion of forged commands in the command stream. WDDM drivers allow video memory to be virtualized,^[6] and video data to be paged out of video memory into system RAM. In case the video memory available turns out to be insufficient to store all the video data and textures, currently unused data is moved out to system RAM or to the disk. When the swapped out data is needed, it is fetched back. Virtualization could be supported on previous driver models (such as the XP Driver Model) to some extent, but was the responsibility of the driver, instead of being handled at the runtime level.

Scheduling[edit]

The runtime handles scheduling of concurrent graphics contexts.^[7] Each list of commands is put in a queue for execution by the GPU, and it can be preempted by the runtime if a more critical task arrives and if it has not begun execution. This differs from native threads on the CPU where one task cannot be interrupted and therefore can take longer than necessary and make the computer appear less responsive. A hybrid scheduling algorithm between native and light threads with cooperation between the threads would achieve seamless parallelism. It is important to note that scheduling is not a new concept but it was previously the responsibility of individual driver developers. WDDM attempts to unify the experience across different vendors by controlling the execution of GPU tasks.

Cross-process sharing of Direct3D surfaces[edit]

A Direct3D graphics surface is the memory area that contains information about the texturedmeshes used for rendering a 2D or 3D scene. WDDM allows Direct3D surfaces to be shared across processes.^[8] Thus, an application can incorporate a mesh created by another application into the scene it is rendering. Sharing textures between processes before WDDM was difficult, as it would have required copying the data from video memory to system memory and then back to video memory for the new device.

Enhanced fault-tolerance[edit]

Windows Vista alerting the user of a successful WDDM recovery

If a WDDM driver hangs or encounters a fault, the graphics stack will restart the driver.^[2]^[9] A graphics hardware fault will be intercepted and if necessary the driver will be reset.

Drivers under Windows XP were free to deal with hardware faults as they saw fit either by reporting it to the user or by attempting to recover silently. With a WDDM driver, all hardware faults cause the driver to be reset and the user will be notified by a popup; this unifies the behavior across vendors.

Previous drivers were fully implemented in kernel mode, whereas WDDM is implemented partly in user mode. If the user mode area fails with an unrecoverable error, it will, at the most, cause the application to quit unexpectedly instead of producing a blue screen error as it would in previous driver models.

WDDM also allows the graphics hardware to be reset and users to update drivers without requiring a reboot.^[2]

Limitations[edit]

The new driver model requires the graphics hardware to have Shader Model 2.0 support at least, since the fixed function pipeline is now translated to 2.0 shaders. However, according to Microsoft as of 2009, only about 1–2 percent of the hardware running Windows Vist
