Matching the components of the Choosing and Troubleshooting Display Systems to the needs of the computer owner when updating or purchasing a system is critical to user satisfaction. Knowledge of the basic steps in troubleshooting a performance is the key to a quick repair when a component fails to operate properly. In this lesson, we set out the basic steps to follow in selecting the right class of performance hardware for a customer, proper care, and troubleshooting common problems.

Choosing a Display System

Help monitors a user choose the right display and is relatively simple, despite the variety of adapters on the market. Performance is the part of the system that interacts with the user and “sees” the most, and this is a major factor in overall performance. Within the boundaries, the buyer needs to get the best performance possible.

A major consideration is the maximum viewable area. For users who do not need only one program at a time, or who need high resolution, a basic monitor should suffice. Graphics intensive applications and monitors with large fast refresh rates, and multitasking calls for display cards to match.

Applications and games designed for graphics intensive drawing and painting or for CAD (computer aided design) will be used which users usually prefer a fast graphics optimizer, with VRAM or WRAM and higher resolutions and those refreshing Will be

Multi-media systems, TV tuners, and hardware DVD acceleration (the signal is displayed on a regular TV set using the NTSC format, usually in the form of an RCA jack with the help of) offer the TV out that the card can benefit from is .

Common trade offs between cost and performance apply, but less so now compared to the days of the $ 3000 high end card. Today, a user can buy a fast, high-quality adapter for $ 250 to $ 300, and an adapter of acceptable speed with true color performance for $ 150 without extras and expensive memory types.

Consider an FPD offer, especially if customer desktop space is limited. Remember that FPD may require the purchase of a special display adapter.

In recommending a display system, start with the needs of your customers, followed by their priorities, and match the available budget as much as possible. Keep in mind that the performance optimizer is only part of the equation. The cost can be contained by accepting a smaller monitor or a slower refresh rate. Excessive cost reductions may leave customers with a display that does not support the performance or tasks that can cause the user eye strain from the flicker that occurs at slower than acceptable refresh rates for the selected resolution.

Troubleshooting Display Systems

MDA cards were standard, technicians had some problems with the display system. If the cable was connected properly and the monitor was working, then the user is a snap. Today, the wider range of card options and the mix of resolution, refresh rate, and operating system means users need help with displays more often.

Despite the increasing complexity of the display system, some of the most common sources of problems are detected: the cable is improperly connected or damaged, lack of power, improper monitoring adjustments, corrupted or incorrect drivers, and memory conflicts with other components can go. The following checklist can help you troubleshoot common performance issues you are likely to encounter:

1. Verify both power and monitor display adapter cables are properly attached. Failure to attach them properly can lead to no picture at all or an erratic image with the wrong color. Monitor cable has been removed and reseated, bent pin problem may occur. Make sure that the power and PC monitor is reaching and that they are both turned on.

2. Make sure that the adapter is properly seated in the expansion slot.

3. System boot. You get an image during self-test (post) on power, but the computer does not load the operating system, suspected memory or driver problems. If the system repeatedly hangs during Windows operation, the same is true. Try to work in safe mode. If that is successful, use Device Manager in the Control Panel System Utility to reinstall the drivers and resolve any hardware or memory conflicts. (From the beginning, select Settings, Control Panel, double click the system, and then select the Device Manager tab.)

4. Reset 640 × 480 resolution card in 16 color VGA mode at fresh rate 60 Hz. The card works in these settings, in Windows, in normal mode, but fails at high resolutions, color depths, or refresh rates, to check the capabilities of the drivers and display components.

The adapter can produce a high scan of the screen, even if the monitor does not exceed the approved refresh rate. The result will be an unstable or unclear image, which can damage a monitor very quickly.

All these enumerated attempts fail, try a different performance adapter or test the hardware set on a different PC to see if one of the monitoring or components has failed and requires repair or replacement. In most cases, an out-of-warranty card is not worth repairing; an expert has failed to perform a monitoring check.

Summarize the main elements of this lesson on the following points:

Choosing a new display system or upgrading components is a matter of matching user needs to hardware available within the allowed budget.

Price is not the only issue when buying a display system. The quality of a display is a major factor in computer performance and usability.

PC performance problems can cause a variety of symptoms on a system, from screen distortion to machine failure to boot.

Using a step-by-step approach and walking through possible problem solving combinations provides a quick way to solve many performance-related difficulties.
