How to set the parameters of the LCD monitor

The average user will buy the monitor back, directly connect the monitor to the computer on the use, and did not take into account that the monitor is a function of the adjustment. In fact, with good monitor adjustment function, not only can make the monitor display image more clear, and can make people more comfortable. We all know that the current monitor is divided into CRT and LCD two kinds. Both monitors in the adjustment options are largely the same, there are brightness, contrast, image position and other parameters of the adjustment. LCD has automatic adjustment function, CRT has demagnetization function, automatic adjustment and demagnetization with the specific structure of the two monitors. Now LCD has gradually replaced the position of CRT and become the mainstream of the market. This article takes LCD as an example to introduce the specific adjustment function. Recommended Articles

Step by Step: Learn the Basic Adjustment

First of all, you should familiarize yourself with the buttons on the monitor. As shown in the figure, the LCD adjustment buttons are generally six (monitor brand model will vary), excluding the switch button, the other five buttons function as automatic adjustment, OK, increase, decrease, menu. Several of these five buttons also integrate other functions at the same time, increase and decrease buttons in the selection of sub-menus play a role in selecting sub-menus up and down the function of the sub-menu. When no menu is called up, pressing the increase button directly brings up the contrast adjustment menu, and pressing the decrease button directly brings up the brightness adjustment menu. Of course, different LCDs may have different shortcut buttons.

When we press the menu button on the monitor, the monitor's OSD menu appears. The image on the right shows the OSD menu of a Philips 17-inch LCD, and when you bring up the menu, you can see the various adjustment options for the monitor.

With the five buttons described above, we can access any of the menus to make adjustments. After entering the sub-menu we see more options, using the OK button we can enter the light blue highlighted bar selected adjustment options to adjust. When adjusting, the effect of the adjustment will be immediately reflected on the screen, so you can just adjust the monitor according to the effect of the screen and their own needs. Due to the superiority of the LCD structure, you can get a more satisfactory image quality by pressing the AUTO button.

The lazy man's way: Auto Adjustment and Scene Mode

Because of the superiority of the LCD technology structure, so the LCD fundamentally avoids the geometric distortion of the picture reproduction, non-linear distortion. As long as you press the auto adjust button, the monitor will be adjusted to the best working condition, so that everyone only needs to adjust the brightness and contrast of the screen. Everyone's eyesight is different, it is recommended that the brightness and contrast are adjusted to their own values, these two values should not be adjusted too high, otherwise it will have an impact on the eyesight.

Many monitors provide some features called scene modes, where you can select different scene modes to suit different environments by simply pressing a button. In reality, scene modes are just some combinations of brightness, contrast, color temperature, and other parameters preset by the manufacturer. Although not very technical, this is really convenient for users, and whether or not it supports convenient scene modes has been known to be one of the factors that many consumers consider when thinking about purchasing a monitor.

Color temperature adjustment can't be ignored

General LCDs offer color temperature adjustment, and users can generally choose one of three color temperature options - 6500K, 9300K, and user-defined - as well as simulate different color temperatures through the adjustment of the three primary colors. The color temperature of the light emitted by the general bulb is 2800 K, while daylight is 5300 K. Due to the different principles, LCD and CRT in the same color temperature under the performance of the color is different. For most people in the East, the CRT is set to 9300K is more comfortable, while the LCD is set to 6500K is more comfortable. Of course it varies from person to person, and is best customized by the user to look comfortable anyway.

Trivia: Color temperature is a physical quantity used to define the color of a light source in lighting optics, which is defined as: heating a black body to a certain temperature, the color of the light emitted by its color and the color of the light emitted by a certain light source, the temperature at which the black body is heated is called the color temperature of the light source, referred to as color temperature.

How to modify the 3389 port number

1, change the port: simple steps: open the "Start ?ú Run", type "regedit", open the registry, enter the following path: [HKEY_LOCAL_MACHINESYSTEM CurrentControlSetControlTerminal Server Wds dpwdTds cp], see the PortNamber value? Its default value is 3389 (changed to decimal display), change to the desired port, example 6689.

2, and then open the [HKEY_LOCAL_MACHINESYSTEMCurrentContro1SetControlTenninal ServerWinStationsRDP-Tcp]. Change the value of PortNumber (default is 3389) to port 6689 Close the registry editor and restart the computer to take effect.

Note: A reboot is required for the settings to take effect. The ports for both items should be the same

The connection may not be enabled or the computer may be too busy (to solve the problem of not being able to connect to Remote Desktop)

The problem is as follows:

The client is unable to establish a connection to the remote computer.

Possible reasons for this error are:

1) The remote connection on the remote computer may not be enabled.

2) The maximum number of connections on the remote computer has been exceeded.

3) A network error occurred while establishing the connection.

Remote Connections shows that the connection may not be enabled, or the computer is too busy to accept a new connection How do I fix it?

The client cannot connect to the remote computer. The remote connection may not be enabled

Problem solved: The client cannot connect to the remote computer. A remote connection may not be enabled or the computer may be too busy to accept new connections. There may also be a network problem preventing the connection. Please try the connection again later. If the problem persists, please contact your administrator.

When faced with a problem similar to the following when connecting to another computer using a remote terminal:

The client cannot connect to the remote computer. The remote connection may not be enabled or the computer may be too busy to accept new connections. There may also be a network problem preventing the connection. Please try connecting again later. If the problem persists, please contact your administrator.

The solution is as follows

Remote Desktop, in fact, is very simple. The server side is a two-step process. -Ensure that the "Terminal Services" service is in the "Started" state. Figure 1:

If it's not "Started", double-click the service and select "Start".

Next, take a look at the second step:

In My Computer - right-click - Properties - Remote - Remote Desktop - hook "Allow remote users to connect to this The first step in the process is to make sure that you are able to connect to the computer from a remote location, and that you are able to connect to the computer from your computer from a remote location. Therefore, in this season, all computer users need to pay special attention to the following aspects, in order to do the corresponding preventive work. Excessive humidity can cause the exposed metal parts of the circuit boards inside the computer or inside the monitor to rust (resulting in poor contact), or even short-circuit between the pins, or worse, cause the power supply to short-circuit internally and burn out.

Therefore, if you live in a relatively humid room (e.g. a bungalow), it is recommended that you place the case on a desktop rather than on the floor, and that you collect a few packets of desiccant (a small packet of granular material) in a food bag and place it in the empty space underneath the case to absorb the moisture.

Higher operating temperatures can lead to crashes and other malfunctions, and it is recommended that you do not use your computer at ambient temperatures higher than 30 degrees Celsius, as the ambient temperature rises by 1 degree Celsius, and the computer's operating temperature is likely to rise by several degrees Celsius or even a dozen degrees Celsius.

In addition, good heat dissipation is also necessary, in addition to choosing a good cooler (refer to the CPU cooler cross-testing feature in this issue of D4), it is also necessary to do a clean sweep of the environment in the chassis (refer to the article "Summer Computer Dust Removal in the 25th Edition of D7"). We recommend using temperature monitoring software such as Core Temp to keep an eye on your CPU's operating temperature. If you find that the temperature is too high for a long period of time (over 60°C), you should pay attention to improving heat dissipation.

This is a topic that has been talked about many times, and to summarize, in the case of a well grounded and reliable overcurrent protection (e.g., an air switch) in the home circuit, the first line of defense is the lightning outlet, the second line of defense is the computer's power supply, and if these two are not prevented, the likelihood of damage to the hardware is very high.

Of course, the easiest way is to develop good habits, don't use the computer when thunder, unplug the socket and the network cable, which is more insurance than any insurance device.

Summer computer dust to pay attention to

For most ordinary users, the chassis that is a long time will not be opened once, not to mention the computer to do a clean, now the weather is hot, many users began to find their computers frequently crash, reboot of the 'problem' - the accumulation of dust has been a long time finally! began to play the role of "insulation", the computer does not die strange. So let's grab a brush and a leather tiger, and let's give your computer a clean bill of health.

The coolers on the CPU and graphics card are simply dust absorbers, and we need to clean them first.

Remove the CPU cooler (see the D16 Beginner's Academy article in this issue for instructions on how to install and remove various types of coolers), then remove the cooler fan (which is usually held in place by plastic grommets or screws), and use a brush to clean the blades of the fan, both front and back. The next step is the heatsink, if the dust has built up into a mass, it is recommended to reverse the heatsink to snap it to the ground first, shake off the large mass of dust, and then use a brush to clear the rest of the way, if some of the dust in the crevices can't be brushed off, you can consider using water to flush it out, as long as it is flushed clean and then leave it to dry completely.

The graphics card cooler can also be used in the same way, but the graphics card cooler is more difficult to dismantle, requiring some hands-on ability, the average gamer, really can't take it down, just use a brush to clean the fan and a large mass of dust.

Note: The heatsink can be washed, but the fan should not be washed - it's not easy to dry it out because of the water that gets into the motor. Also, be sure to make up some silicone grease on the bottom of the heatsink before putting it back together to ensure good contact.

In addition to the radiator, which has gaps everywhere, the board, which is full of components, is also a big dust eater. As you can see, the CPU power supply circuitry on the motherboard, and the part of the graphics card where the radiator airflow passes through, are full of dust. It is recommended to remove the entire motherboard from the chassis before cleaning it. In addition, the memory and PCI-E slots, SATA ports should also be cleaned, it is easy to accumulate dust inside, which can lead to poor contact with the graphics card or memory, SATA cable re-insertion.

Key note: Don't wash with water! The heatsink can be washed, the board should not be washed. Although theoretically it can be washed, the difficulty lies in how the average user can get it dry ...... The water beads in the crevices of those components and soldering pins are very hard to take care of, and can lead to rusting of some metal contacts. So it's safer to use a brush and a leather tiger to deal with the dust on those components. Chassis section

It's a good idea to take all the accessories out of the chassis and do a thorough cleaning. The bottom of the case, the front air intake, and the rear air vents are where the dust accumulates and need to be cleaned in a focused way. A brush and a leather tiger are good here, and if parts of the case are really dirty, you can clean them with a semi-wet rag with a cleaner.

Key note: Be careful of scratching your hands on the inside edges of the chassis, especially on some low-grade chassis, where the edges are very sharp, so be careful when you use a rag.

Other parts

Such as hard drives, optical drives, these devices on the shell of the accumulation of dust, with a slightly wet rag to wipe off, and then wipe with a dry rag can be, can not use a wet rag to wipe the exposed circuit board part.

In addition to these precautions, in addition to the computer to do cleaning, but also a little more detailed, mounting and dismounting parts of the location and order to remember, screws, fixed fasteners do not lose - of course, there is also a point is to do the cleaning, please put on a mask, that fly around the dust is not covered!

Once you've finished cleaning your PC, you'll notice that your PC's operating temperature has dropped considerably, and the fan noise has decreased a lot.

How to modify the MAC address of your network card

Sometimes, for certain applications, you need to modify the physical address of your network card's MAC address, although it can be achieved by modifying the system's registry, but the operation of the registry is more complex, and it is difficult to achieve the general computer enthusiasts, a software called SMAC can help you solve this problem completely. This is the first time I've ever seen a program like SMAC.

SMAC allows users to convert MAC addresses on almost any NIC (Network Interface Card, or NIC) on Windows 2000, XP, 2003 Server, and Vista, regardless of whether or not these NIC products allow modifications. The author briefly describes how to use the software for your reference.

After downloading and installing the software, the corresponding icon will be generated on the desktop, double-click to run (if you can't run it, please copy the cracking patch to SMAC's installation directory and run it on the line), the main interface, as shown in the figure, will be modified to fill in the MAC address in the "New Spoofed MAC Address", click on the right side of the "MAC Address", and then click on the "MAC Address" button. ", click on the right side of the "Updata MAC" button, wait a moment, the software will be prompted to restart the computer, at this time, An request to restart the computer to complete the modification of the MAC address, in addition to the software interface can be seen in the software can also randomly generate the MAC address, while also showing the product information of the network card. The first step in the process is to create a new MAC address, which will be used as a reference point for the MAC address of your computer.
