[TV installation]How much is the LCD TV installation height? Wall-mounted TV installation considerations
How to choose the size of LCD TV
In order to more scientifically determine the height of the LCD TV, it is necessary to select the appropriate room size and viewing distance to choose the LCD TV. Reasons:
1. Choosing the size of the LCD TV according to the size of the room can make the overall arrangement look coordinated.
2. Choose according to the viewing distance, it will be more comfortable to watch TV. Here, the room size is used as a reference to determine the size of the TV to buy.
I suggest:
The straight-line distance within 3 meters, the size of the room within 20 square meters, choose 29-34 inches.
The room size is between 30-40 square meters, choose 35-43 inches.
The straight-line distance of more than 4 meters, the room area is more than 50 square meters, choose a 43-inch LCD TV.
What is the general installation height of the LCD TV wall?
After determining the size of the LCD TV, determining the installation height of the TV is actually to determine the installation height of the TV wall (there are the relevant reference manual). In simple terms, the center line of the LCD screen of the TV is flush with the human eye after the person is seated, and is slightly higher than 10-20cm. It also depends on the height of your sofa. It is best to sit the TV so that your line of sight is slightly lower by 5-10 cm. This is an ideal height, and more importantly, it keeps the eyes from getting tired when watching for a long time. The detailed height of LCD TV installation can refer to the following data. Note: The height range of TV installation is 1/3-2/5 of the total height of the TV wall. The width of the TV is generally about 1/4 of the TV wall.
1. The home wall hanging can be kept at 0.9-1.1 meters.
2. The shopping mall should be suspended at about 1.6 meters, and the wall-mounted should be about 1.3 meters.
3. The hospital hall should be suspended at about 1.6 meters.
4. The ward wall should be hung at about 1 meter, which is an ideal height.
LCD TV wall-mounted installation method
At present, many LCD TVs are often sold as bare metal when they are sold, and the merchants are not responsible for installation. In order to reduce the price of the whole machine , Some businesses do not provide wall mounts, users need to ask professionals to install the LCD TV to complete the “wall mounting”, but this must pay a lot of installation costs, so many users choose to install it by themselves. Now I use the LCD TV bracket to describe the installation environment, installation location, bracket load-bearing, load-bearing wall conditions, bracket purchase and installation skills, etc. to describe some professional factors that consumers need to consider when installing themselves and master installation skills to ensure that The LCD TV works normally.
1. Load-bearing walls
This is the first problem to be considered before installation. In rural or old-fashioned communities, the outer walls of some houses are solid In addition, the inner walls of the other compartments are all hollow, and the wall-mounted TV cannot be installed at all, and can only be viewed on the cabinet, or the TV will fall off the wall and break due to forced installation. In fact, the installation of a wall-mounted TV has stricter requirements on the firmness of the wall, and the wall in the home is not suitable for installing a wall-mounted TV. Therefore, consumers should examine the cement structure of their houses before purchasing “wall-mounted” LCD TVs. The LCD TV needs to be wall-mounted, and the wall must be solid brick, concrete, or a mounting surface of equivalent strength. According to the national “LCD TV Installation Service Standard”, the installation points: the bearing capacity of the installation surface should be guaranteed not to be less than 4 times the actual load capacity of the TV, and the TV should not fall over when it is tilted forward and backward 10 degrees after installation.
2. Installation skills of different types of walls
The types of walls are mainly divided into brick walls, wooden walls, decorative walls, glass walls, and marble walls. These walls have strict requirements on the size and spacing of screw holes. When installing a wall-mounted LCD TV, users should pay attention to different installation techniques according to different types of walls:
1) ordinary brick wall
No special tools and techniques are required for installation, just punch holes in the wall with an impact drill (pay attention to the diameter of the drill bit), then insert a plastic expansion tube, fix the product with screws, and hang it on the TV.
2)Board walls
Board walls are divided into solid wood planks and gypsum board walls. As long as the solid wood board has a thickness of 2cm, use the self-tapping screw to directly fill the ring. If it is a gypsum board wall, after selecting the positioning point, first use a utility knife to drill a hole in the center of the hanging point (with the size that your fingers can enter), and then put a 2cm thick piece of Long wooden slats make the self-tapping screws pass through the gypsum board and enter the wooden slats during self-tapping, so that the force-bearing area is increased.
3) Marble walls
Marble walls are divided into solid marble and patterned marble. For the overall marble slab, glass drills should be used. When using a glass drill, it is necessary to water the glass drill bit while drilling, so as not to burn the glass drill bit. If the glass drill is really difficult to drill through the wall, an impact drill can be used when the drill is halfway through, but the impact drill must be placed on the electric drill gear, otherwise the marble will be cracked. After the holes are made, the expansion screws can be installed until they are tightened. For marble with patterns, be extra careful when drilling, because marble with patterns has lines on it, and a slightly larger vibration force will cause cracks to expand.
4) Glass Wall
The glass wall is followed by a brick wall and a board wall. If there is a brick wall behind the glass wall, after selecting the position, first use the glass drill to drill, and also need to pour water to the glass drill while drilling. The selected glass drill bit must be larger than the impact drill bit for the brick wall, and the glass hole must be drilled well. After that, drill the inside brick wall with a hammer drill. In order to prevent the glass from being crushed when screwing on, it is best to use a screw with a large expansion tube as a filler ring. The thickness of the filling ring can be selected to be slightly thicker than the glass, and then tighten the screws. If there is a wall behind the glass plate, you only need to drill the glass hole with a glass drill. The glass hole should be slightly larger. After drilling the hole, you can put the filling ring, and then self-tapping with self-tapping screws. The self-tapping screws used must be A little longer than the thickness of the glass + the thickness of the wood.
Precautions for wall-mounted LCD TVs
1. To accurately locate the installation position of the LCD TV on the installation surface, the positioning accuracy must be ensured and fixed well Mounting surface hanger section.
2. In general LCD TVs, the heat dissipation grid is usually designed on the back or the side and back, so the back of the TV and the upper, lower, left, and right sides of the TV need a space for ventilation and heat dissipation. A distance of about 15 cm.
3. Since the various interfaces of the TV are basically arranged on the back, the various data cables cannot be bent over 5 minutes against the wall, otherwise it will be easily damaged.
4. Be careful during the installation process. When moving the whole machine, it should be handled with care, and bedding should be prepared to prevent scratching the display screen.
5. Follow the requirements of the hanger installation manual and follow the steps to install it.
6. If the display screen has connecting parts with speakers and mounting brackets, pay attention to distinguish the left and right and the front and back.
7. If you need to connect the speaker cable, you should pay attention to the positive and negative polarity of the speaker cable to prevent the sound of the left and right channels from being reversed.
8. After the display screen is hung up, it is necessary to measure with a level ruler, adjust the screws of the hanger so that the display screen is completely in a horizontal position, the positional translation error of the LCD TV installation should be less than 1cm, and the left and right inclination should be less than 1cm. The error is less than 1 degree.
9. Protective devices such as air switches should be installed on the power line, and the wiring length of the power line and signal line should not be changed at will. It must be lengthened or changed, and cables that meet the requirements should be used.
