LZ ~ first of all, the current domestic online cinema can not provide real high-definition pictures. The standard of high-definition is 1080p, and the resolution is 1920 * 1080, which can not meet the requirements of transmission bandwidth through the Internet.
LZ ~ first of all, at present, the domestic online cinema can not provide real high-definition pictures. The standard of high-definition is 1080p, and the resolution is 1920 * 1080, which can not meet the requirements of transmission bandwidth through the Internet.
.
about the type of TV you said.

TV type: LCD, plasma, led, LCD, etc

I will classify you, It is mainly divided into LCD screen and plasma screen.
.
among them, LCD screen (CRT) can be divided into LED (light emitting diode) backlight module and CCFL (cold cathode fluorescent lamp) backlight module according to the backlight.
there is no classification of plasma at present.
.
ordinary users can not feel the difference between the two types when they are applied But in terms of color, LCD is recommended.
.
.
and then "full HD"
means that the screen resolution of TV can reach 1920 * 1080 (or higher), Now, almost all TVs above 40 inches can meet this standard.
.
about the size: the owner should consider comprehensively according to his own economic ability and the location of the TV.
generally, the best viewing distance of 40 inches is about 3 meters to 60 inches, which I have not calculated.
it is estimated that it will be more than 5 meters away.
now there are few home TVs of 60 or even 70 inches.
I have not paid much attention to such a large size

.
Third, the establishment of home theater: apart from TV, power amplifier, audio and output source (player or HTPC or PMP) should also be considered.
in addition to TV, the construction of home theater should be carried outIf you have something you don't understand, you can cut me short.
I use my laptop and PMP's HDMI for video output.
I use SPDIF to convert optical fiber for audio output. The video uses a 42 inch TV, audio power amplifier, 5.1 physical channel soft simulation, and 7.1 channel output. The effect is just getting started, because the equipment is not very good. It's all household grade, and the whole set costs 6000 (notebook) + 4000 (power amplifier In the end,
if the building owner has requirements for display size and is able to put in 60 or even 70 inch TV, it is better to consider that HD projector is much cheaper than 60 or 70 inch TV, and the projection size can reach 100 inch + ~ of course, there are also requirements for placement, The projection distance and screen size should be satisfied.
.
I am planning to purchase this set of projector + projection screen now.
it's just that the projection distance in the living room of my family is a little small, and it can't reach the ideal projection size.
~.
.
my personal experience is pure hand-made.
I hope it can help LZ. I am a prospective fan of home cinema, The TV signal is a unified national standard.
so the performance index of TV is the same. Led and LCD are all LCD screen TVs. Led uses LED as the backlight of LCD screen, and LCD uses fluorescent tube as the backlight of LCD screen, because led and lcd use LCD screen to display images, Therefore, the image quality of the two is the same. Plasma TV displays images based on the principle of gas discharge, and there is no viewing angle or tailing. LCD TV and plasma TV can be distinguished by viewing angle.
