I renovated last year. The sofa in the living room was about 3.5 meters away from the TV wall. At first, I considered a 65-inch TV. Later, I watched a 65-inch TV at a distance of my friend’s house. . Later, I started to project into the pit, I bought Optoma hd37, and cast Xiongyun
120-inch frame soft screen, talk about the experience of use.
1. About ambient light
The hd37 has a nominal brightness of 2500 lumens. The actual use is to watch variety shows and TV series during the day without drawing the curtains. If you are watching a movie, you still have to draw the curtains for a better effect. Normally turn on the lights when watching TV at night, and turn off the lights when watching movies or playing ps4. The effect is very good.
2. About clarity
1080p and 4k, let’s say in two situations. For games, the current 4k configuration on PCs is at least i5+1070 graphics card, and there is no big gap between 4k and 1080p at a distance of 3.5 meters. In the case of ps4pro, most games are still 4k interpolation, and the improvement is relatively limited; in terms of movies, if you are downloading the party, you will find that the 4k film sources of major pt stations are really few, and most of them are low bitrates. Blu-ray genuine party currently sells not many 4k Blu-ray discs in China
3. About the light bulb
At present, it has been used for about 1,000 hours a year, and I don’t feel any problems. I won’t be able to change a light bulb for a few hundred yuan next year, so it’s just one yuan a day.
4. About the experience
A friend bought the z9d. I came to my home and compared it. Let’s put it this way. In terms of color, my 7000-price projection is not left with tens of thousands of TV seconds left, but the 120-inch is more shocking than the 75-inch. My friend has experienced it. My projector immediately bought a hw48 plus 130 electric screen, which is definitely much better than 75.
5. About wiring
At the beginning, I didn't consider the projection, so I didn't deploy hdmi, so I had to use a wire slot to walk the open line in the corner. At present, my wife and I can still accept the open line. At present, some projectors support wireless HDMI transmission, using Zinwell's solution. Please remind that if you use wireless HDMI, the receiver and transmitter should not be close to the router, unless you cannot open the 5g channel for routing.
6. About noise
There must be a fan sound, but I feel it is acceptable. I usually turn on the sound and the sound is not very loud.
These are what I think of now. I don’t regret giving up projection on TV. The 120-inch experience is really invincible.
