First dive out of the diving chart of the Optoma GT750E projector:
Before this, although the water was over the projector, I never thought I would buy one, but I believe that most of the friends who are valued are the same as the owner, and the so-called bargain goods are impulsive. If there is any historical low price, God's price, but I could not help but want to chop the hand (see what to see, say How about you ), but the projector is large, after all, it was first seen in January when it saw the 639 knife. In the post, "GT750E is a popular model discussed by the forum users, known as the king of the 3D short focal 720P projector. It is very suitable for use in small living rooms and bedrooms. It comes with a Traditional/Simplified Chinese menu, and its short focal point is very powerful. It has a 90-inch screen at 1.45 meters and a 120-inch screen at 2 meters. The 3D solution is cheap and it costs 100 yuan. The introduction of Skyworth's infrared open-door glasses could have impressed me deeply, but at that time I still held back. By April, when the price was refreshed to 589, the lord couldn't sit still and started to try, so he studied it. Offers information mentioned in the AV199 forum posts, posts "ultra-short throw distance, about 1 meter point I almost can fill a 120-inch 4: 3 large screen, quite a force, quite shocking." because the main line and Buying a second-hand house 10 years ago, when the room decoration did not consider wiring and projection placement issues, if the projection of the conventional focal length is more difficult, ceiling must be very troublesome, but this ultra-short focus projection is just right, and 639 The knives are all historically low prices, and now they are down by 60 knives. The price should not drop any further. So after persuading the Queen, they place orders on April 4.
Unexpectedly, after 3 days, April 7th, the price of the machine dropped by 10 to 579. In the next 3 days, on April 10th, the machine dropped 10 to 569. Finally, after 8 days, Zhang Aunt refreshed. The news that the machine fell 529 was very shocking, rubbing, and dropped 40. This TM is a diving king. A look at Meiya, but not to show the price, the following explanation is due to manufacturers policy reasons, do not show prices, to See prices first and add shopping cart. Add a shopping cart to see, sure enough 529, suddenly feel bad up, when the projection has been to the transfer company for 8 days, had already given up, but still try to take a look at the attitude of the United States and Asia customer service chat, Meia customer service life and death I did not give a price guarantee. I already gave up quickly. I did not know that the other party suddenly asked for senior customer service. After reading my transaction records, I said that I was a loyal customer of Meiya. This time I was compensated as an exception to the violation of the price protection clause of Meiya. , and to me to reiterate the price protection clause in the United States and Asia: can only be used once, and within 7 days after receipt. Can you imagine the feelings of the Lord at that time and think of me as a small P-people who lived in the heavens for so many years and when there was such a feeling of “God� What price protection is necessary? It is impossible. Occasionally encountered a bug, domestic electricity The dealer said that you cut it and you cut it. You told him that the order has been established and payment has been made. He directly follows the policy that delivery is considered to be the establishment of the sales contract, and the customer service does not speak it. The reply given to you is always their user manual. Those words (a certain country in Asia, saying that you are, Asia, how do you feel so poor quality ...), originally not much money, but made a very bad mood. The Lord immediately gratefully acknowledged the fact that he had spoken N times to the customer service, Thank you, and praised Meia's noble sentiments and broad minds. . Here we must particularly explain that some of the recent domestic electricity providers seem to have conscience, and bugs generally recognize it, such as a certain east of a certain point of 125-100, a letter of 99+149 , an East encounter commodity issued coupons in disguise Even if you do not meet the terms, as long as you say it makes sense they will still give some compensation based on the user level, the owner of his goodwill is also greatly improved.

It is now the S4 Finals, which is connected to the projection game, haha, La La Demacia... (The picture is the previous figure):

After seeing what ceilings, curtains, and room layouts of the local tyrants in the solar projection project, everyone came to look at the system solutions of the lords:
PCX1, 10 meters long HDMI cable X1, 10 meters long USB cable X2, wireless mouse X1, wireless keyboard X1. Finished.
1.PC usually put the bedroom, projection is sometimes seen in the bedroom, and sometimes received a living room.
2. Route. Of course, it is a straight line. Two USB extension cables are used to connect the wireless mouse and wireless keyboard transmitters.
3. Logitech K400+G700, wireless operation weapon.
4. Place the projector. A plastic bench + a plastic tray, get it. If it is in the bedroom, the bench will be saved and the direct meal tray will be on the bed.
4. The curtain. What about a clean wall with curtains?
5. Many people look directly to the speaker, send:
Remembering stickers: 1685 HiVi hivi M200MKIII2.0 speaker
A person looks directly at my wireless headset and sends:
Turtle Beach Turtle Beach X-Ray Wireless Gaming Headset Call of Duty Limited Edition
This is over, local tyrants, spray me...
"""""""""""""in conclusion"""""""""""""
Talk about the advantages and disadvantages of the machine:
advantage:
1. Short-focusing machine is very suitable for those who want to decorate the house in front of the house without wiring, without ceilings, where you want to put, and it is more convenient to use.
2. Rich interface: With two 1.4 hdmi interfaces and one infrared interface, the cost of the 3D solution is low: Buy inexpensive infrared open-door glasses and infrared transmitters. One main transmitter, 88 yuan, 45 glasses, bought 2 90 yuan, plus 10 yuan postage, spent a total of 188, there should be no cheaper than this "active" 3D solution.
  3. The price is cheaper. Well, this is the biggest advantage.
Disadvantages:
1. WXGA (1280 × 800) resolution, only 720P, not to 1080P, unfortunately.
2. Everyone should know when the company uses the projector, the projector in addition to a focus ring should also have a zoom ring, this projector can only focus ring without a zoom ring, to adjust the image size only by moving the projector itself,
Popular science:
The zoom ring (closer to the body is the zoom ring) moves the lens to enlarge and reduce the image.
Focusing ring (smaller in front of the lens is the focus ring) Adjust the focus ring to ensure the image is clear.
