The second opening: (American Shopping Thoughts)
I bought these electronic products in the United States mainly through online shopping. One is that some products you didn't need, but businesses can occasionally give you a discount that doesn't feel sorry for yourself. Something below $200 can sometimes be half price (not the kind that is marked highly and then discounted in China). The more expensive items such as mobile phones and computers can be reduced by US$100 or US$200. The high-end products can also drop more. , so you have to have good perseverance to hold back or not buy it (to put it plainly is to buy you do not have money to buy). There is not a saying in the North American study circle: North American Express Express should be renamed North American Express Mail. In contrast, domestic preferential activities are not so effective.
Another is to buy second-hand, ebay is equivalent to salted fish plus Taobao, when you search the results are mixed, and many are in the form of an auction, if the private seller did not pay attention, the end time in the early hours, then as long as your last second bid , it is very likely to buy things at a very cheap price, whether new or used. Moreover, Americans (non-merchants) sometimes have little idea about the price of second-hand goods. They have poor mathematics (or do they have money to care about?). Sometimes something new can be sold at half price. And the description will not lie to you, because eBay's protection of the buyer is better, and in the case of insufficient evidence, what the buyer said is what. The parcel you said did not receive or did not receive, express delivery service is also useless, something made less transport damage, not on the spot inspection, later you say yes, businesses have to re-issued or returned. If you want to do so many domestic companies have to go bankrupt.
Another worth mentioning is eBay's cashback and roll gift cards. Cash back is about 8% or 10% cash back every month, no matter what shop you are buying (value items, such as coins, gold, cars, etc. do not participate, but a rare purchase of gold can be returned ), more than 50 or 100 knives at the time of settlement can be cashed back. Each time the upper limit is returned to 100 knives, the next quarter will be returned to you with the ebay credit point. The credit point can be used as money in ebay without restriction. But as you know, which gift card can be purchased in ebay, it's basically equivalent to money. In addition, ebay probably has one or two eBay e-Gift Cards sold at discounted prices for one month. The most interesting thing is that you can use the cards you bought before to buy new ones, so that you have been lucky enough to start turning 100 after half a year and change to 200. It's not good to change 200 after one year. This wool won't be too cool. (However, there may be too much bedding. After 16 years, you cannot use a gift card to buy a gift card. You can only buy it with real money)
Monitor Dell P2214H :
Ok, returning to the game, the following began to talk about my display device bought in the United States. How important the monitor is, it doesn’t say anything, play games, watch videos, read course papers, etc. The screen of the original notebook can not meet the requirements. Because the desk structure is wonderful, we can only consider 22-inch products. At that time, only one special product was used. The dell's p2214h, so did not think about how to directly start, starting price of 110 knives, about 700 yuan
Fortunately, with a professional bracket, just put it into the table, just half a centimeter will not work
I bought it from dell's official website. It is said that it is a professional-grade monitor. The adjustable range of the bracket is really good. It can be regarded as a four-axis adjustment and can be erected to read the paper. There are three USB hubs behind it. Because the USB interface of the notebook is not enough, just Lest I buy it separately. Unfortunately, hdmi is not supported, only displayport, but VGA is not useless anyway.
Vertically looking at the paper is still very cool, but unfortunately as the school slag did not see much chance of papers
The gamut just satisfies sRGB, but the color display is very accurate. In general, this dell still won my heart, and it is feasible to sell it to her younger brother before returning home.
The performance parameters tested by myself are still good
Projection 1: Optoma hd131x (domestic model hd25e)
I usually love to watch movies, especially those who love to watch “DUANG, DUANG, DUANGâ€. After a year in the United States, I can’t stand it anymore. U.S. movie theaters don’t add subtitles. I have to ask for subtitles to have glasses, and I used to To wear glasses, plus 3d glasses, think that feels like egg pain (not exactly do not understand, but so tired, do not relax).
Caption glasses, yes, not the same technology as Google Glass
So after confiscating the money in the second year, he decided to start with a legendary projection. (For me, this type of silk is legendary, and if it weren't in the United States, I wouldn't be able to buy it at a cheap price). After a period of understanding, the goal was set on a dlp projection with higher definition and contrast, and more aging resistance. Because the color of the lcd projection is better, but the black is poor, it is easy to aging and hair, or is not suitable for me. Another advantage of dlp is that due to the refresh rate of up to 144hz, it basically supports 3d. In addition, I think that projection of this kind of thing, 1080p no need to consider the following, after all, if the picture quality is not good light screen is also useless.
The machine picture can't be found, just leave a screen shot and check it out.
Not worth the price, is to give you a look just let me recommend, then I would like to say the second projection is more cost-effective, reasons behind said
This is the second-hand goods that I bought on ebay. The 430 knives are backed by 10% cash back. The final price is about 2,400 yuan. At that time, the light bulb time was 156 hours. After the machine arrived, it looked really new. Do you dare to say this price? At that time, the room I rented was about 3.5-4m wide. It could project an 80-inch screen. The brightness of the blinds would be enough to use. The best way to watch movies is to wait at night or on blackout curtains.
Hd131x I probably spent a month and then sold 10% off (equivalent to no money spent for 1 month) for three reasons. First, the upper and lower ends can't always coke up. This seller also said that it is also The reason for the cheap, it really does not matter when watching movies, but the upper blood bar and the lower right corner status bar when playing Wizard 3 is always a little bit of a blemish, but the problem is not big, but I obliged the culprit. The second is that this machine uses the RGBCMY color wheel, although the brightness is high, but the color performance is not as good as the RGBRGB color wheel, while the rainbow effect is more obvious. As the brightness of the home machine does not need to be too high, 2000 is enough. The third is that 80-inch is still too small, plus anyway to sell it without losses (this is also the reason why the United States developed second-hand transactions, as long as you will operate, trading second-hand things do not lose money), so add some money to the previous species Another grass was pulled out.
Projection 2: BenQ ht1075 (domestic model w1070+)
This is a very cost-effective machine. When you checked the data, you knew it, but you didn't wait until the right price. This time it was also used by ebay, with a price of 600 knives, 8% cash back, and about 3400 RMB. Shutter-type 3d glasses are bought separately, 10 tools and 1 pair.
There is no hoisting. Currently on the nightstand, the movies are all lying on the bed and there is no noise.
The domestic package can be considered w1070, almost the same picture quality, but also a few hundred cheaper
This machine basically satisfies all my requirements. The specific parameters are not reported. Look at Jingdong or the official website. Let me talk about some of my own feelings:
The screen is large, and the w1070+ has a larger projection ratio. It can also project a 120-inch screen in my room.
Color accuracy, of course, is not comparable with LCD projection on the color gamut, but it has met the needs of watching movies. In addition to the poor performance of green after debugging, the others are very accurate.
The contrast, black level, and brightness are also sufficient, and the contrast is fully opened at 1132. The rainbow eye is also visible only in rare cases, but it does not affect fleetingly.
The effect of 3D is significant, and the off-screen effect is obvious. The on-screen effect is more significant on the edge of the screen. It feels like a window, and everything inside is outside the window.
In addition, no significant input delay was felt when playing games (including GTA5, fifa15, and shaman 3).
The screen is red, it is a green compensation for the shutter-type 3d glasses, and the glasses are all black
Because she was very satisfied with the effect of the 1070+, after graduation, she worked hard to bring it back from the United States (when she returned home, she hadn’t passed the customs before, but she still worried about being taxed). However, because there is no house of his own, parents did not leave room for projection when the house was renovated. Coincidentally, my bedroom is as wide as the American house, so all are 120-inch. Since my room has just an entire white wall, I just saved the money for the curtain. The effect of the adjustment should not be bad.
Adjusted performance parameters are very accurate except for green
Since the screen shot was influenced too much by the photographic equipment and film sources, I wouldn’t put more to avoid misleading others. Adjusting parameters is also greatly affected by the environment. If there is no professional instrument, my advice is to switch to movie mode, otherwise the adjustment may be worse. Another thing worth noting is that BenQ's projection is easy to get into the gray light. This is true. I have already entered a lot, but I haven't seen any visible influence.
Just put one and everyone will see it.
Finally, there is an advice. If it is not really necessary and there is no money, do not buy domestic led micro-casts. Led projection is the trend of the future, attention is the future, and the success or failure of laser projection is not divided, at this stage the best is the traditional light bulb machine. At this stage, those domestic micro-projections are generally 720p resolution, and below ANSI lumens brightness of 500 lumens (not to mention the peak brightness, that is useless), can only be considered a toy, the effect and the traditional projection of a lot worse. In addition to the so-called only, but is the function of the TV box only, can not be replaced alone does not say, the performance is still relatively poor, not worth buying.
Color correction instrument: Colormunki Display
This, I decided to attribute it to the video, is very relevant. I usually have nothing to do with photography, but just record travel pictures, only to buy a micro-starter (Dafa a5000, fancy it is small, or that there is no money), so I hope to show real when using ps retouching The color, then moved the idea to buy school color instrument. The beginning is to catch a glimpse of the famous spider series, but the spider model's mid-range model does not support projection color correction, so we had to turn to X-Rite's mid-range version, which is the display.
Ontology and counterweights,
Buying 120 knives is considered cheap. However, this is just a colorimeter (reading light into three primary colors). I am sorry to use a more advanced photometer (direct access to the spectrum). The performance parameters of the above display and projection are measured using it, but the software used is not the same. The display is based on Argyll's free software, DisplayCAL, which automatically adjusts the system's icc configuration. The proofreading process does not require manual intervention. HCFR is used for projection, because DisplayCal has a slow correction rate and there are many projection correction parameters that make it difficult to adjust automatically. However, since the screen reads a large area of ​​data, the ANSI contrast ratio is 1:1 (if you know what ANSI contrast is, you know that ANSI contrast is 1:1 when you sample the area). I didn't send tutorials. There are many online courses. If you are interested, you can read this article first. The basic steps are correct.
Correct the working status of the monitor. The head image of the article is to correct the working status of the projector.
I did not save the color data before the correction, but I can tell you that there is a big difference between them. Of course, it is difficult to measure with the naked eye without comparing AB, but it is just as difficult to measure with the naked eye between high-end and middle-end products. Sometimes you spend a thousand pieces in color correction, and you can spend a thousand dollars better than you. The projection effect is better.
At last
The article was written in a hasty manner, but in order to thank everyone for supporting the first article, I still tightened the code, or there are omissions and expressions are not clear, there are questions in the comments can leave a message, these two days I will basically reply . Thanks again for your value, thanks for editing!
