Reasons to purchase A few days ago, this ViewSonic Pro7827hd was launched. Before it had been tangled with whether to buy a TV or a projector, I always wanted to have a large-size screen. The paradox was that the effect of the projection was definitely not as good as TV, but the price of the large-size LCD screen was as good as we were. Suspenders can't afford it. After thinking about it again and again, I bought the projector. Afterwards, I will consider the LCD TV afterwards. Turn it off when I look. I will not go into details when I go out of the box. The protection of the machine is well received. I don't plan to throw away this bubble, but I might use it later. Accessories include: a remote control, a power cord, a VGA cable, a manual with two 7 batteries, praised by the battery. There is also a rectangular box containing a cable box. Right above the machine, the left cover can be opened and wireless modules can be added. The overall material is metal wire drawing, which looks better than baking paint. The cable box can block the messy wiring at the rear and has a beautiful appearance, but it is only used when the ceiling is suspended. The LOGO is reversed. I took a look and took it apart, because I put it on the table and if it is often suggested to be wired it will not be installed. By the way, useful parameters, it is 1080p resolution, 2200 lumens, DLP light source, own sound (good results) Back interface list, if you insert the HDMI cable, you do not need to insert the audio cable, but that several old interfaces do not use. There is a heat sink on this side, which will block the screws of the wireless module. Fortunately, I do not use the wireless module. Businesses can use mobile phones, laptops, and app controls, and they can play the content of mobile phones in real time, without wiring. However, I do not have this demand, it is estimated that the ball needs this place. Projected images can be adjusted up and down using this lens shift. The focus of the lens can go directly to the focus ring above. Personal habits manually adjust. The frontal appearance, it is worth mentioning that there is a rotating rod at the bottom of the machine, you can set up the projector to lift the lens, it is suitable for use on the table. startup screen Try it out with 2 different movie sources: Hobbit (1080p) Mars Rescue (720p) Feeling 1080p video is not much clearer than 720p, but subtitles still reflect the difference in resolution. The knob on the lens can adjust the height of the screen up and down, and can adjust the height of about plus or minus 500px. In front of the scene is off the lights, this is the case after turning on the lights, so during the daytime viewing as far as possible to pull the curtains, turn off the lights at night, 2200 lumens is not very bright, subject to greater ambient light, but the use of this light when the eye damage It should also be relatively small. (Please ignore the hooks on the wall, then the curtain will be installed) The lower right corner of the button on the projection body - color mode can quickly adjust the color mode A total of 5 color modes: highlight, dynamic, standard, sRGB, rec.709 The main color mode of this projector is the color standard of rec.709. Then I try to see the difference between the five modes: Highlight dynamic standard sRGB Rec.709 Personal feeling for this projector standard mode and rec.709 mode is a more appropriate viewing mode of the color mode, I am not a photographer drafting division I do not see any big difference, tune into the family viewing video rec. 709 or standard is enough. to sum up This projector is still a comparative value to buy, in the case of color image definition is clear, some small features are more humane, such as the lens up and down adjustment knob, the bottom of the fuselage pole, a key to adjust the colormode, in addition to trapezoidal I will not mention the correction, because the wall is still large and does not require trapezoidal correction, after the correction will be reduced accordingly. However, the wireless module is a tasteless feature that requires extra money to purchase, and it is very inconvenient to install. The terminal also needs a dedicated download app to use. The general family does not need this thing. Why not plan this area to be more practical? Features?
