This year I was assigned to work in a branch office. I originally planned to apply with the Director General to buy a TV room for the dormitory. However, I did not approve it and I was as smart as I was. I simply applied for a projector and I was successful in my life. succeed.
Selected for a long time and found that this projector is a rare projector that supports 100% REC.709 color 4,000 yuan, double 11 decisively purchased, had to say that this Jingdong is still super fast, one day received. The package is very tight, and the bubble bag is wrapped in several layers.
The box of the machine is black with the appearance of the machine.
There is a layer of foam in the box, just stuck in the middle of the machine.
Take out the machine and there is a bag outside.
After the demolition finished, you can see the real body.
ViewSonic this machine lens is recessed design, the light bulb is 240W, economic mode life is 6500 hours, the normal mode lamp life is 3500 hours, because the lens is not a protective lens cover, storage time is best to put on the bag, Avoid dust.
Body with a physical button, you can easily operate the switch, trapezoidal correction and other functions, this machine supports vertical trapezoidal correction, the entire machine is only 2.9kg, relatively light, it is recommended to watch or display is correct, because I How much the trapezoidal correction feels will reduce the quality of the image.
There are two circles on this side. The small circle inside has a protruding gusset plate. Toggle the gusset to turn the small circle to adjust the focal length. The front circle is used to adjust the lens's distance. Manually Adjustment, each time you use may be based on the placement of different, focal lengths need to be adjusted to better use.
The cooling vent of the machine has good cooling effect.
The fan can be clearly seen directly.
The body interface is quite complete: HDMI 1.4 input interface *2, VGA*1, RS-232*1, Audio in, and mini USB typeB*1 can meet the needs of use.
The description of the bottom of the machine, you can simply understand the machine information, there is a row of small heat vents.
Machine instructions, warranty cards, Rec. 709 standard instructions.
The boot screen shows that the color transition of this machine is relatively natural. In the default state and when connecting HDMI resources, the PX725HD defaults to the Rec.709 mode. Switching machine response speed is very fast, 3 seconds boot 0 seconds off.
PX725HD features 1920 x 1080 (1080p) high quality resolution plus 2,000 lumens, no stress during the day
Recently hitting the hunting ground, using the projector to play the screen can see the effect of the day is not bad.
For multi-map warnings, I have looked for graphs of various color types and performed projection comparisons. The above diagrams are all computer display diagrams. The following are all screen projection diagrams.
This is a comparison chart between the screen displayed by the Lenovo notebook computer and that projected by the projector. In the same screen, the screen presented by the projector is more clearly colored.
The dark scene map, the projection screen is also brighter.
On the projection screen of the food, the gloss is better and the food is more lustrous.
to sum up:
The use of the time is not long, in general, the most obvious feeling is the color of this piece, in the Rec.709 mode, plus PX725HD with six-speed RGBRGB color wheel using special coatings to filter RGB spectral segments, the projection screen color is more Rich, while enhancing the hue and saturation, the image color is more smooth and natural. But there is something weird about it. When I came back, I found that there was no signal line. I asked the seller if it was forgotten. The seller said that there was no standard HDMI or VGA signal cable. It is estimated that the manufacturer is to save costs. Fortunately, the dormitory has just the root HDMI cable, or you have to buy another line. Generally speaking, this price can buy REC.709 color gamut projector has been a good deal.
