Recently bought a mobile phone projection, half of the reason that the family's lost parents often travel, can be used to see the film, the other half is that they also want to try new smart products, used to see this thing in Aunt Zhang, some People say good, some people say quality slag, and then my experience does not feel ideal, 480p low-resolution picture quality and projection brightness barely able to see the film, let me think of the era before the university RMVB, the current words and high-definition Or the theater is far away, it is recommended that the picture quality party bypass, can only be used to make a temporary substitute to see the film stuff, the following box experience.
Buying a PaPa's mobile phone projection, this is relatively small and portable, but on the contrary, it may also be because of the sacrifice of performance and picture quality. Also bought a tripod and miniHDMI video adapter, PaPa accessories too shabby.
There is nothing to say about the packaging, the simple white paper tray, accessories are a bit tricky, there is no video adapter (because it is not standard HDMI but miniHDMI), there is no mini-tripod.
PaPa's charger is too big and the pins don't support storage. I'd rather have a smaller cell phone charger, anyway.
The remote control is plastic, and its texture is poor. It is very difficult to tear it apart. It does not have a few keys. Considering the original intention of portability, it is better to integrate the keys into the projection box.
PaPa model PA02 mobile phone projection volume is very small, only 85 × 85 × 16.5 (mm), smaller than the millet box number one, looks like Apple's aluminum alloy shell style, work quite satisfactory, there is no flash burr, I think the volume and appearance is The only advantage of this PaPa, the rest is a variety of Tucao.
For example, on this side of the interface, why is this side not using aluminum alloy panels?
There are three interfaces, micro USB charging port, USB plug-in U disk playback interface, and MiniHDMI video interface, why not the mainstream of the HDMI interface, but also took me to spend 7 5 hair to buy a video adapter, really better The useless transparent window cancels out to standard HDMI.
Power switch, cooling hole.
Focus knob, sound hole.
Vents, projection lens, lens concave, not easy to be assigned to, of course, it is best to pack a storage bag, it is said that the use of the world's leading Texas Instruments DLP display technology, mainstream design of similar products, for this projection lamp hardware Performance I do not understand very well, anyway, quality is not satisfactory, not boasting so good.
Internal disassembly chart.
PaPa phone projection does not support trapezoidal correction, must be facing the projection, so in fact it is still necessary to use a tripod to facilitate the adjustment, Tucao again no tripod fixed holes, if lost? So I had to use a clip to fix it.
Usage & Projection EffectThe boot time is a bit long and requires a long press of the power button for a few seconds, then the projection light will turn on for a few seconds.
Boot screen as above, the default slide one line of a simple tutorial, the upper right corner is the power, there is no Android operating system, if the U disk player, mobile phone with screen and HDMI projection, is not wasting the box inside so many chip resources, Looking at the cheaper PA01 is more systematic and does not understand why it was cancelled.
About how to put the mobile phone on the screen to the projection, different mobile phone brands provide corresponding steps, but there are mistakes, such as my old Samsung S4 screen sharing feature is not in the picture album (find for a while, and finally find Baidu ), but in the Settings - Connections menu.
In addition, I do not know whether it is my RP or PaPa compatibility issue. I can't connect it. I even thought that the newly purchased mobile phone projection was bad. S4 obviously detected the PaPa-45C device, but the connection failed, and then changed the ASUS Zenfone2. Not on the last chance to try out the S4 factory reset. Fortunately, it was almost successful and it was almost repaired.
After the connection, not only the screen sharing, the sound is also emitted by the projection box, and the screen can be rotated.
PaPa projection quality really tells the truth, 854 × 480 resolution is really too low, the details of the shadows are not clear, like me after 80 from the era of RMVB people can barely see, 1080P HD party estimated to worry about.
The above is the HDMI connected computer, at this time the resolution is automatically adjusted to 1280×720, the actual course is not so high, in short, look at the web, office and other applications will feel quite painful, PC games are the same, so that is the display is broken and temporarily replaced Use it.
U disk to play, I use the mechanical hard drive + HDD box USB3.0, no problem, 3 partitions can read.
Support mp4, wmv, vob, m2ts and other formats, provide preview function, but does not support mkv, high bit rate 1080p video does not support, such as "eat roast duck" Demo, but support does not make sense, after all, the resolution of the projection was pitiful 480p.
Remote control operation with the video box, is a slow response to the remote control, not used.
The real quality of the picture is good, but the brightness is still acceptable. If it is the environment where the energy-saving lamp is turned on at night, it can still be seen clearly. Grayscale performance is slightly poorer, and the black grid must be distinguished from the back of the 3rd and 4th grids. The color transition is slightly better, and at least it does not feel too obvious.
to sum upPaPa mobile projection theory can project up to 100 inches, but it is not recommended to use such a large projection size the lower the brightness, 1.5 ~ 2 meters is more appropriate projection distance, in other respects, the fan is very quiet, can not hear half a meter away Noise, the surface temperature of the highest point is about 42 °C, this time more than 30 °C room temperature does not open the air conditioning, touch it is not too hot tepid, I do not evaluate the sound quality (I can not go to where it is), there is a battery life, The built-in battery can only hold for about 1 hour. It is not very good but it is not a big problem. Now, there is no one or two large-capacity charging treasures in the hand.
Disadvantages:
Poor picture quality, only 854×480 resolution, barely watching movies or using it as a monitor, office or game saves money.
Does not support trapezoidal correction, there is no tripod fixing hole, placing position seems troublesome
The remote control and charger are relatively large and are not portable
No built-in operating system or APP application software, feeling waste of hardware performance
Built-in battery capacity is low, life is only about 1 hour
1999 yuan price is expensive
advantage:
Aluminum alloy shell, good sales and workmanship
Compact and easy to travel
