PVO YG300迷你投影仪的评论

房屋投影仪是几乎灭绝了一段时间的技术之一。然后，像黑胶唱片一样，他们最近卷土重来。就像乙烯基一样，这种疯狂也有很好的解释。看，老派家庭投影仪与现代同行不同。早在60年代和70年代，它们很笨拙，您需要使用卷卷到卷电影。是的，您可以获得出色的视频质量。但这是一个很大，昂贵的系统，这部电影占据了很多存储空间。结果，只有认真的爱好者甚至拥有一位。对于大多数人来说，直到1980年代VHS发明之前，家庭录像都将无法触及。

VHS改变了游戏，因为它负担得起且紧凑。后来DVD和Blu-ray技术也效仿了。使用每种新技术，存储介质都会变得更小一些，并且质量变得更好。通过数字视频和流媒体，我们得出了合理的结论。数字视频除了拇指驱动器或云服务器的一部分外，还占用零物理空间。而且，您可以获得出色的视频质量 - 远胜于VHS的糟糕时代。现在，使用数字媒体，家庭投影仪再次变得可行。您不需要大型电影，也不需要大型框架来安装它们。结果，投影仪不仅可以提供出色的质量 - 它们还可以令人惊讶地紧凑。

Take, for example, the pint-sized projector we’re going to review today: the PVO YG300 Mini Projector. This projector is made first and foremost for portability, and it’s as compact and lightweight as they come. But can good things really come in small packages? To find out, we’ll need to dig a little deeper into how it functions, and what it’s capable of. We’ll start by reviewing the physical design. We’ll talk about how it’s constructed, and how the controls work. Next, we’ll look at the quality of the video itself, as well as the built-in speakers. Last, we’ll talk about how you can connect to the projector, and any extra features it offers. At that point, we’ll have a more complete picture. Let’s begin!

设计与控制

这PVO YG300迷你投影仪is a tiny projector that measures 5.6 inches wide, 3.7 deep, and 2.1 thick. That’s about the size of a paperback book, which is truly remarkable for a fully-functional projector. It weighs only 11.2 ounces, which is fairly light, even for the small size. This makes it very easy to carry around. You can drop it in your laptop bag or backpack and you’ll hardly even notice you’re carrying it. The case has a two-tone design, with orange-gold on the right third and off white on the rest. There’s also an off white PVO logo on the top, directly over the lens.

这lens is housed in the gold part of the case, and doesn’t protrude very far. In fact, the black lens housing only extends by about a quarter inch, and the lens itself is slightly recessed. This keeps the glass well-protected, both from bumps and from scratches. The controls are located on the top left of the housing, and consist of a row of plastic buttons. These are solid buttons that provide good tactile response, not merely soft touch controls. You can use the physical controls to turn the system on and off, play or pause your video, or skip tracks. There’s also a menu for more advanced functions, and for fine-tuning the quality of the image.

In the sides of the housing, there are horizontal slats to allow for air flow. There are additional slats in much of the back of the housing, providing additional flow. They do a surprisingly good job considering the small housing size. Just keep your hands free of the lens area while the projector is running. And give it a few minutes to cool off before storing it away. One thing you won’t find on this housing is any kind of keystone adjustment dial. This was disappointing, since it makes placement a little more complicated. Unless the projector is roughly perpendicular to the screen, you’ll see some distortion.

在房屋的右侧，在顶部附近，有三个端口。从正面到后，有一个USB端口，一个HDMI端口和一个圆形直流电源端口。在外壳的背面，有一个3.5毫米AUX端口，一个AV端口和3向RCA适配器的插头。就在此上方，您将看到SD卡插槽以及附加的USB端口。该端口是一个可选的电源端口，我们将在几分钟内进行更多讨论。

Along with the projector itself, you get a handful of accessories to help you get started. First, there’s an infrared remote, which does everything the main controls do. This makes it easy to pause your video without walking over to the projector. The kit also includes a power cord, an HDMI cord, and an RCA adapter for your older devices. This is actually pretty comprehensive, and should cover most of your accessory requirements.

也就是说，假设您想要一个也带有屏幕的投影仪。在这种情况下，Goodee W80是一个合理的选择。它有一个超亮灯泡，非常适合大房间，并且包括自己的屏幕。也就是说，这是一台全尺寸投影仪，因此不如YG300那么便携。

视频质量

当您购买投影仪时，您不需要考虑一个而是两种不同的视频分辨率。第一个是本地分辨率 - 投影仪能够显示的分辨率。第二个是支持的分辨率 - 您可以投入投影仪的分辨率。在这种情况下，YG300的支持分辨率为1080p，本机分辨率为800 x 480。

这实际上并不令人印象深刻。假设您正在玩DVD，分辨率为1080p或1,920 x 1,080像素。它只会以800 x 480的速度播放，或小于四分之一的像素数。公平地说，1080p的投影仪很少。但是如今的行业标准是720p；这是超过YG300的480p分辨率的削减。不仅如此，灯光只有足够明亮的地方，可以在黑暗的房间中使用。这也非常适合后院电影之夜。但是，如果有环境光，自然或其他方式，则图像可能看起来昏暗。

与大多数投影仪一样，您可以通过调整到屏幕的距离来更改屏幕尺寸。总共可以从最小25英寸到最多152英寸。在对角线上超过12英尺！这对应于距屏幕50到150英寸之间的距离。在这些范围之外，您的图像将开始变得模糊。

那么，如果您想要具有更好视频质量的投影仪，该怎么办？如果那是您想要的，请考虑Vilinice 5000L迷你户外电影投影仪。它类似地轻巧和紧凑，本机分辨率为720p，颜色更具活力。它仍然不是很明亮，但这比其他任何东西都更重要。

兼容性和附加功能

那么，您可以使用哪些类型的输入来播放视频？首先，有HDMI端口。这是默认选项，这是您将用于大多数现代设备。如果您使用的是DVD播放器，蓝光播放器或游戏控制台，那将是您的首选。也就是说，有许多设备没有HDMI作为一种选择。在这种情况下，您也可以使用简单的AV电缆。使用随附的分离器，您还可以接受RCA设备的AV信号。这将涵盖VCR和较旧的游戏机。如果您想与PlayStation 2一起度过一个复古的游戏之夜，可以。

Another option is to use the USB port. You can easily plug in a thumb drive or external hard drive to watch your movies that way. You can also use smartphones that support USB-connected displays. So you can stream Netflix from your phone directly to the projector screen. The last option is to use the SD card. This is ideal for home videos, whether from your phone or from a dedicated camcorder.

YG300的内部扬声器具有能力，但相对较小。声音听起来不错，但是您将无法充满噪音。除非您自己悄悄看电影，否则您将想要一套更有能力的扬声器。值得庆幸的是，您可以插入3.5毫米AUX端口并从那里获取信号。这使得设置大多数扬声器变得容易。也就是说，没有WiFi或蓝牙功能。结果，无法使用不支持有线连接的蓝牙扬声器。

根据您的声音设置，这可能不是一个问题。但是，如果您需要蓝牙支持，则有选项。拿Wimius S25， 例如。它不仅支持蓝牙扬声器，还支持通过蓝牙从手机铸造的。不仅如此，它的720p天然分辨率优于YG300。

One thing the YG300 offers that most other projectors don’t is an alternative power option. You can run it from any USB power supply, with a minimum of 5 volts, 2.5 amps. That’s slightly more than the standard of 5 volts, 2.4 amps. But there are plenty of USB power banks that provide considerably more.

最终判决

总而言之PVO YG300迷你投影仪有点混合袋子。它的主要好处是它的可移植性 - 即使在飞机上，您也可以将其带到任何地方。在这方面，这几乎是无与伦比的。不利的一面是，质量比我们对现代投影仪的预期要少。即使是720便士，这将是一个重大改进。
