手机屏幕投影到投影仪_投影机与大屏幕电视：您应该购买哪一个？
手机屏幕投影到投影仪
You don’t have to have a dedicated home theater room to justify using a projector. Flat-screen televisions have been getting bigger and cheaper every year, but projectors can still produce a much larger image for a lot less money! Given the similarities between the two, that raises the question: Should you buy a projector or a TV?
您不必拥有专用的家庭影院室即可使用投影仪证明其合理性。 平面电视每年都在变得越来越大和便宜，但是投影仪仍然可以以更少的钱产生更大的图像！ 鉴于两者之间的相似性，这引发了一个问题：您应该购买投影仪还是电视机？
图像尺寸：大，更大，最大 (Image Size: Big, Bigger, Biggest)
Let’s be honest: Size does matter! Bigger is usually better if you have the wall space when it comes to image size. Whether you are watching movies, bingeing TV shows, or playing your favorite video game, it’s easier (less strain) on the eyes when the picture is huge. This single feature of projectors can outweigh any detractors for most people.
老实说：大小很重要！ 如果在图像尺寸方面有墙面空间，通常更大会更好。 无论您是看电影，狂暴地观看电视节目还是玩自己喜欢的视频游戏，当图片很大时，对眼睛来说都更容易(减轻压力)。 对于大多数人来说，投影机的这一单一功能可以胜过任何不利因素。
Almost as important is that the image size on a projector is variable! Every projector has an image size range that it supports. Moving the projector farther from the projection surface makes the image larger. Moving closer makes it smaller.
投影机上的图像大小可变几乎同样重要！ 每台投影机都有其支持的图像尺寸范围。 将投影机移离投影面越远，图像越大。 靠近会使其更小。
The supported image size range is determined by the optical focus ring. If you are in a small apartment, just move the projector closer to the wall. But the same projector can display a massive image on the side of a building.
支持的图像尺寸范围由光学对焦环确定。 如果您在小公寓里，只需将投影机移近墙壁即可。 但是同一台投影机可以在建筑物侧面显示大量图像。
The same can’t be said for a big-screen TV, which has a fixed image size relative to the size of the screen.
大屏幕电视的图像大小相对于屏幕大小是固定的，但不能说相同。

图像质量：万物不平等 (Image Quality: All Things Are Not Equal)
The challenge with projectors has always been with picture quality—contrast and color accuracy. The contrast between light and dark can be significantly degraded with ambient light or a poor projection surface. But direct light can cause a reflective glare problem for many TVs, which can be even more annoying.
投影仪面临的挑战一直是图像质量-对比度和色彩准确性。 周围光线或不良的投影表面会严重降低明暗之间的对比度。 但是直射光会导致许多电视反射眩光，这可能会更令人讨厌。
Color accuracy for large projection displays is also a challenge. LCD projectors typically do a better job of presenting accurate color, but the LCD pixels are also amplified by the large display surface causing a screen-door effect. DLP projectors use a spinning color wheel to manufacture color, often at the cost of some color accuracy.
大型投影显示器的色彩准确性也是一个挑战。 LCD投影仪通常会更好地呈现准确的颜色，但是LCD像素也会因较大的显示表面而放大，从而产生屏幕门效应。 DLP投影仪使用旋转的色轮来制造颜色，通常会牺牲一些颜色精度。
LCD and LED big screen televisions also have individual pixels, but the pixel size is designed so that they are small enough to maintain a sharp image given the size of the display. Because the image size does not change, the tiny space between pixels is not amplified into the screen door effect unless you are viewing from an extremely close position.
LCD和LED大屏幕电视也具有单独的像素，但是像素尺寸设计成使得它们足够小以在给定显示器尺寸的情况下保持清晰的图像。 由于图像大小不会改变，因此除非您从非常近的位置观看，否则像素之间的微小空间不会放大到屏幕门效果中。

灵活的位置和便携性：一个非常便携，一个不便携 (Flexible Position and Portability: One Is Very Portable, One Is Not)
Most projectors support both front projection and rear projection. Rear projection is a nice option because the projector can be hidden if you have space to mount it behind the screen. While many projectors need to be many feet away from the projection surface, short-throw projectors, such as the Vava, can be placed on a credenza or other narrow surface just inches away from the wall.
大多数投影仪都支持正投和背投。 背投是一个不错的选择，因为如果有足够的空间将投影机安装在屏幕后面，则可以将其隐藏。 尽管许多投影仪都需要与投影表面相距几英尺远，但是可以将短投投影仪(例如Vava)放置在离墙壁仅几英寸远的书架或其他狭窄表面上。
All projectors can be moved much more easily than flat-panel televisions. The same projector that is your daily driver for movies and gaming inside the home is by its very nature a portable projector, and can easily be taken outside and placed on a table, projecting on a simple white sheet for a neighborhood movie night. You can’t do that with a big-screen TV!
与平板电视相比，所有投影机都可以轻松移动。 从本质上讲，同一台投影仪是您日常在家中观看电影和游戏的驱动程序，它实际上是一台便携式投影仪，可以轻松地带到室外并放在桌子上，投影在一张简单的白板上，用于附近的电影之夜。 大屏幕电视无法做到这一点！

图像分辨率vs.尺寸vs.成本：选择任意两个 (Image Resolution vs. Size vs. Cost: Pick Any Two)
These days, the industry-standard is 4K resolution. Producing a 4K image from a projector is not an easy task. Native 4K projectors exist, but their cost is at the high end of the spectrum. Most value-oriented projectors are not native 4K. Instead, they are native 1080p images that are pixel shifted.
这些天，行业标准是4K分辨率。 从投影仪产生4K图像并非易事。 存在原生4K投影仪，但其成本处于高端水平。 大多数以价值为导向的投影机不是本机4K。 相反，它们是经过像素移位的原始1080p图像。
By moving the 1080p image around in four positions so fast that the human eye can’t tell the difference, a 4K image is perceived. Unless you look at a pixel-shifted 4K image and a native 4K image side-by-side, most people won’t notice a difference. But a native 4K image is superior in direct comparison, especially at a larger screen size.
通过将1080p图像快速移动到四个位置以至人眼无法分辨出差异，就可以感知到4K图像。 除非您同时查看像素移位的4K图像和本机4K图像，否则大多数人不会注意到它们之间的差异。 但是原生4K图像在直接比较中表现出色，尤其是在更大的屏幕尺寸下。
Today, native 4K televisions are relatively inexpensive up to about 65 inches, with the largest of the “affordable” bunch going up to 85 inches and cost quickly going up from there. There is a niche segment of extremely large flat-panel TVs that can go up to 120 inches or more. But then the issue becomes deciding to spend your money on one of these massive flat panels or that luxury sports car you always wanted. It’s the same amount of money.
如今，原生4K电视的价格相对便宜，可达到65英寸左右，而“负担得起的”电视中的最大电视可达85英寸，并且成本很快就上升了。 超大尺寸平板电视的细分市场可能高达120英寸或更大。 但是，问题就变成了决定将钱花在这些大型平板显示器之一还是您一直想要的豪华跑车上。 钱是一样的。
Flat-panels have another advantage in that they are always on the cutting edge of display technology. While projectors are having a hard time bringing native 4K to the value segment, flat panels are already starting to display 8K resolution!
平板的另一个优点是，它们始终处于显示技术的最前沿。 虽然投影仪很难将原生4K引入价值领域，但平板显示器已经开始显示8K分辨率！

刷新率和游戏：投影机无法挂起 (Refresh Rate and Gaming: Projectors Can’t Hang)
The minimum refresh rate found on displays today is 30Hz. It’s not awesome. A 60Hz refresh rate is pretty good for watching television and movies, but gaming is a different story entirely. Ideally, we want screen refresh rate to be higher—120Hz or 144Hz or more!
今天在显示器上发现的最小刷新率是30Hz。 太棒了 60Hz的刷新率非常适合观看电视和电影，但是游戏则完全不同。 理想情况下，我们希望屏幕刷新率更高-120Hz或144Hz或更高！
Most projectors can’t do that, particularly in the value segment. It’s already hard enough for them to hit 60Hz while shifting the pixels to produce the 4K image. Meanwhile, there are flat-screen TVs on the market that already boast compliance with the HDMI 2.1 standard supporting 8K at 60Hz or 4K at 120Hz. Combine that with an Xbox Series X, Xbox Series S, or Playstation 5 that will all support a 4K signal at 120Hz while also rendering 120fps, and you have gaming nirvana!
大多数投影仪无法做到这一点，尤其是在价值细分市场中。 在移动像素以产生4K图像的同时，它们已经很难达到60Hz。 同时，市场上已经有符合HDMI 2.1标准的平板电视，它们支持60Hz时8K或120Hz时4K。 将其与Xbox Series X，Xbox Series S或Playstation 5结合使用，它们都将支持120Hz的4K信号，同时还可以渲染120fps，这就是游戏必杀技！
From a gaming perspective, the higher the framerate and the higher the refresh frequency, the smoother the image will render on the screen. Odds are, you don’t know what you are missing. But the first time you see 120fps and 120Hz refresh, you will never want to go back to “just” 60fps or 60Hz!
从游戏角度来看，帧速率越高，刷新频率越高，图像将在屏幕上呈现的越平滑。 奇怪的是，您不知道自己缺少什么。 但是，第一次看到120fps和120Hz刷新时，您再也不想回到“仅” 60fps或60Hz了！
Another important feature of HDMI 2.1 is Variable Refresh Rate (VRR), which those same next-generation game consoles and several new flat-screen displays will support. VRR allows the console and the display device to work together to harmonize the screen refresh rate with the game rendering frame rate to eliminate screen tearing.
HDMI 2.1的另一个重要功能是可变刷新率(VRR)，那些相同的下一代游戏机和几个新的平板显示器将支持它们。 VRR允许控制台和显示设备一起工作，以使屏幕刷新率与游戏渲染帧速率保持一致，从而消除屏幕撕裂。
Screen tearing happens when the rendered image frame is being refreshed by the monitor at the same time it’s being redrawn by the 3D-rendering engine. This happens when the refresh rate and the rendered frame rate (fps) are not the same. The result is that for an instant, the screen is showing parts of an image from multiple frames at the same time. While brief, it is an unpleasant artifact. VRR eliminates this artifact by synchronizing the screen refresh with the rendering rate (fps) of the game console or graphics card.
当显示器在3D渲染引擎重新绘制渲染的图像帧的同时刷新屏幕时，就会发生屏幕撕裂。 当刷新速率和渲染帧速率(fps)不同时，会发生这种情况。 结果是，屏幕瞬间同时显示了多个帧中的一部分图像。 虽然简短，但这是令人不愉快的人工产物。 VRR通过将屏幕刷新与游戏机或图形卡的渲染速率(fps)同步来消除这种伪影。
So if there is a lot going on in a particular “scene” and the console is only able to achieve 80fps, the display device can match the appropriate refresh rate to ensure that every frame of the motion video is still cohesive. Once again, flat screens are definitely ahead of projectors by supporting HDMI 2.1 and VRR features, and hardcore gamers might not be willing to give that up.
因此，如果在特定的“场景”中发生了很多事情，并且控制台只能达到80fps，则显示设备可以匹配适当的刷新率，以确保运动视频的每一帧仍然具有凝聚力。 再次通过支持HDMI 2.1和VRR功能，纯平显示器绝对领先于投影仪，而铁杆游戏玩家可能不愿意放弃。

底线：没有错误的答案 (Bottom Line: There’s No Wrong Answer)
It’s easy to think that flat panels boast a superior feature set than projectors, and in some ways they do. But the performance differences are generally small. Modern projectors are VERY capable devices. Projectors go a long way to present an amazing viewing experience at the expense of a few features that they can’t yet support at a reasonable cost.
容易想到，平板显示器比投影仪拥有更出色的功能，并且在某些方面可以做到。 但是性能差异通常很小。 现代投影仪功能非常强大。 投影仪以无法提供合理价格的一些功能为代价，可以提供令人赞叹的观看体验，而且还有很长的路要走。
If you are a hardcore gamer and thinking about buying a display device that will enhance your next-generation gaming experience, then you should be looking for a flat-screen TV that supports HDMI 2.1, VRR, and at least a 120Hz refresh rate.
如果您是硬核游戏玩家，并且正在考虑购买可增强下一代游戏体验的显示设备，那么您应该在寻找一台支持HDMI 2.1，VRR和至少120Hz刷新率的平板电视。
But for everyone else who spends more time watching movies and television shows with only occasional gaming, you simply can’t beat the pleasure of a massive projected image! Home theater projectors may lag behind a bit in technology compared to flat screens, but the important features eventually make their way in. I’m sure we’ll see 4K and 8K resolutions with 120Hz refresh rates in mainstream projectors soon enough. The next-gen gaming consoles will likely encourage that to happen sooner rather than later.
但是对于其他每个人来说，花更多时间仅在偶尔玩游戏的情况下看电影和电视节目的人，您根本无法享受到巨大的投影图像带来的乐趣！ 与纯平屏幕相比，家庭影院投影机在技术上可能会落后一些，但重要的功能最终会逐渐普及。我敢肯定，主流投影机很快就会看到120Hz刷新率的4K和8K分辨率。 下一代游戏机可能会鼓励这种情况早日发生，而不是晚些时候发生。
In the meantime, my wife and I spend our evenings gazing upon 100-inches of beautiful 4K screen space projected by our BenQ TK850, which cost us less than $1,500. We love every minute of it!
同时，我和我的妻子整晚都凝视着BenQ TK850投影的100英寸漂亮的4K屏幕空间，花费不到1,500美元。 我们爱它的每一分钟！
