WIRED Rating: 6/10 WIRED 评分：6/10
GREAT: Great for golf simulation. Continuous operation. Light and portable. Affordable. Easy to configure using the remote. 优点： 非常适合高尔夫模拟；支持连续运行；轻便易携；价格实惠；使用遥控器即可轻松配置。
TIRED: No built-in smart TV OS. Outdated HDMI ports. Passable performance for home entertainment and gaming. Confusing remote for everything but the initial setup. 缺点： 没有内置智能电视系统；HDMI 接口过时；家庭娱乐和游戏表现平平；除初始设置外，遥控器操作逻辑令人困惑。
Indoor golf simulators aren’t easy to set up, and they aren’t inexpensive. It starts with a home cinema projector, but you also need a wide, open space for swinging clubs, a backdrop with netting, and a gaming laptop or desktop to run the software. I was on a mission to see if I could do this much more cheaply with an affordable projector. 室内高尔夫模拟器的搭建既不容易，也不便宜。它不仅需要一台家庭影院投影仪，还需要宽敞的挥杆空间、带有防护网的背景幕布，以及运行软件的游戏笔记本或台式机。我的任务是看看能否通过一台价格实惠的投影仪，以更低的成本实现这一目标。
I accomplished my goal successfully by building around the Optoma GT2400HDR short-throw projector. I skipped the most expensive components, like the backdrop and the clubs. Instead, I used a gaming laptop and controller I already owned, and played EA Sports PGA Tour, which is included with my PC Game Pass Ultimate account. While the projector isn’t a bad option for playing golf at home on the cheap, it’s not ideal for watching movies and TV shows. It also struggles with high-octane games, and it doesn’t even include a smart TV platform. 我以 Optoma GT2400HDR 短焦投影仪为核心，成功实现了目标。我省去了背景幕布和球杆等最昂贵的组件，转而使用我现有的游戏笔记本和手柄，游玩了包含在 PC Game Pass Ultimate 订阅中的《EA Sports PGA Tour》。虽然这款投影仪是低成本居家高尔夫体验的不错选择，但它并不适合观看电影和电视节目。它在处理高强度游戏时也显得吃力，且没有内置智能电视平台。
Made for Indoor Driving Ranges
专为室内练习场打造
Optoma describes the GT2400HDR as a laser-based short-throw projector designed for gaming, entertainment, and golf simulation (the latter being my main intention). It can project a screen size from 30 to 300 inches at Full HD 1080p (1920 x 1080) resolution. My goal in creating an indoor driving range was to keep costs as low as possible, so I planned to use my Xbox controller with a gaming laptop and play on a 100-inch screen while still feeling like I was out on the links. For a golf game, you can get by with a midrange computer or even use a golf sim app on your iPad. (To do that, you’ll need to cast to a device that supports AirPlay or connect through HDMI via an adapter.) Optoma 将 GT2400HDR 描述为一款基于激光技术的短焦投影仪，专为游戏、娱乐和高尔夫模拟（后者是我的主要目的）而设计。它可以在全高清 1080p (1920 x 1080) 分辨率下投射 30 到 300 英寸的画面。我打造室内练习场的目标是尽可能降低成本，因此我计划使用 Xbox 手柄连接游戏笔记本，在 100 英寸的屏幕上游玩，同时依然能获得身临球场的感觉。对于高尔夫游戏，中端电脑甚至 iPad 上的高尔夫模拟应用就足够了。（若要使用 iPad，你需要投屏到支持 AirPlay 的设备，或通过转接头进行 HDMI 连接。）
For less than $1,300, the GT2400HDR is a reasonable option, especially since it works well as a basic golf sim and costs far less than 4K models that can run $5,000 or more. The GT2400HDR also has some interesting perks that make it ideal for long golfing sessions. GT2400HDR 的售价不到 1,300 美元，是一个合理的选择，尤其是考虑到它作为基础高尔夫模拟器表现良好，且价格远低于售价 5,000 美元以上的 4K 机型。GT2400HDR 还具备一些有趣的优势，使其成为长时间高尔夫练习的理想之选。
For starters, it’s rated for 24/7 continuous operation. That’s because the laser light source doesn’t need to cool down after a few hours and can last 30,000 hours total. (Optoma does recommend powering the unit off when not in use, though.) The laser light source does not use a bulb, so there is nothing to replace. Heat dissipation is amazingly good, as the projector tends to run cool, unlike some high-end models. The GT2400HDR has an IP6X dust rating, so it’s sealed better than some massive home theater projectors that cost $4,000—ironic, considering that if you’re spending that much, you would expect better dust protection. 首先，它支持 24/7 连续运行。这是因为激光光源不需要像灯泡那样在运行几小时后冷却，总寿命可达 30,000 小时。（不过 Optoma 建议在不使用时关闭设备。）激光光源无需更换灯泡，因此没有耗材。其散热性能极佳，运行温度较低，这与一些高端机型不同。GT2400HDR 拥有 IP6X 防尘等级，其密封性甚至优于某些售价 4,000 美元的大型家庭影院投影仪——考虑到如果你花了那么多钱，本应期待更好的防尘保护，这确实有些讽刺。
The projector’s light weight (just under 7 pounds) and portability make it a good match for golf simulation. I found it easy to position the projector on the floor and then use it on a table or even in another room without lugging it around like a massive brick. 该投影仪重量轻（不到 7 磅），便携性使其非常适合高尔夫模拟。我发现将投影仪放置在地板上，或者移到桌子上甚至另一个房间使用都非常容易，不必像搬运笨重的砖块一样费力。
I first had to figure out where to place it for the golf sim, though. As a short-throw projector, it should normally sit about 4 feet away from the screen. Since I wouldn’t be using actual golf clubs, I could set it on the floor in my windowless testing room; otherwise, I would have to mount it on the ceiling, away from swinging clubs. The projected image looked big enough that, when I started playing EA Sports PGA Tour, the players looked about as tall as they are in real life. 不过，我首先得确定高尔夫模拟时的摆放位置。作为短焦投影仪，它通常应放置在距离屏幕约 4 英尺的地方。由于我不使用真实的高尔夫球杆，我可以把它放在无窗测试室的地板上；否则，我就必须将其安装在天花板上，以避开挥杆区域。投射出的画面足够大，当我开始玩《EA Sports PGA Tour》时，游戏中的球员看起来和真人差不多高。
I noticed Optoma offers an app to help with initial setup, but it’s a hassle to use. You have to install the app and sync over Bluetooth, but I found it was easier to just do the keystone adjustment with the included remote. (Also, Optoma did not include the required Bluetooth dongle even though it is normally part of the package.) 我注意到 Optoma 提供了一个辅助初始设置的应用程序，但使用起来很麻烦。你必须安装该应用并通过蓝牙同步，但我发现直接使用附带的遥控器进行梯形校正要简单得多。（此外，尽管蓝牙适配器通常是包装的一部分，但 Optoma 并没有附带它。）
Fortunately, keystoning was easy with the remote because, during setup, you can just position the four corners of the image. I ran one HDMI cable for my laptop and one for an AV receiver for surround sound (I used a Yamaha RX300A). In less than 30 minutes, I had the projector running, and I was swinging with the pros at Augusta. 幸运的是，使用遥控器进行梯形校正非常简单，因为在设置过程中，你只需调整图像的四个角即可。我连接了一根 HDMI 线用于笔记本电脑，另一根连接到 AV 接收器以实现环绕声（我使用的是雅马哈 RX300A）。不到 30 分钟，投影仪就运行起来了，我已经在奥古斯塔球场与职业选手们一起挥杆了。
I will say, I had an absolute blast with the setup. I loved the massive screen for golf, and I was pleased I didn’t have to bother with golf clubs, a backdrop screen, netting, or anything else to replicate the experience. If you want to use real clubs and balls, there are quite a few golf sim apps like SkyTrak for both PC and tablets that scan your motion and render a virtual player, although the total cost can add up quickly, including the backdrop and other gear. 不得不说，这次搭建过程让我玩得非常开心。我喜欢高尔夫的大屏幕体验，也很高兴不必为了复刻这种体验而去折腾高尔夫球杆、背景幕布、防护网或其他东西。如果你想使用真实的球杆和球，市面上有很多像 SkyTrak 这样适用于 PC 和平板电脑的高尔夫模拟应用，它们可以扫描你的动作并渲染出虚拟球员，尽管算上背景幕布和其他装备，总成本会迅速增加。
Even though I was using a controller to play a video game, I still felt like I was on the links because of the massive size, bright 4,200-lumen rating, and colorful picture. 尽管我只是用手柄玩电子游戏，但得益于巨大的屏幕尺寸、4,200 流明的亮度以及色彩丰富的画面，我依然感觉自己置身于高尔夫球场上。
The GT2400HDR only runs at 1080p resolution, but it does so at low latency (only 8.4 milliseconds at 120 Hz). I wasn’t expecting home cinema quality at this price, and golf simulations don’t require subtle color variations like a theatrical movie, which might have scenes that take place at night. You need accurate greens and blues, and the GT2400HDR handled that well. GT2400HDR 的分辨率仅为 1080p，但它具备低延迟特性（120Hz 下仅为 8.4 毫秒）。在这个价位上，我并没有期待它能达到家庭影院级的画质，而且高尔夫模拟也不像电影那样需要细腻的色彩过渡（电影中可能会有夜间场景）。你需要的是准确的绿色和蓝色表现，而 GT2400HDR 在这方面表现良好。
There are two HDMI ports, which is fairly common, but the projector does not support the latest HDMI 2.1 standard for eARC passthrough audio. That means no Dolby Vision, and if you connect an AV receiver, you could run into compatibility issues. For example, I tried using my Onkyo receiver and had some minor audio glitches. 它配备了两个 HDMI 接口，这很常见，但该投影仪不支持用于 eARC 音频传输的最新 HDMI 2.1 标准。这意味着它不支持杜比视界（Dolby Vision），而且如果你连接 AV 接收器，可能会遇到兼容性问题。例如，我尝试使用我的安桥（Onkyo）接收器时，就出现了一些轻微的音频故障。
The projector also doesn’t support Wi-Fi unless you add a streaming device like a Google TV or an Amazon Fire TV. It has a legacy VGA port if your device is still in the dark ages (e.g., an extremely old computer, but in reality it is still widely used for signals). 该投影仪也不支持 Wi-Fi，除非你外接一个流媒体设备，如 Google TV 或 Amazon Fire TV。它还保留了一个老式的 VGA 接口，以备你的设备仍处于“黑暗时代”（例如极其老旧的电脑，但实际上它在信号传输中仍被广泛使用）。
