问大家
: After buying it, I feel it's a bit blurry and has ghosting, even when projecting straight on. I want to ask how to fix this. 买了之后感觉有些模糊，会有重影即使正着投，想问下怎么解决
: There's a protective film on the lens! It looked exactly like yours before I peeled it off—super clear afterward! 镜头上有个防划贴膜！我没揭掉前和你一模一样！揭掉以后巨清晰
: Hello, first and foremost, thank you very much for your support, and we sincerely apologize for the inconvenience caused. If your product experiences blurring even with direct projection, first, please ensure that your projector is as horizontal as possible and does not shake during projection. If the issue persists, you can try using our manual focus function to achieve a clear state. Regarding the ghosting issue, it's because after the product's automatic keystone correction, it will automatically adjust to project a square area, which may leave some background of the original projection shape. However, this will not affect the viewing experience. We apologize again if it caused you inconvenience, and we will do our best to improve this issue in the future. If you have any other questions, please feel free to contact us or our after-sales team at any time, and we will do our best to solve your problem. 😄😄😄 您好，首先非常感谢您的支持，也对给您带来的困扰表示诚挚的歉意。如果您的产品正投都会产生模糊的情况，首先需要您确保您的投影仪尽可能处于水平状态，且在投影过程中不会有所晃动，如果还存在这种情况，也可以使用我们的手动对焦功能尝试手动对焦达到清晰的状态。 另外关于重影的问题，是由于产品自动梯形校正后，会自动调整选择方形区域进行投影，会存在有部分原投影形状的背景，但是不会对观影造成任何影响呢，如果对您造成困扰我们也再次表示歉意，后面我们会尽可能升级改善这个问题。 有任何其他问题也欢迎随时和我们或者我们的售后团队联系，我们会尽可能解决您的问题。😄😄😄

回复 @jack520yan : There are many, like AiyiFan TV version, New York Cinema TV version, Duboku TV version (these have a few ads); for high definition without ads, you'll need a TV Box app like Moonlight Box Max that offers multiple lines and sources. Just research a bit and you can install them. I directly downloaded the APK file on my phone and pushed it remotely via Dangbei Market to install. 这可太多了，比如爱壹帆tv版，纽约影院tv版，独播库tv版（这些有一两个广告的）；高清得还得弄个tvbox的app而且无广告，比如月光宝盒max这类可以多线多源的，反正研究一下就能安装了，我是直接在手机下载apk文件然后通过当贝市场那个远程推送推过去安装的
: Which one is better, the Boom3 or the Mini? Are they both suitable for outdoor use? boom3和mini哪款比较好 都是可以户外？
: Hello there! We're delighted that you've chosen the Aurzen brand projector~ The Boom mini has several standout advantages in terms of ease of use and outdoor adaptability: First, it comes with the Google TV system built-in, so you can start using it right out of the box without needing additional devices—super hassle-free! Second, its brightness is a genuine 500 lumens, delivering excellent clarity and color performance in dim outdoor settings (like nighttime camping or backyard gatherings). Plus, it features an instant-stop gimbal stand, allowing you to flexibly adjust the projection angle anytime when outdoors. Whether you're projecting onto a tent, screen, or wall, it quickly aligns the image—super convenient! The Boom mini would be a perfect fit~ 😊 您好呀！很高兴您选择Aurzen品牌投影仪~ Boom mini 在使用便捷性和户外适配性上有几个突出优势：首先它内置了谷歌 TV 系统，开机就能直接使用，不用额外连接设备，操作很省心；其次它的亮度是真实 500 流明，在户外较暗的环境（比如夜晚露营、庭院聚会）下，投影的清晰度和色彩表现都很出色；而且它自带即停的云台支架，户外用的时候可以随时灵活调整投影角度，不管是投在帐篷上、幕布上还是墙壁上，都能快速对准画面，特别方便～ Boom mini 会很合适呢～ 😊
: It's probably a mini. Boom3 is not a Google TV system, so you'd still need to buy a Fire Stick to plug in. Or if you only need to cast your screen, it should be fine. 大概是mini，boom3不是Google tv系统，你还得买个fire stick插上去，或者你只需投屏的话，大概可以

Enjoy your new NEBULA projector! For any issues, our team is here to help. 亲爱的顾客，感谢您的反馈与选购！非常抱歉没有及时回复您的问题，关于亮度的问题，我们非常理解不同使用场景对亮度的需求差异。您提到在 eBay 下单了 NEBULA Cosmos Laser 4K 投影仪，相信您一定很期待它的表现～ 如果您在使用我们的投影仪时觉得亮度不足，可能是以下原因导致的，我们为您整理了优化建议： 1.调整使用环境 尽量在较暗的环境中使用（如拉窗帘、关闭强光），减少环境光对画面的影响，亮度视觉效果会更突出。 避免投影仪直射强光光源（如窗户、灯光），以免画面发白。 2.设置中调节亮度参数 3.保持设备散热与清洁 无论您使用哪款设备，若在操作中遇到任何问题，都可以随时联系我们的客服团队，我们会提供专业的解决方案～期待您后续的使用反馈，祝您观影愉快！

: Hello, we sincerely apologize for this situation. Due to Amazon's 30-day no-questions-asked return policy, some returned items may be reassessed and relisted by Amazon. We deeply regret any inconvenience caused, but we guarantee that every unit shipped to Amazon is brand new. Our projector operates at approximately 35dB in Standard mode, 33dB in Eco mode, and 37dB in High Brightness mode (subject to slight variations based on distance). These noise levels are generally lower than most projectors in the same price range! 🎶 You can immerse yourself in the big-screen experience without disturbance. For even quieter operation, we recommend using Standard or Eco mode. 📽😊 您好，发生这样的情况我们非常抱歉，由于亚马逊的30天无理由退货政策，确实存在部分商品用户退货后亚马逊评估重新上架的可能，对您造成的困扰我们深感歉意，但是我们确保我们每一个发往亚马逊的库存都是全新的。我们产品风扇噪音在标准模式下大概35dB，eco模式下33dB，高亮模式下37dB（根据机器与人的距离可能略有差异），通常来说属于较低水平，比同价位的投影仪更安静哦～🎶 观影时基本不会受到干扰，放心沉浸在大屏体验里吧！当然如果您需要更低的噪音，建议可以使用标准或者eco模式观影哦。📽😊
