Optoma UHD38x True 4K UHD Gaming Projector, Lamp, Standard Throw

I was replacing an Infocus SP7205 projector (720P picture quality) from 2004. Wow, what a difference. I was saving up to actually purchase an Ultra Short Throw Optima projector but the one I had planned on purchasing was discontinued. I already had some wiring from the old projeector in place but had to run a high-speed HDMI cable to the projector location to get the best quality. Man, and this projector projects picture quality. I went back and forth as to which model to purchase because my old projector was 13 feet from the screen in my home-theater. Most projectors have a shorter throw so I wasn't sure if I could use this. My basement has about a 3 foot bulkhead just behind the seats and the old project was at the back of te bulkhead plus it had more of a zoom to set the size to the screen. So I wasn't sure about the distance. Figured I would get this, try it, and if it didn't work, I could return it. Plus this projector was less expensive that the Ultra Short Throw. So I received the projector and couldn't wait to hook it up and see the quality. Picture was perfect. I was able to attache a ceiling mount (not included) to this unit and mount it upside-down on the ceiling. Had to adjust for keystone and I was just amazed. I've had it for a couple of months now and still, every time I turn it on I think to myself, "AMAZING". Brightness is great even with ambient light. Plenty of adjustments for whatever you need. Just make sure to get a high-quality cable. I needed a 25 foot cable and wanted to make sure the signals were strong enough when they got to the projector. True 4K. The only thing that I wish was a little better is that the remote needs to be pointing directly towards the projector. Te senso on the projector requires that the remote be pointing directly at it. This is a tiny issue since you only need the remote to turn it on/off (after initial setup). I couldn't be more pleased with this purchase and I think anyone who purchases this will undoubtedly be happy with the results. Way to go Optoma.

I purchased the Optoma UHD38x in July 2023. Picture quality was excellent initially, but reliability has been extremely poor. Within the first year, the projector developed a DMD dead pixel issue and was repaired by Optoma under warranty. Roughly a year later, the same dead pixel issue occurred again. Although the warranty had expired, Optoma made a goodwill exception and repaired it a second time. Less than six months after that second factory repair, the projector developed the same DMD pixel failure for a third time, and the issue continues to worsen. Optoma has stated that repeated DMD failures are typically caused by either external laser exposure or poor heat dissipation. This projector has only ever been used in a standard home environment with no external lighting, which strongly suggests an internal thermal or design issue rather than user misuse. At this point, after three identical failures—including two after manufacturer repairs—I can’t consider this model reliable. Optoma has declined further assistance, citing warranty expiration, despite the repeated nature of the defect. This review isn’t about warranty fine print—it’s about long-term reliability. Buyers should be aware that while the image quality is great, the risk of repeated DMD failure appears to be very real with this model.

Since I don’t review projectors daily, my perspective is based on comparing this new 4K projector to my previous Optoma HD146X. I decided to upgrade from the HD146X that was included as an add-on from my home builder. The first noticeable difference was the weight. This new projector is significantly heavier than the Optoma HD146X, which I see as a positive sign of better build quality. The HD146X felt a bit light and flimsy in comparison. Installation was straightforward since I used the same mounting equipment from my previous setup. The standout feature during post-installation was the 4-corner adjustment option. This allows you to move each corner of the screen to achieve a perfect rectangle. Combined with the standard horizontal and vertical keystone adjustments, the 4-corner adjustment made setup incredibly simple. One of the biggest improvements is the noise level. Despite being more powerful, this new projector is much quieter than the Optoma HD146X, which was a pleasant surprise. The picture quality is where this projector truly shines. The 4K image is a significant upgrade, with drastically improved contrast. In a moderately-lit room, the HD146X image was barely visible, but this new projector delivers a clear, high-contrast image even in well-lit conditions, and performs excellently in Eco mode. This projector has exceeded all my expectations. I also tested the 3D mode with my Sony UBP-X800M2 Blu-ray player, which passes through a STR-DH590 Sony A/V receiver, and it worked flawlessly, as expected from a DLP projector. My only complaint is that enabling "Game Mode" removes any geo-image adjustments (like 4-corner or keystone adjustments). This isn't entirely unexpected since Game Mode aims to minimize image processing for faster response times, but it could result in a distorted image if your projector setup requires significant adjustment and if you intend to use this feature. Another potential issue for some users is the limited 1.1x zoom factor, which isn't much. While this can be partially compensated with 4-corner adjustments, it's not ideal since significant adjustments can reduce image resolution. Overall, this projector offers excellent quality for its price. Based on previous interactions, Optoma’s customer service is responsive, which is reassuring. I recommend purchasing extended coverage for peace of mind, especially since my HD146X started showing white dot artifacts after a few years. In summary, this 4K projector has far exceeded my expectations and is a worthy upgrade from the Optoma HD146X.

This is my first projector I am learning a lot about how to set this up and things. I did notice my screen was usually fine but it had a slant in it. I learned I need to take out any slack in the screen from left and right. With the slant going down to the left at the top. I just needed to push that side of the screen just a little and it took that slant away real fast. I got a quick pop up screen first I want to make sure everything was Going to work well first. Now I have a mounted screen it so much easier. Also if you can mount the projector as well cause it's like shooting a rifle at 300 meters. One little hair moved left or right it is going to be off 6 inches when it gets there. So having it mounted where it's not going to move is really needed. But After doing some math was easy where to mount the screen and where to mount the projector. Over all it is great. I do PC gaming and PS5 and Xbox. It's great playing in 4k ultra settings on it. The wife loves movies. We are big Nicholas Sparks fans so watching The Notebook is great. Along with any thing else. Can't beat this for the price and it puts out a great picture.

I bought this mainly as a projector to replace my optoma hd143 which was not bright enough for day time use. This projector exceeded my expectations for day time use. This obviously won't work well enough on a sunny day with blinds open, but closed blinds and brightness turned up this is definitely usable. When it's darker (night time or black out curtains), this projector really shines. The colors are super vibrant and 4k quality is superb. Also, the low latency makes for a fantastic gaming experience.

The overall projector is actually great. It’s much quieter than older models & has a great picture. However, it doesn’t work w/ universal ceiling mounts & whatever chip they’re using for the DLP technology is not good. I bought this projector in April 2024 & already have 3 glaring white dead pixels in my picture. It really screws up dark scenes & from what I’ve read, this requires an RMA w/ Optoma since it doesn’t happen until after the 30 return policy for Amazon & replacing the color wheel &/or bulb will not resolve this issue. I’m really not happy w/ this experience & likely will not invest in Optoma again if they’re cheaping out this bad. If Optoma successfully RMAs my projector w/ working parts, I’d be willing to change this review. Edit: I have 4x dead pixels now. Haven't heard anything back from Optoma, so at this point, I will not be getting another Optoma projector. They're making their products too cheaply & Customer Service hasn't been good either. I'd rather go invest in a company that has at least better Customer Service.

Excellent product I recommend

Overall, this Optoma projector delivers a pretty good picture, but there are a few things worth noting. The image quality is solid and sharp enough for movies and sports, although I do wish it had a sharper image. The remote feels cheap and doesn’t match the quality you expect at this price point. It works, but the buttons feel flimsy. The menus are also not user-friendly, and simple adjustments take more clicks than they should. Navigating between picture modes or settings is more frustrating than it needs to be. It’s a decent projector overall, just not without some design flaws that take away from the experience.

O projetor chegou essa semana, somente consegui instalar no sabado pq não fui trabalhar e percebi um produto bem robusto, com imagens e cores bem vivas e vibrantes a foto que postei é de um clipe em 480p em 4:3 sendo 1.78:1 já o vídeo está em 1080p em 1.39:1 que gera tarjas pretas em cima e embaixo. Mas tive problemas em deixar a imagem exata com o "Trapézio Vertical" pois a peça que tenho fazem anos que é a base onde fica o projetor foi feita torta mas em outros projetores que tive já usava essa peça e não tive tanta dor de cabeça p fazer esse ajuste!

Sadly it din nt work. At 15 feet from the screen i could barely make a 120 inch screen. The 1.1 zoom is not enough ans the focus aint right at that distance if tou want to get it wider. I return it and took the uhd50x, wich have a 1.3 zoom.

Esperaba mucho más ya que ví muchos reviews donde lo recomendaban pero lo tive que devolverl porque proyectaba una mancha verde en un a esquina pero la calidad de imagen queda a deber y la confirmación para intentar calibrar la imagen es es algo complicada

bon prduit

Even a 3500 Lumens projector has a better brightness on the wall , this projector offers 4000 Lumens !
