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.

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.

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.

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.

I purchased this projector to replace an older Epson. We tried to watch a movie this last weekend and no matter what setting it was on the colors looked really washed out and dull. After messing with every setting I could I realized that the projector was simply defective. I put my old Epson back in place to get by until my new Epson arrives. This was very disappointing but I had read mixed reviews about Optomo in general so I guess I wasn't surprised. For the brief time it worked correctly the colors looked really good. Playing back the new Flash movie really showed how good it could have been. Too bad a week later it wasn't. Also during my initial setup and testing it was running really hot. You can tell it just isn't a quality product as well just by the packaging. Very basic, no foam padding or anything.

We ended up returning this. It was amazing for sports and most viewing, but when it came to movies, like most these days where there ar dark scenes, it really was terrible. The dim scenes were mostly washed out and not what I would expect from a great 4k projector. We have a completely dark movie theatre in our home so this was not a case of ambient light washing the picture out. I suspect it's just a tradeoff from the great motion and colors in bright scenes.... Which were truly stunning. If we could combine those strengths with a projector that could faithfully render darker scenes we would buy it in a heartbeat.

I have owned an Optoma HD29Darbee for 4 years, which was set up with a 110 inch Silver Ticket screen. The throw distance for the UHD38x is nearly identical so swapping the new projector was simple, no modifications to my ceiling mount. This new projector is much brighter and also noticeably sharper with both 4K and 1080p sources. As long as you understand that the zoom range is very limited and choose your screen size and throw distance based on your room dimensions you should be very happy with it.
