Optoma UHZ45 4K UHD Laser Home Theater and Gaming Projector | 3,800 Lumens for Lights-On Viewing | 240Hz Refresh Rate and Ultra-Low 4ms Response Time, White

I previously owned an Optoma HD20. I got 10 years out of it before it pooped out. I use my projector as my everyday TV. So it gets used alot. Was wanting to get into the laser 4k market so that I wouldn't have to mess with replacing lamps. I zeroed in on the Optoma UHZ66. I read all of the reviews and was very skeptical because there really weren't many postitive reviews. So I took a chance. Got it for $1499. It had been listing at $1999. All I have to say it wow. The picture is amazing. My home theater is in my basement so there is no external lighting. I had to set the source light to 80% because it was so bright. I can't believe how crystal clear the image is. Setup was a breeze. Used the same ceiling mount. Not many channels are 4K but I watched the NFL playoffs and OMG. 4K is the real deal. The picture clarity is astounding. Watched Top Gun Maverick and it just popped. Amazing detail. Another positive is that when I changed it to 80% light source, the projector makes almost no discernable noise. Just a light hum. Seems like half of the fan noise that my HD20 produced. Focus is easy with the adjustable dial. Also the throw distance can be adjusted with the 2nd dial as well. Remote is super small which is kind of funny but it works. I've set up my system so that my 4k Firestick turns everything on and off and controlls the volume. Below are two pictures I took. First one is in HD and 2nd is 4k. Just unbelievable how clear it is. It's like being at the game. So if you are on the fence then jump off and buy the UHZ66. You won't be disappointed.

I am very frustrated. This projector had dead pixels due to the faulty DMD chip in the very first month so I was able to return it to Amazon (thank goodness) and they exchanged it. That was unit #1.Unit #2 - this one had the same failure right after the 1-year warranty ended. I will never understand why a several thousand dollar unit would only have a 1-year warranty. It should be at least 2 years but more like 5 years seems appropriate when you spend this kind of money.Try #3 - Now even after having the DMD chip replaced, I am AGAIN, getting dead pixels before we are even at 90 days.This unit is obviously a lemon to have the same issue happen so many times in a row and in such short time frames. I keep my home immaculately clean and I air the projector out once a month like clockwork. I also have the unit set with my AV receiver to auto-turn off whenever there is no activity for 20 minutes. The unit is in open air and well-ventilated so I don't understand what the cause is except for an inherently defective DMD chip.I honestly don't think there is anything more I could do to baby this unit barring putting a custom cooling unit on it, which I shouldn't have to do.I would really like to see Optoma get me into a unit that is equal to or better than the UHZ50. I feel that I have been through enough with this unit. Every time it goes out, my family has no home entertainment for several weeks which is unacceptable. Not to mention the hassle of uninstalling the unit from the ceiling and having to reinstall, adjust, and recalibrate every time.When I think Optoma it makes my stomach sick, which is not the feeling that I should have with your brand. I would like to know that you have admitted this unit has inherent defects and take care of me.This is my 5th Optoma Projector and I have been happy with all the other models I have had. This leaves a bad taste in my mouth and I sincerely hope you can take care of me.

Is it perfect - no, but as an upgrade to my 13 year old panasonic ae4000 1080p its a helluva deal. I was very lucky to have a perfect throw distance in my media room (14 feet), as you have VERY little adjustment with this projector. If you can make it work in your space, its a great projector. Much brighter and sharper than my old one, and it has no bulbs to replace. 4k HDR at 60 hz is amazing. The contrast is excellent, and it is super sharp. I went with the 45 as there is no reason to have "smart" features on a projector (my avr and fire stick already have wifi). Its also about half the size of my old one, and I paid half the price (a quarter the cost when you consider inflation). Great upgrade!
