Review: Muy buen proyector, a penas voy empezando usarlo, pero va buenísimo me encanta
Review: I am comparing this to having owned an Optoma uhd38, uhd38x, and uhz35. Which are 4,000k lumen bulb and ~3,500k laser, and owning projectors as my main display for about 5 years. I do graphics programming, play video games, and watch TV/movies. Image quality, frame rate, response time, and value are incredibly important to me. Image quality: Color/Brightness: Brightness looks the same as the 4k lumen models I've tried, it works fine in a lit room. Blacks look darker. Colors are more vibrant on default settings, the separate LEDs for color seem to really push. contrast is great. I think this uses a larger dlp chip and that's supposedly why contrast looks better. A lot of the numbers these things claim don't really seem to matter when you compare them in person. 4k60hz mode: looks beautifully crisp, even with keystone adjustment 1080p mode: looks as expected 1440p120hz mode: looks closer to 1080p than 4k, but I am using keystone, so that could be the problem.i don't have 1440p experience, I think 2k also just generally looks closer to 1080p from what I'm reading. Noise: it is louder than the Optoma. The fan is noticeable noise from 4 feet away. You will mostly forget about it pretty quick, but the fan Hum is not a friendly frequency. They should have put like some noctua fans in it for the cost of this thing for less noise Speakers: the built in speakers have surprisingly good bass, but lack the highest range I get from my tweeters in my home theater, which is odd. Volume seems to have good range I only put it up to 2 or 3 for a small room. But I prefer to use my AV receiver for home theater. Remote: feels good. Works, lights up when you pick it up which feels nice. Ui: everytime a new input is detected it asks if I want to switch. every time it detects PS5 it asks if I want to enable game mode. It keeps asking questions and taking up the screen and I have often disabled the keystone by enabling game mode just trying to get rid of the menu. This is annoying, to me. Menus are serviceable otherwise. Boot up time: the splash screen is almost instantly bright, but you don't get control or picture that you actually want for as long as the optoma bulb took to warm up. Built in smart system: not tested. Impressions so far are 4/5 stars. It's better than the Optoma which I loved. It's just that there are some things that could be done better. I'll update over time. Recommended so far.
