Optoma UHD50 4K Ultra High Definition Home Theater Projector

Ca fait seulement 2 mois et demi et j'ai déjà des problèmes avec le projecteurs. 50 % du temps, la moitié de l'image est ne fonctionne pas, parfois a gauche, parfois a droite, UNE VRAIE JOKE...en plus, il n'y a aucun service au Canada. je dois faire affaire avec les USA...service tres mauvais jusqu'à maintenant. Je ne recommande pas l'achat. Avoir su, j'aurais choisi une autre marque et non Optoma.

El proyector que me tocó es defectuoso. Zumba con un tono muy agudo esto a veces desaparecía, el menú no responde en ocasiones y se aparece de repente.Pierde la señal de forma aleatoria sin importar si escoges 4k a 30hz o 60hz así como a resolución 1080 y no regresa hasta que lo reinicias lo cual toma al menos dos minutos para encontrarte con el mismo problema.Algunas veces no prendía e indicaba que necesita cambio de lámpara.Nota: use el cable hdmi incluido así como uno especial de alta velocidad e incluso uno de fibra óptica. Para ver si esto remediaba el problema. En verdad quería que me gustará este proyector y trate de eliminar errores porque se ve hermoso el hdr 4k.Sin embargo encontré en reseñas que algunas de estas unidades tiene problemas por lo que pedí mi reembolso y le daré una oportunidad a benq con el ht2050a. Adiós 4k por ahora.Amazon me regreso el dinero en 10 días. En verdad este proyector se ve hermoso. Si no eres tan desesperado como yo y puedes esperar un mes por si sale mal te lo recomiendo ciegamente.

What can I say, there were several labels on the box indicating that this PJ was once sent to Best Buy, and for whatever reason, sent back to Optoma, then sent to Amazon. The box looked to be properly sealed with security tape from Optoma. The box wasn't damaged, but inside, the two egg crate ends were cracked. The UHD50 is very loosely packaged inside it's box, has lots of room to jostle around.Anyway, about the reason I returned it: The on-screen menus would show a fuzzy, double text with a 4K 60Hz input signal. I have heard that this is a problem with something inside called an actuator. At 4K 24Hz, the menus were very sharp. I thought maybe I could live with this issue if it was the only thing, but...The 2 HDMI inputs: only one is HDCP 2.2 complaint. I need two.The S/PDIF output is only 2 channel audio. I wanted to send a ROKU streaming stick plus audio back to my HT receiver through optical output, but I'd only get 2 channel audio.Also, many times during my trying to like this unit, it would try searching and connecting to the sources I had connected. I tried several full speed, 18Gbps cables, 3 feet, 6 feet, made no difference.I thought I would update the firmware as maybe that would help. Optoma does not easily support firmware updates through USB as some of the other companies do.Summary, did not want to take another chance on the UHD50. I'm going to spend a few more bucks and pick up the Benq HT3550. Longer warranty by 2 years, USB upgradeable.

Pretty disappointed with this one. Despite all the positive reviews, I was left disappointed. I own an Optoma 143x and loved it, so I wanted to stay with optoma and upgrade to one of their 4K projectors.This one came in excellent packaging and I was extremely happy to set it up, but when I did, the picture wasn’t as clear and the focus sweet spot was so small that it couldn’t even compare to my current 143x model.I had to return this product for another. I couldn’t justify paying this amount for something that my 143c would do a better performance.

Works really well with the new Apple TV 4K. Picture quality is really good in a fairly dark room.
