The basic data of the JVC DLA-X7900 / includes 1900 ANSI lumens, a resolution of UHD (4K2K) 3840 x 2160 as well as a contrast of 1300000:1. The manufacturer lists the lamp life at 4500 hours, achieving a lifespan of 6.2 years when used for 2 hours a day. This model is available with either a black or white housing. For precise setup, the device features a lens shift mechanism that allows for optical image shifting. To plan the individual installation location, a look at the Projector Calculator is recommended. Regarding projection size, the value of 1900 ANSI lumens allows for an image width of up to 443 cm in darkened environments. In rooms with ambient light, the image width should be correspondingly reduced to a maximum of 295 cm. For media input, video signals up to 1080P and 4K as well as 3D are supported, meaning standard Blu-ray formats are processed effortlessly. For integration into professional environments, an RJ45 connection is available for network control and remote maintenance. A look at the data sheet confirms a very subtle fan noise for the projector at just 20 decibels. The projector was released in 2017 and is officially no longer distributed by JVC. However, it remains one of the frequently accessed models in our database.

Yeah, does the E-Shift make noise? Yeah, the filter that slides in and out during HDR content also makes a clicking sound. But its not going to give you a heart attack. Or if it did, youd have had one just from swatting a fly.
I?m still happy with my X7900 even after years and 650 hours on the first lamp.
The only issue I have: The optics mechanism is a bit imprecise, which is why I?ve never used the lens memory function. Changing the aspect ratio would always result in a fade-in on the screen.

4K and HDR are completely overrated, the entire lens technology in the device whirrs and buzzes, and if the filter cuts in (clack) and you are heart sick, then that‘s it. For 3700€ it‘s an outrage what you get. Maybe then adjust the gamma drift once a year, no thanks. You‘d be better off with an FHD projector, even a good second-hand one, and you‘ll save a lot of money.
