I have two of those. Our house has two Xbox Series X, after all. :lol:

The graphics are superb, indeed. You just have to adjust the display settings depending on which game you are playing, though.
To know is essentially the same as to not to know. The only thing that occurs is entropy.

4K Laser TV uses liquid cooling for super-quiet operation

The GAC Technology Group partnered with HP Inc in early 2017 for a 10-year alliance to develop and market smart projectors. The BP5000 is the latest fruit of that collaboration, a Laser TV 4K ultra-short-throw projector that has won't disturb movie watchers with irritating fan noise.

Currently funding on Indiegogo, the HP BP5000 DLP projector uses an ALPD 3.0 fluorescence laser light source for more than 25,000 hours of use, and features liquid cooling to keep the system from running hot, so users should benefit from very quiet operation.
Liquid cooling technology helps keep the system from running hot without the need for irritating fans

New synthesis process paves way for more efficient lasers, LEDs
https://phys.org/news/2021-10-synthesis ... asers.html
by Matt Shipman, North Carolina State University
Researchers from North Carolina State University have developed a new process that makes use of existing industry standard techniques for making III-nitride semiconductor materials, but results in layered materials that will make LEDs and lasers more efficient.

III-nitride semiconductor materials are wide-bandgap semiconductors that are of particular interest in optic and photonic applications because they can be used to create lasers and LEDs that produce light in the visible bandwidth range. And when it comes to large-scale manufacturing, III-nitride semiconductor materials produced using a technique called metal organic chemical vapor deposition (MOCVD).

Semiconductor devices require two materials, a "p-type" and an "n-type." Electrons move from the n-type material to the p-type material. This is made possible by creating a p-type material that has "holes," or spaces that electrons can move into.

A challenge for people who make LEDs and lasers has been that there was a limit on the number of holes that you can make in p-type III-nitride semiconductor materials that are created using MOCVD. But that limit just went up.

"We have developed a process that produces the highest concentration of holes in p-type material in any III-Nitride semiconductor made using MOCVD," says Salah Bedair, co-author of a paper on the work and a distinguished professor of electrical and computer engineering at NC State. "And this is high quality material – very few defects – making it suitable for use in a variety of devices."
