Ideal for finance, healthcare, restaurant, retail and transportation applications, NEC’s P Series displays deliver UHD resolution, wide color gamut and enhanced functionality
CHICAGO–(BUSINESS WIRE)–#avtweeps Sharp NEC Display Solutions, a global leader in the projector and display market, today announced its upgraded P Series large format displays. The professional display lineup provides a wide color gamut panel, full metal chassis and advanced feature-set for effective and memorable UHD digital signage. These displays are ideal for professional applications in finance, healthcare, restaurant, retail and transportation.
The upgraded P Series displays deliver vivid, crystal clear imagery and messaging with native UHD resolution (3840 x 2160). The displays feature NEC’s proprietary SpectraView Engine, a function that works cohesively with the new wide color gamut, 700 cd/m
I had to remove the following default line from
/boot/config.txt:
dtparam=audio=on
/boot/config.txt, and rebooted:
I confirmed the DAC was working correctly by running
sudo aplay -l.
mplayer (e.g.
mplayer file.mp3).
I should note that by default, using my pair of Audio Technica over-the-ear headphones, I was glad to not have them on my ears when I did this the first time the default volume was something like 88%, and that would ve probably ruptured my eardrums!
I turned the volume down to a more pleasant 4% using the
/ key and was able to enjoy a few songs through the MirkoPC. The audio circuit on it sounds great, and I could not hear any discernible background noise which is better than I can say for many devices!
Great expandability for a wide range of IoT applications
HMI usually refers to the user interface, the dashboard that connects a person to a machine, or a system in industries. Traditionally, HMIs are stand-alone, isolated terminals as a part of a machine that are deployed by Original Equipment Manufacturers (OEMs). As IoT is influencing the way all the connected devices operate with a dramatic increase in the amount of data and vertical connectivity, future HMIs must offer intuitive extensibility for developers to apply AI and machine learning algorithms at the edge that can learn from all the data generated from IoT sensors and adapt to the ongoing behavior of the operator.
