A certain design company has purchased our company's 98 inch wall mounted teaching and conference all-in-one machine, which is installed remotely under our technical guidance. It has been in use for some time now, and the customer feedback is that the use is very smooth, with realistic colors. It can not only be used to train employees, but also for project meetings and design. Thank you very much for the support and trust of the boss of the design company.
