Recently I’ve decided to compare ViewSonic PJD7820HD vs Optoma HD141X and straightforward I noticed the simplicity of Optoma HD141X connection to my MHL through a single cable solution. So, I have everything on the wall that I have on my smartphone. Moreover, I can control my device with the remote. It has inexpensive maintenance of the projector and a long lamp. It lasts for 6,000 hours in Eco mode or 5,000 hours at full power. This makes the Optoma HD141X in opposition Optoma HD141X vs ViewSonic PJD7820HD, cheaper to own.
Not all even expensive models work perfectly at a far distance, but this one does; I have put it upside down, 8 feet from our 100-inch retractable Da-Lite 16:9 projection screen and the result was better than I have expected. Brightness is great; it works regardless of natural or artificial light. It doesn’t lose quality even a 10-foot screen.
