I’m considering the Optoma EH401 projector and would love to hear your thoughts on a few key aspects before making a decision.

First off, how’s the picture quality? I’m looking for something that really delivers on sharpness and detail, especially since it supports 1080p and has 4K HDR input. Has anyone experienced the contrast and colors with HDR content? Does it truly stand out in bright environments with its 4,000 lumens?

Sound quality is another area I’m curious about. Does it have built-in speakers that are decent, or would you recommend investing in a sound system? I’d prefer a setup that doesn’t require too much extra equipment if possible.

Also, how does the compact size affect its performance? Is it powerful enough for larger spaces, or would it struggle in a bigger room? Lastly, are there any potential downsides or drawbacks that I should be aware of before purchasing?

Thanks for your insights!
