It will work, but a HDMI to VGA adapter is required. In addition, you will not be able to use it for HDCP content like Netflix, but as a daily use projector not having HDCP isn’t the end of the world if you’re aware of the limitations. Not having HDCP just means one less thing to go wrong for content that doesn’t require it :-). I’ve got an HDCP projector for those times, but I usually use the 1210s because it lacks it.
This adapter is what I use on my Dell 1210s - similar problem to yours; no HDMI. From the inside it just looks like another private label Optoma like my Dell 1210s. I could tell by the lamp and control board. These can be quite picky compared to the rebranded Epsons.
