Click the link and use the Digital Input at the bottom of the page to select HDMI. When I did it, the selector came up with 24 projectors (8 were under $6k). You will get more hits if you use DVI-HDCP instead (never select DVI without HDCP).

There are some issues with going HDMI to DVI-HDCP, though. Some HDMI devices, when seeing a DVI-HDCP connection downstream, will convert to the incorrect PC level signals (0 - 255, where black is at 1 and white is at 254). You will have to see if the HDMI device you will be using has this issue (HDMI to HDMI does not have this problem). Proper levels for video place black at 16 and white at 235. This allows for below black video signals (1 - 15) and for peak white video signals (236 - 254). That's the correct way and, realizing they've done it wrong for so many years, the computer industry is beginning to move to video based digital levels.
