Monoprice DVI-D Dual Link M1-D(P&D) Male to HDMI Female Adapter - Gold Plated, Black

Well made, works perfectly on my Epson (InFocus) X2 projector. But you need to understand a few things.before using one of these.First, no connector will provide HDCP; that's communication between the devices being connected. Most projectors old enough to need this connector are also too old to deal with HDCP.Second, no connector will allow resolutions that the devices can't handle; again between the devices being connected. My X2 supports 1080i but not 1080p. Interestingly, when I connected my BD player (Samsung BD-F5700) and forced the resolution to 1080i, it doesn't seem to care about HDCP and plays both BD and DVD discs just great at 1080i. Awesome! When I connected this to my PC output via an HDMI port on an NVidia GTX750ti, it looked just great as well!Finally, understand that while HDMI supports audio as well as video, DVI never did, and the M1 connector is a DVI connection expanded to support a USB connection as well. So you need to handle audio directly at the source, as it will not make it into the projector through the M1 connector. Having said all that, I'm very grateful that someone makes these adapters and cables for the older tech and at such a reasonable price. Well done!

It is to the eternal frustration of consumers that electronic manufacturers cannot standardize their interconnection standards for components. This is one example.Dell and InFocus video projectors of a certain vintage use a modified DVI connector called "M1" that is not interchangeable with standard DVI cables. Evidently the reason for the modification was to add a USB connection through the same connector. But for those, like me, who simply need to connect a Blu-Ray player (which has an HDMI output) to a projector using the M1 connector for hi-def, this adaptor is one piece of a two-piece puzzle (the other piece being and HDMI-to-HDMI cable of the appropriate length).One thing I discovered is that the Blu-Ray player (a Sony model) did not receive any kind of auto-sensing information about the projector from the HDMI cable through this adaptor. Probably the auto-sensing standard had not yet been developed when the projector was manufactured. So it was necessary to go into the settings on the Blu-Ray player to manually select 1080i (the highest standard this particular projected would handle) in order to get a usable picture. But once that adjustment was made, everything has run just fine.

This was a rarity as I didn't think I would find an adapter like this. I just purchased an older Hitachi projector and didn't realize that there was yet another digital connector type out there. I had never heard of M1-D but I didn't want to run a crappy analog 35-foot VGA cable and I certainly wasn't going to run a full set of RGBHV cables ($$$) so I ended up running an HDMI cable from my computer via a DVI-HDMI adapter to the HDMI cable to this thing, HDMI-M1-D and it works like a charm. All digital signal the whole way with no loss in resolution, it's pixel perfect. People mention that older InFocus projectors used this connector, but the Hitachi ones did also, I can say that this worked, even when I was near certain it wouldn't.

this did not work for me. I have an older INFOCUS LP340b with an M1-DA computer cable. Monoprice people were quick to explain that theirs is M1-D but not DA. A friend finally pointed out that there are TWO ends to the cable. So I got an HDMI to VGA male to female adapter (Cable Matters 113046) The INFOCUS cable is connected to the projector then at the other end I attached the adapter to go from VGA to HDMI and it works great!!!

This product does what it's supposed to and is in use with my older InFocus IN34 projector. This adapter is the bridge between today's HDMI and my obsolete projector's obscure M1 connector. Note that I've seen the projector's connector referred to variously as: M1, M1-D, DVI-M1, and who knows what else... and therein lies my point - I think the confusion this generates plus the fact that M1 physically looks extremely close to an older Mac video connector (M1 has a 3 more pins - and you can't tell them apart unless you count the pins!) is what contributes to the confusion in terms of what this adapter can and cannot do.First, make sure you need an M1 connector. Count the pins on the device you want to connect and make sure they match this item.Second, even if the pins physically match, do you need HDCP? What the heck is that? Yes, that's exactly what I said too! Unless you're familiar with video standards, you won't know what that is either but the take home is this: I could not get my ROKU working with my projector with this adapter. It's not the adapter's fault - it's because my projector is not HDCP compliant. To the best of my limited understanding, HDCP is a "handshake" that needs to occur between my ROKU media player and my projector that says "hey, I'm a projector or a TV screen and not a recording device." This is to prevent the unauthorized copying of movies. Because my old projector does not do this, my ROKU won't play.Note that this adapter works fine with my projector and my WD Live media player. BUT my WD player does not offer things such as Netflix. My uneducated guess is that because of this, my WD player does not require a successful HDCP handshake to begin playback.Lastly, note that this adapter only handles video. Hopefully your playback device simultaneously outputs HDMI video AND also audio through a separate connector. If your device only can output audio and video through its HDMI connector, you will need to find a workaround - sorry I cannot help with this.In summary: this product does what its vendor promised. Unfortunately, I cannot use it for my original purpose of connecting my ROKU to my projector - but it works fine for my other player and this enables wonderful movie nights in the backyard!Hope this helps! :o)~james
