skinda0 Posted October 15, 2018 Posted October 15, 2018 I have a couple of old projectors EPSON EMP-8100/8300/9100 that I am going to be using soon that all have DVI, VGA and component BNC inputs. I am getting a problem with connecting a HDMI source to them. I have tried a DVI to HDMI cable which works fine with a laptop but won't work with playing a DVD or other protected media due to HDCP. I get a blank screen when I connect a DVD player or tuner with this method also. I purchased a HDMI to component converter off of fleabay in the hope to get around the HDCP problem. Again it worked fine with the laptop, but no luck with the DVD player or tuner. Has anyone ran into this problem before and found a solution?
revbobuk Posted October 15, 2018 Posted October 15, 2018 That's the way it's supposed to work - if your display device isn't hdcp compliant, the source device will either play a low-res version (if you are lucky) or more likely display a blank screen. VGA and component have no chance of working, only DVI might, but if the projectors are indeed older, they simply won't have the chips inside to satisfy the HDCP elves, and so the DVD player will blank. If your laptop is playing protected DVDs to the old projectors, then that's a bit of luck, and the best you are likely to achieve.

The way I got the DVD to play was to start it on the laptop screen and then drag it across! If I started the DVD on the projector, I got an error that I had to update the graphics drivers and it was unable to play.With the HDMI to component converter, I would get an image albeit scrambled. I did find that there is a button on the DVD player to adjust the output resolution and each setting provided a different result, but the best I could get was still far from viewable. I'll have a look at the HDMI splitter, or failing that look at changing the source video type! May just be easier to go over to component from the source if I can.
Joe Fernand Posted October 16, 2018 Posted October 16, 2018 Assuming the underlying Pixel count and refresh rate of the Source signal is supported by the RGBHV or YUV Input on the Projector we would install/supply the HDFury HDF2 HDMI>Component converter - https://tmfsolutions.co.uk/product/fury2/ Joe
ninjadingle Posted October 17, 2018 Posted October 17, 2018 You mention dragging the video across on the laptop - guess you're running it in Extended mode? What does it do in Duplicate?
Shez Posted October 17, 2018 Posted October 17, 2018 I have tried a DVI to HDMI cable which works fine with a laptop but won't work with playing a DVD or other protected media due to HDCP. I get a blank screen when I connect a DVD player or tuner with this method also. I might be misinformed here but HDCP only applies to high def media - hence the HD in the name. A DVD player shouldn't know anything about HDCP and certainly shouldn't implement it. I think there's something totally different going on here. I'm not convinced a DVI input that's expecting computer resolutions will work when fed from a DVD player - there's a degree of compatibility there but I think a DVD source is really stretching it. If you can find an older DVD player with component out (Fleabay is probably awash with them) that'll probably be your most simple solution. There's no reason why a laptop shouldn't work - some older ones struggled to play video on the extended desktop out as the graphics cards didn't have the oomph to run two desktops with complex processing (video) on the second.
Joe Fernand Posted October 17, 2018 Posted October 17, 2018 HDCP (High-bandwidth Digital Content Protection) is relevant for any device which carries an HDMI Input or Output socket - the Encryption/Key exchange is flagged by a stream within the content and the connected devices then enable content protection - Computers often ignore the Flags, though not always. https://www.digital-cp.com Joe
