Hi experts,
I’am a very happy pearl-2 user but with a have a simple question… My hdmi output is always 60hz for some reason. But my footage I shoot is always 50hz ( 1080p50). Why does the pearl not match this and/or can I manually change this to 50hz.
Thanks for all your help!
Ah the Pearl HDMI output uses the monitor’s EDID to select an appropriate refresh rate. So the monitor must be advertising a 60hz capability. Unfortunately there isn’t a setting on the Pearl to set this manually, the only way would be to use something in between the Pearl and the Monitor to have a different EDID. Gefen makes their EDID Detective device for just such purposes which works well: https://www.gefen.com/product/hdmi-detective-plus-EXT-HD-EDIDPN
Hi Adam, tnx for your answer. The thing is I want to loop back to my main mixer that expect 50hz so now Iam using a decimetor to convert back to 50hz… and this is not good for the image quality… A new question where are the extra 10hz coming from? This is also not improving the 50hz footage i expect?
Maybe a good idea to add this function to change this manually?
Ah, if you want a loop out then the best thing to do would be to use an HDMI splitter. Going through the Pearl will be adding some latency and there is a somewhat lossly colorspace conversion taking place. The splitter would avoid both of these.
50hz to 60hz certainly isn’t good for anything production related, this is duplicating frames periodically. I will certainly file this is as a suggested feature request, but I can’t make any promises about if this will be implemented.
ofcours i want to loop back the signal i produce with the pearl ( inc. titles, pip image… etc) . Not the input signal… 
Of course, totally fair. Unfortunately you can’t control the framerate on the Pearl, this would be up to the EDID of the monitor. You could use something like the Gefen EDID Detective in between the Pearl and the Monitor in order to set a custom EDID for the monitor, this EDID could then only list 50hz support which would make the Pearl output 50hz.
Hi! Is it possible that there’s going to be an update in the future that’d let you select your Hz on the HDMI output, or is this a hardware issue? I frequently run into the same problem, and I’d rather not always bring a scaler.

It’s really wierd to output in 60hz if all your sources are perfecty allined at 50hz
