Hello everyone,

I have my PC at work, which has a video (so it's local)
When I connect it via HDMI to my awesome projector screen, the video is choppy.
Do you know where this could be coming from?
Thanks in advance.

    Hello,

    We need to find out what this video file is... its source, its extension, etc... check with "MediaInfo" and copy the text here..
    Then the brand and model of the projector..

    Is this video choppy on the PC as well..??
    What is the model of this PC..?
    What is its video definition..?

      Hello,
      Actually, it happens with all my videos, on all computers
      For this one:
      Full name: Régionales 2018 jour 1.mp4
      Format: MPEG-4
      Format profile: Base Media / Version 2
      Codec identifier: mp42 (mp42/mp41)
      File size: 191 MB
      Duration: 2 min 38s
      Overall bit rate type: Variable
      Average overall bit rate: 10.1 Mb/s
      Encoding date: UTC 2018-03-16 14:25:11

      You didn't provide the model of the projector...??
      The codec used MP42 and MP41 is from 2005, there are better options now... but who is doing the encoding?? Is it you or not you..?
      I also think that the bitrate is too high. You are at 10 Mb/s which is already quite good... let's say it works on current TVs and PC screens... But your video projector... how many frames per second does it allow?? And what encoding bitrate..? And what refresh rate..?

      I think, I suppose, that your video projector is mirroring your computer screen...?? So you would need to lower the resolution of your image on the computer screen until it becomes smooth on your projector...
      And this image should have a refresh rate of 50 frames per second (or 50Hz)... like the TV.

      There you go, what I suppose, since I don't know the specifications of your projector..
