    Thank you for the Information that you not know which Pixels inside the Pixelrange (768x576) are active.

    I have reread from there the difference of the PAL Resolutions comes (768, 720, 704) and the main Problem is the PAR. And this is with the Amiga 1 (Square) and not 1,0667/1,904 (Non Square) which comes from changing from analog to digital in the Video technology (learned something again).

    The main problem was, that I have ignored that the MK3 is a FlickerFixer which will convert the video out of the AMIGA to Signals which modern Monitors will understand and not only a converter AMIGA2HDMI (like the RGB2HDMI Project with the Rasberry where I would be interested to know how they solved the PAR problem).

    720 pixels wide is less than the full overscan of an ECS computer. I am totally with Timm that this is not useful for an Amiga.

    OK, you are right that PAL in DVB Standard has also 768x576 Pixel, which the AMIGA can also use in Oversan mode. But which Resolution most of the Games (or Demos) have? 320x200/320x256. Maybe 640x200/640x256. Overscan was only use an Workbench and here we have with the MK3 the SuperHires Mode. But for Games 576i with a Resolution of 720x576 is (in my humble opinion) is enough. The Benefit is, that such an Resolution will be Zoom from the TV without Black Bars in Top and in Button.


    The Main Problem is that 576p50 will maybe not Work with the TV (in SDTV it was not a standard) and 720x576p25 has a to low Framrate. With 720x576i50 it will work (SDTV Standard) but this Resolution will only Work in the Non Interlaced Amiga Modes without Flicker.


    @xarynorm

    I Think, the Problem is, that the MK3 will give out 50 Full Frames. The HDMI Port will maybe only Accept 50 Interlaced Frames or 25 Full Frames with this Low Resolution. Maybe, you can reduced the HFreq to 15 KHz (Original PAL) but as I wrote above, this such a low Frequence you can only use the Low Resoltions without Flicker (and I don't know if you can reduce the HFreq so much with the MK3 because the Main Function is the remove the Flickr and convert Interlace to Progressive. Maybe it is much easy to use the Standard Scart Cable.

    You are right. there is no controll instance that will check if all of the spcifications of HD ready realy work. I will remember that Phillips has in the beginning very big problems with HDCP, even they have the Logo.

    Also, I am no expert what the EDID descriptor have all for Inforamtion. But Video was alltime a Kind of Hobby from me and I know from my life, there is a differnet beetween what has to do and what done. If the EDID will always work and are correct, why every device which I have used in the last years has a test function to test the resolution? I alwas don't know, if EDID are also used inside consumer electronic or only because HDMI is compatible to DVI.

    Why is the resolution too low?

    This is the Standard PAL resolution. So It makes sense to use this for LowRes and HighRes (Not for LowRes Interlaces and HighRes Interlaced) because the Upscaler in the TV knows this Resolution and can fit it to the native Resolution of the Panel (OK, some TV will stretch it to 16:9 and that looks horrable).

    The only Idea I have, why it will not work is, that the EDID Information maybe wrong. it Means 720x576i50 and you will send 720x576p50.

    Interessting for me is, that if I look in the englisch Wikipedia for EDID, there is NO Preset for 576i fir 720x576@50 (Interlaced). Only for 720x576@50 progressiv. But I know, that I can send interlaced signals over HDMI.

    You are right, But 720p50/720p60/1080i50/1080i60 must working, if your TV has the HDready Logo. Also I think,576i50 and 480i60 must working (but here I am not sure) if the TV has the HD ready Logo, even the panel of the TV has a complitly differnet native resolution.


    Once again. I am speaking of an consumer TV, not of an Monitor with HDMI/DVI Input. And why EDID has to send resolutiosn, which are not used from any computer and every consumer device knows, that they are working?

    But xarynorm write 'his TV' and 720x576@50 Hz is a normal PAL Resolution (576i50 or 576p50).Also 1280x720 is a Standard Resolution in TV (ARD and ZDF will sen in 720p which is 1280x720p50Hz). So If he use HDMI (I know, the MK3 has no official HDMI Port), this Resolutions will be work. But I think, EDID was for Computer (PC) and there, this Resolutions was never used. This is the reason why its missing.

    At the Moment I am Looking Forward to get a 68060 Turbo Board from three sides. At Vampire I am on the PreOrdered List. At Warp 1260 I am Wating for a PreOrder Option (here I Like the Idea with the Passthrou of the FlickrFixer from CSLab thru the TurboCard) and then Individual. Even this will be only a TurboCard without other features this will also be a very nice card, even I know that the kompatibility will be very high. So the Winner will be this company, which want first my money ;)
