Hi at all!
    This is my first message to this board.
    I have a Vampire 600 v2 128. I'm looking for a compatible monitor for my vampire hdmi output. Today i bought a Philips 246e7qdsw. By trying it I found that I can only display these resolutions correctly:
    1024x768
    960x600
    800x600
    640x480
   
    here there is the monitor specs:
  EXTERNAL LINK   
    maybe the frequency are wrong? there are 30 - 83 kHz (O)/56 - 76 Hz (V).
   
    I can change the monitor at the store but I want to know what I need.
   
    Thanks for help.
    Best reguards.

Did you adjust the pixel clock for each resolution ?
640x480 almost always works out of the box because it's set to 60Hz (Vertical sync)

Most monitors will not take lower frequencies then 60hz.
I had to adjust most resolution to 60hz, and the tune them down as low as my screen would take (lowest was 55hz for my screen (old Asus 22 inch)
Resolutions like 320x200 you can best disable them in P96 prefs by double clicking those.
Then the Vampire will output those on 640x480 automatically.

Hope this helps :)

Is there a tutorial for this? As I am just getting back into the Amiga .. I never even had an RTG back in the day so all of this is new to me.. (I get the general concept .. I am just unsure where you make these adjustments)

Does anyone have a monitor that accepts resolutions without editing?
I would like the simplest solution... :)

I have a Dell 2410 and it runs 800x600 and 1376x768 with no issue and no adjustment.  That is he highest resolution the base install comes with. I still need to create 1920x1200 and 960x600. 

When this ability was first show, I asked if people would post their setting on a thread on here, but no one did it.
