Radeon 9250,Pegasos2 and AmigaOS4.1 FE problem with 1920x1200.I cannot get such mode with display which supports it (i know specs and MorphOS ,and Mac OS X works fine). i try use with DVI next i look with VGA cable which bet means poorer image quality. Display is DELL U2410. any ideas what do. Display says even no singal.

@Vanhapolle

AmigaOS 4.1 FE comes with limited RadeonHD drivers. You'd have to copy your RadeonHD 1.2 or 2.4 version in order to work it correctly (in SYS:Kickstarts).

Radeon 9250 cards use the atiradeon.chip driver, not RadeonHD. So changing the Radeon HD driver won't do anything in this case.

I fixed this itself there is thing which says i dont remeber exactly but i try put it soon here but related automatic display mode detection now it works. Now i going isntall SKD and soon move few fles form my MorphOS installation.(coding projects,68k native software which exact ones should work with AmigaOS4.1 better than MorphOS3.7,exact i mean these are expections at least one of them is,and i mainly maybe code AOS4.1)

@Vanhapolle

Do any of the lesser modes work? If so then you could try seeing if C:DumpDebugBuffer has anything to say after trying to display the high mode. And is DDC enabled to you know?

@Hypex

Now seems all works (oops all what i tested now i try soon test more).and i can check if DDC enabled at least display
says its enabled DDC/CI place...
ps. btw i must install soon extra software form installation cd,LHA,few 68k programs

@Vanhapolle

Dells have some problems under Morphos (and probably in OS4 too) in low res (640x480). DDC returns wrong timings. If you have similar problems check my monitor setup. http://brain.umcs.lublin.pl/~rzookol/DELL%20U2412M

At least here what i quickly looked fine at least "PAL emulation" version. only problem i miss 320x240 type modes for oldschool feeling games etc... i try in few next days put all important modern,and 68k software (only few ones are stuff what i need about 2 softwares i think) here and my coding projects.(and start modify them for AOS4.1). Needs much energy when i transfer files using memory stick (port is back of computer). i must change harddrive when i change os in current setup fine system becouse very likely i rarely going need MOS. Even i like somethings more but important software maybe works better with AOS4.1 what i understanded.

@Hans

You're right. I read that in a hurry.

You may need to add these modes in mamually in the tooltype monitor icon sitting in DEVS:Monitors. They need to be double scanned as AFAIK the smallest mode is 640x480 and you need to work around it. Like so:

MODE=320x240@60D
MODE=320x256@60D
