I have a Pegasos II which multi-boots MorphOS 1.4.5, Ubuntu 7.1, Mac OS and AmigaOS 4.1. I recently purchased a Samsung SunchMaster T260 widescreen monitor and am having trouble setting it up to display its default 1920x1200 screenmode under MorphOS. I have no problem setting it up under the other 3 Operating systems.

I used ModeEdit to set the System systems for my monitor

Horizontal 30 - 81 kHz
Vertical 56-75 Hz
Optimum & Maximum resolution 1920x1200 @ 60Hz

The max Pixel clock is 164MHz for the monitor but I cant find the bandwidth information. I can get a 1600x1200 screenmode which fills the monitor screen, but am unable to get a 1920x1200 display under MorphOS.

Any help gratefully accepted.

MorphOS 2.x could probably find a usable mode for you, should be possible to transfer the settings to 1.4.5 I guess.

Back in the days I used a 1600x1200 mode (75Hz), and fiddled with the settings till I got 1920x1200 at around 60Hz.

It's hit or miss and it didn't work for anybody.

It might also be good idea to connect both VGA and DVI to the monito as DVI might get out of sync soone than VGA 8atleast that was the case with my SyncMaster 245b.

Hi all,

It seems that there is something strange around the Monitor-settings in relation with the graphic cards
from MorphOS 2.0 onwards because I'm also experiencing strange behavour, e. g. I can't connect my
Eizo CG21 via DVI with 1600x1200 to a Radeaon 9250 with 256 MB RAM.

Hi there.

If you run MorphOS 1.4.5 you should know that you have to use DVI
for widescreen modes. MorphOS 1.4.5 is struggling with widescreen modes if you use VGA.

Try that :)

That is incorrect info. I run 1.4.5 (and earlier versions) through VGA on my radeon 9200 to my Dell 20' in full widescreen. I think I used a crt setting in the monitor config and tweaked that... I fcked up my 1.4 install by accidently installing 2.2 over it or I would check... I guess I could still read the monitor config if there is interest though...

For your info. I can say that I have an 22" Dell which didnt work in widescreen vga mode. I had to change to DVI and it worked. I used several hours to try to adjust, but it didnt work with vga. I have ATI Radeon 9250SE. So might be in difference there.

i use a 26" wide screen with 1920x1200 with dual boot 2.2 and 1.4.5, and it work with both, only under 1.4.5 i had to setup everything by hand, what wasn't that big issue. it's connected via vga port (through a keyboard/mouse/vga switch) and it works fine. it's really only a matter of settings... 1920x1200x60 should work with cca 140 MHz bandwidth... don't forget to press the 'autoadjust' button on your lcd, if it doesn't display exact pixels...

bye, MarK.

ps: it also works with old radeon 7000 with 32 megs...
