PaulMonitor capability with ATI 925020101215 03:44
I currently have an LG LCD monitor at 1680x1050. Can the addition of another MODE= line in the tooltype info (MODE=1920x1080@60) on the monitor device get a 25" HannsG with that resolution going? (i.e., can it really be that easy??)

It could be even more easy if you let OS4.1 set the resolutions automatically... ;-)

@Paul

It can be that easy provided that:
1) Your gfx card can generate that resolution;
2) Your monitor can display that resolution;
3) The Max and Min scan rates in the tooltypes allow that resolution; and
4) You have enough RAM to support a screen with that resolution (including any special effects).

But it's easier to just enable the line "DDCMODE=ALL" in the tooltypes and you will get all the modes that your monitor supports.

That implies disabling the "HSYNCMIN/MAX" and "VSYNCMIN/MAX" lines. That info should be reported by the monitor anyway.

Tony's reply also implies AmigaOS 4.1 Update 1 or newer.

It turns out I already had "DDCMODE=Preferred" along with the specific DPI mode for the old monitor. Now I just have the DDCMODE=ALL set and the new 25" worked on the first try.

Wow!! This is really a lot of screen real estate!

I wasn't too worried about the gfx card supporting 1920x1080. I found a fairly high end 9250. I think it has 512 MB on it, so even under OS4.1 it should be using 256, shouldn't it?

Thanks for the pointers everyone.

I don't *think*so, but I'm not sure. But you should be able to answer that question yourself, using the Workbench title bar configured appropriately in Prefs/Workbench. "%mgt" is the placeholder for total video mem in bytes.

Let us know! :-)

It shows 203 MB free out of 255 MB. This is an amazing display. I might get bigger neck muscles from turning back and forth from right to left to take it all in. :-D

Ah, so OS4 does see the 256 MB. I think it has something to do with how the memory is organized in banks or something.

Anyway, good for you.

Do enjoy the size as much as possible, because it won't take long before you would really like just a little more screen real estate. At least that's my experience both with my 24" 1920×1200 Philips, which was monstrous when I first got it, but now feels only sort of adequate, and with our 42" TV, which felt like the whole wall had turned into a TV at first, but now is "just the TV" :-).

Best regards,

Ahem... sorry...

So far, can AmigaOS 4.1 see 256MB gfx cards? Because of what I've heard since now, even if you plug a 256MB gfx card, AmigaOS 4.1 sees it only 128MB.

Or a Peg2 can see a 256MB gfx card, but SAM can't?
ValiantRe: Monitor capability with ATI 925020101218 03:50  #213
@Phantom

Yes, it can. Both the A1 and Sam see the 256MB on the 9250's I've installed in them.

nbacheRe: Monitor capability with ATI 925020101220 01:05  #335
As I said, it depends on how the memory is organized on the card. With some 256 MB Radeon 9250 cards, all the memory can be seen by OS4, with others only the first 128 MB. I have one of the latter ones.

Best regards,

Niels
