Do SGI's support wide screen format? I'm thinking about a wide screen LCD and wondering if it would be supported on either my O2, or Octane.... I'm really considering it for the O2.

Any help would be appreciated.

Thanks :D

Is it possible to go from 1600sw card to a standard monitor either VGA of DVI ? I think I already have the card for the 1600sw but I would prefer to use a 24inch dell flat screen.

miunk wrote: o2 does /w flat panel adapter option + 1600sw monitor. The resolution is 1600x1024. I don't think you can get 16:9 proportions via vga on the o2. You should be able to find the fpa and a 1600sw on ebay for fairly cheap - $200 max, but if you have a good eye you can get them for less.

What's an FPA? Is that something SGI-Specific?

I think, there is also another solution.

There is a way how to get 1600x1024 60 Hz from the DB25 VGA output :-)

Just turn on O2 with the FPA adapter in on and you WILL get also 1600x1024 60 Hz resolution from VGA connector.

I have tried this. :-)

This is (max. 60 Hz of vertical referesh) not good for most CRT monitors ! , because of screen blinking, it is NOT recommended by SGI, but LCD should do fine also with 60 Hz :-) ))))))))

I have an O2 with FPA. Unfortunatelly, I dont have WORKING 1600SW now :-( - I do have one - but It does not work :-( .

Was just trying to load the NFO file but can't manage to find which program loads this file..... hrmmmmmm.

I doubt there is any chance to get 1920x1200 out of an O2. I built a 1680x1050 mode for O2 lately, as somebody requested one in a different thread but i have yet to get any feedback for it. I have no idea if it works as i don't have access to an O2 or a 1680x1050 display:

http://www.kanera.net/modes/crm/1680x1050_60-205bw.nfo

it is based on a similar mode i compiled for VPro before but i had to lower the TotalPixelsPerLine a bit or vfc would refuse to compile it for CRM at all. So if it works at all, its probably pretty close to what you can get out of the O2.

As for Octane, any VPro will happily do 1920x1200. V6 and V10 would have to run it at 8 bytes/pixel though, as it would need ~36 MB framebuffer at 16 bytes/pixel. At 8 bytes/pixel there should be ~10 MB left for textures, actually more than what is left at the usual 1280x1024 at 16 bytes/pixel..

Cheers,

Ah I got it to load the file ! Just needed to rename .nfo to .vfo.

Display works, but when you try to move windows, or click on the toolchest it freaks out.

Looks like you almost got it tho...

Seems like you are talking about the Octane......

Does anyone know if O2 has ever worked on a wide-screen res ?

I'm looking for any resolution that might work with the O2.

Also looking for how the VFO was compiled that I tested previously.... Any details would be extremely helpful. thanks.

I think I may try to embark on compiling my own VFO file. Yikes!

The MXI losing everything at UXGA thing is what made me decide to fix my 1800FP panel and use that in place of a 2001FP until I score a V12 one day.

1600x1024 does not work on Dell 2001FPs. The controller thinks it's being fed 1280x1024 and won't budge from that.

Frankly, though, the 1800FP is a damn good display as it uses an LG S-IPS panel with 8-bit subpixels and no dithering. 18" SXGA is always better for the eyes than 17" SXGA. 19" SXGA is even better.

Anyone had any good/bad experinces with trying to compile custom VFO files for their O2 ?

Looking to embark on getting a wide-screen resolution to be supported for O2 and wondering if anyone has had any similar desires or achievements in the past that they wish to share the experience with.

Thanks for the link I actually have not seen it.

I see they mention MGRAS alot for the SOLID/HIGH/MAXIMPACT cards... Just curious where the O2 fits into all of this.

So does that mean you build a 1600+ res wide screen driver for the V12? I have one of those boxes as well, would love to try to go wide screen on it...

Also always wondered what happens when you plug in a dual head DVI add-on, I expected that you would automatically get enabled for the new resolutions but maybe that's a silly assumption for me....

Ive been curious if it is possible to get a 1600x1050 dell running on a octane V6 or would i be better off to fork out the extra couple of hundred for a 1600x1200 one?

unfortunately, V6 and V8 are a special case thanks to their pixelclock limitation (as discussed in many older threads). There is no chance to use 1680x1050 with those and 1600x1200 will only work if you find a display that will still sync at 70hz or higher on the analog port (60hz will not work) :-( V10 and V12 don't have that problem anymore..

Well that answers my question :) Looks like I'll be using the 1920x1200 when I get my Dell 30" and DCD card... I really just want the DCD for the DVI outputs, I don't plan to run dual monitors as "30 should be more than enough desktop space.....

I can imagine how good the V12 will look at that rez with DVI on "30.

wow extremely useful info to have since I haven't made my company fork out the cash yet for the 30 inch.... Do you know at what size monitors start requiring the dual link DVI ? Could I possibly get away with a 27? or would I have to scale back to a 24"

thanks a million for all helpful the info

Hm, probably not too impressive..

Native resolution of the 30" is 2560x1600 (needs dual link DVI which no SGI provides) - using anything lower will be interpolated and look fuzzy, regardless of whether you are using DVI or analog..

Well to everybody that said it couldn't be done - I have 1920x1200 (WUXGA Wide Screen) up and runnning on my O2 via the standard VGA card (not the 1600sw).

I will post a .vfs source later and if there are any volunteers with a place I can upload it I will be happy to post the compiled video code as well.

Here is the VFS file you can use to compile your own driver.

This is for 1920x1200 for the O2's VGA connector. It will *only* work in 16bpp mode.

Do you know if it's possible to have someone perform the upgrade for you?

I have a 300mhz CPU module, and the 600mhz upgrade chip. I just don't have the hardware skills neccessary to perform the upgrade, and would like to swap an already upgraded board for my existing board + cpu.

Any idea who I might contact for sucn an endeavor?

Thanks in advance.
