SGI: Video

Hi all,

Can anyone help me to compile video format 1920x1200_50 or 60 for Onyx2 IR2 to use it with Fujitsu-Siemens P26W-5 IPS monitor ( specs - http://ts.fujitsu.com/products/displays ... 5_eco.html ) ? I have tried to do it myself, but with no luck - format loads and screen starts going blank every 2 or 3 seconds. I'v made 1920x1080_59.95 - works great, but would like to use full potential of monitor

Thank you in advance !

I thought on all the Onyx you can use ircombine for set up video.

Yes, thats correct ! I used ircombine to make .cmb but the problem is that video format ( .vof ) wich i made are not working correctly

could you post the source file of the working vof?

i'v used mgras-Blocksync for creating vof files, don't have any sources

ircombine includes a combination file that will load 1920x1200_60 your primary graphics channel <channel 0, the other part of the combination loads 1280x1024_60 into graphics channel 1>. Have you tried using that combination file? You'll need to load a combination file - a single vfo written to one channel won't work. If necessary, you can edit the channel attributes <such as sync> to match those of your monitor .

To make proper use of combination files you'll have to write them to the EEPROM in your graphics engine <the ircombine manual uses the term "download" to indicate the process of writing the combination file to the GE EEPROM>.

Chapter 2 of the InfiniteReality Video Format Combiner User's Guide gives an example of the "download" process: http://techpubs.sgi.com/library/tpl/cgi ... ml#id66871

If you back yourself into a corner with a resolution that won't display on your monitor, you can reload the factory default <1280x1024_60> into the EEPROM using the "-c" switch with the InfiniteReality EEPROM tool: http://www.nekochan.net/wiki/index.php/ ... M_Commands

original 1920x1200_60 does not work - screen goes blank every 2 or 3 seconds. for me it looks like it's loosing signal all the time. i'v played with sync settings - no luck. to load new combination i'm using /usr/gfx/setmon -w either from terminal window or from remote machine via telnet with enviroment variable set to DISPLAY=:0:0. i think monitor does not like 60 hz ! 1920x1080 also didn't work at 60 so i managed to make working 1920x1080_59.95.

I'm probably asking the obvious, but did you download/write the 1920x1200_60. cmb to the EEPROM and then restart gfx or reboot <rather than 1920x1200_60.vfo>? Because IR graphics are muli-channel, they require a combination file - loading a single/uncombined vfo file isn't supported. If you haven't, try I'd suggest doing so with ircombine, rather than setmon. If you're stuck at the command line and find setmon's syntax a little more user friendly, you can write the cmb file to the EEPROM with setmon via the -x or -w command line switches, but I'd still suggest you reinitialize graphics.

The setmon man page gives a brief description of the reasoning for using combination files:
If you'd like to try to build your own vfo file, the readme file located in /usr/gfx/ucode/KONA/dg4/vfo gives specifics of the parameters used to build each of the pre-existing graphics modes. There's a DG4 definition file in /usr/gfx/ucode/vfc/rules/dg4.def for use with the video format compiler that might work better for you than the MGRAS block sync.

If you're working from a command line, ircombine can be run from there as well <see "man ircombine">. I've successfully used the ircombine GUI to load and display that same sample 1920x1200_60.cmb on a <different> 24" LCD.

Although they might not be the optimal resolution, it looks like your monitor does support other display modes. 1600x1200, 1024x768 and even 800x600, but interestingly *not* 1280x1024. You might try a few of those to see if your monitor will accept them <and it would allow you to work in the ircombine GUI>. You could also try the 1920x1200_66 combination file to see if your monitor will accept that.

Other than that, you just might have a monitor that isn't compatible.

yes - i loaded .cmb file not .vfo :

su
/usr/gfx/setemon -w 1920x1200_60
/usr/gfx/stopgfx
/usr/gfx/startgfx

strange, but i don't have such format as 1920x1200_66 ! not in a cmb or vfo. could you please send it to me ?
from monitor specs it says that monitor supports frequency up to 85 hz. if i load combination with resolution lower then 1920x1080 i get a message on monitor - "optimal resolution is 1920x1200 60 hz".

Then it's probably one I made.

bad news - 1920x1200_66.cmb does not work. looks like the only option is to use 1920x1080. anyway - thank you recondas for help !

best regards,

valdis
