| 677.4 | 1600*1200 @ 60Hz with TGAII under UNIX ???? | BBPBV1::WALLACE | john wallace @ bbp. +44 860 675093 | Wed Apr 23 1997 19:02 | 14 |
| Re-posted after no answer in topic 9522 in UNIX conf...
I have a prospective customer who would like to run Powerstorm (aka
TGAII aka PBXGB-CA) displays at 1600 by 1200, but at 60Hz not our
standard 65 or 70+ Hz. This is because he is connecting to a high-res
scan converter/frame grabber which is fixed at 60Hz.
The file tga_data.c looks interesting. Can he just put 60Hz as the
refresh rate for one of the 1600x1200 settings and rebuild the kernel
and expect it to work ?
regards
john

| Hello,
according to the PBXGB-AA/CA Owner's Guide EK-PCIGR-OG the frequency can only
be set to 65 or 70Hz refresh, when running in 1600x1200 mode.
60Hz is possible with 1280x1024, 1024x864, 1024x768, 800x600, 640x480.

| 677.6 | Been there, read that. Wish I had a PBXGB. | BBPBV1::WALLACE | john wallace @ bbp. +44 860 675093 | Thu Apr 24 1997 13:38 | 13 |
| Yes, thanks, I should have said I already RTFM.
I'd like to know whether the FM documents all the possibilities. Maybe
it doesn't. If I had a PBXGB-whatever, I'd just try it. But I don't.
Support is not a major issue, this is just to allow ground
demonstrations of something that will (hopefully) be in aircraft at a
later date with a more modern scan converter.
So here's hoping.

| 677.7 | it just might work | WRKSYS::RICHARDSON | | Fri Apr 25 1997 13:12 | 13 |
| More combinations of scan rate and pixel dimensions work in the TGA2
chip than are actually available via the little rotary switch on the
card. The hardware designers that I talked to think that 60 Hz at
1600x1200 probably does (or should) work, but certainly no one has
tried it, so you're on your own (assuming you can get a board to try
this on). You may be in luck.
I would not, myself, want to have to look at a display at that density
that was running at 60 Hz, but maybe in an airplane where there are no
fluorescent lights overhead, it wouldn't be so bad. I find the flicker
at slow refresh rates to be really fatiguing.

| 677.8 | Will give it a go | BBPBV1::WALLACE | john wallace @ bbp. +44 860 675093 | Fri Apr 25 1997 15:31 | 11 |
| Hi Charlotte,
Thanks for the info. I'll have them try it (it may be a while) and
hopefully report back here for the benefit of anyone else who may want
to follow...
Re: flicker. Don't assume that they're using the kind of monitors you
and I get. You know what they say - ass u me etc.
