BeOS, Win95 and Dual Video Cards

Cliff posted more than 15 years ago | from the could-this-work? dept.

Be 47

Deadric would like some help with the following: "Here is my problem, I'm currently running Win95, and I installed BeOS R4 on my computer. The problem is BeOS doesen't currently like my video card. I just went out and bought another 4 meg card that is supported by BeOS, so I would like to know the following: will windows have a problem with having two different sets of video cards, and each set connected to a different monitor? Will I be able to get software to get dual monitor support in Win95? Will there be conflictions between the two video cards?"Dan has the following hardware setup:

Support for multiple monitors is definitely
planned for a future release. A few months ago
one of the Be engineers asked for suggestions
about features that might be useful/necessary.
Don't know when this will be available. Maybe
R6, but that is just my personal guess.

Windows and MMD (1)

Robert Chin (2357) | more than 15 years ago | (#1991416)

I believe there's a text file somewhere on the windows 98 cd detailing exactly which cards are supported as a secondary monitor. You need to have one of those graphics cards listed in the the text file to be the secondary monitor, though you can select any graphics card to be the primary display.

Note that Windows 95 does NOT support multiple display devices (I believe that Number Nine has written a MMI hack for Windows NT to run multiple of the same display devices), you NEED Windows 98. Also note that if you have a tv input thing on your graphics card, it will not work if it is setup as secondary monitor.

The card which is first detected will be primary monitor. PCI is always detected before AGP, so be careful to account for that if you need to purchase a new card. Otherwise you can simply exchange the physical locations of the graphics cards to change the detection order.

Buy a Mac! (0)

Anonymous Coward | more than 15 years ago | (#1991417)

I've got a 9600 with *4* video cards and *4* 17" monitors.. Mac hardware has supported this since 1984 guys. Steps to install/support multiple monitors on a Mac:

1. Turn off Mac.
2. Open Mac.
3. Put in video card(s).
4. Close Mac (optional).
5. Plug in monitors.
6. Turn on Mac.

There is something to be said for a closed operating system. Believe me, I am a supporter of open source software, I have a Linux box on my desk as well. But man, really tight hardware/software integration makes me feel really cozy on my Mac!

mischa (20337) | more than 15 years ago | (#1991418)

actualy you can have an agp card as your primary.

im running dual monitors with an ATI all-in-wonderpro and a matrox millenium, the millenium has a little dip switch on it that disables the card from loading with the the other pci devices and is not detected until the os starts (as far as i understand it, it was a used card with no manual and the matrox site wasnt very helpful) i believe that switch was labeled pci load or something.

the tv tuner feature ofcourse does not work on the second monitor.

in BeOS i get the loading kernel screen on my ATI card and then im thrown to the matrox

Im new to linux and have no clue as to how to get dual video cards in rh5.2, could someone contact me with help?

Buy OS/2 with XFree86 (1)

Locutus (9039) | about 15 years ago | (#1991419)

Here is one for ya. Put OS/2 Warp v4 on your
system with Elsa cards go get dual display.
Now install XFree86OS2 to either run remote X
clients or local (native OS/2) X clients but
here is the kicker. VNC Server for Linux was
ported to XFree86OS2 and VNC Client to standard
OS/2 (Presentation Manager). See where I'm going?
On OS/2 you have in effect a GNU/Linux system
running with OS/2 and since OS/2 does dual
displays, you can run the VNC client to the X
session on one monitor and the other is the OS/2
desktop where you run OS/2, DOS, Windows16/32s,
Java, TCL/TK, etc. Windows gamers need not apply
cause only a few can be converted to run native
with Win32OS2. I turn heads now running both
OS/2 and XFree86OS2 with enlightenment (and
GNome) simultaineously on my laptop. Dual
monitors in this configuration would have people
looking for the other PC chasis..... :)

No joke. I just compile mico (mico is CORBA)
on OS/2 with minor makefile changes.


NT has supported it for a while, as does 98 (0)

Anonymous Coward | more than 15 years ago | (#1991420)

Windows NT will support up to 4 Video cards (and
I believe Windows 98 will support up to 9, though
I'm not sure on that one). In any case, you must
disable the VGA portion of every video card but
the primary...Matrox Millenniums allow that, via a dip switch, but I'm not too sure that other cards do.

I have had mixed luck with Windows 95 coping with a second video card being in the system. The first time I tried it, I installed both video cards and then installed Windows 95...that worked in such a way that it just ignored the other card. The second time, I installed Windows 95 first and then installed the second video card. This didn't work, as Win95 continually rebooted.

The Matrox Millennium Drivers for NT will see that there are multiple cards and add a button that will allow you to use them both...It treats them as one big monitor...i.e. I am running 3200x1200 (1600x1200 on each one). The driver allows you to select different monitors for each card and different refresh rates, but you are stuck with the maximum resolution of the least capable monitor (i.e. if you had one that could do 1800x1440 and the other 800x600, then the max you could run would be 1600x600 or 800x1200 (vertical orientation)).

Linux handles multiple monitors just fine, but XFREE86 does not have the capabilities yet. MetroX provides the cheapest solution ~$39US. It claims to only work with Matrox cards, but unlike NT, it allows each monitor to run a different resolution. Also unlike NT, the monitors are not treated like one large screen...they are treated as individual displays...as if a different X-Server was started on each one.
Some desktops handle this better than others...Redhat 5.x's default works well. KDE by default just comes up on display 0.0, but may be coerced into bringing another one up if you modify some of the scripts...though don't bother, as the keyboard will only associate with the last monitor you opened an application on (This may have changed, but it didn't work in 1.0 and early in the development they didn't seem all that interested in making it work Multiheaded...I brought it up a number of times, and they were helpful, but it didn't seem to be a priority.)

Deadric (13491) | more than 15 years ago | (#1991424)

Thanks for all the help everyone, i got a S3 virge card, and now I can run Be and Win98 (just upgraded). I would like to suggest to anyone who has a spare monitor around to get a cheap S3 virge, and run dual monitors. Its a big help, and whenever I use another computer, I dearly miss having a spare place to drag my windows. Apparently, both video cards do not have to be both PCI, I have on monitor running off my FireGL 1000 pro (agp) and another monitor running of my 3S virge/Monster 2 card.

The one problem I did have in the begenning is that my primary monitor was running of the S3 virge, which i had set up on my secondary monitor, so each time I opened a window, it would open to my other monitor. I fixed this by having my 3S virge running with my Monster 3d2, instead of my prefered FireGL/Monster 3d2. It runs well for basic 2d programs and still runs great for games.

I was also wondering if anyone knew if BeOS would run with dual monitors? If anyone has any info on that, would be greatly appreciated. Thanks for the help.

I had two video cards isntalled at one time. a Diamond Stealth 3200, and a Diamond Viper 330 (acutally a voodoo card as well - yes it was a diamond too =P ) and there were no conflicts. As for have dual monitor...dunno about that...from what I heard they have to be both the same card... of course I am probably wrong. either way NT wouldn't do it for me.

tonyj (20863) | more than 15 years ago | (#1991426)

I ran 2 17s for a while and I must say its really nice. Now that I have a 21 on my desk, I can say that it really is a toss up. On a coolness scale, of course 2 17s is better, but the trade-off is you've gotta run win98. I couldn't make it work at all for linux. The 21 gives mountains of room, but the added physical room of 2 moniters is a real plus.

What I miss most is the ability to have a browser on the right screen, a development ide on the left screen and executables running all over the place.

IMHO, the 2 17s is better. What I really want now is 2 21s. Once you use two monitors, you can't go back.

Win95 - no , Win98 - yes (0)

Anonymous Coward | more than 15 years ago | (#1991428)

It is possible to get Win95 to run dual video, but it required a lot of hacking around, and it still crashed frequently even when I did get it to work. Win98 does it just fine. I have a generic i740, and a STB Velocity 128, and had to flash my BIOS to get it to select the PCI as the primary video cause the STB has the TV-out.

Gotta check with the card manufacturers though - not every card will run as a secondary, and no card with TV-out (to my knowledge) will run secondary. Also, AGP is always selected as primary on most boards. Like I said, ASUS offered an option in a later revision of the P2B BIOS, but most companies don't.

Unfortunantely, X11R6 doesn't currently support multiple monitors (natively). Supposedly version 4.0 will have multi-headed support (See their web site at http://www.xfree86.org), but until then you'll have to wait. The only other alternative is to purchase the MetroX server, which supports multiple displays on Matrox Millenias ONLY.

You say, "If you have a fairly INTERESTING question (and I'm not talking anything related to FAQ) then I'll hold your question until I can fit it in." What does "until I can fit it in" mean? Are there restrictions on the number of Ask Slashdot posts in a given time frame?

Also, I think it's interesting to note that Clifton is seemingly the sole critique of "INTERESTING". Is anyone else offended by this setup? I'll concede that questions that can be answered by the FAQs shouldn't be addressed by Ask Slashdot, but other questions could be of value to more than just Clifton and the ordeals he is surrounded by.

By way of Datazone's post it seems clear to me that I am not alone in wondering why posts we have submitted to Ask Slashdot have been ignored.

Maybe it's time to open Slashdot a little more. Would it be possible to allow web access to those posts/suggestions that are weeded out?

Disable VGA (1)

red_dragon (1761) | more than 15 years ago | (#1991438)

AFAIK, you'd have to disable VGA compatibility in one of the cards, otherwise you'd have two devices trying to put their BIOS code somewhere in 0xC:8000. Matrox cards have a switch that does exactly that, so that you can install one of those with another video card (or another Matrox card, for multi-head support with only one driver). the video driver won't care about the VGA BIOS, and just use the card directly.

Posted by dhickman:

I got hooked on mutiple heads when I pieced together a Sun 4/330 four years ago. Eventually that system got replaced with a much faster pc running linux and I build another system to run nt. I like running exceed or something simular to access the linux stuff. But I missed the dual head. I did a little research and found out that matrox supported multiple heads under nt. So I bought another 15" monitor and the two video cards. So I have been dual head for a couple of years on a pc.

although I do not care for Winblows 98, it multi heads support is far better than under nt. I like being able to position the monitors anywhere and have different resolutions on them.

If I were you, Buy the 21 and keep the 17, buy two matrox cards and have both.

PCI & AGP--so happy together (0)

Anonymous Coward | more than 15 years ago | (#1991445)

They work just great.

Before I got my TNT, I was using a Diamond Stealth2 S220 card (4M PCI), and an 8M i740 AGP card. Most updated BIOSs have a setting where you can select which video card is detected first, and either one worked fine as the primary. Either card also worked well alongside a 4M S3-virge.

Win98 has good multi-monitor/VC support, and Linux just pays attention to the primary one when you use regular ol' X-servers. Be claims that it will detect and use however many supported video cards you have. If you want to keep Win95, you can go into System Properties, and disable one of the video cards.

You have to go to Win98 to get dual monitor support.

Dual Video Cards in Win98 (0)

Anonymous Coward | more than 15 years ago | (#1991452)

I've got a Matrox Mystique 220 as my primary video card in Win98 and an ATI Xpert as my secondary video card . Having two monitors really kicks ass, I definitely suggest trying it out. I know that the S3 Trio64 is supposed to work well as a secondary video card, and ATIs are a pretty good choice as well. Dual Matroxs are probably yur best bet since AcceleratedX and Metro-X both have multiheaded support. I tried to get the Metro-X that came with full redhat 5.0 to work with both video cards but it didn't work. I heard that XFree86 4.0 will have multiheaded support, I really can't wait for that to be finished, dual monitor support in X will definitely be cool. Its fun to watch peoples eyes get wider as you drag a window from one monitor to the other.

I don't see why windows would have a problem. I think it will use the one that you select in the display settings or whatever. I've heard that windows 98 supports more than one monitor, might want to check that out.

WHACK! went the dead horse (0)

Anonymous Coward | more than 15 years ago | (#1991454)

IMHO, coming from one who owns both - best way to make Windows 95 recognize two PCI video cards is to remove them both and install them in a Macintosh running (insert favorite PC emulator here).

Yeah, yeah, I know I'm beating a dead horse here, but the things the previous authors mentioned, such as independent refresh rates, resolutions, et al, just aren't a consideration on the Mac. OF COURSE you can do it; we've been doing it for about 10 years now. Hell, I can even run one monitor in 16.7 million colors and run the other in 16 color mode. It's interesting to see how windows redraw when they span these two monitors!

Multi-monitors on PCs (1)

Lproven (6030) | more than 15 years ago | (#1991455)

Without wishing to start an argument, some of the
other responses here are, AFAIK, incorrect.

95 and NT do NOT support multiple different cards
or screens. NT can do it but only with Matrox MGA
based cards, nothing else. MetroX also supports a
set of 2-4 Matroxes.

#9 do not support it at all, AFAIK.

BeOS also doesn't, regardless of cards.

Win98 supports almost any combination of cards if
the manufacturer's drivers are compliant. Some of
the common boards can't do this - e.g. Videologic
Apocalypse 3D and 5D.

There's no specific enabling/disabling; the PandP
BIOS does it.

I'm running Linux, NT, 95 and 98 on a two-card PC
here; only 98 can see the 2nd card & screen.

It should work, but one will be your primary VDU,
one the 2ndary, and the 2ndary will only function
under 98. Failing that, buy two Matroxes & a copy
of MetroX.

Correction: Dual Video Cards in Win98 (0)

Anonymous Coward | more than 15 years ago | (#1991456)

Dual Matroxs are probably yur best bet since AcceleratedX and Metro-X both have multiheaded support for combinations of Matrox cards.

Additional multimonitor info (Sorry, NT only) (0)

Anonymous Coward | about 15 years ago | (#1991457)

In addition to Matrox cards, Diamond Viper V-series cards are also capable of running multi-headed NT systems. The standard Viper NT driver will suffice. I'm currently running three 17 sony's on my desk via three V330 8MB cards - though I have to switch to a whole other system for Linux :-(

There are a few caveats, which might also pertain to other OS/card combinations:

1. You can't mix AGP and PCI vipers under NT and get it to work.
2. You can't mix different flavor cards (ie one with TV out, one without, one V330 4MB, one 8MB, etc)
3. Keep all the cards on the same PCI bus -- bridged buses do not make the cards happy. This was a big issue with the Tyan S1836 I originally set this up on - the top three slots are not on the same bus.

Actually two 17" monitors would give 2048x768 (in 1024x768 res) which is 1572864 pixels. 1600x1200 would give you 1920000 pixels. That's 347136 more pixels. All else being equal, go big.
