No it was a doublesight ds-245w (samsung panel)
I didn't think at the time to try other monitors; but I did try different ports (didn't help) for the mice and monitors.
Got a tip for us?

No it was a doublesight ds-245w (samsung panel)

Its no biggie. I was just gonna keep it in there in case I had a problem with the flash. I'll take it out and hopefully all will work again.
Thanks for the info!
Is anyone having an issue with their card (mine is an XFX, getting 2.5GT/s also) where the monitor displays white snow after the system wakes from sleep? I have to manually turn off the monitor and then on in order to get the system desktop again, my main monitor is a Gateway FHD2400, oddly enough my second monitor (1901 from Dell) doesn't seem to have this issue.
Thanks, I only search this thread since it related specifically to 4870 instead of searching the whole forum.
Anyone able to get two DVI monitors working at the same time?
I've read the entire thread and then skimmed through it a second and third time. Lots of reports of works flawlessly or the like but no specific mention of getting 2 DVI monitors to work simultaneously.
Or even better if anyone has been able to use an ACD 30" on the first DVI and then a DVI to HDMI adapter to a 1080p TV without problem.
At least a report of both DVI's working together would be great.
Thanks for the help!

I was looking at the Apple forums on the mouse jump issue...
Another affected user with an Apple OEM 4870 found the problem occured on the DVI port when connected to their selection of samsung and philips monitors. This was particularly interesting as the monitor I was using when I saw the issue was a doublesight display ds-245w which has a samsung panel at its heart.
@ zoppa: what brand monitor were you using???
Anyone else with samsung or philips monitors having problems on the DVI ports? If you have one of these could you do a quick test?
If this is a monitor brand thing then maybe a software fix in the drivers might solve it. This might explain why the issue isn't seen in XP (bootcamp).

excuse me, hi, did you say apple 4870 or the pc version, because i'm going to buy the new graphic card from apple, so i want to know, is the apple ati 4870 card are not working with samsung tv's, because i'm using samsung series 6 32 inch brand, and i want to know if it's going to work with it or not??
before i had a resolution issue because of the cable i was using dvi to vga, then i bought a new cable dvi to hdmi, and it worked using the second cable, is this the same issue you are talking about with the new version ati 4870 or there is another issue??
I'm curious about this as well. Notably, there are more pre-flashed 4870s being sold on eBay now, and they're advertised there as having no analog output (one declared it was coming in 10.5.7...), one dual-link DVI port, and one single link DVI port. I wonder if anybody's bought one, or can shed some additional light on this? Amusingly enough, it seems the people getting into flashing cards don't have lots of multiple/large monitors around with which to test the added horsepower.
jjhny, just wanted to thank you for posting such a concise post. I read all of the material, but a simple "Get THIS EXACT card, use THESE EXACT drivers, and follow THESE EXACT steps" post was exactly what I needed! I just bought the cables and the card from the locations you posted. I have a first generation, 2006 Mac Pro, but from what I'm reading here that won't make a difference.
One question - you say you had both cards in your Mac, then booted into windows, then restarted again. Was there a reason for that?
Well I saw a lot of nontechnical people buying "weirdo" 4850, 4890, cross/back/sideways fire video cards that may not even be close to a reference design - and would certainly be unlikely to work with Apple's EFI ROM, and I felt if I didn't write something quick that this would be the forum of all sorts of cards that didn't work and would be bogged down in endless questions about why such-and-such card doesn't work, and how that isn't fair (I'm speculating, but it sure seemed to be headed that way). After reading through the whole forum, the only card that seemed to be easiest to make work (outside of finding an original ATI reference card) was the Sapphire - and weirdly, the 1 GB seemed to have a better track record than the 512MB.
On the using one card question. Yes, there was a reason, because the system (bootcamp windows XP) seemed to default to the 2600 card for displaying video when both card were installed. When I removed the 2600 card the 4870 displayed video properly. Also I wanted to make sure when flashing the bios with winflash that I wouldn't mistakenly affect the 2600 card. All I can say is that worked out well for me.
Good luck with it. Sapphire 4870 still working great - I'm very happy.

So sorry, but one more question: Do dual monitors (DVI) work with this 1GB card? Or are the 1GB cards still one monitor only?
jjhny and BIEGE,
Thanks so much for the replies. Any 512 MB (or anyone else with a 1 GB) working with both DVIs simultaneously.
Thanks.

1. The mouse jump issue has been reported on OEM-Apple 4870 and non-OEM cards.
2. No true cause has been found yet.
3. Problem may be affecting the DVI port when connected to Samsung, Phillips and possibly NEC MONITORS. No mention of TV connections.
Search this thread for prior discussions of the actual symptoms...
Just wanted to give an update to anyone still underway in flashing the card or looking for information. I'm really grateful for everyones support (Rominator, pipomolo42, netkas, others) for doing this, its amazing the user group out there.
My 4870 was a Sapphire 512mb, the original reference board, one of the very first ones made. I used pipomolo42s ROM and it worked without a hitch. Installed the drivers I found in there following netkas' instructions.
Both DVI ports worked (1x30" and 1x20") just fine! Windows worked after I installed the new ATi drivers for the card.
After 2 days using it I noticed one issue . . . the screen would flash with a snowy/corrupted image for less than a split second. I would only see it if I was working on the computer and looking directly at the screen. This would happen once an hour or so, never was an issue, just the extremely brief flash/flicker of the screen.
Well, I run a business and uptime and warranty/compatibility is very important to me, so needless to say I'm returning my 4870 to the original retailer (2 days left to return it) and installing the Apple 8800GT, as I doubt I'll notice much of a difference.
I don't want to scare people away, this could very well be fixed with new drivers and some time, but like my reasons I just stated, I'll just stick with OEM. After all I did spend close to $3600 on this beast already, whats another $50 difference in GPU.
I'll be curious to see if the new 4870 for the 2008 MPs will be running at the 5gt/s, where the PC cards are not.
Anyone want a Sapphire 4870, pre-flashed including the 2 ATi power cables? PM me.

I have noticed the "snow" on my 512 Meg Diamond.
It usually only happens on second display when coming out of sleep.
The screen comes up and looks just like an old TV on a channel with no signal, then it SNAPS back into correct picture. Lasts no more than 1 second.
I have never seen it happen during regular uptime.
I am forgiving of this. When I wake up, I frequently need a second or two to figure out where I am and what's going on. What a geek I'm becoming... anthropomorphizing video cards....
FYI...I think I have seen mention of this on the Apple boards with the OEM card....may still be a driver bug. We are after all running these cards before the drivers are even in "Stage 1"

Very odd that my "snow" issue always fixes itself instantly and others it does not.
I have a 30" ACD and a 2407 Dell.
What are you running?

What are you running?
Which monitor where you on?
Now that I think of it...I have never seen the issue on the 30" Apple display, just on the Dell.
Be funny if Apple "optimized" drivers to work better on their own monitors.
But they would NEVER try to force you to buy their products through artificial prodding, would they?

If you are referring to type of monitors then I am running a Gateway FHD2400 and a Dell 1901, the snow happens only on the Gateway monitor (no issues with the Dell). Maybe it's the perfect excuse to go out and buy myself that 30" monitor that I have been wanting for a while.
