ATI Needs to fix the flickering on DP!

[bmac6996]

I just d/l 10.5 and tried it with my setup.. Still have the same issue. It does come up and work when the monitor switches resolution or waking up from sleep.

I have 3 dell 19 inch and a XFX 5770.

[MEAHT]

Anyone tested the 10.5's yet? :)

Downloading and installing 10.5 official now.

I currently use the leaked 10.5 and it fixed the random blinking.
Right now I get expected blinking after quitting games and when coming out of sleep.

[Dyre Straits]

Using 10.5s here. Played a while with Far Cry 2. So far, so good.

[quote]No issues here. I'm using a 5970 with 2 dvi, and 1 mini-dp to dvi (apple) and no issues at all with any version of CCC. For awhile, I had powered my mini-dp to dvi from an ipod usb wall unit. But since, I plugged it directly to one of my motherboards usb 2.0 sockets. Still no issues.

What brand card are you using? And what monitors? Which OS?

I suspect it has also something to do with what brand/type of monitor is used..
Still can't grasp why 10.3 has no blinking while 10.4 has. :(

Sapphire 5970 2G OC Edition, Acer 24" H243H, Win7 64bit Home Premium

I have yet to try 10.5. I'm currently on the 10.4 drivers (non-beta). I've tried just about all the 10 series drivers with no issues with each update.

10.5 official are out? Will install them when i come back from work!!!

This sounds promising:

ATI Overdrive enhancement – full support for multiple displayconfigurations

ATI Overdrive has been enhanced – delivering full support for over-clocking
functionality on supported ATI Radeon™ HD graphics accelerators connected to
multiple display configurations

I guess Eyefinity qualifies for "multiple display configurations"? :wink:

I updated the BIOS from it's original Sept 14th or so to one from November 12th. So far the blinking seems to have dissapeared.

ATIwinflash is a very scary program, if you happen to use it, and your computer freezes whilst flashing the bios, wait for windows to totally crash, otherwise you'll probably bork your card.

Update: right after I installed the 10.5's this morning the monitor flickered twice. I had to go to work so the new CCC was only installed for about 30 seconds before I turned off my system.

[Clayman]

I broke down and ordered the monster DP to VGA adapter from Fry's to test this for myself. I'll report back.

Update:
After nothing but trouble with the accell DP->DVI adapter, I'm happy to report that yesterday I experienced my first flicker-free day of eyefinity. I also played BC2 for over 3 hours straight w/o one issue. Although I can't comment on any other brand of DP-VGA adapters, this monster brand (although a bit costly) is working great.

[Tamlin]

Seems it still flickers with 10.5, so I am stickying this again. :(

Same here, but i discovered something.

When is started with Eyefinity at catalyst 10.1 i bought a passive VGA adapter: lots of blinking and scaling problems (monitor did not scale native but only 640x480). After this i bought an Apple active adapter from one of the forum-members..

This one also had the same blinking and scaling problem even with 10.2 and 10.3. I gave up on the Apple and bought the Accel adapter (newest version with mini-DP). This worked perfectly in 10.2 and 10.3.

But not in 10.4 or 10.4a: blinking all the way (like i posted very often)!! I was very happy when i heard that 10.5 was out and installed right away. But again......................blinking :evil:

Got to think about all that people with their passive adapters and happily using 10.4 (and 10.5) i decided to give the Apple that was lying around a try:
And what do you know..It works... No blink in sight :shock:

Installed the Accel: Blinking.. Apple: no blink. Apple with 10.4: no blink.. i don't get it

So, we should get a different adapter for each driver update then?? :?

Tamlin: are you in the position to try a different adapter?

[spammeister]

The 11.12.2009 BIOS seems to have alleveated much of the blanking.

I'm glad to know you're enjoying trouble-free Eyefinity at last! I, too, have had no issues since switching to the DP -> VGA adapter made by Monster.

[johnnyvd]

Update: The Apple introduced a new problem. Windows not going pas the windows flag screen.
When i restart the PC with the Accel everything starts fine (i have to go into safe mode first and then restart..)

I had to repair windows at one point and it rolled back in a former state. Which happen to be 10.3b.
Reinstalled 10.5 with uninstalling 10.3b but not using driver sweeper this time!!! , With Apple it did not start..
Plugged in the Accel and restarted Safe mode. Restarted again and WTF Accel-10.5-no BLINK??????????

So it works, but i don't have a clue why.



Am i good to go??

**EDIT** after some time the flickering suddenly starts again, unplugging+plugging the DP resolves this..

FOLKS WE HAVE FIGURED IT OUT! CONTRARY TO POPULAR BELIEF Active DP to DVI DOES NOT WORK 100% with EYEFINITY!

After reading a thread last week on the web about eyefinity + HP VGA-> DP adapter working flawlessly I decided to go ahead and order the same item (http://h10010.www1.hp.com/wwpc/us/en/sm/WF06c/A10-51210-64268-1844682-64268-3895841-3895842-3895844.html?jumpid=oc_R1002_USENC-001_HP%20DisplayPort%20To%20VGA%20Adapter&lang=en&cc=us)

IT WORKS! NO MORE FLICKER! Only when switching from eyefinity mode to individual desktops which is expected. I played BC2 for a bit and not 1 single flicker. It even works with the new 10.5 which were giving me constant flickers with the active adapter.

Even sweeter is that the adapter only costs $29.99!

I can go ahead and get a refund for my expensive active DP to DVI adapter from dell.

:rockout :mrgreen: :cheers :D

Can we make this a sticky with the [SOLVED] in the title so that all those people with the same problem (there are plenty) can easily find this page? thanks!

PS
(sorry for the screaming, but this has been a looooooong process!)

Sorry to say, but this is by far the "ultimate solution" we are searching for.

This only works when we are willing to sacrifice the better DVI quality for VGA.
Maybe this is not a problem when you are only gaming, but i also use this monitors for CAD and DTP..

Also you state you still have problems with switching to single desktops.. This should not be a problem.
Don't forget the people that are having problems with native DP monitor!! Is this a solution for them then?

No, ATI and the card manufacturers should look into this, i managed to get a flicker free AND flickering setup with the same drivers and adapter. This is a software problem. Maybe not integral in the driver package but maybe the sequence of installation..

Please keep this thread to NON_SOLVED

[g00seberry]

We already have a thread saying that the DP>VGA adaptors seem to work well here.

You can't say "just don't use it!" to solve the problem. It's not really a solution. People want to be able to use these adaptors without flickering - ATI even say you can use them and they are the "highest award of quality". Hence people are angry and they need to fix it.

Hey johnny,
Im sorry to say but you are mistaken my friend. There is no difference in quality when comparing DVI to VGA using eyefinity.

Games look exactly the same, you use CAD? I use Cinema 3d and I saw 0 difference. Photoshop? nope. Websites? nope. Text
when typing up a paper? not at all.

Ive used DVI, Ive used VGA for over 15 years and the only difference I see is that you can say "I hook up my monitor digitally".

Please dont go and post scientific studies or tests to show us that there is a difference because when it all comes down to it
the only thing that matters is how it applies to our everyday computing, and for me and the posters in that link to that thread posted by EZ which
is now 16 pages long seems to confirm what Ive been saying about DP->VGA adapters, this is the flicker free solution.

And I dont have a problem when switching to single desktop I just wanted it to be clear that there is still the mandatory "flicker" when switching profiles
which is not the same flicker that happens randomly.

I said it was a software problem before as well, but if I use this adapter i can install 13a-15a and it still functions 100%, I cant help but change my mind now because the proof is there. No matter how much success a certain driver brought it still exhibited random flickering to some extent.

ATI's problem comes from the fact that they are recommending that we use Active DP adapters when according to this forum and my findings that is completely false.

Hey Johnny have you tried using a DP->VGA adapter yet? If not then you should.

About the guys having problems with the DP monitor, im still not 100% convinced that the flickering theyre seeing is related to our issues with the adapters.

MEAHT: i think you are missing the point here.. These adapters are certified. So they should work.

And, yes, i just plugged in my DP to VGA adapter (one from the mentioned "working" thread) to check with 10.5, i had this one lying around since 10.1 or somewhat earlier.. And it doesn't work, same blinking as the active ones (apple included)

May I ask exactly which DP->VGA adapter you're using?

While I definitely agree that the recommended/certified adapters should work, the one very highly recommended one [ACCELL] did NOT work for me. The Monster brand DP->VGA adapter is working beautifully, AND, like has been said by several others, I see no discernible difference between DVI/HDMI and VGA image quality.

Same as texasTango http://www.widescreengamingforum.com/forum/viewtopic.php?f=64&t=17468 first post..

But as i said before, this is not the point. I reacted to MEAHT because i think branding the Ative adapters as NOT WORKING isn't completely logical..

I had loads of problems with the Apple and VGA adapter under 10.1 and 10.2. I bought the Accel which was working flawless up until 10.4.. I was really stumped to see the Apple working perfectly under 10.5 again! Only thing is that my PC hangs at the windows flag when i restart it for the second time with the Apple connected.

So, it seems driver version has a lot of impact on the functionality of the adapters. Maybe at the moment the Monster brand VGA adapter works for you, but wil it after the release of 10.6 or 10.7? I would like to find out what causes the blinking and what can be done about it. Be it software or hardware.

This seems to be complex matter and up to now nobody has related the problem of blinking to driver, Bios, GPU Hardware or Adapters!
Just some things work for some people and other things for the rest of them..

It would be great to gather all information together in one database and crosslink bios version, adapter type, adapter revison, OS, GPU harware/revison and brand/type of monitor.. Who's with me?

**EDIT**
And to be complete, my BIOS info:

[spammeister]

I'd say "Update that BIOS Johnnyvd" but....hmmm, that is the most up to date BIOS from techpowerup's database, bummer, as other brands seem to have newer BIOS.
