no and I really dont want to do that. I have so much music software and mixing creating stuff installed for my music hobby. It would really be a major endeavor for me to do a fresh install and honestly for the reason we are discussing.. I shouldnt f'ing have to. If 10.6 still blinks I will try the apple adapter.. the thing is I have heard alot of bad things about the apple adapter but maybe it was just because it was shortly after the eyefintiy thing hit the market.

You are right, you shouldn't have to.. That is why i'm trying to find out what is causing this problems.
I will try to do a clean install myself just to see if this problem isn't caused by some "artifacts" from the older driver packages.

Concerning the Apple adapter: i had big problems with it also when i started using it (10.1).. Losing resolution, blinking, etc. But since 10.4 it is working fine!

Im sorry if Im coming off as a pain but I really want to help you guys.

Again I will stress, GET THIS ADAPTER:

Its not the same type that you guys have purchased before. The problem we are all facing comes from having to use the USB ports, once you eliminate the use of USB power everything works perfectly. Like I mentioned in the opening post, BIOS updates will not work. Ive done it all!




Im telling you I havent had a SINGLE flicker. NOT ONE!
Please! Please! give this adapter a shot.

Thanks MEAHT, (i really mean it), just one thing i want to throw in: how about people with 30" monitors?
Don't these resolutions exceed the 1900x1080 res-max of the VGA adapter?

@ the moment i didn't have a single flicker with my Apple adapter :cheers

**EDIT** Guess maximum is 1920x1200:

Technical Specifications
Connectors DisplayPort and VGA connector
Adapter length 8 in (20 cm)
Adapter weight 0.1 lbs (0.06 kg)
Option kit contents HP DisplayPort to VGA Adapter, documentation
Maximum vertical refresh rate 85 Hz
Display support 162 MHz RAMDAC
Display max resolution 1600x1200

NOTE: 60-R denotes reduced blanking timings are used. Not all monitors support reduced blanking timing.

WTF; just did some searching after reading "reduced blanking timing" in the HP spec..

Solutions: use reduced blanking
Reducing the DVI pixel clock makes it much easier to transmit the digital image through the cable. If you have a corrupted image then using reduced blanking reduces the pixel clock without reducing the screen resolution or refresh rate. LCD monitors usually support reduced blanking for modes which require pixel clocks anywhere close to the 165 MHz limit. There's really no point in not using reduced blanking all the time. Display drivers are usually pretty good about selecting reduced blanking automatically when it makes sense. If you're having a digital image quality problem then you can force reduced blanking to be sure. This page explains how to do that.

"Display drivers are usually pretty good about selecting reduced blanking automatically when it makes sense" anyone got a clue what this means? Can Catalyst have a say in this reduced blanking? (source: http://www.playtool.com/pages/dvitrouble/dvitrouble.html#reducedblanking)

Greetings,

New forum member here. I signed up primarly to enter the discussion involving these faulty eyefinity setups.
I'm running an i7-975 on an Asus P6T6 board with a Saphire Radeon 5800 series vid card (bios version 012.011.000.006 from 9/14/2009 and catalyst version 10.2).
Using (3) Asus VW246 with an Accel Dp to DVI adptor (part#B0878-002B) to complete the eyefinity setup.

I'm just another user who is suffering through the same blinking problem on the DP-DVI converted monitor. I get random blinking episodes throughout the day, id say on an average of 1 every 2.5 hours with the actual frequency of the episodes being completely random. Like everyone else, the problem is settled when the DP connector is removed from the back of the card and re-inserted.

A couple questions that I havent been able to figure out based on multiple forum readings...

Are the results worth upgrading the Sept 09 vid card bios to the updated current bios that supposedly resolves the blinking issue for some?

Is it worth it to ditch this $100 Accel adaptor :( for the Apple adaptor that seems to be having more success?

Its just funny becaues when I put together the parts for eyefinity.. everyone told me to stay away from Apple adapter because its rubbish with eyefinity. Now apparently thats the only one that works. I made the mistake of buying the Dell, Accel Adapter. with catalyst 10.4 + the blinking becomes unbearable when I switch resolutions. As soon as the power momentarily cuts out or switches resolutions, I get about 15 to 20 blinks per minute.

I have no flicker with using the Saphire Active Displayport adapter that sells at the Egg. I'm using the Catalyst 10.6 drivers. My center monitor is a Sony Trinitron FW-900 24" CRT, and the side monitors are V7 22" LCDs. All running 1680x1050 resolution with a display group res of 5040x1050 or when using bezel compensation its 5156x1050. I have one of the LCDs on the displayport to vga adapter, the other monitors are hooked to the dvi ports with vga adapters. I have no flicker problems. The LCDs run at 60hz and the CRT runs at 85hz, even in the eyefinity display group.

I could not run resolutions higher than 1280x1024 with my CRT if it was hooked up with the DisplayPort adapter. I'm not sure why this is, but my LCD runs fine at its native res of 1680x1050, so i keep it hooked up this way.

I edited my EDID on my FW-900 to match the physical screen size of my LCDs so that i could enable the Bezel compensation. (22.5" viewable on the CRT as apposed to the 22" on the LCDs). This worked great though.

Is it maybe just the DisplayPort to DVI adapters that are having blinking issues? Could hooking the monitor up through the VGA port on the monitor instead if available and then using a vga to dvi adapter on the displayport adapter possibly fix the problem?

So far, it seems that the error is related to which adapter you use and that some driver sets makes the issue less.

Sapphire's active DP -> DVI adapter and HP's DP->VGA adapter seems like the best options. I hope ATI reads this and checks to see what differed in the drivers, so they can do something about those who has adapter issues. :)

To note, i used the Saphire Active DisplayPort to VGA adapter, not DVI.

I didn't know they made one. :) Thats good!

Yeah I just purchased this at the egg... came to 30 bucks though.. add that on top of the 100+shipping and tax for active display port dvi adapter... now I am pushing 150 bucks on a stupid adapter. All I gotta say is that when this comes in on monday, it best be workin.

I am also worried that using analog is going to look blurry.
