Eyefinity Bezel Compensation - Fixing bad EDID's

[rebelstar]

But the way pre-release driver 10.3 has out. Installed it... and.. still no bezel management. Looks like I really need to change my EDID :(

P.S. pretty nice changelog :rockout

My Eyefinity Bezel Management now works! Thx!

I did a slightly different way: First I used Phoenix EDID Viewer. Read out the Monitor's EDID info from Registry! Click edit, adjust screen size to your needs, save as .dat. Then go to MonInfo, load the .dat, Create .INF and finally install the .inf driver for your monitor.

I had to log out of windows and delete my Eyefinity config before the CCC would let me setup Bezel Management!

That is some good info :rockout. I never got this method to work with the 10.3 preview drivers. Which driver did you use? The new 10.3a?

Grrr this is still not working on my setup and it's starting to **** me off! Come on ATI, get your act together. We should not have to mess about with flashing EDID data to get bezel compensation working, it's just totally unnecessary.

im running an EDID override on my LP2475w.

But ATI still wont show the Dezel managment :(

Will try and override the Dells to the same as the Hp see if that works

[Phoenixdancer]

nope that didnt work.

Is there a Lower level EDID override that will fix the monitors EDID on my HP?

Its going back to HP tomorrow as it has Dead pixles anyway so what you got!

[shockabuku]

I happen to work for hp and have requested an updated firmware for the monitor, but I'm not holding my breath. I've also had a replacement panel from hp, manufactured in Feb 2010 so bang up to date, and it has the same crap EDID data.

I suspect the ATI drivers look at the actual EDID on the monitor, not the data in the registry, hence why EDID overrides don't tend to work. Dumb programming imho.

[IGNORE THIS]Please see the start post how to unlock the EDID of your HP LP2475w! I have the exact same monitor and have updated it successfully.[/IGNORE THIS]

Never mind this, I was able to flash the DVI port EDID, but not the DisplayPort. I ended up flashing my other 2 monitors... :doh

[Phoenixdancer]

yup i did that, Its unlocked an all but still error when trying to update the EDID

[shockabuku]

Thanks for the info, but I thought you ended up flashing your Samsungs instead because you couldn't flash the DP port on the LP2475w...? I'm in the same boat, and want to keep using DP on my HP monitor.

Let us know if you have any results getting an HP LP 2475w EDID update from your employer :).

[Phoenixdancer]

hmm

im very confused now

According to Moninfo My HP lp2475w is showing 2 EDID in realtime (Onboard EDID?)
One is old 540x350 and second is new 520x320

My Dells seem to think they are 38" Monitors now :O

Something has gone very wrong here lols

How do i delete all these registy EDID's?

[shockabuku]

Just re-update the drivers for your monitors in device manager.

[Phoenixdancer]

Break through!

Plugged in the HP via Display port

540x350

My 2009 2408Wfp in realtime is showing the same

My 2008 2408wfp is playing hard ball and showing the 520x320

(am trying to update this now)

First, REBOOT your system after flashing if you didn't do this already.
If the problem still occurs, I would try to uninstall your monitor drivers. Oh, and remember to check the 'remove driver files' (something like that) when asked.

The location Windows Vista/7 stores the EDID information is in HKEY_LOCAL_MACHINESYSTEMCurrentControlSetEnumDISPLAY[MONITORID][SOMEID]Device Parameters, value "EDID". Modify or delete at your own risk.

Anything special you needed to do to unlock your 2408WFP EDID? If so, I will update the start post with the information.

[Phoenixdancer]

nope.

unsure how i did it in the forst place.

When i try to update the 2008 model it gives me a Blank screen of a solid colour then the PC restarts.

i did this for the 2009 model but that seems to have flashed fine....

Will keep trying

[shockabuku]

This is crazy, ATI really shouldn't be pumping stuff out that encourages people to do potentially damaging things to their monitors. I'm stopping short of re-flashing the EDID on my monitors. If ATI can't point their driver at the EDID overrides in the registry instead of the monitors themselves within a few driver releases then I'll be taking a look at what nvidia can offer.

Since the Dell 2408 has a display port connector (or am I wrong?), maybe it is a good idea to connect the HP via DVI and flash the DVI EDID of the HP?

[Phoenixdancer]

I think i will end up selling my HP LP2475w....

HP replyed to an email i wrote about an EDID update from them and they said:

Hello James,

Thank you for contacting HP e-Solutions.

This email is with reference to the case number: 3683311 for HP LP2475w Flat LCD Monitor.

According to your e-mail, I understand that there is a mismatch in the EDID chip data. Hence, you need an update for the EDID chip to correct that data.

I will surely assist you in providing the required information.

James, since we are from the technical support department we isolate and troubleshoot the issue remotely, however to get a fix for the hardware related issues I suggest that you please contact your nearest HP ASP in your location or contact your country support to get a onsite service for the same.

Please be informed that you have reached the HP North American Support Group. We appreciate your business and we will continue to assist you to troubleshoot this issue on a best effort basis. We at the HP Support Team would provide you assistance for all technical queries.

However, please note that during the process, if this requires a replacement of any specific parts or if the system requires to be picked up for service, then we would also request you to contact the ASP in your location.

I would also like to inform you that all the emails are routed to HP North American Support Group. Hence, I request you to call the HP UK support or you could chat with HP UK support for any replacement.

http://welcome.hp.com/country/uk/en/contact/contact_us.html

Once again, thank you for contacting HP e-Solutions.


So i will be calling UK HP in the morning.

They seem to say its a mismatch so hopefully they can send someone to fix it or give me a guide to fix it.

There is a reason there is an option to unlock EDID writeing so hopefully i can get this sorted.

if i cant then i will be selling it and buying one more dell 2408wfp and useing that.

When you phone the UK team, tell them it's the same issue as I have reported in case #4611341283 (which is still outstanding). It would be good to let them know there's more than one of us (at least!)

By the way, the hp UK support number is 0845 1610030
