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?

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

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.

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

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.

Plugged in the HP via Display port

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?

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.

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
