I've asked AMD support many times about this problem and finally get a good answer (FirePro forums are quite dead)
The AMD tech has personnaly added 320x240@60 with AMD Custom Timing Tool with a...

The best way should be to find a guy with a FirePro V5800 or up to test if he's able to add low resolution or not, to know if we can use patched FirePro Drivers with HD5000 +

I'll try to ask on...

I've played with your patched tool and it's the same for me, not able to set low res, it says "Could not add videomode"
I've try some registry keys to see if the tool will allow low res without...

Thanks for this

I'll try that with some registry keys

Kamilz, Can you share your patched tool ???

I just want to test with HD5770 if it has the same problem

Thanks

As expected, i doesn't had an explicit answer from AMD, saying low-res are just not supported by new cards

But they have told me that ALL FirePro have a custom timing feature on XP Vista & Seven,...

You're right, but resolutions below 31khz works if they are in EDID (or used in a edid override )

Another found:
Before i was not able to use Directx10 resolutions, only DirectX9 worked
Now without those annoying drivers, it works!!!

I think i've a big problem with Win7
It's related to RDPDD or "Remote Desktop"
I don't know if it was my source of problem but i've uninstalled ALL the RDPDD driver or services ( those adapters...

As i don't have foun a solution, i've returned to XP X64 and all is working great
Perhaps later i'll try again.....
Thanks

EDIT : You don't have told me : Which version of catalyst are you using...

Well, i've just tried with a fresh install of Win7 X64 and it's the same problem :
I've installed Win7 X64 and then the Catalyst 11.12, reboot and i was unable too choose a lower resolution than...

Thanks for your reply SailorSat
I have a HD4850 wich was working great in XP with soft15khz
I'm using latest catalyst now 11.12

Hello!
I've just upgraded my cab from XP32 to 7X64 and i've seen i'm not able to choose resolutions below 640x480 anymore.
Soft15khz works great with modes 640x480 & 800x600 but i can't use the...
