Can't set resolution higher than 1024 x 768 with RC driver

Martin · 10-19-2009, 11:38 PM

I've had a chat with our resident edid guru, and the news is not good. There was a winge that the projector was old, but otherwise the edid looked fine. It is likely that the reason it works when directly attached is that the graphics vendor has added in this mode even though the edid doesn't expressly say it is supported. We do a similar thing in some circumstances, but evidently not in this case.

We used to have a method of adding in additional modes for the display manually, but this is currently broken, so a bug has been raised.

Sadly, there is nothing I can do about the issue now. Look out for maintenence releases, and check back with us on the forum for updates.

Best regards,
Martin

Bummer. Is there nothing to be done by using any utilities out there. Can someone edit an edid file? Manually correct the issue external to your software?

Thanks for following up.

Hi Ross,

I am not aware of a utility to do what you require. I have, however, fixed the problem that prevents us from adding additional modes to the registry. The fix will be in 5.2M1, due in the near future (I guess 4-8 weeks, but no promises).

I'll post the registry key once I've worked out what it should be for your device.

Martin.

That would be great. Thanks!

Hi Ross,

Our latest driver is now available which will allow you to force a resolution to be available, even if it is not explicitly mentioned by the monitor.

Could you please try the latest version of the software (from www.displaylink.com) and if you need the registry modification, I'll work out how to get it to you.

Best regards,
Martin.

Having the exact same issue but running 5.3

I'm attaching the debug info..

Where are those instructions to force the resolution?
