Without the patch the screen is blurry and the display adaptor does show 2560x1080 is recommended and available. But when you try to select it, the screen is blurry and illegible. So I downloaded the Custom Resolution Utility 1.3.1 and ran it. I then edited it and lowered the max pixel clock to 150 from around 183 where it was defaulted. see screen shots attached.

I still don't understand why you're using the patch if you're using CRU to reduce the pixel clock. Run reset-all.exe and reboot. What happens with just the patch without the CRU modifications? If it's blurry with the patch at 2560x1080 @ 60 Hz, try deleting the extension block and then run restart.exe. If it's still blurry, then the patch isn't working with your GPU, so there's no point in using it. Just change 2560x1080 @ 60 Hz to 50 Hz. You don't need to mess with the range limits. CRU does not include it by default. As for the resolution not sticking, see if deleting the extension block works around the problem.

Brilliant! Ran reset all, rebooted, Deleted the ext block and rebooted again and voila! works perfectly. Not sure exactly what all the patch did or how it worked, but it does and it does work on the ATI Radeon HD 4550!
thanks again for all Toasty!
