ATI Radeon 5670 Won't Show Resolutions over 1400x900
- by Phil Sandler
Just got my new Dell computer with Windows 7 and an ATI Radeon 5670. I attached it to my current monitor, which is a Samsung 24" (2443bwt). Windows 7 does not allow me to display in resolutions greater than 1400 x 900.
The setup through a VGA cable into the VGA port of the card. The card also has a DVI port, but I need to use the VGA port because a KVM that supports VGA only.
My old PC (which is Windows XP, GeForce 8600 video) can display in 1900 x 1200 on the same monitor (which is what I want) and even higher. It does this through a vga cable also connected to the KVM (through the DVI port but using an adapter). I have tried the same setup (DVI = VGA adapter) on the new PC and nothing changed.
I have tried:
Updating the drivers via Windows "Update Driver" (says they are current)
Installing the updated version of the drivers from ATI (made no difference)
Installing Powerstrip (all the options I would need for a custom resolution are greyed out)
Installing the drivers/software from ATI caused the ATI Catalyst Control Center software to stop functioning, so I can no longer even start it. I have found some references to other people having this problem and instructions on cleaning the software off and reinstalling it (as uninstalling normally doesn't solve it). I will try this tonight. In any case, I didn't see any options in CCC that would allow me to override the settings for max resolution. However I didn't tinker with it too much before I tried updating the drivers, so I may have missed a setting.
I contacted Samsung via online chat and they say it's a problem with the video card/driver (of course--what else would they say?).
Any thoughts on what else I could try?
