r9 290 - problem via hdmi with non hdtv display

[ariel-ro]

Hello,
I bought a new graphic card - ATI R9 290
There is 4 displays that connecting to it.
The monitor with the problem is- proview 22' - native res- 1680*1050 - the only way to connect to this monitor it's via HDMI. and this monitor work perfectly with 9600GT and ati 5450.
The problem is that when I change the resolution to 1680*1050 the picture is blurry and out of the limits of the monitor. also, the monitor write that it's get a 1080p resolution.
When i try to change the resolution to something that isn't 1080p, 720p and max native, the monitor can't display it.
Anyone knows what could I do?

Thanks alot,
Ariel

Hi,
I tried with configuration of adapters and cables(HDMI-HDMI, DVI-DVI-HDMI and etc) and nothing help.
Also with the hd5450 I had the same problem with a HDMI-HDMI connection, but with with DVI-HDMI adapter and then HDMI cable everything work great.
