DL-165 - Unable to display 1680x1050/1920x1080

Hello I am using the adaptor output to a 22" Dell monitor. The naive resolution of this monitor is 1680X1050. There is a 1680X1050 option in my Display panel. Unfortunately, the monitor goes to Energy Saving mode(blank) most of time of the time when I chose 1680X1050 (or anything higher than 1440X900). However, when I was using it yesterday, it shows the naive resolution(1680X1050) without any problem. So, I am wondering if it is a driver problem or the adaptor problem? And I have attached my debug info. Thank you very much.

thank you very much.. i tried to output the adaptor to another monitor(using two different cables). But still only able to display up to 1440x900.. was able to display 1680x1050 only once@@.. so weird.. also i tried the adaptor on Window but still no luck..

This adaptor works with another monitor. This is the third one but there is a ghost image and some flashing.. Hopefully, it is not a hardware problem..:(

yeah, but i bought it overseas. so it is troublesome to return..
