Can anyone helpme figure out what's happening?

Probably another limit in the driver. You should get a proper adapter so you don't need to use the patcher. Passive adapters are limited to 165 MHz pixel clock. You need an active adapter, or use HDMI directly if you can. In the meantime, you can use CRU to reduce the refresh rate to 50 Hz to stay under the 165 MHz pixel clock limit.
