I have another question as well. Does using dual link DVI cables for this montiro helps?

What timing parameters have you tried? Did you try the "LCD reduced" timing option?

A dual-link DVI cable won't make a difference. The U2311H is a single-link DVI monitor.

I am currently trying with LCD reduced timing options at 75Hz. The automated values are as below

Front porch 24,3
Sync width 32, 5
Back porch 40, 5
Total 2016, 1093
Polarity +, +
Refresh rate 75.001Hz

I wasn't able to set the resolution in NVCP. But I can set it from windows screen resolution. Testing now for a few days to see if it stays that way. EDIT: The above did not work as well. Black screen at start up this morning.

Below are the other 2 settings that I have tried and didn't work (passed test but black screen during restarts)
Front porch 25,3
Sync width 35, 4
Total 2025, 1092
Polarity +, +
Refresh rate 75.000Hz

Front porch 25,3
Sync width 35, 4

Refresh rate 74.616Hz

Front porch 20,3

Polarity +, -

I can understand that it doesn't work when 165MHz of pixel clock is exceeded. The last 2 are within the limit, but doesn't work as well, not sure why.
