Default Unable to set 1680x1050 with DVI

I'm trying to set mode 1680x1050 (which is the monitor's native resolution) but the best I can get is 1400x1050.

From Xorg.0.log it seems the monitor is supplying two different sets of information about itself:
(--) NVIDIA(0): AOC AOC203VW (DFP-0): 135.0 MHz maximum pixel clock
...
(--) NVIDIA(0): EDID maximum pixel clock : 150.0 MHz

and later on the monitor thinks the native mode is this:
(--) NVIDIA(0): Detailed Timings:
(--) NVIDIA(0): 1680 x 1050 @ 60 Hz
(--) NVIDIA(0): Pixel Clock : 146.25 MHz
(--) NVIDIA(0): HRes, HSyncStart : 1680, 1960
(--) NVIDIA(0): HSyncEnd, HTotal : 2136, 2240
(--) NVIDIA(0): VRes, VSyncStart : 1050, 1053
(--) NVIDIA(0): VSyncEnd, VTotal : 1059, 1089
(--) NVIDIA(0): H/V Polarity : -/+

But the driver rejects it because the pixel clock is > 135MHz. So I tried a mode line with a resolution 1680x1050 that had a pixel clock of 134MHz but the driver rejected that as too large for the monitor.

Why does the driver think the monitor's characteristics are different to what EDID reports and how can I fix it?
