Default Re: Unable to set 1680x1050 with DVI

As you've already noted, your graphics card has a 135Mhz max pixelclock, and is only single link TMDS capable:

(--) NVIDIA(0): AOC AOC203VW (DFP-0): 135.0 MHz maximum pixel clock
(--) NVIDIA(0): AOC AOC203VW (DFP-0): Internal Single Link TMDS

The EDID in your display indicates the following:
(--) 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 : -/+

You could try the following option to deal with the "Mode "1680x1050_60.00_rb" is too large" error:
Option "ModeValidation" "NoDFPNativeResolutionCheck"

however, I think the bottom line here is that your hardware isn't going to be able to natively do 1680x1050.

Thanks,
