Util for XP to customize res/freq?

[BoB-O TiVo]

Hey all,

I just got a ThinkPad T42 (Radeon Mobile 9600) w/ a 1400x1050 screen. When I dock it, it sends a 1280x1024 signal to my Sony F500R set up for panning my 1400x1050 desktop. Yuk! Since the Sony is an analog monitor, I'm betting it will run 1400x1050 if I send it the right signal, however, WinXP won't let me pick 1400x1050 for the external monitor (I'm betting the monitor config file just doesn't specify it). Is there a utility I can use to force the analog video port to send 1400x1050?

Thanks,
BoB
