Should be able to get 1920x1200. Try using the sticky thread at the top of this Forum, and use the DTD

28 3C 80 A0 70 B0 23 40 30 20 36 00 22 60 21 00 00 1A

If this doesn't work, it's also entirely possible Toshibahas disabled 1920x1200 in the BIOS. To determine if this is true, try 1918x1200:

Aaron Brezenski, you are a lifesaver! any thanks for sympathy!!! Toshibahas disabled 1920x1200 but 1918x1200 works fine!

I know this thread is a little old but I am really hoping I can get some information about this same monitor. I recently purchased the LP2475w and I have it connected via DVI to my Radeon 9800. Every time the monitor is put into sleep mode or anytime the input is switched, the monitor will not wake up from its sleep or not detect that the DVI is still operational. I have already tried several DVI cables, I do have Cats 9.1 installed, I've installed the HP drivers for the monitor, I have reset all the power management settings, and numerous other things without success.

I have read about EDID problems and HDCP problems among some LCD monitors and some ATI cards, can anyone shed some light on this for me?
