I both cases I booted with video=nvidia:1600x1200-16@60 on an Iiuama AU4831D 1600x1200 TFT LCD with both dsub and dvi connectors. Using the dsub connector, everything works fine. From dmesg: nvidiafb: nVidia device/chipset 10DE0250 nvidiafb: nVidia Corporation NV25 [GeForce4 Ti 4600] ...can't find one ...found one nvidiafb: CRTC 0appears to have a CRT attached nvidiafb: Using CRT on CRTC 0 nvidiafb: MTRR set to ON Console: switching to colour frame buffer device 200x75 nvidiafb: PCI nVidia NV25 framebuffer (128MB @ 0xE0000000) Using the dvi connector, I get lovely shade of green filling the whole screen. Dmesg is interesting: nvidiafb: nVidia device/chipset 10DE0250 nvidiafb: nVidia Corporation NV25 [GeForce4 Ti 4600] ...can't find one ...can't find one nvidiafb: CRTC 1 is currently programmed for DFP nvidiafb: Using DFP on CRTC 1 Panel size is 1024 x 768 nvidiafb: MTRR set to ON warning: many lost ticks. Your time source seems to be instable or some driver is hogging interupts rip default_idle+0x20/0x30 Console: switching to colour frame buffer device 200x75 nvidiafb: PCI nVidia NV25 framebuffer (128MB @ 0xE0000000) Notice in particular - "some driver hogging interrupts" - "Panel size is 1024x768" (should be 1600x1200) I'll try to boot on dvi without and module parameters and report back shortly. Anything else I can do to help, let me know.
