I had to replace an 4:3 Westinghouse monitor this weekend. I got a new ASUS VH242H, which is very wide. But Xorg is still running 1280x1024, instead of the monitor's normal 1920x1080, according to xorg logs because of lack of video memory (using the ATI on the motherboard). I can make the screen use a 4:3 aspect ratio, so I'm up and running, much better than I started, but I'd like to do better.

I guess I've gotta look for a video card, but all I have is PCIX slots, so I don't want to put a lot of money into it (I'll be upgrading the mobo when finances permit -- which is not right now.)

Any ideas?

Have you tried setting different modelines etc using cvt and xrandr?

No. I ditched my xorg.conf completely; it had been there just because I couldn't get the Westinghouse monitor to work without it. The Xorg logs show it recognizes a boatload of
modes that the monitor likes, but gives an alibi for not using the HD ones. The approach
does not seem promising.

/var/log/Xorg.0.log attached. I'm paying attention to lines 269 295 327 369 377 380 and 381

269: (II) MACH64(0): Modeline "1920x1080"x0.0 148.50 1920 2008 2052 2200 1080 1084 1089 1125 +hsync +vsync (67.5 kHz)
295: (II) MACH64(0): Modeline "1920x1080"x60.0 172.80 1920 2040 2248 2576 1080 1081 1084 1118 -hsync +vsync (67.1 kHz)
327: (II) MACH64(0): Estimated virtual size for aspect ratio 1.7931 is 1920x1080
369: (II) MACH64(0): Not using default mode "1920x1440" (insufficient memory for mode)
377: (II) MACH64(0): Not using driver mode "1920x1080" (bad mode clock/interlace/doublescan)
380: (II) MACH64(0): Not using driver mode "1920x1080" (bad mode clock/interlace/doublescan)
381: (WW) MACH64(0): Shrinking virtual size estimate from 1920x1080 to 1280x1024
