The question is definitely frequently asked. done. Why doesn't Haiku let me use my monitor's resolution? (http://www.haiku-os.org/about/faq#12) Most likely, Haiku is using the VESA driver. As with any other VESA driver, it has limitations. The problem is that the VESA driver cannot configure an arbitrary resolution. Even if it recognizes the needed one from the monitor info. It can only *pick* (quite literally) one resolution from a fixed list, the VESA BIOS list as manufactured in your graphics board. It cannot configure the mode on the chip as a special graphics driver can. How can I check which graphics driver is being used? (http://www.haiku-os.org/about/faq#14) From within Terminal, you can run listimage | grep accel If "vesa.accelerant" is shown amongst other text, then Haiku does not have a dedicated driver for your graphics card and instead is using VESA. Luckily, Haiku's VESA performance is rather impressive.
