Hello. I'm evaluating buying a new monitor, since the one I'm using looks willing to die. I searched a lot before posting, but while the "generic" information is confusing, it's hard to find FreeBSD-specific facts. Is there a way I can be sure a certain resolution will be supported by my graphic card? Specifically, I've got a Radeon card integrated on my mother board: > # pciconf -lv > ... > vgapci0@pci0:1:5:0: class=0x030000 card=0x17041565 chip=0x97101002 rev=0x00 hdr=0x00 > vendor = 'Advanced Micro Devices, Inc. [AMD/ATI]' > device = 'RS880 [Radeon HD 4200]' > class = display > subclass = VGA > hdac0@pci0:1:5:1: class=0x040300 card=0x970f1002 chip=0x970f1002 rev=0x00 hdr=0x00 > vendor = 'Advanced Micro Devices, Inc. [AMD/ATI]' > device = 'RS880 HDMI Audio [Radeon HD 4200 Series]' > class = multimedia > subclass = HDA > ... > # cat /var/log/Xorg.0.log > ... > [ 128.142] (==) RADEON(0): Depth 24, (--) framebuffer bpp 32 > [ 128.143] (II) RADEON(0): Pixel depth = 24 bits stored in 4 bytes (32 bpp pixmaps) > [ 128.143] (==) RADEON(0): Default visual is TrueColor > [ 128.143] (==) RADEON(0): RGB weight 888 > [ 128.143] (II) RADEON(0): Using 8 bits per RGB (8 bit DAC) > [ 128.143] (--) RADEON(0): Chipset: "ATI Radeon HD 4200" (ChipID = 0x9710) > ... > [ 129.711] (II) RADEON(0): EDID for output HDMI-0 > [ 129.711] (II) RADEON(0): Output VGA-0 connected > [ 129.711] (II) RADEON(0): Output HDMI-0 disconnected > [ 129.711] (II) RADEON(0): Using exact sizes for initial modes > [ 129.711] (II) RADEON(0): Output VGA-0 using initial mode 1600x1200 Contrary to what is stated above, my MB does not have an HDMI connector, only D-SUB and DVI (DVI-D I believe). Is it possible that HDMI from the logs mean DVI on my board? Or is DVI not show because it's unsupported? What will be the maximum supported resolution (via D-SUB or via DVI)? Will I be able to run at 1920x1200? Via D-SUB or via DVI? bye & Thanks av.
