DVI limits the clock frequency to 165 MHz (the first number on the
mode line). You may be able to go beyond that by using a DisplayPort
cable instead.

Yes, that actually worked! I tried first at 50Hz and it did not, but
33Hz is working at 2560x1440 (but not in console however, I don't know
how to specify a different mode there, if it's even possible).

I think you should try another monitor if at all possible. Perhaps your
monitor just goes into power-save mode with an incompatible signal. On
mine, it pops up a message that asks me to set my video card to "2560 x
1140 60Hz" which, according to the dmesg, it should already be:

   radeondrm0: 2560x1440

My xrandr shows the 2560x1440 mode at 59.95Hz, I'm assuming that's close
enough to 60Hz that it should work? Or could that be the problem? The
highest I can get working is 2048x1152.

It looks like xrandr reports are not helpful. I think you shoudl
enable the onboard card, find a second monitor from a friend and try
to boot with both monitor connected. Then you can debug.

Without parameters, via ssh:

$ xrandr
Can't open display
$ echo [$DISPLAY]
[]

This is after logging in and typing startx on the keyboard, with a
blank monitor. I've also tried launching startx via ssh, with the same
result.

In the BIOS, "Primary Graphics Adapter" is set to "PCI Express". When
switching it to "Onboard" and plugging the cable into the onboard DP,
the boot message and the BIOS setup are shown and the display
functions at 2560x1440@60Hz.

When the setting is "PCI Express" the OpenBSD boot messages are
displayed through the PCI adapter (only). A brief moment after the
"scsibus4 at softraid0: 256 targets" there is no signal anymore,
neither on the PCI adapter nor the on-board one. (This happens no
matter whether xenodm is on or off.)

I recall I tried once a dual monitor setup using an onboard graphics +
another plugged in card. I don't remember exactly, but I think the
boot message was shown one the onboard graphic card only or on both
monitors. I was concerned about this behaviour then I got over it
since in X all was ok.

Did you disable the onboard card from BIOS? What options do you have for this?

Try connecting a lower-resolution monitor and see if it works, if you
have one.

I have found that my dual 2560x1440 monitors, connected with DVI->HDMI
cables, are not capable of 2560x1440 I believe this is due to limits of
DVI. However the monitor and/or the card does not realize this and
reports 2560x1440 60Hz as the "preferred" mode.

I have a ATI Radeon HD 5870 card.

If I connect one monitor with an HDMI cable I can see the console. With
two monitors connected with DVI->HDMI I do not. I have to do a "blind"
login then run "startx" and all is well.

Apologies, I have to revise the results from my previous message (by
accident I had the cable connected to the onboard video).

In fact xrandr does detect the DisplayPort connection:

However, the screen remains blank. Changing the resolution doesn't help either:

that for now the answer is no, it's not configurable.

Re: Blank screen after boot with Radeon HD 5450

I tried your suggestion of logging in with the keyboard while the
screen is blank and then typing "startx". Then logged in via ssh:
$ DISPLAY=:0 xrandr
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 8192 x 8192
DisplayPort-0 disconnected primary (normal left inverted right x axis y axis)
DVI-0 disconnected (normal left inverted right x axis y axis)
VGA-0 disconnected (normal left inverted right x axis y axis)

The DisplayPort cable is connected.

Still it seems that the problem is not with X, as it occurs even with
it is disabled.

I see this every time after a fresh install on a Radeon HD 6450, too.
Login and reboot (as with eyes shut) has always been successful.

By the way, recently, I had a nice effect: I forgot to attach the
monitor cable before boot, hence the usual 1600x1200 resolution was not
detected, and the standard 1024x768 mode was chosen. After connecting
the monitor cable, as a result I got the neat SunOS console font based
on the lower resolution (getting back the full resolution in the
consecutive startx session). I like it very much, since it was better
readable and not that tiny. Is there a way to choose lower resolutions 
for radeondrm console using some suitable configuration file?


With best regards,
Jens
