Recently I purchased the retail DH87RL.
Issue is that during BIOS the internal graphics is sending a signal on DVI and HDMI that is incompatible with my monitor. Monitor (LCD, Dell, probably 5 years old), gives a message indicating there is a signal, but that either the resolution or timing is incompatible. So the monitor is blank until Windows finishes loading and shows the loaded Windows screen.
I tried getting it to work by plugging it into my receiver (for my HDTV) and had the same issue (again receiver/HDTV are about 5 years old).
I took it into my group's lab in Jones Farm 2 and found that it displayed correct on the two monitors I tried in the lab.
I've tried looking at the product documentation and Googleing to try to find what resolution it is trying to use that isn't supported by the monitor, but I've been unsuccessful. The monitor supports a fairly high resolution (2048x1152 @60 Hz) so I'm baffled at why there is a disconnect in what the BIOS is sending and what the monitor can support.
I'm fairly disappointed that such an essential element of the board has such an issue. I appreciate the advancements being made in the visual BIOS, but it shouldn't come at the cost of basic functionality.
Background Details:
- I tried both DVI and HDMI ports on the Dell SP2309W monitor, without success.
- Tried receiver Onkyo TX-SR606 / TV Samsung LN46A-550, without success.
- A third party graphics card will work when plugged into the PEG slot
- Two monitors Dell & Asus worked in the JF lab
- Using the latest posted BIOS (as of 10/20/2013)
