    AMD r9 270 problem

    Hi I have a XFX Double D R9 270 with 1x DP, 1x HDMI and 2x DVI-Dual Link. I have (3) Monoprice WQHD monitors, two of which is connected directly to the graphics card through DVI-Dual Link. The third is connected via an active DP to DVI-Dual Link adapter. I was using a HD 5850 before the upgrade so I know that this configuration works. Here's what I have done so far: 1. I modified the kexts with the correct device ID: 0x6811. 2. In Clover I have InjectATI enabled. 3. I also set the FrameBuffer to Hamachi, replaced the framebuffer with the following: 00 04 00 00 04 03 00 00 00 01 00 00 22 05 01 02 DP 04 00 00 00 14 02 00 00 00 01 00 00 11 02 05 05 DVI-DL 04 00 00 00 14 02 00 00 00 01 00 00 10 00 03 06 DVI-DL 00 08 00 00 00 02 00 00 00 01 00 00 12 04 02 03 HDMI The values are based on Vlada's tutorial and the attached ROM file downloaded from https://www.techpowerup.com/vgabios/151666/xfx-r9270-2048-131119.html So far, only the monitor connected to the DP works. For the ones connected to the Dual-Link DVI ports, one does not receive a signal at all and went into sleep, the other one displays a black screen. However, all three monitors show up in System Information. Wonder if anyone has the same graphics card and is able to help? Thanks.
