Hello friends. Nice to see you. I have some troubles with an equipment and I need your help. First, the description: APU AMD A6 6600k without OC 2 * 4 GB G.Skill RipjawsX F3-12800CL9D-8GBXL Kit un dual channel Motherboard Asrock FM2A78M-HD+ Monitor: ASUS VS229NA-W Firmware 2.5, 256 MB or 512 MB share memory The monitor is DVI-D and I am using a cable with this pin out (it was working before)  I build a computer for a friend with those parts. He was using and Asus monitor with DVI and a Tv with HDMI like a mirrow (same image). About one week ago he lost the signal on DVI monitor and in the HDMI because is a mirrow and never the HDMI signal works for the BIOS. I changed the cable, the monitor and nothing, the DVI (alone or together) device is not working. Not signal, neither the Bios works. If I switch to the VGA output, everything works great, alone or together with the HDMI.. Then, I thought, is the Motherboard with as problem in the DVI output. I got today a new motherboard (the same model), I switched and.. surprise... not signal on DVI... Now, I dont know what to do... Anybody have any ideas? The CPU? |

That what you pictured there is a Single Link DVI-D cable. It should work. Although, it's known as an inexpensive alternative to a true Dual Link cable, and thus may not. A Dual Link DVI-D cable has pins filling in the gap(s) between the two sets of nine pins in the picture above < id="kpm_plugin" ="application/x-KPMPlugin">

Yes my friend, but It was working with that cable. If I put other computer (same motheboard/cpu/memory) with that monitor and that cable its works. The problem is not on monitor/cable. If I change the computer to other monitor, it doesn't work. |

Hmmm, how many video cables do you have connected to the computers rear I/O ports? < id="kpm_plugin" ="application/x-KPMPlugin">

Just one. the DVI. I found the solution, it was on the CPU APU. First, I exchanged the motherboard for other, same model, still the problem. After, I replaced the CPU /APU in the new motherboard for the same model, new one, and fixed..... The APU wasn't sending signal to DVI..... Thank you. |
