I got the GeForce GTX 1070 graphics card and was using it through just an old tv that I've always used for my PC. I decided I wanted to get an acual computer monitor to get the most out of the card. so I went out and bought an Acer (H6 series 23" IPS LED HD Monitor) and was going to use the DVI-D capability. so when I got home I turned everything off and setup the monitor with the DVI and removed the HDMI from my GPU. I then powered on the monitor and then the computer (in that order) and got the ASUS boot screen. the monitor then went black, searched for a signal, and then said no signal right before going into a sleep mode. I then attempted to manually switch the source to DVI but it still had a no signal screen. I then attempted going back to my TV and I couldn't get signal even using the HDMI like it was set originally. so I have now removed the GPU and am using the HDMI off of my Motherboard. any help at all would be greatly appreciated for I would like to use my new GPU.
