I'm sorry to hear that, I would recommend double checking if your graphics card can output that resolution and refresh rate. Especially if you are running dual monitors. Also, I would recommend checking for driver updates to see if it will help the issue. Please feel free to contact us at firstname.lastname@example.org with a detailed summary of the issue you are experiencing and our knowledgeable Technical Support staff would be more than happy to assist. Thank you

Cable works great for connecting my cable box to my TV. Note - this is a heavy duty cable, so it's not as flexible as typical HDMI cables.
