I recently got a samsung 55'' 4k TV, model UN55HU7250FXZA, and was hoping to hook it up to my computer as an additional display occasionally.
I've got a GTX 780 with all the latest drivers installed, and I bought an hdmi cable long enough, (http://www.amazon.com/BlueRigger-High-Speed-Cable--wall/dp/B004GW25WY/ref=lp_202505011_1_12?s=audio-video-accessories&ie=UTF8&qid=1422742286&sr=1-12)
Yet when I got to plug the TV in, my computer is not sending a signal, but here is the weird part, if I plug in the tv as my only display, and then I boot my computer,
I am able to see the ASUS start up screen and I can even go into the bios, but as soon as you would usually see the windows login screen, it goes back to
"no signal"
Could this be an issue with Windows 8.1? I just think it's weird that I'm able to see the ASUS bios, but nothing afterwards?
