Installed new GPU and recommended resolutin is 3840 x 2160 but keeps going back to 1920x1080

I just installed MSI GeForce GTX 1050 Ti [1] replacing [ASUS GeForce 9500 GT][2]

I know the new card can run 4k and my display is a 4k tv.

When I try to change the screen resolution to the recommended setting 3840 X 2160 and press apply okay. It states the resolution is 3840 X 2160, but when I go back to my screen resolution setting I see my resolution is back to 1920 x 1080.

I also went to Nvidia Control Panel and try to change the resolution to 4k x 2k, 3840 x 2160 (native) the screen goes black and reappears and res. setting is still 1080p, 1920 x 1080

Not sure why I can't seem to make my computer to display in 4k.

This is the rest of my specs:
[VIZIO SmartCast™
E-Series 43" 4k version Display][3].
[Intel Core i7-870 Lynnfield Quad-Core 2.93 GHz CPU][4]
[ASUS P7P55D-E Pro LGA 1156 Motherboard][5]
[Western Digital Black WD1001FALS 1TB HDD][6]
[Sony Optiarc CD/DVD Burner][7]
[CORSAIR TX Series CMPSU-750TX 750W PSU][8]
[Rosewill CRUISER Black Gaming ATX Mid Tower Case ][9]

  3. That won't work. The cable can't push enough data for 4k

  4. For what I read HDMI cables can support 4k or why would they be used on 4k hd tv

    Guess I should have been more specific. It requires HDMI 2.0 or higher to use 4k check exactly what cable you have
