4K on PC with Displayplort 1.2 GTX 660 Ti

To work (many windows open at the same time) to make the Super 40 inches in conjunction with the 4K resolution.
At first I was worried because my relatively old graphics card (Asus OC Cu 2 GTX 660 Ti) has no HDMI port, let alone an HDMI 2.0 (which is available only from GTX960 and the cost at the time, more than 200 euros and have less than 20 % more power than my card).

I got myself to the TV so appropriate adapter:
- Moshi Mini DisplayPort to HDMI Adapter (4K) (from HDMI 2.0 to Mini-DisplayPort)
- DELOCK Adapter DP-St> DP mini-Bu (from mini DisplayPort to DisplayPort 1.2)
and a relatively short cable (have read somewhere that the longer HDMI cables, is more support lower resolution):
- 1.5m - Ultra HD 4K HDMI cable 1.4a / 2.0

Result:
to 1920x1080 (ie Full HD) with 60Hz
then all intermediate resolutions with 30Hz
and (miraculously):
4096x2160 (UHD 4: 3) again with 60Hz
3840x2160 (UHD 16: 9) again with 60Hz

Bin so far very satisfied with this result,
enough to play full HD, work and watching movies on PC I UHD (4K).
