How to connect a TV with a third display so that there is sound?

Question

Video cards

Hello!

Three displays are connected to the Radeon HD 7850 video card: 1) LG 1900R 1280x1024 monitor (there is only a DVI input) 2) Asus VP248H 1920x1080 monitor (there are VGA and HDMI inputs) 3) Hyundai HF237 1366x768 TV (also VGA and HDMI inputs).

The video card has DVI, HDMI, DP outputs, it supports 2 independent channels, so all three displays work simultaneously only if I connect the TV via a VGA cable (cable of poor quality) through a DP-VGA adapter (CableExpert model A-DPM- VGAF-01). I need to make sure that sound is also transmitted to TV, i.e. connect TV via HDMI. As I see it, there are 2 options:

1) Buy a good VGA cable (up to 2 m, all displays are close), connect the Asus monitor via VGA through an adapter. There are doubts that even with a good cable, the adapter will pull FullHD, well, that's okay, maybe it will. But, judging by the reviews, now it’s hard to find a normal VGA cable. Can you recommend any proven one, with ozone, for example?

2) Buy an active DP-DVI or DP-HDMI adapter to connect one of the monitors through it and free up one RAM-DAC on the video card. But here it’s even more difficult, I can’t understand which adapter is active and will keep all three monitors working. Please recommend a suitable adapter.

Perhaps there are other ways? Tell me please.

Thank you!
