How to properly connet a 4ktv system

Hello,

There is something bothering me lately About how to connect a future 4k monitor using high speed hdmi cable with Ethernet and enjoying 60hz.

first: my GPU is Radeon™ R9 280X GAMING 3G which has 2 displayports 1.2, and one hdmi 1.4a .

One of my possibilities is Philips BDM4065UC, which Supports 4K res with any HDMI but only at 30hz, while display port 1.2 has 60hz.

the problem is that I already planted an HDMI cable in the wall so display port is not an option now.

what can I do to gain the 60hz? is it possible to bring a DP 1.2 adapters to HDMI ? to use on both sides? (the GPU and TV) will it be the same?

The HDMI at 30Hz is expected.

In reply to: How to properly connet a 4ktv system

Not to repeat what's on the web but as long as you stay on HDMI it should be 30Hz. Gamers tend to move the GPU back to 1080p and let the TV upscale since gaming on even the 280x may not get enough frames per second (unrelated to display rate.)

I would not buy this

If we use HDMI at UHD then it's 30Hz so no gain there. Sounds like a mess to me as well as a waste of green.

HDMI 2.0

In reply to: I would not buy this

In case that I already have a GPU with HDMI 2.0, will there still be a problem with the 26ft long cable? or in other words there is no sure way to use that 26 ft cable for future 4K tv ?

I can not tell you that.

Cable quality today is all over the map. You will have to test it out.
https://www.google.com/search?q=hdmi+2.0+frame+rate finds the frame rate will go up but your 280X pushing UHD will not game at 60 FPS.

I guess you are new to this and as of last year it took a trio of Titans to break the 30 FPS mark. No leap forward here as I compare your single 280X to a Titan.

You will not be gaming at UHD and be happy unless you pull back to 1080 and let the TV upscale and even then it's iffy.

Folks have tried this. You seem to be ignoring the prior findings.

No gaming

I never said anything about gaming, only about 60hz.

And why I check gaming results?

In reply to: No gaming

Because it can help us figure out video playback frame rates.

Your video card does not do HDMI 2.0 from what I can find so it's a dead end.

As i said

If in the future i'll have a gpu with hdmi 2.0 how can I be certain that it could transfer the 4k 60hz before I'm buying new tv?

Remember

In reply to: As i said

There is "transfer" and there is rendering frame rate.

The transfer will be 60 across all the 2.0 cards but given the current state of the art rendering to 60 at UHD may be an issue. For now I let the TV upscale rather than the card.
