No, I'm not "wondering" this because of anything. I'm just asking a simple question, because trying to game at 4K resolution (at 30fps) is rediculous and it would be extremely nice to have a Radeon Graphics card such as the R9 290X (that would support HDMI 2.0/2.1) and would hopefully support 3840x2160p 120Hz (120fps) because 4K at 30fps is rediculously slow and laggy. Even HDMI 2.0 only supports 4K at 60Hz, so I was hoping that AMD (since they are a member of the HDMI Forum) would try to bring forward a 2013/2014 graphics card that supports HDMI 2.1 (4K resolution at 120Hz and possibly even 240Hz for 3D gaming at 120Hz).
The R9 290/290X are brand new graphics cards, and I was just curious as to whether or not they support HDMI 2.0 (and whether this can be implemented with a firmware update?) or whether we need to wait for a new (hopefully upcoming) graphics card with HDMI 2.0/2.1 ports on it, so that we can use it to drive monitors/displays at full 4096x2160p120 or 3840x1920p120 resolution.
We use high end graphics cards for Battlefield Visualization, and even the highest-end R9 290/290X still doesn't seem to have native support for 3840x1920p120 resolution.
I was just hoping that AMD/Radeon would be coming out with a newer high-end graphics card in the very near future (or possibly have a firmware update for the current R9 290/290X) that would support HDMI 2.0 (and possibly a future HDMI 2.1?) and hopefully support faster refresh rates (faster frame rates) such as 120fps at 4K resolution.
Even a temporary solution, such as supporting 3840x2160p120 temporarily by using some type of "collage mode" where two HDMI 2.0 ports (running at 3840x2160p60) could be used together in tandom (bonded using two HDMI 2.0 ports) to produce a resolution of 3840x2160p120 until a formal HDMI 2.1 specification could be passed.
It's just painful trying to develop for 3D 4K resolution at extremely fast frame rates (120fps) which is what gamers are used to. 30fps is fine for just plain text, and 60fps is usable, but when you need at least 120fps (so you can run 60fps x2 in 3D), it's very difficult finding a graphics card that can support 120fps (120Hz) at 4K resolution.
I was just hoping that the R9 290/290X would be capable of this (via firmware update), but it might simply not be a fast enough graphics card (but even two or three in a CrossFire configuration would seem to be fast enough) but we just need AMD to come out with some type of firmware update (and driver update) that would support 3840x2160p120. (Possibly by using two HDMI 2.0 ports bonded together, simply by connecting two HDMI 2.0 cables to two HDMI 2.0 ports on the R9 290X to two HDMI 2.0 ports on a customized display).
What I am asking is are there any plans in the very near future (late 2013? or early 2014?) to release an AMD 300/300X video card (even a prototype card) that supports HDMI 2.1, and DisplayPort 1.4 ports and supports 3840x2160p @120Hz and 3840x2160p @240Hz with TrueHD Audio (for 3D gaming at 120Hz)? PCIe 4.0 support would be very nice as well.
For high-end Battlefield Visualization (using satellite imagery overlayed over DTED data to create high-resolution 3D visualization and real-time fly-throughs) at 4K resolution, we really need MUCH better graphics cards and I was really hoping that AMD could/would release something soon (a firmware patch?) that would support 3840x2160p @120Hz and 3840x2160p @240Hz with TrueHD Audio (using dual R9 290/290X graphics cards in CrossFire mode) for real-time 3D battlefield gaming/visualization at 120Hz.
In theory, it should be possible, but it would be up to AMD to implement such a feature though (via firmware/driver update) to support 3840x2160p120 and 4096x2160p120 resolution and higher frame/refresh rates.
With dual R9 290/290X cards running in crossfire mode, it would seem to be plenty of processing power, it's just a matter of driver/firmeware support (and using two HDMI 2.0 cables/ports) as a temporary fix, until AMD can work to get some type of faster HDMI 2.1 specification passed through HDMI Forum (which AMD is a member of). Hopefully we can see HDMI 2.0b very soon, and hopefully it will support 120Hz and 240Hz at 4096x2160p and 3840x2160p screen resolution at 120fps.
