Here's what I'm trying to do... I have very large interactive SVG-based visualizations. I would really like to display these visualizations as large and with as many pixels as I can. My budget is ~$5,000. Right now we're using 30" 2560x1600 monitors. Would love to go to 55" or 65" at 3840×2160. But its an interactive computer display, so 30 fps is a bit low.
From the research I've done, I can go with a Sony Ultra HD set and wait for the HDMI 2.0 firmware upgrade, or go Samsung and wait for the hardware update of the connector box, or (pre-order?) the Panasonic with HDMI 2.0 and DisplayPort support. I've looked at the Asus 31.5" ultrahd monitor, but that just gives more ppi without much more viewing area.
But that solves just the display portion. Then I need a graphics card capable of driving 3840x2160 over HDMI 2.0 or DisplayPort or it appears with the Asus monitor there's a way to use dual-monitor outputs and EyeFinity and connect both HDMI to the monitor.
The AMD R9 290 and 290x seem capable of driving over DisplayPort, but the early reviews suggest they run super-hot.
So I'm stuck on five questions:
1) Can anyone confirm if the R9 290 (or any other graphics card) can drive 60hz to the Panasonic?
2) Can anyone comment if any of the existing TVs would take dual HDMI input like the Asus monitor?
3) Does anyone know if the R9 290 runs super hot even if you're not driving polygons and textures through the 3D pipeline?
4) Are there any HDMI 2.0 graphics cards out there yet?
5) Is there any other configuration I'm missing that might meet my objectives?
