Nahodou jsem narazil na zajimavou informaci... Takze ani R9 nezvladaji tri ruzne monitory bez DP. Cili napriklad moje konfigurace 2*1680x1050 (DVI) + 1280x1024 (HDMI) by patrne na radeonech nesla. Eyefinity funguje, protoze tam se pouzivaji stejne LCD.

The 280, 270, 260, (and presumably 250) are the same dies as their predecessors and have three TMDS links but still two TMDS clock generators. AMD has only modified their VBIOS so that two TMDS displays with the same timings can share the same clock generator. Even then, AMD software limits this capability to only work when all three TMDS outputs have the same clock signal.

This means that you can only use all the outputs when you have three identical TMDS monitors.

NVidia's solution is much more flexible since it has three clock generators and three TMDS links, so all the displays can be mismatched without issues. The current phrasing implies that AMD has similar display output capability as NVidia, which is not true. With mismatched monitors, AMD cards can still only use two TMDS outputs. I suspect it may cause a few headaches for people who buy these cards expecting all the outputs to work with mixed monitors when in reality they won't. Maybe the R9 290 series will fix this problem.

270 a 280 je to jasne, pretoze su to iba premenovane stare karty, ale popkial viem, tak 290 by problem mat nemala.. 260 neviem.

Nojo, 290 je vlastne v tomhle ohledu trochu pozmenena. V recenzi na diit dokonce fungovalo i podtaktovavani se dvema LCD, ale mozna to byla jen nahoda, protoze ve vsech ostatnich recenzich je spotreba se dvema monitory citelne vyssi. Uz aby tady byla nova 20nm generace, kde snad uz budou vsechny tyhle funkce dotazeny k dokonalosti.

ja inak velmi zvazujem eyefinity system, ale presne cakam na mainstreamovu grafiku ktora bude mat bud 3x displayport, alebo bude vediet dvi+dvi+hdmi bez toho aby sa tam konali nejake redukcie (ci uz externe alebo interne).
