I'm not 100% certain but I don't believe it has switchable graphics. I see nothing for a built in gpu, in the system or in the bios. The adapter I'm using is bizlink TK041 https://www.amazon.com/dp/B0041OB2RG/?tag=mtests-20#ad I installed the hdmi.dat file and I still have the same results. Along with enabling and disabling the extension block. UPDATE So I unpatched the driver and started over. I set a resolution of 3840x2160@15hz to keep it under the limit and it worked... I can get up to 18hz before it stops working. However, patching the drivers and doing 3840x2160@19-30 doesn't work. UPDATE2 StarTech.com DP2HDS came today. Same results as above. I know for sure that this is an active adapter. UPDATE3 The bizlink TK041 I believe is a passive adapter. When I view edid information in CCC switching between the two shows adaptive and passive. Still doesn't seem to want to go past the 165mhz clock speed, even with the patch. Makes me wonder if it's a Raedon vs FirePro issue... would that affect the amd patcher you created at all? More Info... I tried plugging directly in through my hdmi out port, thinking it wouldn't work, but it did, 3840x2160@18 ... I even tried using the docking station + DP>HDMI both adapters, same results... and that's about all I have. Not sure what else to do or try. More research... from displayport wiki In January 2013, a new VESA specification was released called DisplayPort Dual-Mode Standard version 1.1, which brings dual-mode capabilities on par with HDMI 1.4, allowing a TDMS clock rate of up to 300 MHz... -and- A notable limitation of Type 1 dual-mode is that it can only transmit single-link DVI (and HDMI), as the number of pins in the DisplayPort connector is insufficient for dual-link connections. Also, it is limited to a TMDS clock rate of 165 MHz. As a result, an active converter is needed for Dual-Link DVI, HDMI 1.3+, and analog component video such as VGA. Well I have both passive and active, neither go above the 165mhz clock rate. FINAL UPDATE I just recieved Accell B086B-003B which is a Type 2 active adapter. Everything works perfectly! https://www.amazon.com/dp/B00ESFF5O4/?tag=mtests-20#ad |
