Some solutions seem to be to have a element of two which is fairly substantially assured to close up dying on you. In the scenario of the 2015-vintage Wacom Cintiq Companion 2, this turns out to be the so-identified as Athena chip, which switches the display screen enter amongst the HDMI port and inner show controller. This lets for use in both of those standalone method (pill), as effectively as companion method, the place it acts as a drawing tablet for a related Personal computer. When confronted with this kind of a faulty gadget, [neutrino] located and utilized a very simple take care of: bypassing the Athena chip altogether.
This deal with is encouraged by the Maintenance Preservation Group’s wiki website page on the topic, noting that this will completely disable its use as an external exhibit devoid of added repairs to recreate the features of the eradicated chip. This STDP9320 (PDF) aspect by ST Microelectronics is explained as a ‘Premium higher resolution multimedia keep an eye on controller with 3D video’ and contains a huge assortment of video clip scalers, a HDMI receiver, DisplayPort (like embedded DP) help. With this take care of, the Cintiq Companion 2’s Intel CPU’s graphics main is right connected to the display’s eDP input, along with a assortment of voltages and permit pins.
What the actual motive is for the STDP9320 dying following a handful of yrs with what seems to be some sort of interior energy failure or quick, but this bypass take care of at minimum restores standalone performance. Sourcing a substitute for this obsolete IC seems achievable, but a major gamble. Unfortunately, it would seem to be that this Wacom unit will no extended be a companion for significantly lengthier.
