GEX 770 OC into Viewsonic - nothing but cursor.
Viewsonic VX 2880 ML 28" 4K
Graphics card is by PALIT and has DER R on spec somewhere.
The graphics card, via HDMI, reports if one of its dedicated power lines is pulled. So some life in there. However, the computer does not seem to go through POST checks. So the stuff on the screen just generated by the card, I suppose.
Screen shows blinking cursor top left and two letters bottom right. RC I think.
VGA on computer is disabled when card slotted in so no help for booting/driver load. There seems to be no way to install drivers etc., and there's the danger of locking oneself out blind to reset things again.
Any ideas for a next step of diags?
