Getting a black screen with the shaders or all the time? Which driver? DRM/KMS only works with nouveau, not with the nvidia binary driver. Being a video card 6xx series, there should be no problems with OpenELEC Nvidia Video Drivers (i don’t need nVidia_Legacy build). I bought a ZOTAC ZT-60604-10L yesterday on Amazon to resolve this problem and use my Lenovo ThinkCenter M58 (Type 7359).

Obviously, the GT 610 Zotac is low-profile with passive cooling. To my surprise the Zotac has produced a PCI video card ( not PCI-Express) Nvidia Geforce GT610 (model: ZT-60604-10L and model: ZT-60606-10L). The problem is that many post-2008 mini PCs have a PCI slot and no one PCI-E or AGP. RPi’s analog video to CRT can’t run at native resolution (it’s always 480-interlaced), and it’s composite rather than s-video, so it’s not that great, either. Simple scanlines are probably your best bet after that. As far as I know, you need HD4000 or better integrated graphics for any of the CRT shaders to get full speed at 1080p, though crt-hyllian-fast and crt-easymode are the most likely to work.
