Graphics card with weird red artefacts (SuperMac Spectrum Power•1152)


Recommended Posts

SuperMac Spectrum Power•1152 graphics card with weird red artefacts (the HD icon labels) that appear after being connected to an AppleColor High-Resolution RGB Monitor for 5–10 min. (The card works great with an Apple Studio Display.)

 

Sound familiar?
