A 39-year veteran of the video display industry - helped evolve early consumer TV technologies for use in new applications such as computer monitors, arcade games, and HDTV.

Mark began his video career at Motorola - helping the company make the transition from Quasar consumer televisions to computer monitors. There, Mark developed original tools (video signal generators, video distribution systems, and deflection yoke & CRT testers) for the - then fledgling - computer monitor manufacturing business. By 1980, through Mark's efforts (and those of other pioneers), Motorola's Display Systems Unit had become the largest manufacturer of computer monitors in the US.

In late 1979, Mark was approached by a small rep firm called Quantum Sales, to design a commercial computer video signal generator. Quantum Sales' business plan was to sell modified consumer TV chassis to major arcade manufacturers in the Chicago area and use sales commissions to start a new video test equipment company called Quantum Data. Mark designed Quantum Data's initial product, Pac Man came, and the rest is history. Over time, Quantum Sales was disbanded, Mark was made Quantum Data's Chief Technology Officer, and the company evolved to become one of the world's leading suppliers of test equipment for the design, installation, and service of audio, visual, and control products. Today, Quantum Data instruments can be found in the design laboratories and production facilities of leading IT and CE product manufacturers worldwide.

Mark is a member of IEEE, ACM, SID, AES, SMPTE, VESA, CEA, and the HDMI Forum. He is a former co-chair of CEA's R4.8 WG7 & R4 WG16 workgroups, which penned ANSI/CEA-861 (a platform for A/V interfaces such as HDMI and DisplayPort) and ANSI/CEA-2038 standards. Mark also chaired the HDMI Forum's test subgroup responsible for the HDMI 2.0 compliance test standard. Long ago, Mark chaired the DDWG DVI compliance & interop workgroup.
