Default Re: Sony KV-A2942U very soft focus in middle of screen

Sony were very quick to incorporate their experience in the design of professional monitors to their domestic receivers particularly for the US market.

Comb filters, 10Mhz video response IC video output. CRT based video output long before they were adopted by others. Specialist geometry IC to match the Trinitron CRT design, fine pitch aperture grill which really did make a difference, velocity modulation, computer CRT yoke design and so on.

In many ways the limiting factor was the broadcast system. Whilst DVD and later Blue Ray made a vast difference, squeezing extra information out of a system designed for 4:3 picture ratio then stretched to 16:9 was a tough nut to crack.
