I have read many problems with Monitors / TVs and the Intel GPU drivers.
2 years ago, I had an issue where the Vista H.P. Intel GPU driver will not display desktop on big screen TV. But same TV and different system specs with same manufacturers and it works. Some later after 2 years, I read Maintenance Engineering post could not resolve problem and keyword 're'.
My conclusion today is the problems are non driver based and not liable under Intel Support.
And what is an Intel 'motherboard with spec details ?
