From 2016/10/09 to 2016/12/13, my desktop and monitor worked perfectly. Since 2016/12/14, they show black-outs of 3.2 seconds zero times to about 10 times per hour. They are not shorter than 2 sec nor longer than 4 sec. The sound stops simultaneously with the black-out. On some days, the black-outs do not occur for more than 8 hours. Horizontal black line (through-out) noises within the bottom half of screen can be frequently observed right before the black-out. I also experienced whole-screen shakings when I moved between cells on Excel. I tested my monitor with another HP notebook (HP Pavilion Gaming 15-ak051tx Intel HD Graphics 530 2015/12/21 126.96.36.19960) for 4 days and a black-out could not be recognized (I played music to hear whether the black-out occurs when I leaved my notebook).
I returned my monitor to my desktop and examined several different versions of 530 drivers. First 6 digits of version numbers shown on the download site ( https://downloadcenter.intel.com/ja/product/88345/Intel-HD-Graphics-530 ) and those which of Device Manager do not match. Maybe Microsoft and Intel manage the version numbers differently. So, I only name the last 4 digits to indicate which driver I use. 4552 (beta) and 4542 result in the black-outs within 11 minutes after booting Windows up. 4539 (beta) results in black-outs within 30 minutes after booting. Since 2017/01/04, I use 4352 and the black-out have not been recognized (6 days, but I worked outside often). My question would be that should I use 4352 forever trying disabling auto-updating, or should I engineer Windows and Intel HD Graphics settings to utilize for example 4542?
