About a month ago I bought an HP Pavilion desktop system with Intel HD 630 integrated graphics. About a week ago I started noticing very random "glitches" - screen flicker or jumps. On several occasions it got quite sever, and one (or both) monitors went totally black. As far as I can ascertain, there is no "trigger", it just happens. It has happened under various conditions (temp, software, on web, off line, etc.). I am using two ViewSonic VX 2257 MHD 24" monitors (primary connected to the HDMI port, secondary to the D-Sub 15 pin port). After searching the web, I read an Amazon review by a guy that bought 13 of these monitors for his office. He wrote that he had the exact same issues with all the monitors, and ViewSonic offered no help. Somehow (he did not elaborate) they traced the issue to the graphics driver (brand unspecified). Sooo... I was wondering if there is a known issue with these monitors and the HD 630 driver?
Also, since I did not notice this issue for a few weeks (which can be deceiving because I may have just not seen it - it is very random) and there was an Intel update that was applied around Nov 8th (shortly before I noticed this issue), would it be advisable to roll back the driver? Are older drivers available for download?
I realize there are many variables here, and I saw your post about using a chart (frankly I was confused about how to use it) to provide info. Here is my system info:
Windows 10 Professional (x64) Version 1709 (build 16299.64)
HP Pavilion Desktop PC 570-p027
3.00 gigahertz Intel Core i5-7400
12 GB DDR4 RAM
128GB SSD (primary)
2TB SSD (data)
2TB & 800GB USB drives
4TB WD MyCloud Home Duo
The ViewSonic Display Drivers are current.
This issue usually is insignificant (i.e. just an inconvenience), but maybe 5 times so far, one or both monitors are unusable for maybe 10 minutes. I worked with HP for over an hour running various tests, and the computer itself seem faultless (the screens broke up during a test of the video, but the tests all passed, so I thought the issue was the monitors, which seemed unlikely since they both do the same stuff - albeit NOT at the same time usually - however when I found a guy with 13 of them doing the same thing, I started to dig deeper). Any advice is appreciated. This is extremely frustrating since the system is less than 2 months old. Thanx!
