My work T480 was using build 1803 of Windows 10, with the original 2017 video driver which was working just fine for me. Yesterday it was updated to 1809, which I wasn't able to defer any further. I was worried about the 19x series, but I knew 1809 wasn't completely negatively reviewed here, so I checked out how it was today.
Well it's worse now. Before I had a nice flat stable image on my monitor, no issues at all. They also updated the video driver (and possibly the system bios, but I don't have a record of what the version number was beforehand). The new video driver version is 18.104.22.16872 which is from 2018. Now the image on the monitor doesn't appear as stable anymore, neither does text on it. So this definitely rules out the displayport-to-dvi adapter I have. I will need to give it a chance and see if I get used to it, because I remember when previously I had been moved to 1803 or some other earlier build I noticed the difference and didn't like it but it worked out. This one probably won't tho.
I wish they hadn't updated the video driver, now I don't know how much of the interference is from the OS build and how much is the video driver. A little pissed now, because if I don't get used to it it basically means the laptop is now just a telephone to be used just for meetings on MS Teams and to use Citrix the rest of the time (which isn't as bad as it sounds because the VPN tunnel is capped at 5 megabit but Citrix is not). However because in the past year they also changed Citrix scaling settings text is currently scaled with a blur but is otherwise stable. I can force it to native and make it sharp but it doesn't look like how it did before that server side change.
Given that it's June 2020 and I'm receiving 1809 which is October 2018 a year and a half later from release date, this laptop might never receive build 2004 or later because they tend to replace the hardware every 3 years.
To make it worse, they also monkeyed about with the bios settings as well. I can't go into the boot menu or change some settings (though I am not sure if I could before), there is a password now. I can't fault them too much because it's their property not mine, but I did want to do some testing with different builds and OSes to see how they all appeared on the same hardware and now I can't. 🙁
What I don't understand, and I don't think any of us do either, how is it possible that Microsoft, Intel, Lenovo, etc. with tens of thousands of employees between them, connected to an even vaster number of developers, engineers, etc. never noticed that it isn't as ideal as it might have been previously. Why is it only us that can see it? 🙁
