On Roon remote, PC Win 7 (64) special characters disappeared on the screen. All icons, small print are not visible, some graphics are also distorted. Video drivers and OS up to date. Complete removal of Roon and reinstallation does not help.
Since official support for your chosen OS endee from the manufacturers years ago, i think itβs hardly appropriate to claim they βare up to dateβ?
OS has nothing to do with it. Everything worked fine in Roon. And it broke the correct display of graphics, after the latest Roon updates, the OS itself works flawlessly.
Instead of video card manufacturers, get the driver from video chip manufacturer, i.e. nVidia / AMD / Intel as appropriate. Uninstall your old video driver, reboot, then install the new one.
In the unlikely event youβre not able to obtain a newer driver, do the uninstall / reboot / reinstall anyway.
A likely cause for the problem you see is that your driver is corrupted by Windows update.
Thank you @wklie Peter! Your advice as always helps, and the help is very fast !
The driver not compatible with Roon was automatically installed. On your advice, downloaded and installed manually from the AMD website, now everything is fine!
