I am suspecting that this Samsung monitor is expecting something different in it's UHD deep color mode, coz I am not able to reproduce this issue with any of the UHD/HDR monitors available with me (LG, Philips). Unfortunately, this issue can't be worked upon without this particular monitor. - Shashank</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
