It’s about HDMI capability test with DP->HDMI dongle PS175 2. The actual issue is no output for resolutions above 1080P on some specific monitors. 3. But even on these monitors, resolutions include 1080P and below is no problem. 4. These monitors are working fine under windows 10 with same board for any resolutions. 5. as we communicated with original manufacturer of PS175: below 1080p, PS175 is working in level shifter mode; above 1080p, working in converter mode. Below is a list of such monitors: AOC U2870VQE PHILIPS 288P6LJEB/93 SUMSUMG UA48HU5920 Skyworth 55M6 LeEco Letv 50 Air</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
