A video of the failure is even better! Attach to the post or provide the YouTube link. Please provide steps to replicate the issue. These steps are very crucial to finding the root cause and fix.Ī screenshot to illustrate the issue is a huge plus. Single display, clone, or extended ( see note2 below).ĭisplay resolution & refresh rate setting of each display ( see note2 below).ĪC or DC mode, i.e. SW or Apps version used to replicate the issue. Ie: Cables&brand, cable type, dock, dongles/adapters, etcĬables Used (I’ve tried both 6 and 10ft lengths): Provide any other hardware needed to replicate the issue. LFP = Local Flat Panel (Laptop panel) EFP = External Flat Panel (Monitor you plug in) Make and model of any Displays that are used to see the issue (see note2 below). I have double checked my system information and confirmed that the BIOS mode is UEFI (screenshot attached). Trying different non-native resolutions does not appear to help the issue.ĭespite my SSU_Ouput saying that my machine is running in “Legacy Mode”. My system has a new Seasonic Vertex (atx 3.0) 1000W power supply, so power should not be an issue for the system.
I have rolled back drivers without success and now I am back on 4146 with a clean install and a fresh install of Windows 11, 1. I have also tried other DP cables without luck. I have reseated the card and reattached the power cables and DP cables. If the machine is running, I can sometimes unplug/replug the DP into the card and it will work - but again, it is inconsistent and most of the time will not work. Prior to installing the A770, I had an RX570 that handled all three monitors without issue (same cables and setup). The monitors are recognized by the System -> Display, but instead of being in the proper orientation, I just get a small square where I am sometimes successful at having “Extend the Desktop to this Display” engage the monitor and work properly (I mocked up an image for you to see what it looks like vs how it is supposed to be: attached).Īfter several reboot attempts, I will get lucky and all 3 monitors will be recognized, but it is not consistent. Only the Phillips monitors that seem to be affected. The monitors are 1x Dell UW and 2x Phillips 4k (4k monitors are scaled at 150%). All 3 monitors are directly connected to A770 via DP to DP. This is an intermittent issue, where 1 or 2 of my 3 monitors will not show the desktop upon booting windows. Provide a detailed description of the issue
