Yesterday I replaced the video card and monitor. Now there's a Radeon Pro WX-2100 video card and an Acer SB-220Q monitor.
The video card has a fixed refresh rater of 60Hz. The monitor accepts a refresh rate up to 75Hz. The monitor's highest resolution is 1920x1080 dpi. I set this resolution in Xfce4-4.12, but yesterday it kept resetting to the old HP LA1952g's 1280x1024 dpi resolution. Logging in this morning and starting X the monitor came up in 1920x1080 dpi resolution. Great! I thought the issue was resolved. But wait ... when I woke the monitor after being away for a half-hour or so, it reverted to 1280x1024 dpi. I've not seen any activity on the xfce mail list since I first posted this issue yesterday. Perhaps someone here has an idea why it won't stay at the set resolution. I also have issues with it not fully blanking when it should suspend or shut off and not being able to change the brightness using the button on the bottom edge. But, one thing at a time and I'll try again to get a chat response from Acer about the brightness issue. Regards, Rich
