Is there any word on a fix for the overscan issues experienced by me and a few other users here?

In Android build, can not adjust screen size to adjust for over screen issue cause by new HDMi driver. The issue has been reported and will be fixed in two weeks time. The upcoming release. mostly on this week will not able to fix this issue, and the next build will.

Looks like we're a bit past two weeks, so hopefully there's an update very shortly?

Yes, this issue has been dragged longer than I expected. I will meet up with Android team on Tuesday and asking for explanation. The current reason is due to Allwinner improved the HDMI driver for p60 display and causing this issue, and wait for Allwinner fixed. This issue has affected both Android and Remix build. I will try to get an answer on this week.

In general, most HDTV or monitor able to adjust in their setup menu. For Android build, our internal committed date is May 6, 2016.

have any of you tried setting things to a lower resolution such as 1280x720 if not I will post how to do it for debian/ubuntu and oyu can adapt it for arch if that's your distro of choice use pacman Wink

sudo apt-get install fbset
sudo service lightdm stop (or whatever login manager you have)
sudo fbset -a -xres 1280 -yres 720 -vxres 1280 -vyres 720
sudo service lightdm start

Test that mode (Linux of Course) and let me know if there is an overscan issue occuring at that resolution Wink
If you like my work be sure to check out my site or wish to donate to the cause

I have tried the above commands, but they don't help enough. I am using a Dell 2408WFP monitor at 1920 x 1080. This is a widescreen monitor, will Full HD resolution.

The fbset application installs OK any can be used to change the frame buffer size.
Stopping the lightdm service makes my screen go black (no GUI / Window Manager). I need to reset the PINE before I can do anything else.
Using the above fbset command split my screen into two parts, the the RHS being a duplicate of the LHS. There were two mouse cursors! I think this was caused by the -vxres and -vyres parameters (or possibly -a). Using -xres and -yres on their own seemed to work OK.
Using the command fbset -xres 1280 brought the desktop items back onto the screen (shifting the left edge of the screen to it's proper place). However, the fond size became as little larger, as the screen resolution decreased. I tried to use the -yes option to get the taskbar to appear correctly, but even with -yres 300 the taskbar was still partially off the top of the screen and there was nothing at the bottom of the screen.

Hope this helps.
