I want to use an A10 -7860K on an ASUS A88XM-plus Motherboard as a HTPC.
But I have a significant black bars left and right of he picture. Display is an Optoma Projector with 1280x800 native resolution connected via HDMI. I want to use 1280x720 as this is still very common among german TV-stations.
Between some restarts when installing "non-whql-win10-64bit-radeon-software-crimson-relive-17.4.2-apr11" it was there. Full picture, unscaled every pixel 1:1. So, the hardware is capable of doing this. A few reboots later the image is scaled again.
There are just very few places where I can do settings which seem to do anything regarding scaling.
GPU-scaling is off. Scaling mode is set to "full panel" and I have also tried "center" and "preserve aspect ratio". There is no difference between "center" and "full panel" and none of these setting is generating a picture covering the full panel.
