How to replicate the problem: use 720P output resolution

I have noticed the odd resolution related quirks that I have not seemed to be able to find a direct answer for. I have my Pie3 plugged into a Sony HDTV that supports 1080P. With the RaspberryPie set to 'default' it outputs 1080P and everything works 'OK'. The games do not require this resolution though and when I was messing around with getting Netflix to work on the Pie I found that Netflix only supports 720P through Chrome(ium) and if the Pie was outputting 1080P the frame rate was terrible. Setting the Pie to output 720P let Chrome(ium) play Netflix fine with 720P resolution (which was OK, but not as good as 1080P through my XBox360).

With the 720P output the text menus are much more readable on a large screen but all the ES themes I have tried seem to have graphics that did not scale properly to 720P and they went off the top/bottom of the screen a bit. Playing with the overscan setting has NO effect on the ES interface, only the console was affected which if you look in config.txt it seems to indicate that the overscan setting only affects the console.

From what I have been able to gather from different posts it would seem that the theme graphics are sized to fit a particular screen resolution. If the screen resolution is different then they likely won't fit properly. It seems that graphics 'sized' for 720P will upscale to 1080P but not the other way around. I would love to know if this is correct or not.

Thanks for any help :)

you need to set overscan_scale = 1 to additionally affect the framebuffer (emulationstation/games).

Thanks! There was not an entry (commented or otherwise) in config.txt and I did not come across that in my generic searches for RaspberryPie info. Will have wait until I get home this evening to check on the effects. The best I could do from work is make the changes via Putty.

Thanks again. I was able to adjust the overscan and got the screen displaying properly on 720P.
