Hi,



I have just bought Endless Legend on Steam and installed it on my Mac (yosemite up to date).

I play on a Macbook pro 15' (end 2013 with Nvidia 750M), connected to a Dell S2440L monitor (1920x1080 native resolution).



- Before I begin let me say the HDMI output of this generation of Macbook Pros has lots of problems (unrecognised by apple as they usually do), meaning interference leading to random flickering or 2-3 second black screens. To solve this I use a Thunderbolt to VGA adaptor and so use a VGA cable to my monitor. -



After installing Endless Legend from Steam on Mac, I tried to launch the game and change the resolution to 1920x1080 as was proposed in the display options.

The result was a fullscreen game with two black bars on the left and right of the screen oddly uncentered. This baffled me as I tried to play with the xml config file to force the 1920x1080 resolution to be properly applied ... To no effect.



After quite a bit of internet googling and hair pulling, I decided to plug my monitor with a HDMI cable to the laptop.

I launched the game and ... the 1920x 1080 resolution was properly applied through HDMI ! No more black bars on left and right.

Sadly I still had the hardware Macbook Pro electrical interferences which disturbed the monitor and produced flickering and short black screens.





Remembering that end user computer stuff was something all but logical, I then plugged back in the VGA-Thunderbolt adapter. After a bit of tantrum from the monitor about resolution etc lasting about a minute, the monitor switched back to the HDMI output.

I then switched back to the VGA output (the display option for multiple monitor is set on mirroring) and ... the game was working in proper fullscreen 1920x1080 resolution through the VGA output !

I should add here I noticed a difference in the displays preference panel when both HDMI and VGA are connected : the custom resolution are not listed anymore as "1920x1080" (VGA alone) but as 1080p.



My guess is something is amiss in the way the game handles all this resolution business in OS X (1080p vs 1920x1080 in the display preference panel) ... it's a random guess though.



Maybe this will help some people so I hereby post my experience, frustration and solving of the problem here.

Happy new year to those who read this all the way.



Ricus



ps : funnily enough, when unplugging the hdmi cable and restitching to full screen using the VGA cable, the game is once again in its weird fullscreen mode with black bars. Well, if a dev wants some more tests about that, do tell.
