Fixed issue with my $18 Mac resolution instead of Apple recommended $160 resolution. I have a mid 2011 Mac Mini and a 37 inch LG ultrawide monitor. I also have a desktop PC and a Surface Pro that is also connected to a monitor. Monitor inputs: DP, 2x HDMI and DVI. Surface Pro is connected to DP and PC is connected to HDMI. Both easily project 2560 x 1080 across the monitor. The Mac Mini never worked when connected via HDMI. It was only 1920 x 1080, which looked like 4:3 on a 16:9 TV. After years of frustration and tracking this issue, I found that the Mac Mini is only limited to 1920 x 1080 when connected to an HDMI port is connected, but supports 2560 x 1080 when connected to an HDMI port B. via a Thunderbolt port with cable MDP>DP. But since the DP port on my monitor was occupied, I figured I'd have to live with the worst HDMI connection on the Mac. Then I found out about Apple's active adapter, which guarantees 2560 x 1080 resolution by converting the Thunderbolt connection to a dual-link D-Port VI - but the adapter costs $100 and the dual-link DVI cable that i need would cost 60$. There was a link to this product on an internet forum about the Mac Mini resolution. I've tried other more expensive MDP (Thunderbolt) to HDMI converters and cables in the past to solve this problem and none of them worked - I didn't even know there were active adapters and passive adapters! For $18, rebooted my computer, and used my existing HDMI cable, this active adapter brought me the 2560 x 1080 glory I've been chasing for the past 4 years, and I couldn't be happier! Terrific!
