Weme via Amazon offers its Weme Mini DisplayPort to HDMI Adapter in Black, model no. LYSB00NN20SZE, for $7.99. Coupon code "TNTX8JO4" cuts that to $4.39. Plus, Prime members bag free shipping. (Non-members can spend $35 or more to qualify for free shipping; otherwise, shipping costs $8.) That's $4 off and tied with our January mention of another color as the lowest total price we've seen. It's compatible with Thunderbolt 2 ports and supports video resolutions up to 1920x1200 and 1920x1080 (1080p).
