A:AnswerJoe - I don't know the dimensions of your GMC Acadia, but the size of the box for the 75" Q60A is 72.2 x 43.7 x 7.5 (W x H x D in inches). Please note that it is highly recommended to transport TVs upright. ^Gina
A:AnswerLayne - Thank you for your question. With HDMI 2.1 being such a complex topic, we feel it is clearer to highlight the specific features supported by each TV model. This model has 3 HDMI ports, all of which support HDR10+ and Auto Low Latency Mode (Auto Game Mode). The “HDMI In 2” port further supports eARC. If you are looking for a TV capable of 4K@120fps (FRL), please consider a step up to Q70A Series, which supports “FRL on HDMI In 4”. ^Gina
A:AnswerHi Ralph - If the TV stand you are referring to does not support the weight of TVs up to 75", we do not recommend using it with a 75" TV. ^Gina
