The LG G5 OLED outperforms the Hisense A6 Series 4K 43 across picture quality metrics with perfect blacks and 120Hz gaming support as noted in RTINGS and CNET evaluations. The Hisense provides basic 4K LED performance at a lower cost but lacks the contrast and motion clarity of the LG G5. LG G5 wins for premium viewing while Hisense suits only the tightest budgets.
