If you prioritize overall picture quality and gaming performance and don't mind paying more, the LG G3 could be a great choice. It also offers better brightness in both dark and bright rooms, making it versatile for various lighting conditions. On the other hand, the Sony A80K is less expensive while offering excellent sports viewing and sound quality. It has a high-quality motion processing feature but falls short in bright room performance. This TV is ideal if you're looking for a high-quality experience without the higher price tag of the LG. Both have similar support for HDR formats and use as a monitor, ensuring great overall performance. Give Feedback

"It’s a high-end TV through and through something that becomes clear the moment you glance at its stunning picture. The A80K’s surgically precise contrast control is likely the first thing you’ll notice about its picture ... every piece of content looks better when this amount of precision is available. Color accuracy is another strong suit; the A80K features fantastic out-of-the-box color accuracy in the Custom picture mode."
