Of course, this isn't an inherent property of high-resolution panels. It's caused by idiots in management that "insist" that these TVs have worthless image filtering algorithms that distort the picture and lag the image.
That, and I've also tested several TVs with "gaming mode" where it doesn't help input lag at all.
Assuming PayPal's currency values are stored in cents, dividing that by 100 results in $92,233,720,368,547,758.07. Looks like a 64-bit signed integer overflowed (or in this case, underflowed), resulting in integer wraparound.
Just Scan (1:1 Pixel Matching): HDMI: 1080p/1080i/720p, Component: 1080p/1080i/720p, RF: 1080i/720
If I'm reading this correctly, the TV doesn't actually support anything higher than a 1920x1080 ("1080p") signal input. So while it might in fact have a 3840x2160 panel, that panel is absolutely worthless, since it has to upscale everything that's being displayed.
Besides that point, most of these so-called "apps" are worthless. I remember a time when Apple fans used to proudly proclaim that even though there was less software on the Mac platform, they were higher quality than Windows programs. Now that the iPhone has hundreds of thousands of apps, quality doesn't matter anymore.
At least Firefox hasn't gone full Windows 8 and reduced everything to 16 colors (yet)...
