Below is the maximum resolution
for each web browser on a computer. If you have a PC hooked up
to your TV, you will not get the best picture quality due to
browser limitations. A 720p format has a resolution of 1280×720.
Most entry level TVs these days are 1080p and upscale whatever
image is given, but higher resolution input looks better.
Google Chrome: Up to 720p
Firefox: Up to 720p
Internet Explorer: Up to 1080p
Microsoft Edge: Up to 4K (requires HDCP 2.2 connection to 4K
display, with at least Intel’s 7th gen Core CPU, and Windows 10)
Opera: Up to 720p
Safari: Up to 1080p (requires OS X 10.10.3 or greater)
There are browser
addons available for services, such as Netflix, to up the
resolution to 1080p. Better to get a streaming box, than using a
PC if you want the best quality pictures for your TV.
