This is the number of pixels per side of the screen, the greater the resolution the more detailed the image. Alongside this, there are a series of industry standard resolutions that are ideal to stick to except in specific standards.
This is the time it takes for an individual pixel to go from unlit, to lit, and back. This is rarely an issue except in high performance screen with a high refresh rate that exceeds the individual pixels ability to switch color, leading to an effect called ghosting where a slight after image blurs the screen.

Minor difference but it is worth being aware that most televisions do not come with an anti-glare coating for this reason.
Monitor mounting points can vary widely, from static, to freely adjustable, tabletop, to wall mounted. While there is some variation in quality largely the most important aspect here is what fits in your space.
Most monitors these days are wired, and new ones often use the most modern connectors. Avoid getting older monitors with older connectors if you can, this can cause you compatibility issues in the future and the modern connections are direct improvements.
