If you want to get a monitor with HDMI input, then the first thing to ask yourself is "how much money do I have?" Cheap monitors tend to be TN panels (the cheapest kind) and good monitors cost more. Also, if you really care about color accuracy, then paying for an IPS panel would be worth it. If not so much, then go with a VA panel (they're somewhere in between). As long as you don't want 120Hz or faster refresh rate or anything like that, most people will be fine on any decent monitor.
There are two factors to consider when you're choosing a monitor: the size of the screen, and the size of the monitor. The first is important because it's how big your content will be displayed. The second is unimportant because most monitors will fit any space where they're placed. However, if you choose a small monitor with a large screen, then it will look weirdly disproportionate. If you choose a large monitor with a small screen, then your computer could end up looking like an old TV set from 1998!
Aspect ratio is the ratio of the width to the height of your screen. A common aspect ratio for monitors is 16:9, but some monitors have a 16:10 aspect ratio.
16:9 displays are standard in most (but not all) cases. They're a bit wider than they are tall, which you can tell by looking at a computer monitor or TV and comparing the width with its height (you'll see that it's wider). This may make some things look stretched out on your screen (like text), but it's great for watching movies and TV shows since most movies are filmed in this format. Most computers come with this aspect ratio built into them as well—you can't change it unless you buy an expensive graphics card or external monitor that allows you to adjust this setting manually.
16:10 displays are slightly longer than they are wide; their height is about 10 percent greater than their width (which means everything looks squished up). This makes them better suited for working on spreadsheets or other documents where more horizontal space is needed (like spreadsheets) because there isn't as much wasted space around the edges of your screen when using these kinds of applications!"
This is the most common resolution of monitors you'll see, especially if you're looking for something that can handle gaming. If you have an Xbox One or PlayStation 4 and want to use it as your primary display, 1080p is usually a good choice. It's also fine at 60Hz. 1920x1200
This resolution has more vertical space than 1920x1080 but not quite as much horizontal space—it's basically 1.5 times bigger than 1080p in each direction, though that's not exactly how it works out numerically because every pixel has been divided into smaller sub-pixels by the panel manufacturer. The extra height means that more information can be fit onto your screen at once without resorting to scrolling; this makes games look more immersive while making it easier to spot enemies lurking off-screen. 1920x1440 This resolution provides roughly 70% more horizontal width than standard 1080p displays—this gives you four times as many pixels on either side of your field of view when playing first person shooters or racing games where peripheral vision matters most! 2560x1440 (1440p)
This wider aspect ratio provides about 80% more vertical height than standard 1080p displays—this gives you four times as many pixels above and below your field of view when playing first person shooters or racing games where peripheral vision matters most! 3840x2160 (4K/UHD)
With 3840 x 2160 resolutions available there’s no reason why anyone would ever need anything less again…
The contrast ratio is the difference between the darkest color your monitor can display and the lightest. The higher this number, the better: it means that you'll be able to see more detail in shadows and highlights. Contrast ratio is a key factor when choosing a monitor—it impacts both picture quality and pricing. Remember that contrast ratio is not brightness; rather, it represents how much of a difference there is between black and white on screen.
Brightness is important because the higher the brightness, the better your picture quality. It is measured in cd/m2, with a higher number indicating better brightness. The drawback of a high-brightness monitor is that it makes your eyes tired over time if you use it for too long.
A good rule of thumb to follow when shopping for monitors is that you should look for one with at least 250 cd/m2 (for example, 300 cd/m2).
The response time of a monitor is the amount of time it takes for pixels to change from one color to another. The lower the number, the better.
Refresh rate is the number of times per second that your monitor's image is refreshed. It's measured in hertz, or Hz, and there are two standard refresh rates: 60Hz and 120Hz.
60Hz is the standard refresh rate for consumer monitors, while 120Hz and 240Hz are used for high-end gaming monitors.
There are three primary panel types, TN, IPS and VA. TN is the most common type with high refresh rates and very fast response times (1ms). If you’re looking for a monitor for gaming then this is the way to go. IPS has better color reproduction but does not have as high of refresh rates or response times as TN panels do (5ms). You can tell if your monitor is an IPS if it has 178 degree viewing angles and uses LED backlighting instead of CCFL backlighting. VA panels sit between TN and IPS in terms of price point, quality, color reproduction and viewing angles but they usually have slower refresh rates than both IPS and TN monitors which makes them less ideal when gaming on them since their response times tend to be higher than other panel types.
If you're looking for a cheap monitor with an HDMI connection, you can get it. For example, the HP Pavilion 24-f003 is a 24" LED 1080p monitor that has HDMI input and output ports. It's not the greatest of monitors, but it does the job for most people who want to connect their laptop or desktop to a monitor. Plus, at $100 (as of this writing), it's much cheaper than other options out there!
To sum up, you can get a cheap monitor with an hdmi connection. The only thing you should consider is the panel type and resolution of your monitor. If you want to use IPS or VA, then the answer to the next question is "Pay more".
