The two decisions that matter are panel type and how you connect it. Everything else on a monitor specification sheet is noise at this price.

A monitor is the component you look at most and replace least often. That asymmetry makes it worth getting right, and it also means the cheap decision costs more over time than it saves.
The short answer: decide panel type and connection method first. Those two choices determine whether you will be happy with the monitor in three years. Resolution and refresh rate are secondary at this price.
Decision one: panel type
At under $300 you are choosing between two panel technologies, and the trade-off is real rather than marketing.
IPS gives accurate colour and wide viewing angles. Its weakness is contrast — blacks are dark grey rather than black, which is noticeable in a dim room and in dark scenes.
VA gives far better contrast, so dark content looks properly dark. Its weakness is response time in the darker transitions, which can produce visible smearing in fast motion, and narrower viewing angles.
IPS Black and similar variants sit between the two, raising IPS contrast towards 2000:1 while keeping the colour behaviour. If you can find one in budget, it is the panel most people would choose if they could compare them side by side.
Which one to pick:
Mostly documents, spreadsheets and web work: IPS, because text clarity and viewing angle matter more than contrast
Watching films and playing games in a dim room: VA, because contrast is what your eye notices
Photo or video work: IPS, and check the stated colour coverage rather than trusting a general claim
Decision two: how you connect it
This is where budget monitor purchases go wrong most often, and it is entirely avoidable.
Connection methods and what they carry
Connection
What it carries
Watch out for
HDMI 1.4
4K up to 30Hz
30Hz feels visibly sluggish and is the most common disappointment
HDMI 2.0
4K at 60Hz
Fine for office work, no power delivery
DisplayPort 1.4
4K at 60Hz and above, daisy-chaining
Laptops often lack a DP output
USB-C with DP Alt Mode
Video, power delivery and USB data over one cable
Check the wattage, not just the presence, of power delivery
The USB-C power delivery wattage is the specification to read carefully. A monitor rated at 65W will charge a thin laptop but will not keep a larger one topped up under load, and the battery will still drain slowly during heavy use. 90W or above is the safe figure for a general-purpose laptop.
Scenario picks
Best for a single-cable desk
The Dell UltraSharp U2723QE is the practical choice if you want one cable from laptop to monitor carrying video, power and peripherals. Its relevant characteristics are a 27-inch 4K IPS Black panel, 90W USB-C power delivery, and a built-in USB hub with daisy-chaining.
Monitors & Displays
Dell UltraSharp U2723QE
One cable to a laptop, IPS Black contrast, and full height adjustment. Sixty hertz only, so not a gaming panel — but for office and colour work it removes almost every inconvenience.
The two limitations to accept: 60Hz refresh rate, and 90W power delivery that will not sustain a 16-inch workstation under sustained load.
If that is over budget
Drop the USB-C hub requirement first. A monitor without USB-C but with HDMI 2.0 and DisplayPort 1.4 costs noticeably less, and you can add a separate docking hub for less than the difference. You lose the single-cable convenience but keep the panel quality.
Buy a height-adjustable stand explicitly if you can. Reviews rarely mention it, but a monitor you cannot raise to eye level will have you stacking books within a week.
How to choose
Match the panel to your main task
IPS for text and colour, VA for contrast and dark-room viewing, IPS Black if it fits the budget. This one decision does more than every other specification combined.
Check the pixel density against your viewing distance
Roughly 110 pixels per inch is the threshold where text stops looking soft. For a 27-inch screen that means 4K; for a 24-inch screen, 1440p gets close.
Confirm you can actually drive it
Check your laptop's port specifications for the resolution and refresh rate you are buying. Verify the cable in the box supports it too — some ship with an HDMI 1.4 cable and cap the monitor they came with.
Read the power delivery wattage, not just the presence of USB-C
Sixty-five watts is not enough for a large laptop under load. Look for 90W or above.
Insist on height adjustment
Check the stand's ergonomic range in the specification. If it only tilts, budget for a monitor arm or a riser.
What not to overpay for
High refresh rates for office work, where 60Hz is genuinely enough
HDR badges on panels without local dimming
Curved ultrawides if your desk is under about 120cm wide
Built-in speakers, which are almost universally poor — a $40 desktop pair beats them
4K on a 24-inch monitor if it means downgrading brightness or the stand
The cables in the box
Two things to verify on arrival, because both are common:
The bundled cable may cap the monitor. A 4K60 monitor shipping with an HDMI 1.4 cable cannot reach its own maximum. Check the cable’s specification, and budget for a DisplayPort or USB-C cable if needed.
USB-C cables are not interchangeable. A cable rated for charging only will not carry video. Look for an explicit DisplayPort Alt Mode or Thunderbolt rating.
Get the panel and the cable right and a budget monitor will serve you for years. Get either wrong and no amount of resolution fixes it.
