How can you tell if the Black Friday monitor really dropped in price?
Compare today’s price with the history of the last month.

How the fake discount works
The "before" price is whatever the store says it was.
Three common ways a monitor can look cheaper than it is: the price goes up in the days before Black Friday and returns to normal with a "discount" label; the crossed-out "was" price is a value the monitor never really had; and the ad compares one version with another of the same name, like the 60 Hz with the 144 Hz, the Full HD with the QHD, or one size with another. None of them shows up if you only look at the store page on the day.
What takes all three apart is the price history: the price of the same monitor, the same model and the same seller, day after day.

Step 3 of 7
The Radar’s yardstick: the 30-day median
Today’s price against the middle price of the last month.
The Radar records the price of each monitor every day. To decide whether a drop is real, it compares today’s price with the median of the last 30 days from its own price history, from the same seller. The median is the middle value, so a price spike the day before doesn’t pull it up. The math:
drop = (30-day median minus today’s price) divided by the 30-day median
Only what stays below of that median is called a discount. The store’s crossed-out price doesn’t enter the math. A change of seller doesn’t count as a drop either, because it’s a different price, from a different place.
Step 4 of 7
If the history is still short
With no history, the Radar doesn’t call it a discount.
To confirm a discount, the monitor needs at least 14 days of its own history on the Radar. Before that, the page shows today’s price and a note that the 30-day median is still being built, without the word "discount". The same goes for the "find" label and for the list of monitors that dropped in price. The Radar of Monitors started recording prices on 09/10/2026, so near Black Friday 27/11/2026 many models will have a short history.
This means the discount list may be shorter than the list of advertised deals. That’s on purpose: we’d rather show a little that’s true than a lot that’s doubtful.
Step 5 of 7
Watch out for the monitor model
Different size, Hz, resolution and colour change the price.
The same line name is often sold in different models, at different prices: size (23.8″ or 27″), resolution (Full HD or QHD), refresh rate (75 Hz or 165 Hz) and panel. A "discount" that compares the price of one model with another isn’t a discount. The Radar shows the type, size, resolution and Hz of each monitor next to the price, and the page lists the panel and ports.
Before buying, check in the specs: the model number, the size, the resolution, the Hz and the panel. If any of them differs from what you saw before, it’s a different product. To choose the type and size, see which monitor to buy.
Step 6 of 7
Five steps to check a monitor
You can do it in two minutes.
- Find the monitor’s page. Each model has its own, with the price chart and the verdict of the day.
- Look at the chart line, not the store’s badge. Is today’s price below the line of the last 30 days?
- Confirm the full model. The model number, size, resolution and Hz count: two versions with the same name are different products, with different prices.
- Check the seller. A price from an unknown seller isn’t worth comparing; the Radar only uses trusted sellers.
- See the final price at the store. Shipping, delivery time and terms change the math, and the final price is the one at the store.

Where to see the monitors that dropped
Three Radar pages, all dated.
| Page | What it shows |
|---|---|
| Real discount | Monitors with today’s price below the 30-day median |
| Black Friday monitors | The same calculation, with the monitors grouped by brand, price range and type |
| Monitors that dropped in price | The biggest drops of the week and the month |
Each list shows the collection date and hides anything that doesn’t have enough history yet.
How we read the discount
- 402monitors in the catalog
- 06/11price date
The Radar compares today’s price with the median of the last 30 days of its own history, from the same seller, and only calls it a discount if it falls below it. With less than 14 days of history, the monitor appears without the word "discount". Black Friday 2026 is on 27/11/2026. Catalog of 06/11/2026: 402 monitors, median price of £170.00.
| Rule | Value |
|---|---|
| History used as the yardstick | 30-day median, from the same seller |
| Minimum history to confirm | 14 days of its own history |
| What doesn’t count as a drop | change of seller and the store’s crossed-out price |

Frequently asked questions
Is it worth waiting for Black Friday to buy a monitor?
Not always. Compare today’s price with the median of the last 30 days for the monitor you want: if it’s already below, waiting may not pay off. The Radar keeps this history every day and doesn’t promise that no lower price exists elsewhere.
How can you tell if a monitor discount is real?
Compare today’s price with the median of the last 30 days from the same seller. Only what falls below it is a discount. The store’s crossed-out "was" price doesn’t count. On the Radar, the monitor’s page shows the chart of this history.
Why doesn’t the Radar show a discount on some monitors?
Because there isn’t enough history yet: the Radar only confirms a discount with at least 14 days of its own history. Before that, the page shows today’s price and a note that the median is still being built, and the discount list doesn’t include it.
Does the monitor price really go up before Black Friday?
In some cases, yes, and that’s why the Radar compares against the median of the whole month and not the price the day before. A spike of a few days doesn’t change the median, and a drop that just returns to the normal price doesn’t show up as a discount.
Does the Radar promise the price is the lowest on the market?
No. The price is the lowest from a trusted seller that we collected on the date, and the final price is the one at the store. The Radar shows whether the price is below its own history; it doesn’t promise that no lower price exists elsewhere.
How do I read the chart?
Each dot is a new monitor. The further right, the more expensive; the higher up, the better the spec sheet score. The price uses a logarithmic scale: each step is worth more dollars than the one before, so the cheaper ones don’t get bunched together. The line connects the monitors that no other, among those filtered, beats on both score and price at once. Compare monitors of the same size: pick the inch range in the top bar.
Where does the score come from?
From the monitor’s spec sheet, with public weights (image, smoothness, connections, ergonomics and recency). The score compares within the type: the Hz of an office monitor are measured against the office yardstick, those of a gaming monitor against the gaming one. It shows what the spec sheet states, not the calibration or the measured brightness. Size doesn’t count toward the score. The full calculation is in How we calculate the score.
Why do some monitors appear without a score?
Because the store’s spec sheet doesn’t give enough information: we need at least three components of the score. We’d rather leave a monitor without a score than make one up. Those monitors stay off the chart and remain in the table, with the price and the button to compare stores.
How many inches do I need?
For a work desk, 24″ at Full HD and 27″ at QHD are the sizes where text looks sharp without scaling up. At 27″ Full HD the density drops to 82 pixels per inch and the text looks less defined; 32″ calls for QHD or 4K. Each monitor’s page shows the pixel density calculated by the Radar.
Is the price on the chart what I’ll pay?
This is the lowest price from Amazon.com, a direct store, the manufacturer’s official store or a seller rated 4.0 with 100 or more sales, usually paying upfront, on the date we checked. It changes without notice, and the colour can change the price. The buy button goes straight to the store, where the price of the day applies.

Where the numbers come from
The rule is the 30-day median of the Radar’s price history, from the same seller, with a minimum of 14 days of its own history to confirm (RADARDEMONITORES.blackFriday.regua). Black Friday 2026 falls on 27/11/2026 (blackFriday.temporada). Its own history began on 09/10/2026. The day’s catalog comes from the check on 06/11/2026.
The guide helps you decide and doesn’t recommend a monitor for you: the final price is the one at the store, and the spec score doesn’t measure the real calibration or durability.
