Prime Big Deal Days 2024 deals on OLED monitors

Samsung 49-inch ultrawide OLED 240Hz gaming monitor, $1079.99 ($720 off at Amazon)

Corsair 45-inch ultrawide OLED 240Hz gaming monitor, $1199.99 ($800 off at Amazon)

LG 39-inch ultrawide OLED 240Hz gaming monitor, $824.99 ($675 off at Amazon)

Corsair 27-inch QHD OLED 240Hz gaming monitor, $599.99 ($400 off at Amazon)

OLED monitors are the cream of the crop for gamers, and at the moment you can’t get any bigger than Samsung’s 49-inch super-duper-mega-ultrawide. It’s easily the best bang-for your-buck on the list. But for something a little less unwieldy, I’d go with the MSI 34-inch ultrawide and its more manageable 3440×1440 resolution.

If you want to upgrade to OLED for as little cash as possible, Corsair is offering a 27-inch QHD model that’s great for gamers for just $600. That might also be the best choice if you’re interested in competitive gaming — its lower resolution and 240Hz refresh rate is a great compromise if you’re hoping to keep those framerates up.

Prime Big Deal Days 2024 deals on gaming monitors

Samsung 55-inch Ark 4K 165Hz gaming monitor, $1799.99 ($1300 off at Amazon)

Samsung 43-inch 4K 144Hz gaming monitor, $569.99 ($330 off at Amazon)

Acer 27-inch QHD IPS 240Hz gaming monitor, $222.99 ($177 off at Amazon)

Asus 27-inch 1080p 165Hz gaming monitor, $134.00 ($66 off at Amazon)

Gigabyte 34-inch ultrawide 144Hz gaming monitor, $329.99 ($70 off at Amazon)

Once again Samsung offers both the biggest monitor and the biggest discount in the gaming sector, this time on the humungous, curved, and rotatable 4K Ark design. But that one’s beyond most people’s budgets (and their desk’s weight limit). For an easy recommendation I’d once again go with the ever-reliable Gigabyte 34-inch ultrawide, already a good deal at its regular $400 price, a steal at $70 off.

For something more general for a home office, check out that Acer 27-incher. It’s QHD with a speedy 240Hz refresh rate, a cut above the usual, and uses a high-quality IPS panel. That makes it great for both competitive multiplayer gaming and office or media production work.

Prime Big Deal Days 2024 deals on office monitors

Samsung 32-inch 4K Smart Monitor, $229.99 ($130 off at Amazon)

Asus 24-inch 1080p IPS monitor, $84.99 ($30 off at Amazon)

Sceptre 24-inch 1080p monitor, $69.97 ($40 off at Amazon)

Asus 15.6-inch OLED portable monitor, $249.99 ($100 off at Amazon)

MNN 15.6-inch USB-C portable monitor, $64.99 ($25 off at Amazon)

For a general office monitor, I’d recommend Acer’s 27-inch 4K model. It’s got tons of resolution on a high-quality panel, and a USB-C connection for easy laptop support. Samsung’s 32-incher doubles as a smart TV (including streaming apps) if you want to watch an episode on your lunchbreak. For the absolute cheapest deals possible, check out the Sceptre and Asus 24-inch 1080p models.

On the portable side we’ve got two choices: a gorgeous OLED from Asus that’ll look great next to any laptop, or a similar panel from MNN for a fraction of the price. Choose according to your budget.

FAQ
1.
What size of monitor should I buy?

Monitor size depends on personal preference and location. 

A 24-inch monitor is fine for a desk that is around 24 inches deep, or less. Its small size will still be sufficient because the monitor is closer to you.

Most people, however, will want to go with a 27-inch monitor. The added size will make the monitor easy to see. This also opens up a wider range of 4K monitor options, as 4K is very rare on a 24-inch monitor.

Larger monitors, such as a 32-inch widescreen or 34-inch ultrawide, are great for deep desks and people who want an immersive experience. Monitors this large can serve as a TV replacement in a small room. 

Displays of even larger size, such as 42-inch or 48-inch HDTVs, are best for home theater setups or an unusually large office. You’ll want to sit four to six feet away from a display of this size.

2.
What display input is best? (HDMI vs. DisplayPort vs. USB-C)

USB-C is the best display input for most people. It works by bundling DisplayPort into USB-C, so offers all the same features as DisplayPort. Yet it retains the features of USB-C including optional support for Power Delivery to charge external devices. This is why we recommend a USB-C monitor for most people.

DisplayPort is generally second-best. It supports higher resolutions and refresh rates than HDMI. This input is particularly common on desktop computers. 

HDMI comes in third due to lower resolution and refresh rate support. This is improved by HDMI 2.1, but this feature remains hard to find and often adds to a monitor’s price.

All three of the options above handle 1080p at 60Hz, which is the most common resolution and refresh rate available today. It’s also important to buy a monitor that has an input compatible with your PC.

3.
Are all monitors compatible with Windows and MacOS?

Modern monitors are compatible with all recent versions of Windows and MacOS. They’re plug-and-play, which means the monitor should display an image without the need to install driver software or mess with Windows or MacOS settings.
