Black Friday isn’t until Nov. 27, but Amazon is already offering some substantial discounts on OLED gaming monitors from LG, Samsung, and ASUS, with savings ranging from $100 to nearly $580. And since OLED monitors generally offer near-instantaneous pixel response times, excellent contrast, and deep blacks, they’re particularly appealing for games with fast movement or darker environments. The most affordable option is Samsung’s 27-inch Odyssey OLED G6 at $409.99, while the biggest dollar discount goes to LG’s 45-inch Ultragear at $1,121, down from $1,699.99.

These LG Ultragears are up to 41% off

The 32-inch LG UltraGear 32GX870A-B is down to $819.99 from $1,399.99, saving you nearly $580 on a monitor that works well for both visually demanding games and competitive shooters. Its biggest advantage is LG’s Dual Mode feature, which lets you switch between sharp 4K resolution at 240Hz and 1080p at 480Hz when faster gameplay takes priority. That makes it particularly versatile if you enjoy cinematic single-player games but also spend time playing competitive titles. That said, you’ll need a powerful gaming PC to take full advantage of its higher refresh rates, particularly at 4K.

The 27-inch LG UltraGear 27GX790B-B is down to $649 from $999.99, a $350 discount that brings it to its lowest price ever, according to price trackers. It’s built for speed, with a 1440p OLED panel that runs at 540Hz and a Dual Mode that pushes the refresh rate to 720Hz at 720p—making it particularly appealing for competitive games like Counter-Strike 2 or Valorant, where smooth motion and quick reactions are essential. Just keep in mind that you’ll need a powerful PC capable of delivering exceptionally high frame rates to take full advantage of those refresh rates.

The 45-inch LG UltraGear 45GX900A-B is down to $1,121 from $1,699.99. Its expansive 800R curved OLED display uses a 21:9 aspect ratio and 3440 x 1440 resolution, giving you a wider field of view that’s particularly enjoyable for racing games, flight simulators, and cinematic adventures. You also get a 240Hz refresh rate, 0.03ms response time, and support for G-Sync and FreeSync Premium Pro.

Other OLED gaming monitors discounted for Black Friday

The 27-inch Samsung Odyssey OLED G6 (G61SH) is down to $409.99 from $599.99, making it the most affordable OLED monitor in this roundup. Despite the lower price, you’re still getting a 1440p OLED panel with a 240Hz refresh rate and 0.03ms response time, which is more than enough for smooth gameplay in most modern titles.

The 27-inch Asus ROG Strix XG27ACDNG is a QD-OLED gaming monitor designed for fast-paced action, and it is currently down to $549 from $759. Its 1440p resolution and 360Hz refresh rate offer a good balance between sharp visuals and responsive gameplay, while the 0.03ms response time helps keep fast-moving objects clear. At this price, it’s the more affordable alternative to the faster LG 27GX790B-B if you don’t need refresh rates beyond 360Hz.

The 34-inch Alienware AW3425DW is down to $699.99 from $799.99, saving you $100 on a curved QD-OLED gaming monitor. Its 3440 x 1440 resolution and 21:9 aspect ratio give you more horizontal screen space for immersive games like racing simulators and open-world adventures, while the 240Hz refresh rate and 0.03ms response time help keep fast-moving action smooth and responsive. You also get FreeSync Premium Pro and G-Sync compatibility to help prevent screen tearing.

Black Friday FAQs

Does Amazon have Black Friday deals?

Yes, Amazon has Black Friday sales, but prices aren’t always what they seem. Use a price tracker to make sure you’re getting the best deal, or refer to guides like our live blog that use price trackers for you. And if you have an Amazon Prime membership, make the most of it.

What stores have the best sales on Black Friday?

Nowadays, both large retailers and small businesses compete for Black Friday shoppers, so you can expect practically every store to run sales through Monday, Nov. 30, 2026. The “best” sales depend on your needs, but in general, the biggest discounts tend to come from larger retailers who can afford lower prices: think places like Amazon, Walmart, Target, Best Buy, and Home Depot. You can find all the best sales from major retailers on our Black Friday coverage.

Should I wait until Cyber Monday to shop online?

No. If you find the product you’re looking for with a major discount right now, get it. It’s not likely to drop any lower, but it could always run out of stock. Take advantage of price matching or guarantees instead of waiting. Remember, you can always return products later if you change your mind. For the majority of products, the deal from Black Friday will be the same one on Cyber Monday.

The Apple Silicon iMac got its fourth refresh this month.

Every other Apple Silicon Mac has found a way to move forward over the last half-decade—we’ve gotten a more Pro design for the MacBook Pro, a mini-er design for the Mac mini, and a Mac Studio that has finally made Apple admit it doesn’t want to make the Mac Pro anymore.

But the Apple Silicon iMac has always been more interested in looking backward. It’s the thin, screen-on-a-stand iMac design by way of the original Bondi Blue G3 iMac. It’s a clean and pretty desktop computer, one I see all the time in small offices and on TV shows that depict small offices. We’re long past the days when it was Apple’s primary workstation computer.

Tim Peters, one of Python’s earliest and most influential contributors, died on July 15 at age 74. Known as Python’s second real user, Peters created the Zen of Python and Timsort sorting algorithm while contributing to numerous core components. He also served as a Python Software Foundation director from 2001 to 2014. Adafruit remembers Peters in a blog post: He’s best known for the Zen of Python, PEP 20, still printed by typing import this. In 2002, he gave Python Timsort, the sorting algorithm he designed for lists, later adopted by Java and Android. He also polished the cyclic garbage collector and the pymalloc allocator, worked on the dict implementation, the float object, the math module and Karatsuba multiplication in longobject, and wrote the first version of doctest, plus difflib, pickletools and tabnanny.

He was a director of the Python Software Foundation from 2001 to 2014. Before Python, he wrote compilers at Cray Research and speech-to-text software at Dragon Systems. The thread is full of recollections from core developers about his patient, detailed answers on the mailing lists, signed with his trademark . Python creator Guido van Rossum also paid tribute to Peters in a post on discuss.python.org, writing: “It’s hard to overestimate Tim’s influence on Python. He’s probably best known for writing the Zen of Python (PEP 20), but to me he was a mentor and language co-designer long before that…”

“ScienceAlert is reporting that researchers may have finally determined why, for many years, power grids around the world have been pulsing every 60 seconds,” writes longtime Slashdot reader fahrbot-bot. The likely culprit? Uninterruptible power supplies running routine battery checks. From the report: Every minute, some uninterruptible power supplies perform routine battery checks, creating small but measurable surges in electricity demand. And it’s like clockwork. “Even benign control routines can become systemically relevant when many devices act coherently,” writes a team led by physicist Dirk Witthaut of the University of Cologne, Germany, in a paper published in Nature Energy. “Unintended synchronization can generate recurrent and potentially amplified oscillatory behavior in large-scale cyber-physical energy systems.”

To figure it out, Witthaut and his colleagues analyzed high-resolution electricity measurements from buildings at the Forschungszentrum Julich research campus in Germany. [… they found that] the 60-second pattern appeared in four buildings, all of which contained uninterruptible power supplies. None of the buildings they measured without these systems showed the same pattern. Following the electrical signals more closely, the researchers detected tiny bursts of current from the batteries at precisely one-minute intervals. They were able to trace the resulting fluctuations through one building’s electrical system, all the way to the connection with the public high-voltage grid.

The manufacturer subsequently confirmed the culprit’s identity — routine battery self-tests, conducted automatically by the systems’ management software. But why would equipment in different buildings, let alone different countries, be doing this at the same time? The answer appears to lie in the clocks. Digital devices can synchronize their internal clocks using external time signals, meaning that independently operating systems can end up performing their scheduled tasks together. Individually, these small checks are insignificant. But when enough devices act in synchrony, their combined electricity demand can produce a measurable effect across an entire power grid.
