The monitor in this deal is Samsung’s ViewFinity S6 S65TC, model LS34C650TANXGO. On October 8, 2026, PCWorld reported it at Amazon for $399.99, down from $799.99. That is a 50% discount, and the monitor also works as a Thunderbolt 4 hub that can charge a laptop. Whether the deal is worth it depends on whether you will actually use the dock. If you will, the price is attractive. If you only want a large screen for gaming or color-critical work, the panel limits PCWorld describes matter more than the discount.
Confirm you are looking at the right model
Samsung sells several 34-inch ViewFinity monitors, and the feature set described here belongs to one of them. Before you check out, confirm that the listing shows model number LS34C650TANXGO and the S65TC name. If the model number differs, the Thunderbolt 4 dock, KVM, and 100Hz specifications in this article may not apply to what you are buying.

What the price actually is
Two prices appear in the reporting, and they come from different sources and dates:
| Source | Price | Date and context |
|---|---|---|
| Amazon, as reported by PCWorld | $399.99 | Reported October 8, 2026. PCWorld describes this as 50% off. Stock levels and how long the price lasts are not stated. |

The 50% figure compares Amazon’s reported deal price with Samsung’s listed price. It is not a long-term price history. Amazon prices change without notice, so treat $399.99 as the price on the day it was reported and check the live listing before you buy.

How the Thunderbolt 4 dock works
The dock is the reason this deal is more than a discounted monitor. It replaces part of a desk setup that many people otherwise buy separately.

Connecting and charging a laptop
A single Thunderbolt 4 connection can link a compatible laptop to the monitor and charge it, with up to 90W of power delivery. The 90W figure is a maximum. A laptop that needs more power under load, or a laptop with a charger rated above 90W, may charge more slowly while in use.

Sharing one keyboard and mouse with the built-in KVM
The built-in KVM lets one keyboard and mouse control more than one connected computer. It helps when you move between a work laptop and a desktop, but it does not change what each computer can do. Your setup still needs the cables and inputs each machine requires.

- Warranty: SANSUI 34-inch Curved gaming computer monitor support money-back and free replacement warranty from order date within 30 days and lifetime technical support.
- Good fit: people who work on a Thunderbolt 4 laptop, want one cable for power and peripherals, and want a wide workspace for documents, spreadsheets, or multiple windows.
- Weaker fit: serious gaming, because of the combination of the VA panel, 100Hz refresh rate, and aggressive curve.
- Poor fit: color-critical professional creation, artwork, and CAD, because of the color accuracy PCWorld describes for this panel.
PCWorld’s deals editor, Gabriela Vatu, put the dock point this way: “And if you aren’t going to take advantage of Thunderbolt 4, you’re paying the premium tax for no benefit.” That is a fair test. If your laptop does not have a Thunderbolt 4 port, the dock feature does not help you, and a cheaper 34-inch monitor without it may suit you better.

Use these five checks to compare this model with other 34-inch monitors. The sources do not compare it head-to-head with named competitors, so you need to do that comparison yourself with current listings.
- Dock versus separate dock: Does the monitor’s Thunderbolt connection and laptop charging replace a dock you would otherwise buy?
- Screen specifications: Compare size, resolution, aspect ratio, curvature, and refresh rate.
- Input and peripheral support: Check KVM, port count, and whether you need more than one computer connected.
- Use case fit: Confirm the panel suits gaming or color work if either matters to you.
- Verified current price: Compare live prices on the same day, and include the Samsung list price as a reference.
Based on the evidence available, this monitor is a strong option for a Thunderbolt 4 laptop user who wants a wide, single-cable desk. It is not established to be the best 34-inch monitor overall.
Buying checklist
- Confirm model LS34C650TANXGO on the listing.
- Check that your laptop has a Thunderbolt 4 port and a charger rated within the 90W maximum.
- Count the peripherals you need to connect and confirm the port layout on Samsung’s specification sheet.
- Check the live Amazon price and stock on the day you buy.
- Skip the model if your main use is competitive gaming or color-critical work.
The Bottom Line
At $399.99, the reported Amazon price on October 8, 2026, this Samsung ViewFinity S65TC is a good buy for a Thunderbolt 4 laptop user who wants one cable for charging, peripherals, and a wide screen. If you do not need the dock, the discount does not make up for the panel limits PCWorld describes, and you should compare it with other 34-inch monitors at their current prices.
