34-inch VA · UK specification · Samsung part LS34C650TAUXXU
A 34-inch VA monitor with a 3440 × 1440 panel and a listed 100 Hz native-resolution mode. Its specified depth with stand is 241 mm.

Specifications checked 10 Sept 2026Manufacturer specifications, not a hands-on test.
The 3440 × 1440 panel supports a listed 100 Hz native-resolution mode. Check the input-specific conditions alongside the figures.
A listed charging output reaches 90 W on the specified USB-C or Thunderbolt port. Match the laptop and cable to that port’s power and display capabilities.
The 90 W charging ceiling may not replace the original charger for a laptop that needs more power. The rating applies only to the stated port.
Allow for the 241 mm listed depth with the supplied stand, plus cable clearance. Check desk depth before choosing this size.

42 specifications in 9 groups. Values are manufacturer specifications unless a row says “Measured result” or “Calculated from cited specifications”. 1 row repeats a listed fact in the manufacturer’s own wording, kept under “Manufacturer wording”.
Manufacturer screen-size class, which can be rounded compared with the active panel diagonal.
SourceManufacturer resolution notation: UWQHD (3,440 x 1,440). See the separate refresh-mode conditions for any lower-resolution configurations.
SourceManufacturer panel designation; technology alone does not establish tested image quality.
SourceManufacturer-listed configuration: Max 100Hz. The comparison uses the native-resolution mode; any higher rate at a lower resolution remains a separate mode. Source, input and cable limits still apply.
SourceManufacturer response-time claim; settings and transition method matter. GtG and MPRT values are different measures and are not independent motion-clarity results.
SourceThe same facts in the manufacturer’s combined or original wording, each with its source.
Manufacturer-listed configuration: Max 100Hz. The comparison uses the native-resolution mode; any higher rate at a lower resolution remains a separate mode. Source, input and cable limits still apply.
SourceManufacturer typical brightness. Not an independent measurement; calibration, mode and content affect output.
SourceManufacturer colour specification under its stated colour space and measurement basis. Coverage and gamut volume are not interchangeable, and this is not an independent colour-accuracy measurement.
SourceManufacturer-listed HDR formats or certification. This alone does not establish real-scene HDR quality, local dimming or measured peak brightness.
SourceManufacturer colour specification under its stated colour space and measurement basis. Coverage and gamut volume are not interchangeable, and this is not an independent colour-accuracy measurement.
SourceThe listed connections include USB-C or Thunderbolt. Video, data, upstream/downstream roles and charging power depend on the particular port.
SourceManufacturer port counts and versions. Confirm source-device support, cable bandwidth and the exact mode; a connector name alone does not guarantee every advertised configuration.
SourceUSB-C: None; Thunderbolt upstream: 90W. Each power rating applies to the specified port; the connected device and cable must support it.
SourceThe manufacturer’s generic port-count heading says “Thunderbolt 3”; this separate version field identifies the actual listed version. No older protocol is inferred from the heading.
SourceThe manufacturer explicitly lists positive stand height travel. Manufacturer-listed travel: 120.0mm(±5.0mm). Not calculated from the external height range.
SourceMatch the screw pattern, screw dimensions, product weight and mount load rating; the pattern alone does not verify a safe mount.
SourceManufacturer-listed travel: 120.0mm(±5.0mm). Not calculated from the external height range.
SourceManufacturer dimensions in the stated orientation; allow additional room for cables and movement. A listed height range is retained without inferring an adjustment travel.
SourceDepth from the manufacturer dimension tuple. Allow additional room for cable routing and movement.
SourceManufacturer width in the listed landscape configuration.
SourceNet product weight with the supplied stand or arm; packaging excluded.
SourceManufacturer dimensions in the stated orientation; allow additional room for cables and movement. A listed height range is retained without inferring an adjustment travel.
SourceManufacturer power figure under the stated operating mode; real use, brightness, connected USB devices and charging load can differ. Source mode: typical.
SourceManufacturer power figure under the stated operating mode; real use, brightness, connected USB devices and charging load can differ.
SourceManufacturer power figure under the stated operating mode; real use, brightness, connected USB devices and charging load can differ.
