Logitech G915 X LIGHTSPEED TKL

UK SKU 920-012720. The official UK image shows the ISO arrangement (tall Enter, £ on 3); US-layout SKUs are separate products.

Logitech states this weight without the cable.

Logitech labels these Length 368 mm, Width 150 mm and Height 22.6 mm.

Internet access for Logitech G HUB is listed as optional.

Width across the key rows (Logitech labels this Length).

Logitech lists this UK SKU with the Tactile style only; linear and clicky options are not offered for 920-012720. Logitech names the selected switch option “Tactile”. Capitalisation is normalised to the same explicitly supported GL tactile switch description as the wired G915 X; no region, switch family or configuration changes.

Tactile option; Logitech lists the linear option at 43 g.

Logitech does not state hot-swap support on the G915 X LIGHTSPEED TKL UK page.

Logitech does not list a rollover figure on the G915 X LIGHTSPEED TKL UK page.

The reviewed exact-model keycap passage does not establish supported keycap replacement.

Continuous-use claims. RGB must be disabled with the keyboard brightness button for the maximum figure; Logitech notes G HUB then reports no more than 236 hours. An additional 50%-brightness figure is published under a malformed label and is not used here.

Customisation uses Logitech G HUB. Original published inventory: KEYCONTROL with up to 15 functions per key. This common application name does not equate source-specific KEYCONTROL layers, per-key maxima, selected-key programming, rapid trigger, analog actions or Game Mode behaviour. Those exact positives and unresolved counterpart scopes remain separately represented.

Original published inventory: Soft-touch media keys and a cast iron roller bar. This common field records dedicated media-control availability only. Exact visible button labels, roller/buttons, lighting/Game Mode/profile controls and application dependence retain their own conditions; an omitted playback function or roller material is not a peer absence.

Logitech does not list a stored-profile count on the G915 X LIGHTSPEED TKL UK page.

The retained exact-product lighting description does not establish per-key lighting control; KEYCONTROL macro functions are a separate capability.

The exact source positively establishes programmable keys or assignments. This does not establish every key, a dedicated physical G-key count, a maximum function count or platform-independent operation. KEYCONTROL with up to 15 functions per key. Customisation uses Logitech G HUB.

The exact own-model source explicitly names KEYCONTROL. Its count and layered/analog scopes remain model-specific.

Manufacturer upper bound: up to 15 functions per key using KEYCONTROL/G HUB. This is an assignment-function maximum, not 15 physical keys or simultaneous actions.

The exact source/original establishes dedicated playback and track controls. G710+, G213 and Alloy Core originals additionally show a stop-labelled key; this does not establish an unlisted peer absence. Soft-touch media keys and a cast iron roller bar

A roller is positively listed/visible, but the exact retained source does not independently name its volume function. Preserve that roller positive and leave the precise volume-function mechanism unresolved. Soft-touch media keys and a cast iron roller bar

The own-model source/original positively shows a roller. Function, material and programmability remain independently conditioned; no absent peer roller is inferred.
