The 1100Hz number is not the panel's native operating mode

G60H is a 27-inch Fast IPS display with a native resolution of 2560 × 1440.

Native QHD runs at up to 600Hz. Dual Mode moves to HD to reach the final 1100Hz specification.

Samsung originally announced 1040Hz at CES 2026. The company raised the finalized HD-mode specification to 1100Hz before the commercial launch.

Refresh interval falls from 1.67ms to 0.91ms

Six hundred refreshes per second give the panel approximately 1.67ms between cycles.

At 1100Hz, that becomes approximately 0.909ms.

Reducing resolution at the same time lowers the rendering workload, making the HD mode better aligned with the extreme frame rates required to make use of the additional refreshes.

A 1ms response specification needs context at 1100Hz

Samsung rates G60H at 1ms response time.

Refresh rate measures how frequently the panel is driven with a new frame. Response time describes how quickly pixels transition between states. A high value for one does not automatically guarantee ideal behavior for the other.

With less than a millisecond between refreshes, slow transitions could overlap subsequent scan cycles. Aggressive overdrive could instead produce inverse ghosting.

Full transition measurements across multiple gray levels will be necessary to establish how closely the Fast IPS panel follows its headline frequency.

The rendering system has the same sub-millisecond problem

Supplying a unique frame for every refresh at 1100Hz requires about 1100fps.

That gives the game and rendering pipeline around 0.91ms on average for each frame.

CPU simulation, draw-call submission, GPU execution and synchronization all consume part of that budget. An extremely fast graphics card alone cannot guarantee four-digit frame rates when the application is CPU-bound.

QHD at 600Hz remains an enormous data rate

A 2560 × 1440 frame contains about 3.69 million pixels. Repeating that 600 times each second means displaying more than 2.2 billion pixels per second before color depth and link overhead are considered.

Samsung lists DisplayPort 2.1 and HDMI 2.1 for the G60H, along with FreeSync Premium Pro, G-SYNC Compatible and HDR10+ Gaming.

The company's final Gamescom announcement does not provide a complete link-configuration breakdown for every extreme display mode.

Samsung changed the record without explaining the underlying change

CES documentation listed a 1040Hz HD maximum. The finalized launch specification is 1100Hz, while the 600Hz QHD mode remains unchanged.

Samsung has not publicly attributed those additional 60Hz to a specific panel revision, timing-controller change or overdrive modification.

Without that documentation, treating any one of those possibilities as the cause would be speculation.

The commercial specification is still incomplete

Samsung says the G60H will be available globally during the second half of 2026, with timing varying by market.

Pricing has not been announced.

The company has finalized the panel's fastest number. The cost of reaching it is still missing.
