Repair common Windows errors and clear accumulated junk for a smoother, more stable PC - no reinstall needed.Free scan · no reinstallSamsung’s 2026 R95H is one documented TV with a 240Hz gaming mode, but not at 4K: Samsung lists a standard refresh rate of 165Hz and specifies 2K at 240Hz for supported PC games with Game Mode enabled. TCL’s C84/C845 offers a different 240Hz mode that runs at Full HD. The key buying question is therefore not just whether a TV says “240Hz,” but what resolution and source device that rate requires.
What does “240Hz” mean on a TV?
A 240Hz mode can describe a TV’s ability to display up to 240 images per second in a particular gaming configuration. It does not necessarily mean the panel runs at 240Hz at its full 4K resolution. Manufacturers may use a mode such as DLG (Dual Line Gate) to reach the higher stated rate while reducing the game’s resolution.

That distinction matters because resolution and refresh rate answer different questions: resolution affects image detail, while refresh rate describes how often the display can update. A TV advertised with 240Hz may trade some detail for smoother motion at that rate.

Samsung R95H: 4K at up to 165Hz, or 2K at 240Hz
Samsung Canada describes supported PC gaming at up to 4K 165Hz or 2K 240Hz. Its product specification separates “Refresh Rate 165 Hz (VRR Support)” from “DLG 240 Hz,” so the 240Hz figure should be understood as a gaming mode rather than a 4K 240Hz specification. Samsung’s gaming-TV page also ties these modes to PC-connected games that support the relevant specification and a PC graphics card.
TCL C84/C845: 240Hz at Full HD
TCL’s Switzerland page says the C84 series reaches 240Hz using DLG and automatically sets the game resolution to Full HD. This is another example where the advertised maximum rate depends on a lower resolution than 4K.

Can a console use a TV’s 240Hz mode?
Do not assume so. Samsung’s cited 2K 240Hz conditions specify PC-connected games and a PC graphics card. The available product information does not establish that a console can use that mode. Check the exact TV’s specifications for the console input mode and the console’s supported output before choosing a TV for this purpose.
How to check a 240Hz TV before buying
- Find the exact model and size. Verify the full model code, screen size, and regional version on the manufacturer’s local product page. A family name alone does not establish that every size has the same refresh options.
- Read the resolution-and-refresh combination. Look for the resolution explicitly paired with 240Hz, such as 2K or Full HD, and distinguish it from the TV’s standard or native refresh-rate specification.
- Check what creates the mode. Determine whether the advertised figure is a DLG or other gaming mode, and note any required Game Mode setting, PC graphics card, or compatible game.
- Match the TV to the source device. If you plan to use a console, confirm that the specific input and console support the desired resolution and refresh rate; do not infer console compatibility from a PC gaming claim.
- Compare the rest of the TV, too. Once the mode fits your setup, compare picture quality, price, ports, and HDR-format support. A refresh-rate headline alone does not establish which TV is best overall.
Samsung’s support manual warns that specifications may differ by region. It lists the 2025 QN990F (except the 98-inch model) and QN950F in an “up to 240 Hz” group, but check the precise local model and size rather than treating a family-level listing as universal: Samsung support manual.

Is a 240Hz TV worth choosing?
It can make sense if your gaming PC can output the specified resolution and refresh rate and you value the smoother motion enough to accept the mode’s resolution trade-off. If your priority is 4K detail, compare the TV’s supported 4K refresh rate instead of relying on a 240Hz headline. If you mainly use a console, verify its supported TV mode directly before paying for a feature described for PC gaming.
