165Hz Monitor Test
A 165Hz refresh rate test confirms your IPS gaming panel is running at its rated 165Hz — a common step above 144Hz found on many mid-range IPS gaming monitors from LG, Samsung, and ASUS. 165Hz offers a modest 14% improvement over 144Hz, reducing per-frame display time from 6.9ms to 6.1ms. This test identifies if your display is truly hitting 165Hz or being capped at 144Hz, 60Hz, or another rate due to cable limitations or driver settings.

Frequently Asked Questions
Is 165Hz noticeably better than 144Hz?
The difference between 144Hz and 165Hz is very subtle — only a 14% increase in refresh rate. Most gamers cannot reliably distinguish 144Hz from 165Hz in blind tests. The benefit is most noticeable when your GPU is consistently outputting 165+ FPS, as you'll see slightly less tearing and marginally smoother motion. The jump from 60Hz to 144Hz is far more impactful than 144Hz to 165Hz.
Why does my 165Hz monitor show 144Hz?
Some 165Hz monitors are overclocked versions of 144Hz panels. In Windows, the 165Hz option may only appear after installing the monitor's ICC profile or driver from the manufacturer's website. Without the profile, Windows may only list standard VESA-certified rates (60/75/100/120/144Hz). Download the monitor's driver from the manufacturer's support page, install it, then check Display Settings → Advanced Display Settings.
What cable do I need for 165Hz?
DisplayPort 1.2 supports 1080p@165Hz and 1440p@144Hz. DisplayPort 1.4 is needed for 1440p@165Hz with full color depth. HDMI 2.0 supports 1440p@144Hz; getting 165Hz over HDMI requires HDMI 2.0 with DSC on supported monitors. Always use a certified DisplayPort cable (look for the DP logo) to ensure signal integrity at high refresh rates.
Do I need a special GPU for 165Hz?
Any modern GPU with a DisplayPort 1.2+ output can drive 1080p@165Hz. For 1440p@165Hz, you need at least a mid-range GPU (RTX 3060 / RX 6600 XT) to actually achieve 165 FPS in games. The GPU bottleneck matters — running a 165Hz monitor at 80 FPS still gives you lower input lag than 60Hz (VRR range) but you won't experience full 165Hz smoothness.
Does FreeSync or G-Sync work at 165Hz?
Yes. Most 165Hz monitors are FreeSync Premium certified and work with AMD GPUs and NVIDIA GPUs (via G-Sync Compatible mode). The VRR range is typically 48–165Hz. Some monitors also support ELMB (Extreme Low Motion Blur) backlight strobing at 165Hz, which sharpens fast motion at the cost of reduced brightness. Enable VRR in AMD Radeon Software or NVIDIA Control Panel.
How do I know if my 165Hz monitor is an overclocked 144Hz panel?
Technically, almost all 165Hz monitors use panels rated at 144Hz that are factory-overclocked to 165Hz. This is standard practice and doesn't reduce quality — manufacturers validate the overclock before shipping. You can identify this in GPU-Z or HWiNFO sensor logs which show the actual panel EDID data. For consumer purposes, if the monitor is marketed as 165Hz and passes this refresh rate test, it's performing as intended.
