Refresh problems on an AM5 motherboard setup look like a hardware fault but rarely are; the rate lives in display settings, the cable spec, and the GPU driver more than in any single part.

Quick Answer

Set the rate in Windows first: Advanced display settings, choose 144Hz, 165Hz, or 240Hz, apply. If the option is greyed out, the cable is the most common culprit, then the monitor's internal overclock or rate setting, then a GPU driver that needs a clean reinstall via DDU. Noting it again because this particular situation has its own quirks.

Enable the panel's own high-rate mode

Many monitors ship with their high-refresh or overclock mode switched off in the on-screen menu, and Windows can only offer rates the panel reports. Open the monitor menu, turn on the high-rate or OC option, save, then set the rate again in Windows. Adaptive sync or FreeSync settings live in the same menu and often need enabling for a smooth result. For an SA an AM5 motherboard setup setup, that is the cheapest, fastest move available.

Use a cable rated for the refresh you want

Bandwidth is the silent killer of high refresh. A 1440p 165Hz panel needs DisplayPort 1.4 or HDMI 2.1; an older HDMI lead trains down to 60Hz to stay stable. A proper cable runs roughly R450 to R1,200, far cheaper than the GPU or monitor people replace by mistake. Plug into the dedicated GPU ports, never the motherboard, when a card is installed. This matters more on an AM5 motherboard setup than the spec sheet ever suggests.

FAQ

Why does one monitor run high while the other stays at 60Hz?

Each display has its own refresh setting in Windows. Select the second monitor in Advanced display settings and raise its rate separately. A weaker cable or port on the second screen can also force it down to 60Hz. On an AM5 motherboard setup specifically, this step pays off more than any quick part swap.

Should I set the rate in Windows or the GPU control panel?

Set it in both so they agree. Windows Advanced display settings is the master, but the GPU control panel can override per-game, so a mismatch causes flicker or a drop back to 60Hz. Match them, then reboot to confirm. Treat an AM5 motherboard setup as its own case rather than copying a generic checklist.

Will a higher refresh rate hurt performance?

A higher refresh rate only shows frames the GPU already produces, so it does not reduce performance; it just removes the artificial 60fps ceiling. If frame rate is the limit, lower a few settings rather than the panel's refresh. For an AM5 motherboard setup in a South African home, that margin is worth protecting.

Match the monitor to your frame rate Once the refresh is set correctly, shortlist Evetech panels whose refresh matches what your GPU delivers so you pay for frames you will actually see. Stick with this for steady, repeatable results you can trust.
