When an RX 9070 XT build refuses to climb past 60Hz, treat it as a configuration chain: display mode, cable, monitor menu, then driver, in that order.

Quick Answer

Open Display settings, then Advanced display, and pick the panel's top rate from the refresh-rate menu. If only 60Hz appears, swap to a DisplayPort 1.4 or HDMI 2.1 cable, enable the high-rate mode in the monitor's own menu, and set the refresh again. A 144Hz panel that trains down usually has a cable or a stale GPU driver behind it. Noting it again because this particular situation has its own quirks.

Confirm the source can feed the rate

Some devices cap output. A handheld docked over USB-C, for example, may only push 60Hz unless DisplayPort Alt Mode and a capable dock are in play. Check the device's display output spec, then match the dock, cable, and panel so the whole chain supports the same rate end to end. This matters more on an RX 9070 XT build than the spec sheet ever suggests.

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. On an RX 9070 XT build specifically, this step pays off more than any quick part swap.

FAQ

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 RX 9070 XT build as its own case rather than copying a generic checklist.

Why is my refresh rate option greyed out?

A greyed-out rate almost always means the cable cannot carry it or the panel's high-rate mode is off. Swap to a DisplayPort 1.4 or HDMI 2.1 lead, enable the OC mode in the monitor menu, then reopen Advanced display settings and the higher rates should appear. For an RX 9070 XT build in a South African home, that margin is worth protecting.

Does the cable really affect refresh rate?

Yes, heavily. Refresh rate depends on bandwidth, and an under-spec cable trains down to a safe 60Hz rather than failing outright. For 144Hz and above at 1440p, a DisplayPort 1.4 cable is the safe default and costs around R450 to R900. Keep this tailored to an RX 9070 XT build and the result holds up the first time.

Get a panel that hits the rate out of the box If your screen tops out below what your GPU can drive, compare Evetech high-refresh monitors so the cable, panel, and card all support the same rate. Worth restating for this exact case, since the details rarely transfer cleanly.
