Daisy chaining sends the second screen's picture out of the first monitor's DisplayPort output. The Dell Pro 24 Plus P2425DE carries that output and runs 2560 x 1440 at 100Hz, and Evetech has it at R6,099.
One laptop, one cable to the first screen, and a second QHD monitor picking up from there: that is the whole promise of DisplayPort daisy chaining, and it works because the first monitor does more than just display a picture. At R6,099, the Dell Pro 24 Plus P2425DE carries the DisplayPort output that makes it possible.
Daisy chaining sends a second video signal out of the first monitor's DisplayPort output socket, so a single cable from the laptop can eventually feed two separate screens. The Dell Pro 24 Plus P2425DE carries that output and runs at 2560 x 1440 and 100Hz, and Evetech has it at R6,099.
The laptop is not sending one picture twice. It is sending two separate video streams down one connection using Multi-Stream Transport.
The single USB-C or DisplayPort cable from the laptop carries both streams to the first monitor. That monitor keeps the stream meant for it and passes the second one out through its own DisplayPort output socket to the next screen in the chain. Each monitor shows its own part of the desktop, extended or duplicated as Windows is configured, rather than the second screen simply mirroring the first.
This only works with monitors that specifically support DisplayPort Out for daisy chaining, and it needs Multi-Stream Transport switched on somewhere in the chain, usually the first monitor's own on-screen menu.
Order matters here, more than with a single monitor setup.
Connect the laptop's video output to the first monitor's input port, then run a DisplayPort cable from that first monitor's DisplayPort Out socket to the second monitor's DisplayPort input. Power both screens on before connecting the laptop, then open the first monitor's on-screen menu and look for a setting named MST, Multi-Stream Transport or DisplayPort 1.2, and switch it on if it is not already active. Windows should then detect two separate displays under Settings, then System, then Display, where you can arrange them to match their physical position on the desk.
When the second screen does not appear, the fault is almost always one of a small number of things.
Check that MST is switched on in the first monitor's menu before anything else, since it defaults to off on many models. Confirm the second monitor is receiving on its DisplayPort input specifically, not HDMI. Try a different DisplayPort cable, since a damaged or underrated one is a common and easily missed cause. Finally, confirm the laptop's own video output actually supports MST, since not every USB-C port that carries a picture also supports passing a second stream through a chain.
Compare panels built for this in the office monitor range, pick up the right lead in monitor accessories, and browse the wider monitor category if you are shopping for the second screen in the chain.
There is a ceiling on how much video data one connection can carry, and it is worth understanding before assuming any two monitors will chain together at full quality.
A single DisplayPort or USB-C video connection has a fixed total bandwidth, and running two 2560 x 1440 screens at 100Hz through Multi-Stream Transport uses a meaningful share of it. Most modern laptops with proper MST support handle two QHD panels at 60Hz comfortably; pushing both to 100Hz simultaneously depends on exactly which DisplayPort version the laptop's output uses. If the second screen in the chain appears but runs at a lower refresh rate than expected, that is usually the connection reaching its bandwidth ceiling rather than a fault, and dropping one screen to 60Hz while keeping the other at 100Hz is a common practical compromise that still leaves both screens fully usable for everyday work.
The first monitor needs a DisplayPort Out socket and MST support. The second, end-of-chain monitor only needs a standard DisplayPort input.
Sometimes, depending on the graphics output's total bandwidth and how many monitors in the chain also carry a DisplayPort Out socket of their own.
Not meaningfully at standard office resolutions and refresh rates, though very high combined resolutions across several screens can approach the bandwidth ceiling of the connection.
Check the display arrangement in Windows Settings, then System, then Display. Extend is a display mode choice separate from whether the physical daisy chain itself is working.
Yes. Only the video signal passes through the DisplayPort Out socket; each monitor in the chain still needs its own mains power connection.

Gaming PC lagging often comes from network delay, background apps, heat, storage issues, or mismatched settings. Work through quick checks before spending on parts for an SA gaming setup, then retest one change at a time.

Keychron G6 HE has built-in and swappable battery versions with different weights. The product brief lists 42g and 46g respectively, each with a 3g tolerance. Choose by grip and battery preference before treating one headline weight as universal.
Corsair HS80 v2 MAX supports 2.4GHz wireless and Bluetooth. Its maximum battery figures use RGB-off conditions and differ by connection. Check microphone routing, comfort and the exact device support before assuming every wireless mode behaves alike.
Windows taskbar notification badges can be shown or hidden in Taskbar behaviours. This changes the small app indicators, not the underlying messages. Choose a calmer desktop while keeping a deliberate routine for checking important conversations and app updates.
Windows title bar window shake can minimise other open windows when you shake the active window by its title bar. Inspect the Multitasking setting and switch it off if that gesture interrupts your work. The preference costs R0 and does not require new hardware.
Windows Print Screen opens Snipping Tool when its keyboard preference is enabled. Change the option under Accessibility, Keyboard to choose another workflow. Test whether you need a clipboard image or a saved file.
Windows desktop icons missing may be a visibility setting. Right-click the desktop, choose View and inspect Show desktop icons. If only system icons are absent, use Desktop icon settings. Check the Desktop folder before assuming files were deleted.
Windows set time zone automatically greyed out calls for a location and device-policy check. Automatic time-zone selection relies on location services. A manual time-zone choice is separate from synchronising the clock; check both before replacing hardware.
Windows transparency effects can be switched off to make supported backgrounds more opaque. Use Accessibility, Visual effects or the colour settings, then compare a menu against your wallpaper. This R0 preference changes appearance; it is not a promised.
