Separate the launch monitor from the software that drives the screen
A launch monitor can measure shots without dictating one universal computer requirement. The same device may support a simple practice app on a mobile device and a more demanding third-party simulator program on a Windows PC. That is why a product page that says a monitor works with a phone does not prove that every course package you might add later will run on that phone.
Our editorial recommendation is to write down the exact software you expect to use before shopping for a computer. Include the manufacturer app, any course-play subscription, and any third-party simulator program you may want. Treat the strictest requirement in that planned stack as the requirement for the build. If you have not chosen the software yet, postpone the PC purchase rather than guessing.

A standalone unit can remove the PC from one specific workflow
Garmin's Approach R50 manual describes Home Tee Hero virtual rounds as running on the Approach R50 device with a Garmin Golf membership. Garmin also documents a direct HDMI connection from the R50 to an external display. For that manufacturer-described workflow, a separate PC is not part of the path between the launch monitor and the display.
That does not mean every R50 software option is computer-free. It means buyers who are satisfied with the on-device Garmin experience have a credible no-PC route to investigate. If you later choose third-party software, check that software separately. A projector or television also remains a separate display decision even when the simulator engine is inside the launch monitor.

Mobile compatibility can be enough for practice, but not for every simulator program
Rapsodo's current golf FAQ says the MLM2PRO is compatible with most versions of iOS and Android, so its core mobile workflow does not automatically require a gaming PC. That can be attractive when the goal is shot data, practice sessions or supported mobile experiences and you already own a suitable phone or tablet.
The computer requirement changes when the software changes. Rapsodo's GSPro integration page lists Windows 10 or 11, an Intel i5 or AMD-equivalent processor, 8 GB of RAM, a GTX 1070-or-better graphics card and 20 GB of free disk space as minimum requirements for that integration. The useful buying lesson is not that one platform is better; it is that the same launch monitor can move from a mobile-first setup to a dedicated-PC setup when you add a different simulator application.
Software requirements change over time, so verify the current integration page again before ordering a computer. Do not assume that a PC specification copied from a forum, old video or another simulator package applies to your exact software version.

SKYTRAK shows why platform support and performance requirements are two different questions
SKYTRAK provides downloads for Windows, macOS, iOS and Android. That broad platform support is useful, but it should not be read as a promise that every SKYTRAK feature or every third-party simulator title has identical hardware needs on every platform.
For buyers planning a Windows setup, SKYTRAK's current membership page publishes minimum specifications for its newer application that include Windows 10 64-bit or newer, 8 GB of RAM, an Intel i3-10100F or AMD Ryzen 2600, and an Nvidia GTX 1650 or AMD Radeon 580. Those are manufacturer minimums for the referenced SKYTRAK software, not a universal specification for every course engine, projector resolution or future feature.
The practical approach is to choose the software tier and display resolution first. If your selected simulator software recommends more hardware than SKYTRAK's base application, budget for the higher requirement. Buying only to the launch monitor app's minimum can create an avoidable second computer purchase later.

Some ecosystems are explicitly PC-centered
Uneekor publishes dedicated computer requirements for its simulator software. Its current software information lists 16 GB of RAM and an Nvidia RTX 3060 or equivalent with 12 GB of graphics memory among the minimum specifications shown for its software environment. That is a materially different starting point from a mobile-only practice setup.
For a buyer, the important distinction is architectural: if the software experience you want is designed around a Windows gaming-class computer, the PC is a core simulator component rather than an optional accessory. Plan its location, ventilation, network connection, video cable path and access for updates at the same time you plan the projector and launch monitor.
Do not buy a computer from a single component label such as 'RTX 3060' alone. Confirm the full current requirement table, the simulator software you will run, the display resolution and any additional camera or swing-analysis software. The slowest required component can become the practical limit.

Budget the computer as part of the whole system, not as an afterthought
A no-PC simulator is not automatically the least expensive system, and a gaming-PC system is not automatically poor value. The total cost depends on what you already own and which experience you are buying. A standalone device may concentrate more capability in the launch monitor, while a PC-based system may give you a different software catalog or upgrade path.
Make one equipment list that includes the launch monitor, computer or mobile device, display or projector, required adapters and cables, screen or net, enclosure, hitting mat, software memberships and any installation hardware. Use current quotes rather than generic price assumptions. If a software choice forces a computer upgrade, assign that cost to the software decision so comparisons stay honest.
Also account for physical installation. A desktop PC needs a protected location outside the swing and ball-impact area, and cable runs should not create trip or snag hazards. Follow the equipment and room-installation instructions for the products you actually buy; computer compatibility does not establish that a room is suitable for swinging a club.

Use a three-question test before buying a gaming PC
First, what exact experience do you want on day one: range practice, manufacturer course play, or a specific third-party simulator program? Second, what device does that exact software currently require? Third, what is the highest recommended specification across every program you intend to run? Those answers are more useful than asking whether the launch monitor 'needs a computer.'
If your chosen workflow is mobile or standalone, start with that path and confirm how it connects to the display you want. If your chosen software requires Windows graphics hardware, buy to the current software recommendation with reasonable upgrade headroom rather than the bare minimum when your budget allows. If you are still undecided, keep the computer out of the cart until the software decision is settled.
This is a source-based buying framework, not a hands-on performance test. Manufacturer requirements establish compatibility targets, but they do not guarantee frame rate, image quality or future software support in every configuration. Recheck the current requirements immediately before purchase.

Start with the room—not the shopping cart
Use the calculator as an initial planning screen. Confirm the complete layout with the equipment supplier before purchase.
