The LG 45GX950A-B is simply a better monitor in almost every way that matters for gaming — bigger, more immersive, and with the kind of picture quality that makes Reddit and professional reviewers agree for once. The MSI MPG 271QRX wins on exactly two things: the 360Hz refresh rate for competitive play and the USB-C port that makes it a genuine work-and-game hybrid. If you're not playing CS2 at a high rank or plugging in a MacBook, the LG is the obvious choice.

The LG is a 45-inch curved OLED. The MSI is a 27-inch flat panel. That's not a minor spec gap — it's the difference between sitting inside a game and looking at one. For RPGs, racing sims, or anything cinematic, the LG's curved ultrawide wraps your peripheral vision in a way the MSI simply cannot replicate. But that same size means you need a serious desk and the right viewing distance, or it becomes overwhelming.
The MSI's 360Hz is a genuine competitive advantage if you're playing at a level where frame timing actually affects your aim. For the vast majority of gamers, the LG's high refresh rate is more than enough and the difference is imperceptible. But if you're grinding ranked in a fast-paced shooter and every millisecond counts, the MSI's refresh rate is the real deal — not a marketing number.
The MSI's USB-C port sounds like a minor spec until you realize it means one cable connects your laptop for work, charges it, and drives the display at full resolution. The LG has no USB-C. If you're switching between a gaming PC and a work laptop daily, the MSI's cable management advantage is real and you'll notice it every single day. The LG forces you to manage multiple cables and inputs.
The MSI starts at $500. The LG starts at $1,200. That $700 difference at the low end is enough to buy a meaningful GPU upgrade, a mechanical keyboard, or a second peripheral. The LG is worth it if you're building a premium setup and the monitor is the centerpiece. But if you're budget-conscious or just want a great OLED gaming monitor without the flagship price, the MSI delivers most of the OLED experience for far less.
