I've been PC gaming since 2019 and have used 27–32-inch 1440p monitors at 144Hz for years. I'm keeping my main 1440p 144Hz monitor for competitive games, but I'd like a TV beside my setup for single-player and more relaxed gaming, especially with my Xbox Series X. The TV would be roughly 2 metres away, or possibly around 2.5 metres if I eventually add a couch.
I'm considering a 4K QLED because OLED TVs seem too expensive in Australia, and my budget is around AUD 800. I'm unsure whether 43, 50, or 55 inches would be the best size, and whether dropping from 144Hz to 4K 60Hz would feel very noticeable for slower-paced games. I'd also appreciate advice on brands, important gaming features, HDMI requirements, and whether there are any good-value 4K 120Hz options in Australia.

A 55-inch OLED at around 2.5 metres can be an excellent gaming display, especially if you use a controller, but OLED pricing may not fit your Australian budget. If you go with QLED or another LCD model, prioritize low input latency, a responsive game mode, 4K resolution, and HDMI 2.1 if you want 4K at 120Hz from the Xbox or a capable PC. Also check whether the PC input supports the desired refresh rate, since some TVs only provide 120Hz on specific HDMI ports.
At roughly 2–2.5 metres, 55 inches is a very reasonable size for couch-style gaming and probably more immersive than 43 or 50 inches. A modern 4K TV with a proper game mode, low input lag, and variable refresh rate should work well for both a PC and an Xbox Series X. Just check the exact model’s HDMI features rather than assuming every 4K TV supports high refresh rates.
A 4K 60Hz set will be noticeable compared with your 144Hz monitor, particularly for shooters and mouse-driven games, but it can still be perfectly enjoyable for single-player games with a controller. If you can find a 4K 120Hz model within budget, that would be the nicer long-term choice, but I wouldn’t sacrifice image quality or gaming features just to chase a higher refresh number.
That makes sense. The TV would mainly be for slower single-player games, while I’d keep the monitor for competitive titles, so 60Hz may be acceptable if the rest of the TV is good.

I’ll definitely check the individual HDMI ports and PC compatibility. I had assumed all of the ports on a newer 4K TV would have the same features.
