The market for affordable PC monitors priced under 400 euros includes a variety of options, from basic LCD screens for office tasks to high-performance models tailored for gaming and multimedia. The **TCL 27G64** is a Mini-LED monitor available for under 300 euros, featuring a 27-inch Quad HD (QHD) screen with an 180 Hz refresh rate, a VA panel, and a DisplayHDR 600 certification. It delivers high brightness (600 nits at peak) and strong contrast, though it may show halos in dark scenes and has limited viewing angles and dark trailing during fast movements. Connectivity options are limited to two HDMI 2.1 ports capped at 144 Hz, one DisplayPort 1.4, and no USB hub. The **Samsung Odyssey OLED G6 (G61SH)**, released in 2026, is a QD-OLED monitor with a 27-inch QHD panel, 240 Hz refresh rate, and a 0.03 ms response time. It provides deep blacks, excellent contrast, and covers 99% of the DCI-P3 color space. It supports HDR10+, AMD FreeSync, and Nvidia G-Sync, and includes an anti-reflection Glare Free feature and a thermal management system to prevent burn-in. However, it has limited connectivity with only one HDMI 2.1, one DisplayPort 1.4, and no USB-C Power Delivery port. The **Lenovo Legion 27Q-10** is a balanced option with a 27-inch 1440p IPS panel, a 240 Hz refresh rate on DisplayPort, and compatibility with AMD FreeSync Premium and Nvidia G-Sync. It includes an adjustable ergonomic stand and gaming software features such as Dark Boost mode and anti-blue light technologies. A QD-OLED version of the monitor is available at around 390 euros. The **Philips Evnia 34M2C3500L** is a 34-inch ultrawide curved monitor with a UWQHD (3440 × 1440) Fast VA panel, a 1500R curvature, and an 180 Hz refresh rate. It offers good native contrast but may exhibit dark trails on fast-moving content. The stand is only tiltable, though it includes a VESA mount for wall or desk mounting. The **Dell SE2725HG** is a budget-friendly option with a Full HD IPS panel, 200 Hz refresh rate, 1 ms response time, and compatibility with AMD FreeSync. It includes two HDMI ports, a DisplayPort, and a headphone jack. Its successor, the **Dell SE2726HG**, has a 240 Hz refresh rate and is available at an interesting price. For users seeking affordable options, the IPS panel is recommended for its good color rendering and wide viewing angles, while the VA panel offers higher contrast suitable for movies and dark games. OLED is praised for its deep contrasts and perfect blacks but is more expensive, typically requiring a budget of at least 400 euros. QHD resolution provides better clarity on 27-inch screens but may require a more powerful graphics card. A 27-inch monitor is now the standard for office use, while 24-inch Full HD remains popular for budget-conscious users. Mini-LED and OLED differ in their light control and brightness capabilities, with Mini-LED offering higher sustained brightness but potential halos on dark scenes and OLED providing perfect blacks but with a risk of burn-in. FreeSync and G-Sync both eliminate screen tearing, with G-Sync being more expensive due to its proprietary module. DisplayPort is recommended for high refresh rates and full support of adaptive synchronization technologies, while HDMI 2.1 is useful for console connections. A 34-inch ultrawide screen can offer immersion for gaming and multitasking but requires a powerful graphics card and sufficient desk space.
