# But at what cost... - LG GX7 Source: https://www.youtube.com/watch?v=55U_hNqfRwY Recap page: https://rapidrecap.app/video/55U_hNqfRwY Generated: 2025-10-21T20:02:13.674+00:00 --- ## Quick Overview The LG UltraGear GX7 27-inch 1440p 280Hz OLED monitor delivers incredible gaming performance with a measured 2.4ms latency at 280Hz and 6.7ms latency at 120Hz, along with excellent color coverage, achieving 84.2% of the BT.2020 color space in HDR mode, though the high peak brightness is only sustained for small windows. **Key Points:** - The LG UltraGear GX7 is a 27-inch, 1440p, 280Hz OLED gaming monitor featuring VESA DisplayHDR True Black 500. - Measured latency is extremely low: 2.4ms at 280Hz and 6.7ms at 120Hz, which is slightly over the theoretical perfect latency. - Color accuracy in sRGB mode (100% coverage) shows an average dE2000 of 1.55, which is very respectable. - HDR color coverage is strong, achieving 84.2% of the BT.2020 color space (and 99.5% P3 coverage). - Peak luminance reached 1744 nits in a 1% window, but sustained full-screen brightness dropped to around 400 nits. - The monitor includes 2x HDMI 2.1 ports, 1x DisplayPort 1.4, and USB 3.0 Type-B/Type-A ports, plus a mic/headphone combo jack. - The stand features a sleek, razor-thin design with 110mm of height adjustment and 90 degrees of pivot rotation (counter-clockwise only). ![Screenshot at 00:06: The host stands behind the massive box labeled 'LG UltraGear GX7', signaling the start of the unboxing for the 27-inch 1440p 280Hz OLED gaming monitor.](https://ss.rapidrecap.app/screens/55U_hNqfRwY/00-00-06.png) **Context:** This video presents an unboxing and initial impressions review of the LG UltraGear GX7, a high-refresh-rate OLED gaming monitor, focusing on its physical setup, included accessories, color accuracy metrics, and input latency performance during gaming tests, while also noting the monitor's high peak brightness capability in HDR. ## Detailed Analysis The video begins with the unboxing of the LG UltraGear GX7 monitor, noting the large, fragile packaging and identifying the included accessories: a heavy, solid metal stand with a flat base, a C8 power brick (not C13), a USB Type-B to Type-A cable, an HDMI 2.1 cable, and a DisplayPort 1.4 cable. The host praises the stand's solid build and sleek design, mentioning it allows for 110mm of height adjustment and 90 degrees of counter-clockwise pivot, but critiques the external power brick and the lack of speakers. Once set up, the monitor is tested for performance, showing excellent response times with a 0.03ms Gray-to-Gray (GtG) rating and measured latency of 2.4ms at 280Hz and 6.7ms at 120Hz, making it excellent for fast-paced games like CS:GO. Color testing in sRGB mode at 100% brightness yielded a very good average dE2000 of 1.55. In HDR testing, the monitor achieved 1744 nits peak brightness in a 1% window, but sustained brightness dropped significantly to about 400 nits for full-screen content, which is typical for OLEDs. The monitor covers 99.7% of P3 and 84.2% of BT.2020 color space. The host concludes that despite the pricing, the performance is impressive for an OLED panel. ### Unboxing and Accessories - Host carefully unboxes the large LG UltraGear GX7, noting the heavy metal stand with a flat base - Included accessories feature a C8 power cable (not C13) and cables for DP 1.4 and HDMI 2.1 - Stand allows 110mm height adjustment and 90-degree counter-clockwise pivot. ### Connectivity and Design - Ports include 2x HDMI 2.1, 1x DisplayPort 1.4, 1x USB Type-B, 2x USB Type-A (all USB 3.0), and a mic/headphone combo jack - The rear panel features a subtle LG UltraGear logo and ventilation fins, which the host likes. ### Performance Metrics - Measured GtG response time is 0.03ms - Input latency is 2.4ms at 280Hz and 6.7ms at 120Hz, which is very fast for an OLED. - The monitor supports FreeSync Premium Pro and G-SYNC Compatible. ### Color and Brightness Testing - sRGB mode shows excellent color accuracy with Avg dE2000 of 1.55 - HDR testing reveals a peak luminance of 1744 nits (1% window) but sustained full-screen brightness drops to ~400 nits - Color gamut coverage reaches 99.7% P3 and 84.2% BT.2020. ![Screenshot at 00:04: The host points out the 'Life's Good GX7' sticker on the large shipping box.](https://ss.rapidrecap.app/screens/55U_hNqfRwY/00-00-04.png) ![Screenshot at 00:33: The host holds up the heavy, solid metal monitor stand base and arm, noting its substantial weight.](https://ss.rapidrecap.app/screens/55U_hNqfRwY/00-00-33.png) ![Screenshot at 00:48: The host displays the monitor stand arm, noting its dual-tone purple/grey color and sleek design.](https://ss.rapidrecap.app/screens/55U_hNqfRwY/00-00-48.png) ![Screenshot at 01:21: The host displays the included C8 power cable, mentioning he will use a different regional plug.](https://ss.rapidrecap.app/screens/55U_hNqfRwY/00-01-21.png) ![Screenshot at 02:04: On-screen overlay lists connectivity features including HDMI 2.1 and DisplayPort 1.4.](https://ss.rapidrecap.app/screens/55U_hNqfRwY/00-02-04.png) ![Screenshot at 03:23: The host demonstrates the 90-degree counter-clockwise pivot capability of the stand.](https://ss.rapidrecap.app/screens/55U_hNqfRwY/00-03-23.png) ![Screenshot at 05:34: Close-up of the I/O panel showing 2x HDMI 2.1, 1x DP 1.4, and USB ports.](https://ss.rapidrecap.app/screens/55U_hNqfRwY/00-05-34.png) ![Screenshot at 07:06: The monitor displays a test pattern showing 111 PPI density for the 27-inch 1440p resolution.](https://ss.rapidrecap.app/screens/55U_hNqfRwY/00-07-06.png) ![Screenshot at 10:02: Latency test results show 2.4ms latency at 280Hz, which is only 0.6ms over theoretical perfect.](https://ss.rapidrecap.app/screens/55U_hNqfRwY/00-10-02.png) ![Screenshot at 10:55: ColorChecker graph for sRGB mode showing a very good average dE2000 of 1.55.](https://ss.rapidrecap.app/screens/55U_hNqfRwY/00-10-55.png) ![Screenshot at 11:10: Chromaticity Area chart showing excellent color space coverage, including 84.2% of BT.2020.](https://ss.rapidrecap.app/screens/55U_hNqfRwY/00-11-10.png)
