Our verdict
The MPG 321URX takes the performance lead with a 15% higher overall score, driven by its more shader cores, more of memory, and higher TFLOPS of compute power. In gaming benchmarks at 1440p, it delivers roughly 0% more frames per second across demanding titles like Cyberpunk 2077 and Alan Wake 2.
However, the MPG 321URX tells a compelling value story. At $900 versus the LG C4 48" OLED's $1000 price tag, it costs 11% less while delivering performance that's only 15% behind. Its of memory is still more than enough for 1440p and even 4K gaming in most titles.
Our recommendation: for the majority of gamers targeting 1440p or even 4K with upscaling enabled, the MPG 321URX is the smarter purchase. The LG C4 48" OLED only makes sense if you need the absolute maximum performance for native 4K ray tracing, professional 3D rendering, or AI workloads where the extra VRAM and compute power provide a tangible advantage.
