The MEG 342C takes the performance lead with a 2% 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 MEG 342C tells a compelling value story. At $800 versus the LG C4 42" OLED's $800 price tag, it costs $0 less while delivering performance that's only 2% 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 MEG 342C is the smarter purchase. The LG C4 42" 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.
