What causes display tearing
GPU framerate exceeds the display refresh rate. The Alienware x14 R2 has a 165Hz display. Games rendering above 165 FPS will produce visual tearing if V-Sync is disabled and G-Sync is not active. The NVIDIA GeForce RTX 4060 in the x14 R2 can easily exceed 165 FPS in lighter titles.
G-Sync is not enabled in NVIDIA Control Panel. The Alienware x14 R2 165Hz display supports G-Sync. G-Sync synchronizes the GPU framerate to the display refresh rate, eliminating tearing when G-Sync is within the supported range (30Hz to 165Hz on the x14 R2 display).
The MUX Switch on the Alienware x14 R2 is set to Hybrid mode (Optimus). In Hybrid mode, the Intel Arc integrated GPU renders frames and G-Sync is not available. Switching to dGPU Only MUX mode enables G-Sync on the 165Hz panel.
Fixes
Enable G-Sync in NVIDIA Control Panel: Open NVIDIA Control Panel → Display → Set up G-SYNC. Check Enable G-SYNC, G-SYNC Compatible and select the Alienware x14 R2 display. Open Manage 3D settings → Global Settings and set Monitor Technology to G-SYNC. Also set Vertical sync to On in Global Settings — enabling V-Sync alongside G-Sync prevents framerate spikes above the G-Sync ceiling (165 FPS) that would produce tearing above the variable refresh range.
Switch MUX to dGPU Only Mode: Open Alienware Command Center → Game Library → Graphics or BIOS (F2) → Advanced → Graphics Mode and switch from Hybrid to dGPU Only. This connects the NVIDIA RTX 4060 directly to the display output, bypassing the Intel Arc iGPU buffer that prevents G-Sync from operating in Hybrid (Optimus) mode. A restart is required after switching. dGPU Only mode enables G-Sync at full 165Hz and eliminates tearing completely at framerates within the G-Sync range.
Update NVIDIA Driver via Dell SupportAssist: Open Dell SupportAssist and install any pending NVIDIA GeForce driver update for the Alienware x14 R2. An outdated NVIDIA driver may have G-Sync initialization bugs or framerate cap issues that cause tearing even with G-Sync enabled in NVIDIA Control Panel. Dell-certified NVIDIA drivers for the x14 R2 include Alienware-specific G-Sync profile corrections.
Per Aiman Yusoff, competitive gamer using Dell Alienware x14 R2 for FPS gaming: “Screen tearing on the x14 R2 was constant in games despite G-Sync being listed as supported. The display was in Hybrid MUX mode, which disables G-Sync. Switching to dGPU Only in Alienware Command Center and enabling G-Sync in NVIDIA Control Panel eliminated all tearing immediately.”
Frequently Asked Questions
Why does the Dell Alienware x14 R2 have display tearing?
G-Sync is not enabled in NVIDIA Control Panel, the MUX switch is in Hybrid mode which disables G-Sync, or the NVIDIA driver needs updating. Enable G-Sync in NVIDIA Control Panel and switch the MUX to dGPU Only mode in Alienware Command Center or BIOS for tear-free gaming on the 165Hz display.
Does the Dell Alienware x14 R2 support G-Sync?
Yes. The Alienware x14 R2 165Hz display is G-Sync compatible when the MUX switch is set to dGPU Only mode. G-Sync is not available in Hybrid mode because the Intel iGPU mediates all display output and G-Sync requires direct NVIDIA GPU control of the display signal. Switch to dGPU Only MUX mode for G-Sync operation.
Does switching to dGPU Only mode reduce battery life on Alienware x14 R2?
Yes. dGPU Only mode keeps the NVIDIA RTX 4060 active for all rendering, including desktop and light tasks that would normally use the more efficient integrated GPU in Hybrid mode. Battery life decreases by approximately 30 to 50 percent in dGPU Only mode compared to Hybrid mode. Use dGPU Only mode when plugged in for gaming and Hybrid mode for battery-powered productivity work.
Should I set V-Sync on or off alongside G-Sync on Alienware x14 R2?
Enable V-Sync in NVIDIA Control Panel Global Settings when using G-Sync. V-Sync with G-Sync works differently from V-Sync alone: G-Sync handles synchronization within the 30 to 165Hz range, and V-Sync acts as an upper framerate cap above 165Hz to prevent tearing from framerate spikes above the G-Sync maximum. The combination gives tear-free output across all framerate ranges.
Conclusion
Display tearing on the Dell Alienware x14 R2 i9-13900HX is fixed by switching the MUX mode to dGPU Only in Alienware Command Center, enabling G-Sync in NVIDIA Control Panel Display settings, and setting V-Sync to On in NVIDIA Control Panel Global 3D Settings. Update the NVIDIA driver via Dell SupportAssist for Alienware-specific G-Sync profile corrections. G-Sync requires dGPU Only MUX mode and the NVIDIA RTX 4060 directly connected to the 165Hz display output without the Intel iGPU buffer in the rendering path.
