Yes, you can connect a PS4 to a 4K gaming monitor, but the actual resolution and features you get depend on which PS4 model you own.
Identifying Your PS4 Model’s Capabilities
The PS4 Pro is the only model that can output native or checkerboard 4K at up to 60Hz. This official PlayStation FAQ confirms the Pro supports 4K output while earlier models do not.
Original PS4 and PS4 Slim consoles are limited to 1080p. They still benefit from the higher pixel density of a 4K panel, but the image is always scaled.
All PS4 models support HDR10 when updated to firmware 4.0 or later. PlayStation’s HDR setup guide explains that HDR works across the entire PS4 lineup, giving base-model owners improved color and contrast even without 4K resolution.
HDMI Cables and Port Compatibility
A Premium High Speed HDMI cable (HDMI 2.0) is required for 4K/60Hz output from the PS4 Pro. PlayStation’s official 4K and HDR guide states that older High Speed cables may limit you to 1080p or cause flickering.
Check that the monitor’s HDMI port supports HDMI 2.0 or 2.1. Ports limited to HDMI 1.4 will cap the signal at 4K/30Hz and can introduce noticeable lag. This HDMI specification overview explains the bandwidth differences.
KTC monitors such as the H27P6 include HDMI 2.1 ports that easily handle PS4 Pro signals while also supporting dual-mode 1080p 320Hz for PC use.
Optimizing Image Quality and Scaling Settings
1080p content on a 4K screen can appear soft because the monitor must interpolate the image. Enable the monitor’s “Super Resolution” or sharpening filter in the OSD to restore edge definition without touching console settings.
For PS4 Pro users, set the console output to 2160p – RGB and turn monitor sharpening off to avoid ringing artifacts. Also enable “HDMI Enhanced Mode” or “UHD Color” on the monitor so HDR and full color depth remain active.
Supersampling Mode on the PS4 Pro is designed for 1080p displays and turns off automatically when a native 4K monitor is detected.
The Shared Desk: PS4 and PC Hybrid Setup
Many users run both a PS4 and a PC on the same 4K monitor. Enable HDMI-CEC (sometimes labeled HDMI Device Link) so the monitor wakes and switches inputs when you press the PS4 controller.
Base and Slim models lack an optical audio port, so route sound through the monitor’s 3.5 mm headphone jack to your speakers or headset.
A 4K panel is the better hybrid choice than 1440p because 1080p scales cleanly at a 2×2 ratio. The H27P22S offers full ergonomic adjustment and dual HDMI 2.1 ports, making input switching between console and PC straightforward.
Troubleshooting No Signal and Black Screen Issues
A black screen after connecting a PS4 Pro often stems from an HDCP 2.2 handshake failure. Boot the console into Safe Mode and set HDCP to 1.4, as described in Sony’s troubleshooting article.
Confirm HDR is enabled on both the PS4 and the monitor. A mismatch here frequently drops the signal. Reseat the HDMI cable firmly; 4K signals are more sensitive to loose connections or damaged cables than 1080p.
If the monitor still shows no picture, test the same cable and port with another device to isolate whether the issue is the console, cable, or monitor input.
