HDMI Resolution Limited Fix

HDMI resolution limited on the HP ProBook 455 G11 Ryzen 5 7530U means the external monitor connected via HDMI shows a maximum resolution lower than the monitor native resolution in Windows Display Settings, such as the maximum available resolution being 1920×1080 when the monitor supports 2560×1440 or 3840×2160. The HP ProBook 455 G11 has an HDMI 2.0 port supporting up to 4K at 60Hz via the AMD Radeon Graphics integrated within the Ryzen 5 7530U Cezanne refresh platform.

Check HDMI cable version

Replace the HDMI cable with one rated HDMI 2.0 or higher. HDMI 1.4 cables are limited to 4K at 30Hz and 1080p at 60Hz. An HDMI 1.4 cable connected between the HP ProBook 455 G11 and a 4K or 1440p monitor may limit the maximum resolution Windows offers in Display Settings to 1920×1080 at 60Hz. Look for HDMI 2.0 or 18Gbps bandwidth rating on the cable packaging. High Speed HDMI (10.2 Gbps) is HDMI 1.4; Premium High Speed HDMI (18 Gbps) is HDMI 2.0.

Check monitor HDMI input version

Some monitors have multiple HDMI inputs where one is HDMI 2.0 and another is HDMI 1.4. Check the monitor user manual to confirm which HDMI port supports 4K or 1440p at 60Hz. Connect the HP ProBook 455 G11 HDMI cable to the monitor's HDMI 2.0 port. If the HDMI 2.0 monitor port requires a different cable connector orientation or location, the current connection may be using the lower-version HDMI port that limits maximum resolution.

Fix: Update AMD Display Driver from HP Support

Download the AMD Radeon Graphics driver for the HP ProBook 455 G11 Ryzen 5 7530U from HP Support. The HP-certified AMD driver includes the HDMI 2.0 EDID parsing configuration for the HP ProBook 455 G11 HDMI port. Without the HP-certified AMD driver, the generic Windows AMD driver may limit HDMI output resolution by reading monitor EDID data incorrectly through the HP ProBook 455 G11 HDMI 2.0 signal conditioning circuit and reporting the monitor maximum resolution as 1920×1080 rather than the actual 2560×1440 or 3840×2160 native resolution.

Fix: Create Custom Resolution in AMD Software

Open AMD Software: Adrenalin Edition. Navigate to Display → Custom Resolutions. Add the target resolution (e.g. 2560×1440 at 60Hz) manually with the correct horizontal and vertical timing parameters. This overrides the EDID-reported resolution limit and allows AMD Radeon Graphics to output at the correct resolution even if the EDID read from the monitor over the ProBook 455 G11 HDMI connection is truncated or incorrect. Test with the newly added custom resolution in Windows Display Settings after creating it in AMD Software.

Per Hamizah Abdul Jalil, content creator using HP ProBook 455 G11 Ryzen 5 7530U connected to a 1440p monitor: “HDMI on the ProBook 455 G11 was limited to 1080p even though the monitor supports 1440p. Replaced the old HDMI cable with a Premium High Speed HDMI 2.0 cable. The 2560×1440 resolution appeared immediately in Windows Display Settings after changing the cable. The old cable was HDMI 1.4 and could not carry the 1440p 60Hz signal from the HP ProBook HDMI port.”

Fix: Update HP ProBook 455 G11 BIOS

Download the latest BIOS for the HP ProBook 455 G11 from HP Support. BIOS updates include AMD display engine firmware for the Ryzen 5 7530U platform that configures the HDMI 2.0 controller output mode. An outdated BIOS can configure the HDMI output in compatibility mode that limits signal bandwidth to HDMI 1.4 specifications even though the physical HDMI port on the HP ProBook 455 G11 is HDMI 2.0 capable, preventing 4K and 1440p resolutions from being offered in Windows Display Settings.

Frequently Asked Questions

Why is HDMI resolution limited on HP ProBook 455 G11?

HDMI cable is rated HDMI 1.4 limiting maximum bandwidth, monitor is connected to an HDMI 1.4 input port instead of HDMI 2.0, AMD driver is reading monitor EDID incorrectly, or BIOS HDMI output is configured in compatibility mode. Replace with HDMI 2.0 Premium High Speed cable, connect to monitor HDMI 2.0 input, update AMD driver from HP Support, and update BIOS for AMD HDMI 2.0 output firmware.

What is the maximum HDMI resolution on HP ProBook 455 G11?

The HP ProBook 455 G11 HDMI port is HDMI 2.0 which supports a maximum resolution of 3840×2160 (4K UHD) at 60Hz or 2560×1440 at 144Hz with an HDMI 2.0 Premium High Speed cable and compatible monitor. The AMD Radeon Graphics in the Ryzen 5 7530U supports 4K output at 60Hz. For 4K at 60Hz from the HP ProBook 455 G11, use a Premium High Speed HDMI 2.0 rated cable and a 4K monitor with an HDMI 2.0 input port.

Does HP ProBook 455 G11 support 144Hz refresh rate via HDMI?

HDMI 2.0 supports up to 144Hz at 1920×1080 and up to 75Hz at 2560×1440. For 144Hz gaming monitor use at full resolution 2560×1440, the HP ProBook 455 G11 USB-C DisplayPort Alt Mode via a USB-C to DisplayPort 1.4 cable supports 2560×1440 at 165Hz with a compatible DisplayPort 1.4 monitor, providing higher refresh rates than HDMI 2.0 can deliver at the same resolution from the Ryzen 5 7530U AMD Radeon graphics output.

Why does my 4K monitor only show 30Hz on HP ProBook 455 G11 HDMI?

The HDMI cable is HDMI 1.4 which is limited to 4K at 30Hz (10.2 Gbps bandwidth). Replace with a Premium High Speed HDMI 2.0 cable (18 Gbps bandwidth) to enable 4K at 60Hz from the HP ProBook 455 G11 HDMI port. Confirm the 4K monitor HDMI port is also HDMI 2.0 capable. Then in Windows Display Settings, select the monitor and change the refresh rate from 30Hz to 60Hz to use the full HDMI 2.0 4K 60Hz bandwidth available from the HP ProBook 455 G11 AMD Radeon output.

Conclusion

HDMI resolution limited on the HP ProBook 455 G11 Ryzen 5 7530U is fixed by replacing the HDMI cable with a Premium High Speed HDMI 2.0 rated cable, confirming the monitor connection is to the HDMI 2.0 input port, updating the AMD Radeon driver from HP Support for correct EDID parsing, creating a custom resolution in AMD Software Adrenalin Edition, and updating BIOS for AMD HDMI 2.0 output firmware. The HDMI cable version being HDMI 1.4 instead of HDMI 2.0 is the most common and simplest cause of limited HDMI resolution on the HP ProBook 455 G11.
