The Dell Latitude 3350 is an education-focused laptop using the Intel Core i3-N305 (Alder Lake-N) processor with Intel UHD Graphics (Jasper Lake). HDMI output is provided through the Intel UHD GPU. When the HDMI port produces no signal on a connected monitor — the screen stays blank or shows no signal — the fix is usually a display driver update, Windows display detection, or a monitor compatibility issue.
Fix 1 — Force Windows to Detect the External Display
Connect the HDMI monitor and press Windows + P to open the Project menu. Cycle through options (Duplicate, Extend, Second screen only) to force Windows to re-detect the connected display. If no display appears, press Windows + Ctrl + Shift + B to reset the graphics driver without a full reboot.
Right-click the Desktop > Display settings > scroll down to Multiple displays > click Detect
Ensure the HDMI monitor is powered on before connecting the cable — some monitors are not detected if powered off when the cable is inserted
Fix 2 — Update Intel UHD Graphics Driver
Visit Dell Support, enter your Latitude 3350 service tag, and download the Intel UHD Graphics driver. The Intel Core i3-N305 uses Intel UHD Graphics (32 EUs) that requires the correct platform-specific driver for HDMI output initialization. The generic Windows inbox driver may not support all HDMI output modes on this platform.
Fix 3 — Test with Different HDMI Cable and Port
Try a different HDMI cable rated for HDMI 2.0 or higher. If testing on a 4K or high refresh rate monitor, ensure the cable supports the required bandwidth. Also test the Latitude 3350 HDMI port with a different monitor to determine whether the monitor or the laptop port is the issue. HDMI cable failures are more common than port failures.
Fix 4 — Check BIOS Display Output Setting
Restart and press F2 to enter BIOS on the Latitude 3350. Navigate to Video > Primary Display. Ensure this is set to Auto or Intel UHD Graphics. If set to Switchable Graphics or a specific mode that does not include HDMI, the output may default to the internal display only.
“My Dell Latitude 3350 HDMI produced no signal on a classroom projector. Pressing Win + P and selecting Duplicate fixed it immediately — the display just needed to be told to project.” — Afiqah Zainab, secondary school teacher

Why is the Dell Latitude 3350 HDMI not outputting to an external monitor?
Common causes include Windows not detecting the display automatically, the Intel UHD Graphics driver needing an update, a faulty HDMI cable, or the BIOS primary display setting being misconfigured. Press Win + P to force display detection first, then update the Intel UHD driver from Dell Support if the issue persists.
What HDMI version does the Dell Latitude 3350 support?
The Dell Latitude 3350 with Intel Core i3-N305 supports HDMI 2.0 output, allowing resolutions up to 4K at 60 Hz on compatible monitors. Standard 1080p and 1440p monitors at 60 Hz or 75 Hz are fully supported. Verify your HDMI cable is rated for HDMI 2.0 for 4K connections.
Can the Dell Latitude 3350 run dual monitors via HDMI and USB-C simultaneously?
The Dell Latitude 3350 supports one external display via HDMI. If the model includes a USB-C port with DisplayPort Alt Mode, a second external display may be connected through USB-C. Combined, you can potentially run the internal display plus two external displays depending on the specific Latitude 3350 configuration.
Does the Dell Latitude 3350 support 4K monitors via HDMI?
Yes. With HDMI 2.0 and the Intel UHD Graphics driver correctly installed, the Latitude 3350 can output 4K (3840×2160) at 60 Hz. For 4K output, ensure you use a high-quality HDMI 2.0 cable, not an older HDMI 1.4 cable which limits resolution to 4K at 30 Hz.
