HDMI for Dell Inspiron 3000 series w/ Windows 10

just found out from Dell that my HDMI port is IN only.....

 

display port to hdmi no signal

Do you have the latest drivers installed for the graphics card?

If new drivers or reloading graphics card drivers doesn't fix it, the next thing I would suggest is to try the display port to HDMI adapter a couple of us have suggested already with a regular HDMI cable. If your cable is bad or you just need an adapter because for some reason a straight cable won't work - spending $20 on the adapter is a lot cheaper than new graphics card. I just installed my GTX 970 card a week ago and I had plenty of HDMI cables so that is why I went with the adapter instead of buying a new display port to hdmi cable.

 

LG TV HDMI output doesn't work for specific Dell computers

Hi

Welcome to Microsoft community.

It seems like you are experiencing compatibility issues between certain Dell laptop models (Latitude 5430 and 5440) and your LG TV (model 65UK7500PJA) when using HDMI. While it's challenging to pinpoint the exact cause without detailed hardware and software analysis, there are a few possible reasons and steps you can take to troubleshoot and potentially resolve the problem:

1. HDMI Cable and Port: Ensure that you are using a high-quality HDMI cable and try different HDMI ports on the LG TV. Sometimes, specific HDMI ports on the TV may have compatibility issues with certain devices.
   
2. Resolution and Refresh Rate: Verify that the resolution and refresh rate settings on the Dell laptops are compatible with the LG TV. Lower the resolution and refresh rate on the Dell laptops to the native resolution and refresh rate of the TV to check if that resolves the issue.
   
3. HDMI Output Settings on Dell Laptops: Some laptops allow you to customize the HDMI output settings. Check the display settings on the Dell laptops to ensure they are set to duplicate or extend the display to the external monitor (TV).
   
4. HDCP (High-bandwidth Digital Content Protection): HDCP is a copy-protection feature used in HDMI connections. It's possible that the newer Dell laptops are using a different version of HDCP that is not compatible with the LG TV. In this case, check for firmware updates for your TV that might address HDCP compatibility.
   
5. Different HDMI Standard: Newer Dell laptops might be using a different HDMI standard (e.g., HDMI 2.0) than the older models (e.g., HDMI 1.4). Ensure that both your LG TV and Dell laptops support the same HDMI standard.
   

Please feel free to let me know if you have any further updates, thanks.
