Discussion NVIDIA QUADRO P620 V2 which does not display on External TVs but on normal monitors it displays on all 4 ports.

[@sirgeo]

This is installed on Windows 64-bit system. What is confusing is the display is okay on normal monitor up to 24". But on bigger TVs like 52" the display says WEAK Signal. I have tried to connect HDMI to an on board HDMI port with positive results. But connecting to any port of the add on NVIDIA QUADRO, I fail to get a display. Please help. All necessary drivers are installed. Why should I fail to get display on bigger monitors if I can get display on small and ordinary computer monitors

What length cable are you using to connect to the TV?

3meters. But still it displays on small monitor

Is this a mini-DP to HDMI cable, or are you using an adapter ?

HDMI cable connected to one of the 4 ports of the NVIDIA QUADRO P620 V2

The ports on the card are mini-DP. So the cable must convert. It could be a poor quality cable.
Maybe get a separate mini-DP to HDMI adapter and a regular HDMI cable.

In addition to the above it may also be that the television doesn't support the specific signal being provided by the card. Check the television's user manual for the timing specs.
