I'm trying to set up two TVs with my computer, but I'm running into some issues. My PC only has a single DisplayPort and a VGA output, which I'm currently using for a small monitor to make adjustments at eye level. The TVs I want to connect have HDMI inputs. I don't want to buy a new graphics card because that feels excessive. I've considered using a USB DisplayLink adapter like the WAVLINK USB to dual HDMI model, but I would prefer to have an extended desktop setup rather than mirroring the screens. I've tried a few simpler adapters, but they haven't performed well. Can someone offer advice on whether the adapter I mentioned would work or suggest any other solutions?

It sounds like you're hitting a bandwidth limit. USB 3.0 can struggle with higher resolutions and multiple screens because it only supports 5Gbps, and 4K at 60Hz needs over 14Gbps. For independent displays, you should look for a DisplayPort to dual HDMI adapter instead of a USB solution. That should give you better results.
Just to confirm, you're saying your TVs actually have HDMI ports, right? I've never seen TVs with DisplayPort. Note that standard splitters usually duplicate the same screen instead of extending it. If you want an extended setup, make sure to get the right type of splitter or adapter! Could you share a pic of your PC's outputs? That might help with suggesting the best option.
Oops, I mixed that up. They really just have HDMI. Here’s a photo of my PC outputs and the TV inputs: [link](https://imgur.com/a/9F0PLxk). Any ideas based on what you see?
Thanks for the tip! Just to clarify, would a DisplayPort to dual HDMI adapter extend the desktop across both TVs, or will it still mirror the output?
