<human>: Summarize the given text in a few sentences.

I went shopping for a TV from Best Buy (yup, that's my first mistake), and examining the models, picked a [LG 32LD450] since it seemed to be decently priced, had 4 HDMI ports, and several other connections, more than enough for his purposes. I considered the LG 32LD400, but that appeared to only have 2 HDMI inputs, and while it could work, would have required some daisy chaining I'd prefer to avoid.

This was based on some initial research I had done, but the final decision was done in store, after examining the display model above the tag.

Fast forward to today: he's happy about his gift, and I start setting it up. However, we realize the TV we got has only 2 HDMI ports, instead of 4 as expected. We double checked the model in store, and the model on the TV matches the box. We ended up with the correct TV model, but it definitely isn't what we wanted. Looking at LG's site, I'm guessing the display model was a [LG 32LD550] which is more expensive (I'd link to the Best Buy pages, but neither model is listed online). This wrong model was very deliberately placed over the sign for the TV I bought; there couldn't have been a mix up.

I'm intending to head to Best Buy tomorrow to return the TV, and I'm wondering if Reddit has any advice. I fully intend to check to see if the wrong model is still being displayed, confront them over it, and request to trade. Clearly they won't like that, and I'm willing to partially cover the difference, but after ruining the gift with shady practices, I have no intention of paying the full price for the higher model.

Are there any consumer protections laws regarding advertising that might help? I'm in Washington state if that helps.
