Aorus Fi27q-x. I use a PC, so I have no use for hooking up a TV as a monitor. I mean, that's the entire point of having a monitor. If I wanted to use my TV, I would be using the PlayStation or Xbox.
TVs have been very good gaming displays for some time. I use a 42" LG C3 OLED, and I find Filmmaker mode solves 99% of the type of problems you're talking about. The tone mapping setting works very well on this display, it in itself is a game changer. It's also not at all true that TVs only work well with, or are primarily used with consoles. A lot of people with top shelf gaming PCs use high end TVs for gaming on them.
Another thing that can make a big difference is proper room lighting. If you have a dark panel TV, it's best to use dark room lighting, preferably a behind the display bias lighting kit. I got mine for only $12 and it is very good. It's dimmable and it is bright white light in the 4k color spectrum, so colors look realistic and accurate. If any of your room lighting is in front of your display, that might be part of the problem.
I'm not saying my TV is the best example, not by far, but your display has just an IPS panel, which are known to be a dark panel. OLEDs are too, but since LG tweaked them with EVO tech, they are brighter now, and Filmmaker mode if you don't have it is a real problem, especially on a dark panel. My last Panasonic display was an IPS, so I know what you are going through. Trust me, I used to go through it too.
Samsung's QLED TVs are very bright OLEDs, yet retain the sharp contrast of OLED. They are pretty expensive though and don't come in smaller sizes like 42", or I would have seriously considered one.
This is similar to the light kit I bought, except mine is just white, not color changeable. At the time I bought mine, many were saying they didn't get the dongle and remote the kits are supposed to come with, and you can't turn it on or off or dim without it. Mine didn't either, but then I emailed Power Practical, the company that sells them on Amazon, and they sent me a remote and dongle.
