Seconding the recommendation above! Sanus is honestly the way to go if you want zero stress with those weirdly placed Sony ports. I actually just finished mounting a Sony 75 Inch X90L Series 4K Ultra HD TV in my living room and went through this exact same struggle lol. The thing with Sony is that their VESA holes are sometimes lower on the chassis than other brands, which can make the TV sit higher than you expected. Plus, that back panel bump is a real pain! I ended up using the Sanus VLF728-B2 Full-Motion Wall Mount for my big set. It is definitely more expensive, but the build quality is insane and it comes with a huge variety of spacers that saved my life... basically made sure I could still reach the HDMI 2.1 ports for my PS5. For your smaller 43-inch guest room set, you dont need to spend that much. I suggest checking out these:

• Echogear Full Motion TV Wall Mount EGLF2
• This thing is amazing for the price and super sturdy for mid-sized sets.
• Sanus VLT7-B2 Advanced Tilt 4D Wall Mount
• If you just want tilt, this is fantastic because it lets you pull the TV away from the wall a few inches to reach those side-facing ports without taking the whole thing down. One technical tip: always check the bolt length! Sony sometimes needs M6 or M8 bolts that are slightly longer than what comes in the cheapo generic kits, but the brands mentioned earlier usually include the right ones in the box. Tbh, spending the extra cash on a high-quality mount for a premium TV like the X90L is just a smart long-term investment. gl with the installation!

Check out Monoprice Commercial Series Full Motion Articulating TV Wall Mount if ur looking to save cash. It's usually under $55 and seriously sturdy for big screens. Pro tip: use the MountingHeight website tool... it's a lifesaver for getting the placement right. I've been doing this for years and safety is everything, so basically just make sure u hit the studs. It's way cheaper than Sanus but still super reliable. gl!

In my experience, i totally get the port layout struggle!! > My main concern is ensuring the mount doesn't block the specific port layouts Sony uses sony ports are weirdly placed lol. i have two sony bravias and sanus or echogear worked for me cuz they include spacers... basically prevents blocking anything. for that huge 75-inch, i'd go with their full-motion ones. have u checked the weight on that model? anyway, those brands worked for me. gl!
