Since a couple of years ago, I spent a year or so like this, with the TV resting on the desk directly.
It looked pretty nice, but it had some problems.
- The only actual 8K modes reported on the HDMI were some variant of YUV, it means you could not select what your OS considered an RGB mode
- Even using it at 4K, with the 55" TV a couple of feet from the back of the desk, my eyes could not keep all of it perfectly in focus.
- The power consumption was much higher than a typical ~30" monitor, and the amount of heat created was also significant. This became hard to deal with in summer.
Eventually I gave up on it and returned to a ~30" monitor.
