The S517 offers a pleasant PC monitor experience not only due to the good responsiveness but also because of the video signal's compression.
The TV won't make text appear blurry while connected to a PC because the signal has no compression and transports color data and luminance fully. This is also known as chroma 4:4:4, and the “Computer” and “Game” modes display it properly at 60Hz.
Pro Accessible inputs

Pro Optional video smoothing feature
The S517 offers the possibility to represent motion in videos smoother, also known as the "soap opera effect".

The frame rate can interpolate up to 60 frames per second.
Pro Handles 4K scaling well
The S517 does a reasonably good job with upscaling most content to 4K quality, be it 480p DVDs, HDTV or full HD Blu-rays.

Pro Good HDR playback
The S517 is a much better fit for HDR content and HDR gaming than its competitors due to the wide color gamut, decent color depth, and high contrast.
The TV can display a lot more colors than its similarly-priced counterparts. The coverage of the Digital Cinema P3 color space is very good - 90%.
The color depth is on par with competing options. The S517 has 10-bit color depth, which means that it can display approximately 1.07 billion colors in total. This is important for HDR content because HDR media takes advantage of 10-bit.

They enhance the viewing experience by editing the metadata, that is, the extra information that tells the TV how to display HDR. The formats differ in the way they deal with it, however - Dolby Vision edits the picture on a per scene basis, whereas HDR10 edits everything at the start of the video.

The S517 has superb black uniformity and contrast that create pleasant, deep blacks. They are much better than those of the similarly-priced competitors. The maximum deviation sits at around 1.02% .
The TV is good at capturing small differences in color such as skin tones, green colors in nature, details in shadows, etc. This is because of the color gradient, which is on par with other options of the same price. There is almost no banding and the standard deviation of color doesn't go past 0,11%.
Con Doesn't work well in a bright room

Con Doesn't support 4K
You will not be able to play native 4K media on this TV because of its low resolution.
Con Can't overcome glare
The S517 is a better fit for dim environments or dark room viewing since the brightness can’t peak very high, only at 277 nits. This is common for TVs in this price range.
Con Runs ads
The main interface page contains big advertisements that can’t be disabled.
There’s also a “Featured” tab that promotes all kinds of apps and channels.
Con Some dirty screen effect is present
This might cause some discomfort to sports fans because the playing surface might look darker at points. The S517's gray uniformity is decent at best, which, unfortunately, is often the case for lower-end TVs. The image is a little darker around the edges and the middle of the TV. The standard deviation of sits at around 3.1%
Con Inconvenient calibration access
The only way to access the calibration menu is via the mobile app. This might be uncomfortable for people without smartphones or for people who prefer all control on the real remote.
Con HDR content lacks brightness
Small bright details in dark scenes won’t stand out. Unfortunately, this is usually the case with TVs in this price range. The TV's brightness for HDR media peaks at only 273 nits. Moreover, the TV doesn't support local dimming, which is also a big drawback for HDR content.
Con Struggles with reflections
While the S517 is okay for dimmer environments, the weakness shows in bright rooms and especially rooms with the light source facing the TV. The reflection handling of the TV is a bit worse than that of its competitors. It reflects approximately 6% of light off the screen.
Con Bad viewing angle
The S517 is a bad choice for a wide room because colors and blacks shift when viewed even slightly off center.
Leaning sideward just a little bit will drastically alter what you see. Colors shift at 18 degrees, brightness shifts at 28 degrees, but the blacks shift at the incredibly tiny angle of 9 degrees.
