Why you can trust Tom's Hardware
The 559M1RYV has some stiff competition in the jumbo monitor category. For our comparison mdoels, we’ve rounded up a group of UHD 144Hz displays in the 43-inch size, along with the other Philips 55-incher, the 558M1RY. The 43 inchers are Asus’ XG43UQ and PG43UQ Acer’s CG437K and Aorus’ FV43U.
Pixel Response and Input Lag

The 43 inchers have a response advantage over the two Philips monitors with the expected 7-8ms draw time usually seen in 144Hz screens. The 11ms time isn’t surprising for the 120Hz Philips, but we expected a greater improvement from the 144Hz version. 10ms is still pretty quick and will deliver a responsive gaming experience with minimal motion blur. As we said earlier, the 559M1RYV’s overdrive isn’t aggressive enough, so you will still see some smearing when the action gets intense. Keeping frame rates high is key. You’ll want plenty of processing power to maintain speeds over 100fps. The 559M1RYV also has greater input lag than the rest. Casual gamers won’t see an issue (we didn’t) but skilled players may find a better experience with one of the other monitors.
VA screens are great for contrast, but their viewing angles are usually inferior to what you’ll find on IPS. This will be a factor if you plan to sit very close to the 559M1RYV. We recommend a viewing distance of five feet or more to avoid any perception of color or brightness shift. Our tests showed a red tint at 45 degrees horizontally and vertically. You can also see a reduction in depth and detail as the brightness steps lose definition. You can certainly share the screen from five feet back, though, which is important with a monitor this large.

Larger screens are typically less uniform than smaller ones. The two Philips monitors performed about the same in our tests, while the 43-inch monitors had slightly less deviation. Only the PG4UQ was free of visible artifacts. Our 559M1RYV sample was a tad hot in the corners when viewing a black field pattern. Higher brightness patterns and actual content looked fine. There was no edge bleed or blotchiness apparent.
