Review: Consigliato - Ottimo monitor preso in offerta. Per il gaming è spettacolare, uno dei pochi wide non curvi
Review: incroyable !!! - Le meilleur écran que j'ai pu tester, il est exceptionnel pour le prix !!! J'voulais absolument un écran avec une dalle IPS et au moins 144Hz et franchement j'suis bluffé par la qualité , même le packaging est de bonne facture, rien n'a été laissé au hasard , j'pense pas qu'on puisse trouver mieux dans cette fourchette de prix (entre 500 et 1000 Euros) La colorimétrie et les noirs sont profond le temps de réponse est parfait (même sur les jeux de tir compétitif sa change la vie tellement c'est nerveux) Par contre je ne le recommande pas si vous n'avez pas assez de place ou avec un bureau trop petit , car l'idéal c'est d'être à "MINIMUM" 1mètre de l'écran, sinon la tête bougera et la c'est pas bon du tout...

### ⭐⭐⭐⭐⭐ Amazing deal. ENABLE HDR!!
*by M***E on May 16, 2025*

A like-new condition 40-inch 144hz 1440p monitor with full USB type C docking for £307 was crazy, so even though I was initially in the market for something 2-3x that price I couldn't pass it up. It's a big monitor, intended to be used at a distance, which is perfect for me. The area is almost twice that of a 27 inch monitor. At this size I can read on-screen text without increasing the UI scale so there's tons of space for productivity. The biggest con is that the lack of curve causes the edges to appear slightly darker than the centre, but after a week this didn't bother me any more. The second biggest con is the typical LCD grey-like blacks, but for the price it's not a deal breaker. Enabling HDR is a must, and over USB C this will require the cable supplied in the box for the necessary bandwidth. This fixes the green-tinted and flat colours it otherwise has, and now I'm impressed with its warm, natural and vibrant colour presentation and strong brightness. Video and games really pop and look stunning, as you can see from my photo of Assassin's Creed Odyssey below. Even if its pixel response time figures fall behind other 144hz LCD monitors, motion looks good and plenty clear enough in person. Overall, super good deal and I'll be keeping this monitor for a while.
