En 30 secondes
Une couverture colorimétrique de malade une fois calibré, mais la fiabilité aléatoire et l'absence de KVM fonctionnel gâchent la fête. Achetez-le seulement si vous avez une sonde et de la patience.
Avantages et inconvénients

Les preuves
Performances
Ce qui surprend, c'est que malgré des specs de colorimétrie haut de gamme (94e percentile chez nous), la calibration d'usine laisse à désirer. Beaucoup d'unités affichent une dominante rouge en sortie de boîte, ce qui oblige à passer par une sonde pour exploiter vraiment le potentiel du moniteur. Et le DisplayHDR 400, on en rit presque : le HDR est quasi inexistant. Par contre, une fois calibré, le rendu des couleurs est juste somptueux pour la retouche photo.

Face à la concurrence
Si vous voulez du gaming haute fréquence, ce Lenovo n'a rien à faire ici : un ASUS ROG Strix XG27UCDMG avec sa dalle OLED 4K 240 Hz sera autrement plus réactif, tout comme le LG UltraGear 45GX950A-B ou le MSI MAG 271QPX QD-OLED E2. Pour les créatifs, le véritable rival reste le Dell UltraSharp U4025QW, un écran 5K2K ultra-wide au calibrage usine irréprochable, mais bien plus cher. Le Lenovo reste une alternative correcte si votre budget est serré et que vous acceptez de bricoler les réglages.

Prix
Rapport qualité-prix
Aux alentours de 500 € chez Best Buy, le P27u-20 devient un écran 4K équilibré pour les photographes qui ont déjà une sonde. Mais gare aux tarifs aberrants qu'on voit parfois grimper au-delà de 20 000 € chez d'autres vendeurs (oui, vous avez bien lu). Si vous dépassez 600 €, passez votre chemin et visez plutôt un Dell UltraSharp mieux calibré.

Aperçu
Le Lenovo ThinkVision P27u-20 promet tout pour les créatifs : un écran 4K IPS de 27 pouces, une couverture Adobe RGB de 99,5 % et une connectivité Thunderbolt 4 avec hub intégré. Sur le papier, c'est le moniteur rêvé pour l'édition photo et la productivité, livré avec un support ergonomique complet et un tas de ports. Dommage que l'expérience réelle dépende autant de votre chance à la loterie du contrôle qualité.
Questions fréquentes
Q: Est-ce que ce moniteur a une webcam intégrée ?
Non, et c'est un oubli vraiment dommage pour un écran qui vise le télétravail. Tu devras passer par une webcam externe, c'est le deal.
Q: Le HDR est-il convaincant ?
Franchement, le DisplayHDR 400 c'est du marketing pur. Le rendu HDR est à peine perceptible. Si tu cherches un vrai HDR lumineux, passe ton chemin.
Q: Ce moniteur est-il bon pour la retouche photo ?
Oui, ses 99,5 % Adobe RGB en font un outil super précis. Mais prévois une sonde de calibration, car la couleur sortie d'usine est souvent trop chaude.
À qui ce produit ne convient pas
Si tu as besoin d'un switch KVM fiable pour jongler entre plusieurs PC, ce Lenovo n'est pas pour toi. Les Dell UltraSharp gèrent ça bien mieux. Et les joueurs, oubliez : 60 Hz et 4 ms, c'est trop juste, partez sur un écran OLED 240 Hz comme l'ASUS ROG Strix XG27UCDMG ou le Samsung Odyssey G60SD.
Verdict
Le ThinkVision P27u-20 est un excellent moniteur… à condition de mettre la main sur un exemplaire sans défaut et de posséder un colorimètre. Si vous êtes photographe et que vous le trouvez autour de 500 €, foncez, mais ne comptez pas sur le KVM ni sur le HDR. Pour tous les autres, il y a mieux ailleurs.
