| The screen shows good response rates in our tests, but may be too slow for competitive gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 36 % of all devices are better. This means that the measured response time is better than the average of all tested devices (20.9 ms). | ||

| The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 45 % of all devices are better. This means that the measured response time is similar to the average of all tested devices (32.8 ms). | ||
Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 21740 Hz | ≤ 20 % brightness setting |  |
The display backlight flickers at 21740 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 20 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 21740 Hz is quite high, so most users sensitive to PWM should not notice any flickering. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8715 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Skrivbordsdatorer för företag, inklusive allt-i-ett modeller, är en del av en marknad som är lättare att tolka än det packade och olikartade landskapet som råder för bärbara datorer av samma slag. Som av en händelse är det ingenting särskilt spännande med ThinkCentre M910z (vår konfiguration: ~ 10 500 SEK), som tar det säkra före det osäkra med en fungerande, underskattad design och bockar av alla krav för en traditionell kontorsmaskin.
Men det är inte något dåligt: i linje med sitt arv så får ThinkCentre jobbet gjort med en design som fokuserar på funktion framför form och levererar uppskattade funktioner såsom att den är (relativt) lätt att serva och uppgradera och har en pålitlig men stabil ledad design på sitt ställ. Den är också tyst (även under belastning), snabb för vanliga uppgifter tack vare sin fyrkärniga CPU och en NVMe SSD och har dessutom en uppsättning högtalare som motsäger den typiska dåliga prestandan hos sina syskon i samma företags-kategori och har bra ljud genom majoriteten av spektrat (efter lite justeringar). Skärmen ger blandade intryck. I huvudsak tack vare låg ljusstyrka och ett aningen frånstötande tryckkänslighetslager (som ställer frågan om huruvida köparen borde bry sig om ett tryckkänsligt gränssnitt när det i huvudsak är orsaken till den här bristen) - men den behåller åtminstone sin icke-bländade yta även när den är konfigurerad för tryckkänslighet! Tillslut, energiåtgången är behagligt låg, så den som överväger att placera ut en flotta av M910z-maskiner kan ta det lungt och veta att dom inte kommer att förstöra elräkningen.
Det finns inget särskilt intressant med ThinkCentre M910z, men det är inte något dåligt; den tar det säkra för det osäkra med en funktionell, underskattad design och bockar av alla krav för en traditionell kontorsmaskin.
I slutändan finns det inte något större negativt att förknippa med ThinkCentre M910z - det är en kapabel skrivbordsdator för arbete som - även om den är ointressant i sin design - täcker upp alla behov för företagsmarknaden och är så lätt att underhålla och använda att den borde finna stöd hos många IT-avdelningar.
