I got my replacement screen back.
Two months of back and forth later and I’m basically back to where I’ve started. the replacement does not seem to be much different from the one I originally got back in December. So I guess my unit was not defective, but the panel they use just has bad colour uniformity.
To recap up what my issues are: colour is uneven (more red/yellowish in some areas, blue-ish in others) and hard to calibrate. Out of the box the display is super saturated and greenish. This problem is pretty consistent across the two I had so far. I’m coming from a 27" Dell display (UP2716D) which isn’t perfect either, but was definitely a lot better – even out of the box – than the Huion. We also have a Cintiq Pro here, and that one also has much better colours. As a reference, the Dell does cost about 800€ IIRC and of course the Cintiq Pro costs double the Huion. I guess they had to cut some corners to be able to offer the Kamvas pro for the price it has.
My experience with the customer support has been a bit of a mixed bag, but I would say more good than bad. The person who assisted me was generally kind and tried her best to help, but didn’t appear to be very prepared on the technical side of things.
There’s a few more details I’ve noticed in these 2 months of use:
- It has 2 USB ports, but these are only USB 2.0 and there are some power issues with them. Most hard drives I have tried to attach would spin down shortly after connecting.
- The OSD menu is pretty limited, but does allow to adjust basic things like brightness, contras saturation, and RGB. I found the AdobeRGB and sRGB presets pretty pointless, since they look too greenish.
- With MacOS I’m experiencing issues waking the display from sleep. It’s a common issue with some monitors on MacOS it seems. Sometimes it takes a really long time for the monitor to come back alive, other times it doesn’t come back at all, and I have turn it off and on again. When used together with another display, everything starts to flicker like hell when coming back from sleep, making a dual display configuration not very usable. I had issues with the XPpen Innovator 16 as well, when used together with the Dell display. Haven’t tried this on Windows yet.
UPDATE: I just found out that when switching the resolution to a 1.5x scaling factor the standby issues go away. MacOS is weird…
So my final verdict here is that the pen display is not suitable if you need colour accuracy. Expect noticeably uneven colours and hard to colour-calibrate display.
Other than that it’s not a bad device, it’s a 4K 24" (well more 23" I’d say) pen display, for half the price of a Cintiq pro, which has a lot of similar specs.
The pen seems to be good, has a laminated etched glass with minimal parallax, the viewing angle is pretty great and overall it feels like a good pen display.
Can’t comment on the tracking speed of the sensor, because my computer is a bit old. I get some lag (not a lot to be honest) but I think that’s mostly my computer not dealing well with the 4K resolution. It does get very laggy when I switch to a scaling other than the 2x one (scaled resolution of 1920x1080), and it also gets worse when using two displays.
