Update: I did some additional digging into the info for this portable monitor and finally found its specs buried deep in the product website: 800:1 contrast ratio 250 nits 72% sRGB So I guess it's basically just a lower quality panel... which probably explains the noticeable difference in color vibrancy.

Recently built a SFF gaming PC for travel, and ordered a 17.3" 1080p 144hz IPS portable monitor (Uperfect brand) from Amazon to pair with it... immediately noticed the colors were very different from the rest of my other displays. Seems a lot less vibrant. In my photo comparison example, on the left are my gaming laptop with 144hz IPS display, iPad Mini 4 and Samsung S23 Ultra, while on the right is the portable monitor. Notice that all the device displays on the left look more or less similiar in terms of color hue and intensity (they are all at default settings), while the portable monitor on the right looks noticeably different. This is after 2+ hours of tuning back and forth messing with all the monitor and calibration settings, the color still looks different from my other devices... still rather pale and washed out. I plan to use my laptop and the portable monitor side-by-side, so this difference in color and vibrancy is very noticeable and annoying. I know the china brand portable monitors can differ a lot in their quality... so I'm guessing either I got a dud unit or it's just a very low quality panel? Despite it being reviewed favourably and advertised as 100% sRGB and all. 🥴
