UPERFECT - UColor Q1 QLED Portable Monitor

Has anyone tried UPERFECT Q1 QLED Portable Monitor - 15.6" Travel Monitor 1080P? I have it but it give me a headache and is kind of blurry. Does anyone know a portable monior that will not do this? Looking for one that I can read an email or PDF from which will be very clear and not give me a headache haha

I currently have a cheap 15.6 UPERFECT portable monitor which works fine, but I'm wondering if there are any cheap portable monitors around that same size that don't need to be plugged into a battery bank? I've seen portable monitors with built in batteries which is cool, but are above my preferred price range ($100). Maybe something slightly smaller? I really just use Dex on my couch on a lap desk for basic productivity (email, WhatsApp, Google Docs and Sheets, etc.) so pretty 4k HDR specs aren't necessary. Trying to optimize set up and have the least number of cords possible. For reference, I'm running my Dex setup off of a Samsung Galaxy S23 Plus Thanks in advance! UPDATE: Thanks so much everyone for the input! I ended up purchasing the same cheap portable monitor as u/Franky_Mars & u/TheWalkingZen (KYY Portable Monitor) and it arrived this morning (Amazon ftw), and it's exactly what I needed. The 50% brightness is fine for working while on the couch in short spurts and was in my price range. Maybe I can convince my wife to let me get them fancy XREALs or a Sotsu monitor one day when our kids aren't burning holes in our wallets!

I used a uperfect usb c monitor for about a minute and it worked. I don't know more than that as the monitor had a fault and I'm waiting on a replacement. I'd choose on Ali express, the 16inch 120hz portable OLED or the 13 inch 1080p 60hz OLED at around £200 and £100.

I recommend the UPEFECT. I use mine for my ROG Ally and Samsung Dex setups.
