This thread isn't about why laptop screens are unsuitable for trading in terms of screen space. Obviously the desktop monitor would win out in screen real estate. BUT rather, thread is about looking at just one chart either on laptop or desktop monitor. This is my experience with a Dell Inspiron laptop circa 2007 (14 inch at 1440x900) vs Lenovo desktop monitor circa 2020 (21.5 inch at 1920x1080). To sum it up, my the Lenovo monitor sucks: I have never seen a laptop with buttons to change the contrast. All you gotta do is deal with the brightness and trust that the OEM properly calibrated the screen and that is that. My laptop screen circa 2007 (TN 14 inch at 1440x900) seems pretty high end even by today's standards. The comparable desktop monitor with similar pixel dot pitch would be a 21.5 inch QHD monitor. Mind blown! Now back to the Lenovo desktop IPS monitor: Wow does it suck! When I first connected it to PC, things seemed a little blurry. I only noticed something wrong when I looked at a chart with white background. The colors inside the candlesticks seem to spill out onto the surroundings! BUT a quick factory reset within the monitor menu fixed that. Then, I noticed a few things in the monitor menu. Factory default is red shift. WTF!! There's normal mode, blue shift, red shift, and sRGB mode. Putting monitor in sRGB mode hurt my eyes. Why I gotta deal with contrast and color shift mode in addition to brightness on a desktop monitor just to have it look okay. Whereas I only need to deal with brightness on a laptop screen. BUT the end result, the chart on a desktop monitor looks worse than on a laptop screen and I have missed quite a few trades had I chose to do my analysis on the laptop instead!
