HD on computers predates TV HD and 16:9 only arrived as a cost reduction to Computer monitors MUCH later.
16:9 is pretty useless if you need reading glasses, as with a 26cm screen height and normal viewing distance it's too wide. Yet putting the task/quick launch bar at side would help. That DOES work on XP. Mac OS, Windows, Linux by default have it at the bottom, stupid in Landscape WS. Also Portrait mode is rarer on desktop computers now than high end workstations 1980s to 1990s, though used on advert screens. Most graphics cards support it. Amazingly given how primitive it is, Android does have the quick launch at the side in Landscape, though stupidly only allows notifications at top.
You can get high end laptops from Lenovo with better than 1920 x 1200 screens.
Also 1080 (rather than 1200 turns out to be JUST too short for A4 documents in portrait). A 4:3 format 2060 x 1545 approx screen at about 200 dpi (without sub pixel addressing) would be a decent minimum. My 14 year old laptop is 133 dpi and 1600 x 1200. The 133 dpi is a little low for good fonts, only "saved" by the fact that the sub pixel addressing works and gives text closer to an effective 250dpi horizontally. More modern screens have a more complex structure requiring two lines for averaging of the colour sub pixels so work badly with sub pixel addressing

or some other variation.
The so called "retina" screens may use four lines to repeat the pattern, but they don't need sub pixel addressing.
The subpixel address is a slight misnomer as the RGB pixels are not actually addressed, instead the black text has coloured edges, based on assumptions of how the colour is laid out on the panel. Windows from XP onwards has a separate fine tuning utility to adjust appearance of text (cleartype). Linux has such a utility included on most desktop's control panels.
Even for a 7" tablet you want an IPS. The cheap laptop and tablet screens are worse colour and viewing angle than my 14 year old CCFL backlit LCD.
Not all LED backlights are good.
OLED etc look good on a phone or tablet, but they are short life as they are really EL panels, not true LEDs.
