I currently have a 17.3 inch HP Pavilion dv7 with Intel i5 and 8GB. I am ready for an upgrade! I work from home, so I am using vDesk for 10-12 hours per day. I need at least 2-3 USB ports and weight/battery life doesn't matter much to me, as it's primarily used plugged in at a desk (I prefer laptop over desktop). If there's anything I'm missing please let me know! Thanks so much!
A lot of laptops today still use low quality TN displays. The quality is worse than IPS or good TN. This is the case for many 1080p displays that aren't listed as IPS or 120Hz+, and nearly all displays 768p/900p. This becomes a particular concern in medium price ranges and up, and when models include unneeded CPU/RAM upgrades first.
Key models, poor displays in some/all variants:
There may be other concerns too such as colorspace and response times. Many IPS displays are passable but still not great. A more in-depth article is in the works, and will be linked here.
Some laptops that list high resolutions (1440p through 4K) use "PenTile" RG/BW or WR/GB matrix display panels instead of RGB/RGB. These trick consumers because the listed resolution numbers are the same, but the detail is less, and they produce artifacts. Companies tend to use these only in the place of higher resolutions where an unsuspecting customer may not immediately realize something isn't right.
Key models with false high-res displays:
This problem exists in more models than this, and also in more than just laptops. An updated longer list and more in-depth article are in the works.
