There are 5 good budget options: The BenQ Zowie XL2411 (back-light strobing), LG 24GM79G (Free-Sync & strobing), MSI G24C (Free-Sync & VA panel), Samsung C24FG70/73 (Free-Sync, strobing and VA panel) and Viewsonic XG2401 (Free-Sync). The rest of the tested budget options are significantly worse.
The LG and Viewsonic (best) have the best image quality of the TN panels while the Samsung (VA panel) easily has the best image quality of them all, but the worst overdrive since it suffers from green and purple overshoot ghosting during fast black, brown and grey transitions. TN panels have dulled and vertically uneven colors (vertical gamma shift) and very restrictive viewing angles.
VA have more vibrant and even colors, tipple the contrast or 3 dark black depth and far less restrictive viewing angles than TN panels which allow them to be raised and viewed when leaning back while TN panels must be viewed like this to not look awful. The Samsung is more accurate and vibrant (use the sRGB mode to prevent minor over-salutation) than the MSI which suffers from more dark black, brown and grey color smearing, but less over-shoot ghosting.
