My Notes Shopping For A New Desktop Monitor

My Samsung T260 25.5 inch LCD monitor malfunctioned on Aug 2018. The monitor displayed poor quality images; however, there was a smell from the rear vents. I purchased the T260 for $450 on Dec 2008.

My new monitor is a Samsung U28E590D 28 inch UHD 4K monitor. I purchased the E590D on Black Friday 2018 for $250.

I want to share my research notes to help anyone shopping for a new monitor.

*First check. Confirm your desktop's graphics card can display 4K or 3840x2160 resolution if the user wants a 4K monitor.

*Minimum monitor size is 27 inches for 4K. Minimum monitor size is 24 inches for FHD or 1920x1080 resolution or 1080p.

*Monitors with tilt adjustment and/or height adjustment are advantages. My E590D has a tilt adjustment.

*Thin bezels are attractive.

*G-Sync technology is for Nvidia graphics cards. Free Sync is for Radeon graphics cards. G-Sync and Free Sync are Adaptive Sync technology. They eliminate screen tearing on a visual artifact when a monitor displays multiple frames at once. It occurs when the number of frames is sent to the display. Refresh rate is not a factor.

*Latency or response time 5ms or less is good.

*27 inch or greater recommended for curve monitors.

*IPS stands for in-plane switching. PLS stands for plane-line switching. IPS and PLS are the same for most users. The differences are for specific needs such as gaming or color-critical work deeper blacks and accurate colors.

*PPI stands for pixels per inch. Horizontal pixels divided by vertical pixels. The higher the PPI, the smaller the pixel pitch.

*HD or 720p is 1280x720. FHD or 1080p resolution is 1920x1080 16:9. WQHD or 2K resolution is 2560x1440 16:9; also called WideQuad or QuadHD or QHD. 2K cinema is 2048x1080. UWQHD is 3440x1440 16:10; also called Ultra WideQuad. UHD or 4K is 3840x2160 21:9. 4K cinema is 4096x2160. 5K is 5120x2880. 4K means four times shaper than 1080p.

*sRGB is 90% of NTSC. sRGB for Adobe RGB settings are 5,000-7,000 color temperatures and 1.8-2.4 gamma presents.

*LED is better than LCD. There are LCD monitors in the market. LCD have better backlighting. OLED or Organic LED is the latest visual display technology.

*HDMI cable carries both video and audio. A 4K UHD the video is 30 frames per second or 30fps.

*Display Port cable carries both video and audio, too. The video is high resolutions and high frame rates. A 4K UHD the video is 60 frames per second or 60fps.

*Refresh rate is times per second the monitor updates the image. A 120Hz display refreshes the image 120 times per second. The higher refresh rate, the smoother movements any actions appear. 60Hz is good for most users.

*Twisted Nematic or TN is worse than in-plane switching or IPS which has better colors and best view at most angels. Vertical Alignment or VA is not the same as IPS. VA has better contrast and better image depth.

*Brightness is measured as cd/m^2 or nits. 200 nits is good. 300 nits is brighter for better colors and contrast.

*24bit color display 16.7 million colors. 24bit is good for most users.

*Watch 4K videos on YouTube to test a 4K monitor display.

*Always shop around. If you can wait to buy a new monitor, then wait. Prices go down in time. For example, a Samsung 28 inch 4K LED monitor was $580 in Jan 2015. I watched a YouTube video on my new monitor. The person on the video dated 2016 paid $400. I paid $250 for my Samsung 28 inch 4K LED monitor in Nov 2018.
