Display HDR Standard Announced: First Batch to Debut at CES2018

HDR, or High-Dynamic Range, was initially developed to improve a camera's ability to capture scenes with a wide range of brightness. However, in recent years, HDR has gained widespread adoption in notebooks, PC monitors, and smart TVs as consumers upgrade their devices and demand better screen resolution and image quality. With so much talk about HDR standards, it's worth asking: what exactly is an HDR standard, and how do common ones like HDR-10 or the proprietary Dolby Vision differ? To address this, the Video Electronics Standards Association (VESA) introduced the first HDR standard specifically for PC monitors—DisplayHDR. This new standard aims to provide clear benchmarks for manufacturers and consumers alike. According to VESA, DisplayHDR 1.0 is divided into three tiers: DisplayHDR 400, DisplayHDR 600, and DisplayHDR 1000. These levels are determined based on key display characteristics such as brightness, color gamut, color depth, and response time. The lowest tier, DisplayHDR 400, requires a minimum brightness of 400 nits, covers 95% of the ITU-R BT.709 color gamut, and supports 8-bit color depth. It also mandates support for HDR-10. Compared to traditional SDR displays, this level offers significantly higher brightness and improved color accuracy. The 8-bit panel ensures smoother gradients and better color transitions. Moving up, DisplayHDR 600 demands even higher performance: 600 nits of brightness, 99% ITU-R BT.709, and 90% DCI-P3 color coverage. This makes it ideal for more demanding content and professional use. Finally, DisplayHDR 1000 takes things even further with 1000 nits of brightness, making it suitable for high-end applications where detail and contrast are crucial. It’s important to note that all three tiers require true 8-bit panels, and the DisplayHDR certification applies only to LCD displays, not OLEDs. Additionally, while these displays meet the standard, they may not always be fully compatible with existing HDR content or games. VESA also announced that the first batch of DisplayHDR-certified products would be revealed at CES 2018, marking a significant step forward in the evolution of display technology. As HDR continues to grow in popularity, having a standardized benchmark will help ensure better performance and consistency across devices.

Power Meter Socket

Power Meter is a monitoring and testing instrument which determines the power consumption of a connected appliance and the cost of the electricity consumed.
Built-in 3.6V rechargeable Batteries ( . The purpose of the batteries is to store the total electricity and memory setting
Resetting
If an abnormal display appears or the buttons produce no response, the instrument must be reset. To do this,
press the RESET button.
Display Mode
Entire LCD can be displayed for about 1 minute and then it automatically gets into Model. To transfer from
one mode to the other, press the FUNCTION button.
Mode 1: Time/Watt/Cost Display Display duration(how long) this device connect to power source.LCD on first line shows 0:00 with first two figures mean minutes(2 figures will occur while occur at 10 min) and the rest shows seconds. After 60mins, it displays 0:00 again with first two numbers meas hour(2 figures will occur at 10hours)and the rest shows minutes. The rest can be done in the same manner which means after 24 hours, it will re-caculate. LCD on second line displays current power which ranges in 0.0W 〜 9999W. LCD on third line displays the current electricity costs which ranges in O.Ocost 〜 9999cost. It will keep on O.OOcost before setting rate without other figures.
Mode 2: Time/Cumulative electrical quantity Display Display duration(how long) this device connect to power source.
LCD on first line shows 0:00 with first two figures mean minutes(2 figures will occur while occur at 10 min) and the rest shows seconds. After 60mins, it displays 0:00 again with first two numbers meas hour(2 figures will occur at 10hours)and the rest shows minutes. The rest can be done in the same manner which
means after 24 hours, it will re-caculate. LCD on second line displays current cumulative electrical quantity which ranges in 0.000KWH 〜 9999KWH without other figures. LCD on third line displays"DAY"- "1 'Will be showed on numerical part(the other three figures will be showed at carry) which means it has cumulated electrical quantity for 24hours(one day). The rest can be done in the same manner untill the maximal cumulative time of 9999 days.
Mode 3: TimeA^bltage/Frequency Display LCD on first line displays the same as Mode 1 dones. LCD on second line displays current voltage supply (v) which ranges in 0.0V 〜 9999V .LCD on third line displays current frequency (HZ) which ranges in 0.0HZ 〜 9999Hz without other figures.
Mode 4: Time/Current/Power Factor Display LCD on first line displays the same as Mode 1 dones.LCD on second line displays load current which ranges in 0.0000A 〜 9999A. LCD on third line displays current power factor which ranges in 0.00PF 〜 LOOPF without other figures.
Mode 5:Time/Minimum Power Display LCD on first line displays the same as Mode 1 dones. LCD on
second line displays the minimum power which ranges in 0.0W 〜 9999W. LCD on third line displays character of "Lo" without other figures.
Mode 6: Time/Maximal Power Display LCD on first line displays the same as Mode 1 dones. LCD on second line displays the maximal power which ranges in 0.0W 〜 9999W. LCD on third line displays character of "Hi" without other figures.
Mode 7: Time/Price Display LCD on first line displays the same as Mode 1 dones. LCD on third line displays the cost which ranges in O.OOCOST/KWH 〜 99.99COST/KWH without other figures.
Overload Display: When the power socket connects the load over 3680W, LCD on second line displays the''OVERLOAD[ with booming noise to warn the users, (selectable choice)
Supplemental informations:
1: Except [OVERLOAD[ interface, LCD on first line display time in repitition within 24hours.
2: LCD on first line, second line or third line described in this intruction take section according to two black lines on LCD screen. Here it added for clarified purpose.
3. Mode 7 will directly occur while press down button "cost".
4. [UP"&"Down" are in no function under un-setting mode.
Setting Mode
1. Electricity price setting
After keeping COST button pressed lasting more than 3 seconds(LCD on third line display system defaults price, eg O.OOCOST/KWH ),the rendered content begins moving up and down which means that the device
has entered the setting mode. After that, press FUNCTION for swithing , then press "UP"and "DOWN" button again to set value which ranges in OO.OOCOST/KWH 〜 99.99COST/KWH. After setting all above, press COST to return to Mode7 or it will automatically return to Mode7 without any pressing after setting with data storage.
