To determine which Peak & Hold you need
- Grab a multi-meter and select Ohms 200
- Touch the positive and negative leads of multi-meter together to measure resistance (record this number...i.e. measured 0.3)
- Then take the positive and negative leads from multi-meter and put on each terminal of the injector. Doesn't matter the order. Record this measurement
- Take the ohms measurement from Step 3 and then subtract the number you got in Step 2 (i.e. Step 3 4.8ohms - Step 2 0.3ohms = Total 4.5ohms)
High Impedance Injectors - Above 7ohms - No Peak and Hold Boxes are needed.
Peak and Hold 2A - 3ohms to 7ohms (Bosch 160lb/hr).
Peak and Hold 4A - Below 3ohms to 1.5ohms.
Peak and Hold 8A - Below 1.5ohms (Billet Atomizer*).
All low impedance Billet Atomizer Injectors manufactured after Nov. 2012 require 8A regardless of measured resistance.
*Billet Atomizer Injectors - Anything prior to serial # C300**** should only use the 4A/1A. This only applies to injectors manufactured prior to Nov. 2012.

Excellent monitor!!! Be aware that it does not have internal speakers.
Size: 24 inch 100Hz
Beautiful image. This monitor is excellent and I am very happy with it.
However, you should be aware that it does not have any internal speakers and it does not have any audio input. It does have audio output for external speakers or headphones. For me, this was not a problem since I use a USB external speaker for better clarity.
The lack of internal speakers was a surprise to me, but I suppose since the lack of speakers mentioned in the product description should have tipped me off.

Works as it should
Size: 24 inch 100Hz
I started a new job a few months ago and I get to work from home one day a week. They do not pay for you to set up a home office however, so I was looking for a cheap monitor for part of my set up. I came across this one and decided to try it out.
I work in client service for a finance company so a lot of what I use it for is email, other conversational programs, and then our custodian software. I’m not doing anything crazy. I have it connected to a name brand laptop and it was very easy to set up with no issues. It turned right on.
The picture quality is nice. Again, I’m not doing editing or anything on this so it works for what I need. It does NOT have speakers, so I do need to use the speakers on my laptop( which can be annoying), but again it’s not a deal breaker.
I have been using it now for 5 months and it’s been working really well for my set up. I am thinking of getting a second monitor and I would get another of these but also I do want a speaker so I don’t know that I would get this exact version.
For the price, if you are looking for something basic for normal work from home needs, this does the trick!

pretty good
Size: 24 inch 100Hz
Philips' 24-inch Frameless Full HD Monitor has the same type of attraction that the sleek lines and frameless edge provide as the utility that the product provides in terms of work and entertainment. Frameless edge helps provide the fashionable and streamlined appearance, while the 23.8-inch display provides the Full HD (1920x1080) resolution that creates the crisp images that are ideal for daily usage.
Establishment and Link:
Installation of the monitor is usually simple and easy, and the process is not difficult to complete and comprehend by the user. It includes one HDMI and one VGA socket in order to support most equipment. It lacks internal speakers, yet external speakers or headphones must be utilized if one desires sound output from the monitor.
Performance
It has the feature of supporting up to 100Hz display refreshes for smoother graphics when doing regular computing tasks. While good enough for general applications, there were comments that said that accurate color calibration to function is problematic and that this is one area that needs investigating if you're doing high accuracy color precision tasks.
These include:
A. Design
Aside from the frameless feature, the monitor also impresses by being light in weight and having a sturdy base. The stand itself is also adjustable so the user has the opportunity to tilt to the convenience. VESA mounting support is also included on the monitor for the convenience of the user who would want varied mounting options. Reddit
Conclusion
Philips 24-inch Frameless Full HD Monitor offers the perfect form and function blend at the unbeatable price. Easy installation, two ports for connection, and the slim profile make it perfect for those consumers who require a no-frills monitor for general computing use. Purchasers will have to balance the fact that there are no speakers built-in and potential differences in the accuracy of the color calibration to decide if the display is perfect for their specific requirements.
