HP 2311xi IPS Monitor
by Chris Heinonen on August 13, 2012 12:15 AM ESTHP 2311xi - Input Lag and Power Use
One area where the 2311xi does much better than its budget price would indicate is in our lag testing. Input lag ranged from 1-3ms on testing, showing very little delay at all. The response time from blue to yellow to blue was only around 20-22ms as well, giving us a total lag result of 13ms. This is a decent amount under 1 frame of lag and should be adequate for even demanding users, and this was with the Overdrive feature disabled. Overdrive being enabled made no noticeable difference with lag or delay time, but might help slightly with blurring. Overall these are some very impressive numbers for the gamers out there who might be considering using this panel.
Power use on the 2311xi was a high point as well. With the backlight at maximum it uses a miserly 26W of power, and that drops down to 12W at minimum levels. Finding a monitor that uses less power than this might be possible, but you will likely only save a watt or two over the HP. All the examples in our database that use less are either smaller panels, or TN panels instead of IPS. There is nothing I can complain about with the power usage of the HP 2311xi; it does fantastic here.

Sorry, but a 16:9 monitor? Great for a TV, but not for a general purpose computer.kyuu - Monday, August 13, 2012 - link
And here I was hoping we'd get one monitor review without 16:10 snobs popping up...seapeople - Monday, August 13, 2012 - link
Ok, then go buy the 1200p monitor for the same price.Oh wait.
You can't.

I guess I might have googled it, but I wonder why it is not mentioned anywhere? Are there really no other panels than 60Hz nowadays?I am working now on old 19" ThinkVision (excellent LCD, with 75Hz refresh) and 60 to 75 makes difference.

Yep, monitors are 60Hz pretty much exclusively nowadays, unless you're looking at monitors meant for 3D that do 120Hz.cheinonen - Monday, August 13, 2012 - link
Unless it is mentioned, I would assume 60Hz for a refresh rate. With the use of an HDMI input, and not specifically being an HDMI input that supports beyond 1080p, it's likely the internal electronics only support a 60Hz input anyway, even if the panel could support higher.Jumangi - Monday, August 13, 2012 - link
Bestbuy has this on sale for $169. Yea its got compramises but for that price the basic display you get is a darn good deal.jaydee - Monday, August 13, 2012 - link

I think this is a good idea. How about putting together a round up of displays so it is easier to compare their pluses and minuses?mikato - Thursday, August 16, 2012 - link
+1IPS monitor roundup! There are so many people out there with their eye on IPS monitors, but since they cost a bit more, these people are careful and do their research. They would definitely like a roundup like this.
