Very nice!

I don't like the idea of creating multiple similar reviews, but I felt that since the same monitor is sold under slightly different names on Amazon, it may be appropriate to submit two similar reviews to help those who consider purchasing this monitor.Technology. There are several types of TFT LCD (thin film transistors liquid crystal display) technologies. The lowest-cost technology, TN (twisted nematic) which is used in all LCDs priced below $400 is known for its relatively poor color accuracy and color shift depending on the viewing angle. This is not critical for e-mails and document processing but is important for photo and video editing. These panels are typically built internally with only 6 bits per channel and physically cannot reproduce 24-bit color depth. Thanks to interpolation (dithering) and other hardware tricks they can approximate some of the colors and can reach up to 70% of the NTSC color gamut. The next step up is VA (vertical alignment) technology which reaches up to 100% of color gamut due to 8 bits per channel, but still has some color shift depending on viewing angle. The best and most expensive technology is IPS (in-plane switching). It offers the best color accuracy and practically no color shift dependence on the viewing angle. Partly due to problems with color shift caused by large difference in viewing angle between the center and the edges of the screen, 30" LCD displays are all made with IPS technology. This partly explains 2.5 - 3x price differential with TN-LCD 27". HP LP3065 uses S-IPS ("super-IPS") panel. The only flavor of IPS technology which is considered better than S-IPS is H-IPS. That one reaches 107% of NTSC color gamit and is found in professional monitors which cost several thousands of dollars, in some cases up to five thousands.The only disadvantage of higher end (VA and IPS) panels is a slower response time, typically 5 to 10 ms compared to 3-5 ms of TN panels. This makes no difference for office applications or graphics / photo editing but may have negative impact on gamers.Information on the internet. LP3065 was introduced in the late 2006 and was based on LG.Philips LCD panel LM300WQ1 which it shared with Dell Ultrasharp 3007. That panel had 300 cd/m2 brightness and 92% of the NTSC color gamut. Some time around 2008 HP changed its specifications to 370 cd/m2 and 102% of NTSC color gamut, which suggests that they may have upgraded their panel to LG.Philips LM300WQ5 which is also used in Dell's top of the line Ultrasharp 3008. However, model number did not change and there is a lot of confusion about it on the internet. Many of the tests and reviews were based on the early version of LP3065 with less advanced panel. In general, one should keep in mind that while there are up to 8 various 30" monitors on the market, they all share about 3 LCD panels produced by either LG.Philips or Samsung. The difference is mainly in the number of inputs (and associated electronics) and user interface.Inputs and resolution. The only type of input is dual-link DVI with 2560x1600 resolution (3 switchable input ports). This format is supported only by newer high end graphics cards. With single-link DVI, the monitor supports only 1280x800 resolution. There is no scaler chip inside, and therefore no other resolutions are natively supported. Standard analog VGA connector would not work. It is not possible to connect this monitor to a blue-ray player, playstation, etc. When computer boots up and shows BIOS configuration-related text, it is initially is displayed in 1280x800 which then becomes full resolution as Windows progresses with the boot up process. Since there is no scaler chip, there is also no on-screen user interface / menu. The only on-monitor adjustment is brightness. Everything else can only be adjusted through graphics card interface, but preferably should be set up during color calibration and never changed.There is a built-in USB hub with one input and 4 outputs. It works great for connection of keyboard and mouse. Since USB ports are all located on the left-hand side of the screen and are recessed by about an inch (so they are kind of on the back), access is not very convenient for "non-permanent" connections. One factor that simplifies access to the USB prots is that monitor can be turned on its stand by some 30 degrees in either direction without moving the stand or lifting the monitor.Fit and finish. Unlike nearly all other HP monitors which are glossy and reflective, this one has matte screen finish ("hard coating (3H) anti-glare treatment of the front polarizer", according to the LG.Philips panel spec). I find it great as you do not see reflections of objects behind you in the screen. It is a big heavy monitor which is tricky to assemble and move around by one person. The stand is steady, range of adjustments are more than adequate, and overall impression is solid.Colors. Monitors with this technology color accuracy MUST be color-calibrated in order to realize their advantages over cheaper TN LCDs. This can be done by using special software and colorimeters which are readily available starting from about $100, but the better one go for about $300. Any complaint in customer reviews about colors, color saturation, and color shifts should be discarded unless there is a clear statement that the monitor was calibrated prior to the assessment. My monitor had a color shift to greenish-cyan until I calibrated it. After calibration, the colors are excellent, the best I've ever seen on a computer screen. Our brain has some ability to do its own internal color correction, so one can get used to and not notice shifted colors, but once you load a calibrated color profile to a graphic card connected to a high-end monitor, the improvement compared to standard panels is quite impressive.Part numbers. Many resellers sell it as part EZ320A8#ABA, while specs on the HP web site are for EZ320A4#ABA. Neither HP pre-sales support nor technical support were able to answer the question about the difference, and could not even find A8 in their database. Interestingly, the monitor which I ordered directly from Amazon (it looks like Amazon sometimes sells it directly while in the other times leaves it up to independent companies) as A8 part in fact turned out to be the A4 part. Go figure.Overall impression. Very large, but not unreasonably large. Easy to get used to. Dot pitch is a little smaller than Ion 17", so the images on the web and text may appear to be on the small side. Colors are excellent after calibration. After I work for an hour with this new monitor and go back to my other computer with dual 17" Dell Ultrasharps, my first thoughts are: what tiny screens and how crappy are the colors! At full brightness, the screen is so bright that it hurts the eyes (interestingly, even at highest brightness the colors remain solid and clear, blacks are black, and contrast is excellent). I had to decrease the brightness almost all the way down to get it to the level which I got used to work with. So far, no regrets.

By Roenie
I will only add what hasn't already been mentioned by "+++" in his review. Some things he has said I just want to emphasize.-This monitor is a rare breed in that it can do it all, and do it so well. Gaming, photo/video work, watching movies... it is an OSD short of TFT perfection.-The LP3065 is fast enough for everyone except professional gamers. It's fast enough for (semi-) serious shooter amateurs and all round gamers. Faster than most other TFT's.-The inputlag (delay between mouse/keyboard input and the result showing on screen) is extremely low, because of the lack of internal image processing/buffering/OSD/color settings. I used to be a very serious, competitive gamer (Unreal Tournament) and I still notice quite a difference with a CRT. That's just the way this technology works, but you will likely not find a 24" or larger TFT with lower inputlag than this.-The dotpitch is very small, not recommended for those with bad eye sight, or if you like medium/large fonts.-For gaming, a 1920x1200 display is a better choice, because you will find yourself lowering the gfx details quite often just to be able to run 2560x1600, even on high end hardware. 1920x1200 is a much more sensible resolution, allowing you to enable FSAA and ultimately spend much less cash on upgrades.-I was expecting 1920x1200 displayed as is (1:1, not enlarged) to be nice to use, but due to the fine dotpitch of the 30" monitor, the effective diagonal of that resolution is approx. 22 inches, which is too smal for my liking. EXPECT TO BE FORCED TO RUN 2560x1600!!-Upscaled 1920x1200 does not look all that - this thing is huge and therefore you'll get a blurry image. Native resolution is where it's at.-1280x800 is 1/4th of native resolution and will show up crisp/sharp. For games, not recommended though due to severe loss of ingame gfx detail.-Power consumption, heating up the room, this thing gets HOT to the touch. Lowering the brightness (backlight) will save some energy.-This is a wide gamut display, therefore if you do ANY production work (photo, video, 3D, web,..) you must get your color management right.

Great Monitor but KVM Sucks
By Stilt Wiltafacation
Super-great picture. The KVM though is useless. I called tech support (HP's support SUCKS) and after escalating from the totally clueless person who answered, some guy from China told me you had to have identical graphics cards in both computers. What a joke! I asked him if he heard himself say that.Anyway, one of my cards died, so I bought an identical one (late model cards, late model computers running Win 7). No difference.Had to buy a $200 KVM.
