HP LP2475w, IPS 24" Official Thread! (Now Available from OcUK)

That got me thinking, what could be different about people's set up that would make such a difference to the output. I also remembered reading somewhere that the uneveness may be down to a low quality DC converter on the backlight. Then it clicked - what can upset sensitive electronics? Magnets. What has magents in them? Speakers. What do a lot of people (but not all - particularly pro reviewers) have either side of their monitor? Yep, speakers.

Hmmm, interesting... I have both my Logitech speakers on either side of the screen with just a few millimetres between them and the frame, and the subwoofer is just to the immediate right of that but I've not seen this issue... yet.

My speakers and subwoofer are shielded though as you'd expect from PC speakers these days so unless people are using very old unshielded speakers I wouldn't expect them to be the cause of this issue really.
 
Interestingly users of the Philips 240PW9EB or ES (Black/Silver casing) are reporting exactly the same tinting issues with their monitors and this uses the same panel as the HP. Maybe there's some issue with LG's production run of these?

Whilst moving all magnetic sources has improved things I'm still now RMA'ing the HP as the effect it has on grey or yellow backgrounds is not acceptable. To Overclockers credit they are handling this promptly and properly.

@mrk - I notice from another thread you have experience of the Hazro HZ26Wi - Would you recommend this screen as an alternative. A supplier is getting some final stock of the rev 2.1 screen.

If not what suggestions would people have for a decent (preferably problem free) 1920 x 1200 res screen. Only one I can find in this price range is the Eizo S2242W (I don't want a dell and the NEC 2490 is too expensive).

Thanks all

I've not used the 26" Hazro myself so could not say but I do have the 24" (latest firmware) and with glossy panel and cannot recommend it enough BUT others have had problems with green lines and Power Supply issues. Hopefully they get them fixed as I had my first revision swapped out for a fixed version a long time ago.

I'm only looking to change it in the near future as I'd be needing a wide gamut screen and colour accuracy in Windows 7 is said to be better than Vista due to a new colour management system so that aspect will be interesting...

I have however had a host of alternative 24" screens, both VA and IPS based and in the end kept the Hazro as it gave the prettiest picture with the more accurate colour in sRGB once calibrated.
 
While I'm generally very pleased with this monitor, I must admit to getting a bit annoyed by the white glow effect on dark backgrounds while playing a game in a darkened room last night. As others have mentioned it looks initially like backlight bleed but it isn't.

Oddly, it isn't apparent all the time and when it isn't the blacks look really good for a TFT screen. It isn't a problem during the day though but I tend to play games at night in a dark room, in much the same way as I'd watch a DVD or Blu-ray that way too. I'm wondering if I'm sat too close to the screen or if some ambient lighting might help reduce it?

If it wasn't for this issue the screen would be nigh on perfect. I didn't know that these types of panels need a polariser to eliminate this effect; certainly none of the reviews I read that praised this monitor mentioned that it lacked one.

LOL you've just reminded me of my main complaint about this monitor, it's polarised at 90 degrees compared to my sun glasses. I have to tilt my head to the side to be able to see anything. :p
 
Here's an oddity...

I'm using the supplied DVI-to-DVI cable to connect my GeForce GTX 280 graphics card to this monitor and it displays the native 1920x1200 resolution perfectly. However, if I switch the resolution to 1920x1080 instead of the image being cropped with 60 pixel high top and bottom borders as you'd expect, it appears stretched to the full screen height and, thus, poorly scaled.

Is that normal? If not is there any way to change it so it uses 1:1 pixel mapping? It's not a big deal at the moment but it might be if I decide to connect my PS3 or Xbox 360 to it via HDMI.

I've connected my PS3 via HDMI and my 360 via DVI and both were perfect at 1080p.

It defo does 1:1. If it receives a non-native signal and/or non-digital signal the Image control menu becomes available... IIRC.

That's what I thought too but for some reason the monitor's OSD showed the resolution as 1920x1200 even though the NVIDIA control panel stated it was 1920x1080 and it was stretched poorly to the full screen's height (the width of 1920 pixels was obviously correct)! The Image Control option on the OSD was greyed out and unselectable because of this, i.e. the monitor saw the image as native 1920x1200 even though it wasn't. Incidentally when I turn my PC on and select the OSD while it's booting through the DOS screens prior to entering Windows it shows as 1920x1200 too rather than the expected 720x480 60Hz (or whatever).

I'm confused.

It's not a big issue though as I said but I wanted to try other screen resolutions to see how the monitor copes. Seems it just scales everything with the control panel showing the true resolution and the monitor's OSD showing 1920x1200 regardless.
 
Grr, ordering directly from HP is becoming a HUGE pain in the bum. I've been trying for nearly a week now, 5 attempts, 5 unsuccessful orders. All my payment cards keep getting declined with no reason given. :mad:

Anyone else who's ordering from HP having the same issue? :(
 
Anyone have any problems with running this monitor on Display Port instead of DVI?
It's just that I got a Radeon 4870 with DisplayPort after my 8800GT went bonkers, I'd like to use DP permanently now but I get an issue where the monitor won't work after I turn it back on after not using it a while (and if it auto-shuts down). It likes to say there's nothing connected to DisplayPort input.

EDIT:

I found the cause (most likely); it is my DisplayPort cable being faulty and HP should replace it - HP SUPPORT

Only problem I've had with DisplayPort is the very sharp edges of the cable putting a tiny nick into my monitor as I uncoiled it, flippin annoying!

As for the person having problems with scaling, check your NVidia Control Panel settings as if it's sending 1920x1080 down the wire as 1920x1200 it's handling the scaling itself and is probably set to "stretch".

It's funny you should ask...

I decided to order mine direct from HP using a 10% discount code (so it cost me £384 with free delivery) but when I clicked on the Order button my credit card transaction was declined. Ten minutes later I received a phone call from my bank claiming that an attempt to use my credit card fraudently had been made and so they'd locked the card immediately.

This obviously meant I could not order the monitor until they unlocked it. I asked them to unlock it temporarily so I could complete the order, which they did, and I received the monitor three days later. It has also gone through as a transaction on my new card. When I inquired as to exactly why my old card had been cancelled, I was told that it would compromise the investigation so I'm none the wiser as to what actually happened.

This has actually happened to me before, and this year too, when a Steam Games transaction failed to go through and I was then contacted by my bank an hour later at work that my credit card had been cancelled due to suspected fraud. Seems to me that if, for whatever reason, a transaction doesn't go through properly, say because the connection isn't very good, the credit card is flagged as compromised and subsequently cancelled. It's annoying but it's better than having someone genuinely get hold of my details I suppose.

My NVIDIA control panel setting is set to the default which is "Use my display's built-in scaling". There is a "Do not scale" option below it though so presumably I have to use this if I don't want the monitor to stretch the image for non-native resolutions?
 
Saw this posted in another forum and thought I'd share in case someone has been trying to use the DisplayPort cable that came with their HP...

HP said:
Advisory: HP LP2475w, HP LP2275w Widescreen LCD Monitor - Intermittent No Video Or Video Flashes On And Off When Using DisplayPort

DESCRIPTION
Monitors listed in the "Scope" exhibit intermittent video blanking (flashing on and off) or no video when using the DisplayPort (DP) video cables that were supplied with some of the monitors. The issue is caused by the video cable and is not related to the monitor design.

SCOPE
Information in this document applies to a small number of DP cables supplied with some of the following monitors:

Visit this link to find out if your HP supplied DP cable has the appropriate faulty part number...

http://h20000.www2.hp.com/bizsuppor.../mcc/loc/rbu_category_AdvisoryHPLP2475/alerts

I reiterate that HP are saying that the fault is with some of their supplied DP cables, it is NOT a monitor fault.
 
I'm having an occasional but puzzling issue with my screen resolution which has happened since I've had this monitor and I've never seen it prior to owning this screen. Basically I've had Windows boot twice from the machine being off with the screen resolution set to 1024x768 rather than the native 1920x1200. I then have to use the NVIDIA control panel to click on the Native Resolution button to fix it. I've perhaps turned my PC off then on over 20 times since I've had this monitor and it has only done this twice.

I'm using the 186.18 WHQL drivers for my GeForce GTX 280 graphics card and I'm connected using the supplied DVI cable. I did have the HP Display Assistant software set to load up with Windows (Vista x64 SP2) but have now disabled it.

Does anyone know what is causing this? As I said I've never encountered this with any other monitor I've owned so it can be pretty much traced either back to the monitor itself or the HP software I'd installed.
 
17 Brightness and 65 Contrast are the settings used by TFTCentral in their review. They also used the Custom Color setting with tweaked RGB values too (R 251, G 235, B 242 from memory). Looks pretty good to me even if the white backgrounds, such as websites and Word documents, end up looking a little murky/dirty (which might be the screen coating actually).

I know what you mean about the default brightness though... I actually felt an uncomfortable tingling sensation in my eyes when I looked at this screen for the first time, something I've never experienced with any other LCD screen I've had. Nice that it can go so bright but it can't be good for your eyesight at all on those settings.
