SVA & UWVA display differences ?

[Ashokdb2k]

Hi,

HP 15.6" ProBook 450 G5 Notebook lists 2 display options as given below.

1. 15.6" diagonal LED UWVA Anti-Glare FHD (1920x1080) LED-backlit 

2. 15.6" diagonal LED SVA Anti-Glare HD (1366x768) LED-backlit 

Though the resolutions are different can someone please explain the difference between SVA & UWVA, what are the pros and cons of these display technologies ?

Thanks,

AK

I'm hoping someone from HP or with real knowledge will weigh in here because it's fairly improtant to understand differences between displays in laptops - they're a huge and crucial feature of these types of devices, ha. 

Not to spread misinformation but more to motivate such a specialized individual to set the record straight, these are some conversations which suggest that UWVA is usually or always an IPS panel, whereas SVA is usually or always a TN panel.

For Heaven's sake... can noone really answer this question here with any real authority?   I've been searching for an answer to this for a week now.   There are, in fact, more than a few comments across the web that purport to know that UWVA is HP shorthand for true IPS.   Yet HP sees fit to use "IPS" unequivocally in many other laptop models' specs.

Why introduce the confusion?

Two separate "live chat" sales support agents confirmed to me that Probooks are not available with IPS screens as an option.  I'd decided to take that as fact until I searched a littler further and discovered that it may not be correct .

I'm very interested in purchasing a certain config of 17 inch Probook rather than a similarly configured Envy.  The Envy lists a display option with IPS.   The Probook lists a display option with UWVA.   I'm primarily interested in the machine for photo editing.   For 1000 USD the probook on sale right now can be spec'd with superior components, but if the screen is a comparatively dim and less color true TN screen I may be disappointed.

SVA stands for Standard Viewing Angle. UWVA stands for Ultra Wide Viewing Angle. The wider the better. The more immersive the experience when you are watching movies or gaming.
