TN is never better for photo editing. IPS or similar is the only sensible option. TN viewing angles are so restricted that even on a small screen, the top will be too dark and the bottom washed out. This is not about manufacturer or price, it's a basic limitation in the TN technology itself.
And although I suspect all laptop panels are 6-bit panels with added frame rate control, this is another inherent limitation in the TN technology. True 8-bit TN panels don't exist.
Don't worry so much about gamut, unless it's exceedingly small. As long as you have basic sRGB coverage you'll be fine. Other things are much more important.
In any case, don't expect too much from any laptop display. It will never be in the same league as a decent desktop monitor, and the best solution is to have an additional separate monitor for stationary use. But of course that can come later.
Thank you very much
Also the IPS dispalys ( LG LP156WF4 or AUO B156HAN01) should be 6-bit. Is it a problem?
Did you see test results in the "Display" section of these link : http://www.notebookcheck.net/Review-Clevo-W650SJ-Schenker-M504-Barebones-Notebook.114329.0 .html ? Is it ok for a laptop display?
I know that a separate monitor would be the best solution, i will buy it as soon as i'll have enough room in my house for a stationary use
6 bit panels are more or less unavoidable in laptops, except perhaps in the more expensive ones. If I were to buy a laptop for the display only, I'd probably look at the MacBook Pros or some of the HP Dreamcolor options. The problem with HP is that they stuff an incredible amount of totally useless software into their machines, which can be difficult to clean out - but they generally make excellent hardware.
That LG panel does have a very small gamut, even considerably smaller than sRGB. Although I still think it's more important that the colors it can reproduce are accurate, I think maybe I'd look elsewhere.
Macbook pro is out of budget
Hp assistance said that in italy they don't sell laptop with dreamcolor (i'll call again tomorrow to be sure ) but i think that it would be out of budget (max 2000 euro).
They said that the best solution for me is the zbook 15 g2 (2300 euro), but they DON'T know brand and model of the display and if i can have SSD + HD inside the zbook 15 g2.
The laptop with the lg panel costs 1500 euro. the question is; "i know that the lg display is not the best, but is it almost sufficient for my use?". In this way i may save 500/800 to buy a separated display later.
I have read that dell xps 15 and dell precision m3800 have great display, but they are glossy and very reflective. Is it a big handicap?
Do you know the 3k 15,6" display Panasonic VVX16T020G00 ? It should be a 8-bit display with 72%NTSC gamut ( http://www.panelook.com/VVX16T020G00_Panasonic_15.5_LCM_parameter_22014.html )
Do you sugget me a 3k display for photo editing?
I'm probably not the right person to answer these questions, I haven't worked on a laptop for many years.
What I can say is, make the right priorities and the right compromises. A laptop display is always a compromise solution until you can get something better.
IPS is important, the viewing angle issue in TN is very real.
Things like 3k or 4k or whatever is wasted. If that's what you get, fine, but it's no big deal.
Gamut should be basic sRGB coverage, but anything more than that is again wasted (in a laptop; not in a good desktop display). NTSC coverage is a moving target, there are different ways to measure that. See if you can get a good solid figure for sRGB coverage. That said, 72% NTSC is a common way of expressing standard sRGB coverage.
Glossy can be a problem in bright surroundings, matte is always better. Glossy is a way to increase contrast, so it looks more snappy, but contrast is never really an issue. If anything, it's usually too high to begin with.
Bit depth is again a moving target. What's normally used in laptops is a 6 bit panel plus temporal dithering to give the illusion of two extra bits. These panels are always called 8 bit by the manufacturer. True 8 bit panels are mainly reserved for the desktop market.
I got that IPS matte is the best solution and the the laptopo display is always a compromise.
I chose the laptop: Santech c37. Now i have just to choose between the two possible displays.
Which one of them is the best for photo editing with photoshop and lightroom?
Here you have the review of the glossy version of the first one (i would buy the matte one):
Here you have the review of the second one:
Thanks a lot
