I've just learned that rtings.com is testing backlights on their TV reviews, under the Motion Blur section (see the backlight picture link). As far as I have seen, only the Sony TVs are PWM free. However, the Vizio sets and some of the Samsungs appear to use a more sophisticated form of PWM than...

Thanks for the clue on Sony. The best info I could find on sony flicker free TVs was this post at avsforum It looks like the Sony W700C or W800C may fit the bill, but are roughly $800 to $900 at the moment.

I've learned a lot about PC monitors from this forum, but I'm clueless about TVs, so I'm hoping I can tap into the collective knowledge of [H] to help me find some TVs that satisfy some or all of the following criteria. Unfortunately, I don't have the time to do a ton of research myself these...

A couple years ago I was able to return a Dell monitor simply because it gave me headaches. They were very good about it.

I can relate. Even a 27" 1440p is a bit big to me, since I dislike looking at the screen from an angle. I seem to prefer two or three smaller monitors, all angled towards my face.

Would you mind giving the time in the video where you see this? I'm guessing you're referring to the different shades of gray on the monitor to the left at around 1:51?

Supersnake, do you know if PCM sells to Canadians? Their site doesn't seem to say either way. Also, will they sell to individuals in addition to business? Thanks

I didn't try it myself, but I happened to bookmark an article on turning a Kindle DX into a secondary monitor: http://lifehacker.com/5928912/turn-your-kindle-into-a-second-monitor

Thanks all for your replies. Re: hyperthreading, it looks like all of these processors, including my current i3, are capable of HT. SSD prices have come down significantly since I last looked. I may try an mSATA drive while waiting for the next macbook refresh. Cheers

I currently have a thinkpad with i3-2310M (2.1GHz, 3MB L3), 8 GB RAM, 7200 RPM HDD, and am thinking of buying a new laptop, possibly a Macbook air with i5 (1.3 - 2.6GHz, 3MB) or i7 (1.7 - 3.3GHz, 4MB) or a Macbook Pro with i5 (2.4 - 2.9GHz, 3MB), both with 8GB RAM and SSD. I have looked at...

The Thinkpad T520 with the base 1376x768 screen circa Oct 2011 does not appear to use PWM. I am also looking for new laptops without PWM but information is sparse.

I'm in the market for a new laptop, and I'm having difficulty finding a list of laptops that do not use PWM dimming for their displays. Is anyone aware of such a list? If you know of any current (winter 2013) laptops that do not use PWM, please post! I'm particularly interested in...

I don't know what the best place in Canada is, but you can find a few Canadian resellers on Eizo's reseller page. I've contacted one of these resellers, Megatech, in the past and they've been very helpful with questions and quotes.

Hi IanM, The "9" is a wide-gamut monitor, while the "8" covers the typical sRGB space. According to the specs you linked the 9 also has a 12 bit LUT. Asus doesn't mention the LUT for the 8. I would expect the 9 to cost ~$100-150 more than the 8.

ninogui, can you tell us if prad found >9kHz PWM at all brightness levels, or if they found PWM only below a certain percent brightness? I remember tftcentral found ~9kHz PWM on the Dell 2413 when set to less than 20% brightness and no PWM at 20% or above (link). I'm wondering if the PB248Q...

Batjoe, would you mind doing a simple test for PWM once you have it?

I would be very interested in a super high PPI secondary monitor for reading, like the chromebook pixel screen mentioned above, but I'm not sure how well Windows (or Linux) would manage the very difft PPI of my main screen and such a secondary screen. I read a ton of text in PDF and would love...

Comparing black levels for similar luminance levels given by tftcentral for U2713HM, U2913HM (both AH-IPS) vs VP2770 and s27b970d (both PLS), it appears that AH-IPS has a slight edge in black levels. Perhaps the subjective difference in black levels has to do with the level of anti-glare and/or...

This amazon deal is nice. Does anyone have experience with using the Dell warranty when buying through Amazon or another third-party dealer? Do you get the same level of service as when buying directly from Dell? Thanks

I was told by a reseller in Canada that there is a US facility that would handle warranty claims for Canadians, but I have no further details.

I am in the same boat. Perhaps in time PWM free monitors will become more widely available. I think the Dell 2412 does more than 266Hz, and it can cause issues for sensitive people

If you are patient, you might be able to get the Dell U2713HM for just over $600. It was recently going for $630 through Dell Canada.

Does this suggest that PWM > 2000Hz is fast enough so the LEDs do not dim substantially, or does this simply suggest that people should not be able to consciously perceive the flicker at high Hz? If it's the latter, i think it may not be suitable for people with harsh physical reactions to PWM...

Dell Canada has this on sale today for $550 under their business section.

You would shudder to see the fingerprints on the iMacs at my university. It's a real horror show. Nothing beats underlining stuff on your monitor in ink, though. I thought this generation was supposed to be tech-savvy. Even my luddite father knows better than that!

Prad has reviewed this monitor. They will have certainly measured the gamut and probably made some comparisons to the U2713* series as well. You can pay 2.5 Euro now to view it online or wait until mid April for the free review.

I believe the 24" Eizo has an e-IPS panel (as in Dell U2412) and the 23" model has a PLS panel, so they are actually fairly different.

An employee with www.megatech-int.com told me that if you want to return the monitor within the first 30 days, Eizo will pay the shipping. After 30 days, you pay. Not sure if this policy is specific to this company, or if Eizo generally pays return shipping within 30 days. I have no info on...

I'm not sure if it is still available but the Eizo Foris FX2431 is a 24" 16:10 VA monitor that appears to be very nice, although IIRC also very expensive i think your width/height comparison might be off? i think a 27" 16:9 should be about 3 inches wider and 0.5 inch taller than a 24" 16:10.

Recently, Eizo's North American prices were dropped to fall more in line with the European prices. I was quoted $950 CDN for this monitor. Hopefully Eizo will align their prices in Australia soon as well.

I've been interested in this, but my optometrist has brushed it off. My glasses are about -6 strength, and I find reading a bit straining. Everything looks small and far away. In fact, monitors look about 2-3" smaller on the diagonal due to them! So, do you normally wear a -X strength...

abscenceoftruth, others, I keep hearing good things about amazon's return/exchange policies, but do you know if this applies only for products actually sold by amazon themselves, or does this go for products that are being sold through amazon by third parties?

The Thinkpad T520i with the base 1366 x 768 screen seems to be PWM free based on the finger/pencil wave test and the camera test outlined on tftcentral. I think this model is one generation older than the current T5X models.

No, I haven't called him yet.

I'm considering an Eizo, but Eizo's website has very little information regarding warranty service in North America. Basically, they just provide some contact info for a rep in California. I am hoping to collect a few Eizo warranty experiences from our users in the US/Canada. How did you go...

They've marked their updates with the word "update".

Not trying to hijack this thread, but could you explain briefly why TN should be calibrated to native white point? I've never heard this before.

tftcentral's review of the U2913WM is now up. Overall, it's pretty positive. They confirm the monitor is PWM-free, and they found no cross-hatching or buzzing. The uniformity compensation worked well on their unit, and the factory calibration was pretty good.
