Why you can trust Tom's Hardware
To read about our monitor tests in-depth, check out Display Testing Explained: How We Test PC Monitors. We cover brightness and contrast testing on page two.
Uncalibrated – Maximum Backlight Level
We rounded up the speediest monitors from our most recent reviews to compare against the ROG Swift PG259QN. All operate at 240 Hz or higher. In addition to the ROG Swift PG259QN, we have the Asus TUF VG259QM (280Hz), Acer XN253Q (240 Hz), Aorus KD25F (240 Hz), HP Omen X 25f (240 Hz) and Samsung C27RG5 (240 Hz), the lone VA panel. All others are IPS or TN.
Only the two Asus screens can do HDR, so they are understandably bright. The HP, Acer and Aorus monitors manage to top 400 nits as well. The Samsung is only a bit behind at 370 nits, which is plenty of light for gameplay or workday tasks.
The Samsung’s VA panel takes the black level contest, but the PG259QN is the best of the rest at 0.36 nit. It’s also the best of the rest in the contrast test with an impressive-for-IPS 1,265:1 contrast ratio. The C27RG5 has the broadest dynamic range at 3,354:1.
After Calibration to 200 nits
Our calibration (see our recommended calibration settings on page 1) did not reduce the PG259QN’s contrast by a visible amount (1,164:1 versus 1,265:1). It remained the best of the IPS and TN panels in our comparison.
ANSI contrast after calibration was also excellent at 1,084:1, which is above average for the IPS and TN monitors in our database. Here, the VG259QM has a slight advantage, but you’d be hard-pressed to see the difference. The Samsung, however, has a more three-dimensional and saturated picture.

Dayne_87 That's great, but I prefer resolution over frame rate. I have a 1440p Asus ROG 27" with 144hz and G-sync and I'm fine with that for now. If I were going to upgrade for that price I would want it to be at least 1440p 360hz or 4k 144hz or faster and still 27".Reply -
thepersonwithaface45 No idea why companies are focusing on high refresh rates at 1080p. This is the 4k generation, 2k was last gen and we should be getting more choices in the 4k range. Which I'm sure we will, but I don't see anyone paying $700 for a 1080p high refresh rate monitor when for $100 more you can get a 144hz 4k 27" monitor.Reply
Infact, this one is only 24.5"?
What? What is that price for that resolution, you're really just paying for 360hz? -
Jonagold What are all the included latencies in your Absolute Input Lag testing? Could there potentially be mouse button latency included? Also system latency? What are frame-times etc.?Reply -
ashburner This is for competitive gamers and that's it. They are notorious for running high framerate at low resolution. Even at 1080p, almost all effect settings are turned off. It's kinda crap to watch but it works for them. I prefer 2K at 27". I'm at 165hz now but I'm looking at a 4K 27". My 3080 should be in on Tuesday.Reply -
nofanneeded I dont know whats stopping Tomshardware from reviewing LG Oled 4K 55 inch TV for gaming ? it has everything one needs for gaming even Nvidia Gsync.Reply -

I should compliment Toms Hardware for improved mainstream-writing description of how motion blur is reduced -- doubling Hz halves display motion blur, as an alternative to strobing. Yesterday's media used to dismiss high Hz, or was not familiar with the benefits of high Hz.
I would, recommend that TomsHardware do pursuit camera tests with instructions at the forums:

Not necessarily. If you own a 120Hz iPad, you'll notice web browser scrolling is 2x clearer. LCD motion blur halves when LCD Hz doubles. And my 360 Hz monitor has 1/6th web browser scrolling motion blur of a 60 Hz LCD monitor.ashburner said:This is for competitive gamers and that's it.
I have the PG259QN here too, and it's absolutely lovely, especially when combined with the Razer 8000 Hz mouse (I have a prototype here).
4K was a $10,000 frivolity in 2001. Today, 4K is a $299 Walmart special. The mainstreaming of 120 Hz is slowly beginning this decade, with future iPhone/Android devices standardizing at least 120 Hz. But eventually, 240 Hz will be a freebie feature much like Retina screens.
We've almost retina'd out resolution, but we are far away from retina refresh rates. There is already a laboratory engineering path to an 8K 1000Hz display, though that will take many years of progress to reach.
High-Hz isn't just for esports anymore. Though the highest Hz is still expensive and mainly of interest to bigger-budget users. -

I was going to post about your site. My eyes hurt and I cringe every time i see sideways pans in films and I check your site from time to time to see how the race to 1000hz is going. I get why these people like higher resolutions, but even back in the day of the 3DFX Voodoo1 and Voodoo2 SLI I preferred higher framerate over the resolution bumps. I want to see that 1000 hz target hit and this is a positive step that moves the bar even if just a bit towards the goal we need in display technology.mdrejhon said:Founder of Blur Busters / Inventor of TestUFO here.
