Do they think gamers are suckers?

[NickHeavy]

 

Can Optoma's UHD30 stand in for a gaming monitor? Does 240hz refresh rate look good on a big screen?

With HDR 10, 4k and a screen that can be as big as your wall, is it worth it to check out projectors again?

*looks at RGB market*

Gamers do be suckers tho.

Yes. And they're entirely correct.

Them -gamers are suckers

GAmers- nOO whEre nOT!

 

Also gamers

How much RGB can I cram onto this system with a 600$ budget????

 

Wait.... I'm a gamer...

I wish they would've shown that "bright mode". 

[Bumblebeepee]

I briefly had a UHD42, it was replacing a older Optoma projector i had and had a great experience with, but ended up returning it and getting a 4k TV instead,
The bright mode was excellent, its there for people who don't have rooms that can be fully darkened.

for model numbers (as they differ for Europe):
The UHD30 is equivalent to the UHD40, and has a 1.1x optical zoom (1.2:1 throw)
The UHD50 is equivalent to the UHD42, and has a 1.3x optical zoom and a optical vertical shift (1.5:1 throw).
The UHD30/50 has Mobile-HD link (MHL), whereas the 40/42 does not (for mobile phone streaming).

Two things that were not covered in the video were the very two reasons why I swapped to a TV (despite the smaller size),
Firstly, the colour reproduction is good for plain old RGB, but not as much for the blended colours between.

See the aqua blue colour in these Monitor vs Projector comparisons,

Both next to each other: (the room lights were off, all that extra light is reflected light from the projector when it was displaying a light grey test pattern)

It made the sky colours in the film Weathering with You look overly dull,
 

Projector test pattern:

 

Monitor test pattern (abit blurry, camera moved):

And secondly, the 4k is more of a blended "4k" due to the DMD shifting technique used to achieve it from a 1080p DMD. It was not able to give the same detail as a conventional DMD / LCD was able to.

Things that were 1 pixel apart are blended together.

 

Monitor:

 

Projector:

It really did just show a gray square for the alternating black/white single pixel line pattern

 

Pro's for Projector:

• Can be moved around with ease,
• Great brightness
• Huge projection area
• 240hz 1080p mode is fantastic,

Downsides:

• For 70-120" screens, you can get better image quality from a similarly priced/sized TV
• Colour reproduction
• Soft / non sharp 4k visuals 

Overall i'd still recommend it if you have a use case where a TV just isn't large enough, or if you plan to move it around, For other situations just get a huge TV.

"Projector manufacturers really need to stop making up meaningless numbers to describe their products"

 

yea ..kinda like how every other manufacturer of every other display type does, Its industry wide :P

 

Well , i say that ...but ..Monitors and TVs have got somewhat better in recent years, they still bend the truth somewhat, with claims of say 1000nits, when in fact when tested its only 850 for example, but its better than the BS 100,000:1 contrast (aka Dynamic contrast, aka utter BS).

 

IMO the most egregious example of BS marketing still around today with Displays is 'Response time' ..while they dont 'legally' lie, the figures are taken from a test so ridiculously 'broken' in favor of the advertisers that its totally useless for anybody who actually wants to know the 'real' spec.

2ms advertised ? ..really ? ..oh thats right its the fastest single transition out of usually more than 30, not the average, measured from 10% into a transition to 90% complete, running max overdrive, thus ignoring usually massive amounts of overshoot or the slowest part of a transition. That testing method misses out on so much data that displays with the same advertised response time can vary widely in actual performance. It means bugger all, yet soooo many people look at that spec and make purchasing decisions on it.

 

its a shame you guys at LTT dont yet have the capability to measure Pixel response accurately, i'd love to see you take these manufacturers to task by making a series of Vids that compare 'advertised' response time to 'real' response time.

Dude, thanks! Perfect quick post to show someone the deficiencies in "affordable" projectors.

I work in the AV industry, this video did a really great job in explaining how does the DLP work and how do all those “enhanced 4K” pixel shifting works!

 

I don’t own any Optoma project, but here is my guess and suggestion:

 

1. For the 4K in gaming mode, they stopped the quadruples pixel shifting but still does a double pixel shifting in diagonal direction, so the picture quality is still better than 1080p, hence the refresh rate is half of 1080p

 

2. We never use keystone since it decreases the quality a lot and also increase input lag for gaming since it adds extra graphic processing, instead we use Lens Shifting.

 

But unlike 3LCD projectors, for small DLP projectors, lens shifting usually does not exists. So for those who would like to buy small DLP for the better contrast ratio, remember to plan your projection ahead: If you can reverse mount the projector on ceiling with a adjustable mount (which can adjust the tilt, levelling etc), then you won’t have the blocking issue.

 

1 installation tip for non lens shift projector would be: mount the projector first, then use the projected image to align your projection screen, then you would have the perfect aligned non-keystone projection.

I'm using my 800x600 120Hz projector to watch this video. Calculated size is about 90 Inches. I use my apartment wall as a screen. I paid 3.00 USD for it.

Not to be nit-picky...but it's Faux-K not True 4k.  The chip itself is only using 1080p, but pixel shifting to generate a 4k image...while it might look better than 1080p, for myself it's like calling a 1080i signal true HD back in the day.

 

With that said, I'd rather spend money on a projector with 1080p, with lens-shifting rather than a 4k that doesn't allow keystones.  (Actually, anytime you use keystones you muddy the picture, as it's usually just compensating for the distortion in software)....actually, I would prefer a 3LCD over DLP colorwheel (I'm super sensitive to the rainbow effect)

 

As for the contrast ratio, instead of using contrast ratio I usually look at the Lumen output of a projector to gauge.

 

An example of this would be like the Epson PowerLite L510U; you can pick up a factory return one for $1500 CAD, or a brand new one for $1500USD on ebay...although the input delay might really suck (as it's usually not advertised).  The point being though, I'd rather have delayed input but a better image quality/brightness

Could you guys add a Epilepsy Warning, in videos like this one? Normally some of the videos like this one just give me a headache or migraine but this one caused a seizure.

[Nightfiend]

There were several parts that bothered me and I tried looking away and listen to the video but it didn't help. I honestly zoned out as I was going into the seizure and only remember bits and pieces. I'm not inclined to re-watch the video to find the exact spots. I do know that I had to look away when they were testing the contrast and playing Doom. I should have left the room or turned it off but hindsight is 20/20.
