The 75EQ3EA is a 75 inch 4K TV from Sharp, launched in the year 2022. It features a 10-bit VA panel. The max. resolution it can achieve is 3840 x 2160 @ 60 Hz with a pixel density of 59 ppi.
Picture Quality
After screen size and resolution, the very next feature of a display that impacts picture quality is Color Gamut.
Speaking of which, this TV is rated with a DCI P3 coverage of 94%, which is equivalent to 128.18% sRGB coverage. The color quality on this TV should be Lifelike!
What is Color gamut ?
Color gamut spec of a TV is the measurement of the range of colors that the TV can show.
A panel with poor color accuracy will produce washed out colors that will spoil your immersive experience.
It is specified in different units - sRGB,sRGB (standard RGB), NTSC, DCI P3 etc.
For example, the color gamut of this TV is specified in DCI P3.
But don't worry, here is a chart that will help you choosing a TV with good color accuracy.
Other than color accuracy, you should look at the static contrast specification as it influences the picture quality substantially.
The importance of static contrast ratio
A TV with high enough static contrast ratio will produce deep blacks while a TV with low contrast ratio (<1000:1) will produce images that may look muddy as shown in the below image.

As you imagine, this will affect your experience considerably.
Also, a TV with high constrast ratio allows you to see more details. So, resolution and static contrast ratio go hand in hand in a sense.
If given a choice, I will prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
Sharp did not list a static contrast ratio specification for this TV. Here we have to make an assumption. For a TV with VA panel, the static contrast ratio will surely atleast be 3000:1 or above So that's a plus.
HDR is also supported on this TV in form of Dolby Vision, HDR10 and HLG (Hybrid Log Gamma).
Coming to brightness, it can go as bright as 500 nits. The backlight of this TV is powered by Direct LED technology.
Gaming Performance
If you are going to use your TV other than using it as a TV — like as a PC monitor or Gaming, make sure to take a TV that features the lowest input lag. For gaming, both the input lag and response time affects the performance.
Sadly, there is no specification for input lag on this TV. Now, since this is not a cheap TV from Sharp, input lag on this TV could be 20ms or below.
What is Input lag ?
This lag is the amount of time at which device inputs changes the content of the TV. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
Although for better experience, get a TV that has an input lag and response time of less than 20ms.
Dimensions and Ergonomics
Vertically, the TV measures 75 inches and horizontally 65.83 inches.
Coming to thickness, it is just 2.93 inches thick. It weighs around 27.4 kilograms. So plan your space accordingly.
Coming to ergonomics — If you plan to wall mount the TV, you can make use of the VESA mount provided with this TV, which by the way has an interface size of 400 x 300 mm. However, there is no Swivel, Tilt or Pivot feature support on this TV.
